My Sister Mary

by MikeyBear


	"Harder.....Harder," Mary whispered in my ear.  I responded by driving my steel hard cock deeper into her soaking wet cunt.  Mary was straddling my hips, her short red skirt pulled up over her firm ass cheeks.  A pair of silk panties laid on the floor next to the couch where we were hurriedly making love.  She was whispering so she would not alert her two daughters, who were supposed to be taking a bath.  The only sound was our hard breathing and an occasional slap of flesh as I buried my self deep into her.  I could feel the cum begin to rise up from my balls, and propel itself deep into her golden-haired vagina.  She buried her face into my shoulder as an orgasm swept through her body, her pubic muscles milking the jism from my cock.  As her spasms subsided, we kissed passionately, our tongues fighting with each other.  
	Mary slowly raised herself off of my now limp cock.  Her small, firm breasts, the quarter sized nipples still hard and covered with my saliva, stuck through her unbuttoned blouse.  Although she will turn forty later this year, her body was still as firm as any eighteen year old. "Thanks," she said, "I really did need that."  "Now hurry and get cleaned up so we can get back over to Mom and Dad's house."  I stood up and slipped off to the bathroom, holding my pants up with my hand so I wouldn't get any of our juices on them.  
	Jill and Jeri, Mary's seven year old twins had gotten into Dad's garden at our parent's house and gotten filthy.  We were in the middle of a family reunion and Mary had asked if I wanted to come along while she ran them home to get a quick bath and change clothes.  As soon as the two girls were safely in the tub, we had jumped each other, not even bothering to take off our clothes as we passionately made love.  Our love affair has been going on for almost thirty years now.  Even though I live up north and only make it home about once a year, we always find a chance to renew the passion we have known since we were kids.  We both are married and have our own families, but our spouse's will never have the special bond and passion that flows between my sister and I.


*******  *******  *******
Chapter One

	Our story began twenty nine years ago in the summer of 1967.  I was twelve years old and Mary had just turned eleven.  We were born only thirteen months apart and had always been good friends and playmates.  We lived in a mid-sized industrial city in the upper south.  Although we lived in a suburban area, none of the kids who lived real close to us were our age.  We had been born at the end of the baby boom, and most of the neighbor's kids were in high school and starting college.  Our father was an engineer at the big industrial plant in town, and our mother stayed at home with us.  We lived in a modest split level house.  Our bedrooms shared a common bath at the end of the hall..    
	Our little brother David was born in the spring of 1967.  Our parents had sat us down and explained where babies come from soon after Mom found out she was pregnant.  One day soon after school was out for the summer, Mary and I were playing in the treehouse that Dad had built for us.  It was built in a large oak tree near the back corner of our property.  The tree house was about six feet square with a roof and windows on each side.  We had taken old blankets and pillows we had found in the basement up to it so it was very comfortable.  Mary had to go inside to use the bathroom, but quickly came running back to the treehouse.  "Come on," she said, "You have to see this."  I followed her to the back door of the house.  She put her finger to her lips and motioned me to be quiet.  We eased open the back door and slid into the house.  
	Mary and I tip-toed across the kitchen floor to the top of the stairs.  We could see down into the den through the railing. Our house did not have air conditioning, so it was very warm inside.  I guess it was because of the heat and the fact that we had been playing outside that Mom had taken off her blouse and bra, and was nursing David topless.  Before this, she had always been very careful to go into the nursery and close the door before nursing him.  Although I had seen plenty of pictures, I had never seen a grown woman's breasts in real life.  My mother was a very petite woman, but her breasts seemed huge.  They were capped by nipples that must have been two inches across.  As we watched, Mom shifted the baby from one breast to the other.  The nipple that he had been sucking at was hard and stuck out about a half inch.  I could feel my dick rising in my shorts as we watched.
	After watching this for a couple of minutes, Mary touched me on the shoulder and motioned for us to leave.  We slipped back out the door and ran across the backyard toward the treehouse.  As we climbed the ladder, I looked up and caught a glimpse of Mary's white panties up the leg of her shorts.  Mary sat down on one of the pillows, and I laid face down next to her on a blanket, trying to hide the bulge in my shorts.  "Did you see her boobies?" Mary said. "I hope mine get that big someday."  
	This surprised me because Mary had never said anything of a sexual nature to me before.  Even though we shared a bathroom, I had not seen Mary naked since we were 3 or 4 years old and still took baths together.  She always locked the door on my side of the bathroom whenever she was in it.  We had never played "doctor" or anything else.  Over the last year I had tried to get a peek at her as she dressed, but had not had any luck.  As we talked about what we had seen, my hard-on continued to throb.  I desperately needed to jack off.  I was hoping that Mary would go the house to pee as she was originally going to, but she continued to talk about seeing Mom nurse the baby.  Mary moved down and laid down on the blanket next to me.
"I wonder what it feels like?" Mary asked.  "She looked like she was enjoying it," I replied, "It almost looked like she was asleep."  Mary closed her eyes and reached up and rubbed her hand over the small bump in her T-shirt where her breasts had just began to swell.  
	My cock was rock hard, and straining to get out of my underwear.  I reached down and rubbed it, the sensations jolting through my body. I reached up the leg of my shorts and pulled it out of the restraints of my underwear, hoping to ease some of the pressure.  As I pulled it free of my briefs, I could hold back no more as thin streams of almost clear cum began to erupt from the head, spattering on Mary's legs.  Mary quickly sat up and looked down at her legs.  My hard cock was still in my hand, and a thin stream of cum spit out of the head and landed on her leg.  She pushed me back and scrambled out of the way.  "You peed on me!" she yelped, " I'm telling Mom!"
I grabbed her and pulled her back down on the pillow.  "I 	didn't pee on you," I said.  "That's what happens when a boy gets excited."  
	My hard-on was still hanging out of the leg of my shorts, and a drop of cum still hung on the bright red head.  "I couldn't help it," I continued,  "It just happened."   Mary was staring in fascination at my hard cock.  "Your thing is all big and red," she said after a few moments.  "That's what happens when I get excited," I repeated.  "What made you excited?" she asked.  "Seeing Mom's titties," I replied, "I've never seen real ones before."  Mary looked at me questionably so I went on.  "Remember when Mom and Dad told us about where babies come from."  Mary nodded.  "Well when a boy sees a girl's titties, his dick gets all hard and excited."  "His dick?" she asked.  "That's what you call a boy's thing," I answered.  By this time mine had wilted and disappeared back up the leg of my shorts.  "Then the boy puts his dick in the girl's pussy.."  "Pussy?" she asked.  "Your pee hole..."  and then he shoots his stuff in her to make her have a baby."  "I don't believe you," Mary said, "That thing wouldn't go into my pee hole, it's too big."  "Yes it will," I replied, "I've got pictures to prove it." "Where?"
	Our conversation was suddenly broken up by Mom calling us in for lunch.  We left the topic hanging as we ran inside.  Mom had put her blouse and bra back on, but I could see a small wet spot where one of her breasts was leaking.  Mom announced that we were going to the community pool that afternoon, so I didn't have a chance to prove anything to Mary.

Chapter Two

The next afternoon, Mary and I were back in the treehouse.  I had brought with me my favorite jack off pictures.  They consisted of three old black and white pages from a porno magazine that one of my friends had swiped from his brother.  They showed various pictures of a big titted blond woman fucking and sucking a guy.  One picture even showed him stuffing his cock up her ass.  I kept these pictures hidden in the cutout pages of an old book in my bedroom.  
	"See...I told you that's what happens," I said proudly.  I pulled the pictures from my pocket and carefully spread them out on the floor of the treehouse.  Mary looked at them with amazement in her eyes, slowly turning them over and looking at all of them.  "I still don't see how you can get your thing inside a girl's pee hole," she said.  As we looked at the pictures, I could feel my dick start to harden inside my shorts.  As I reached down to adjust it, Mary noticed and asked, "is your thing getting all big again?"  I nodded yes and quickly pulled my hand out of my shorts in embarrassment.  "Can I see it?" she asked.
	I was shocked to hear that, but I slowly pulled my shorts and underwear down over my hips.  My hard-on sprung back up against my belly.  Mary gasped but could not take her eyes off of it.  She slowly reached out her hand and touched it with a finger.  A drop of pre-cum appeared on the blood engorged head.  "Use your whole hand," I said, and reached down and wrapped her fingers around my five inch erection.  "Not too tight," I said as she squeezed a little too hard.  I showed her how to move her hand up and down.  "This is how you make a guy cum," I said.  "Cum?" she asked quizedly.  "Like yesterday when you thought I was peeing."  "Oh, you mean when that stuff comes out of your .....dick?" she asked haltingly.  "Yeah, that's what Mom and Dad were talking about when they told us about the sperm and egg stuff," I replied.  Mary continued to stroke up and down on my rock hard cock.  "Don't stop, I'm going to cum!" I moaned as the sperm rose up from my balls and began to erupt from the slit in my cockhead.  Mary just stared as spurt after spurt of the clearish liquid spewed from my cock and dribbled down her hand.  Her hand never stopped moving up and down, milking the cum from my dick.  It was the first orgasm I had ever had that had not been courtesy of my own right hand, and it had been very intense.
	Mary finally let go of my shrinking cock and wiped her hand on one of the blankets that lay on the floor of the treehouse.  I was sitting on one of the pillows with my shorts and underwear around my ankles.  "Now you have to show me your pee hole," I said.  "Mom said I shouldn't ever show it to anybody," Mary complained.  "Well she said I shouldn't ever show anybody my thing," I replied, "but I showed it to you."  Mary thought about this a second, then reluctantly got to her knees.  She unsnapped and unzipped her pink shorts and slid them down her legs.  I can still remember the white cotton panties she wore underneath.  A small spot of moisture had soaked through at the junction of her slim thighs.  "The panties too," I demanded.  She hooked her thumbs into the sides of the white cotton and pushed them down to her knees.  By this time I had shaken my shorts off my legs and was sitting in just a T-shirt.  
	Mary sat back down, and I reached over and pulled her shorts and panties off.  She was shyly keeping her legs together, but I put my hands between her knees and spread her legs apart.  Her hairless slit was puffy and pink.  I scooted up closer to her and ran my hand up her thigh.  I was finally going to get to touch a real live girl's vagina.  Mary recoiled a little but let me have my way.  I ran a finger up the length of the small slit, feeling the heat and a slight wetness.  Mary's thighs seemed to part a little more.  I put some pressure on my finger and the pink lips of her pussy opened up.  My finger slid to the bottom of the slit, and barely entered the small opening.  I did not even get up to the first knuckle before I met resistance.  Mary let out a little moan, and my finger seemed to get a little wetter.  Using my other hand, I spread the lips of her cunny more so I could get a better look.  I noticed for the first time the small pink bump at the top of her slit.  I also notice a few blond hairs that had sprouted just above the slit.  I moved my thumb up and nudged the pink bump, causing Mary to flinch and moan audibly.  
	"Do that again," she said through clenched teeth.  I dipped my finger into the moist hole to lubricate it, then began to slowly massage the flesh around the bump.  Mary began to shiver and twist as I massaged her tiny clit.  I continued to rub the bump, occasionally dipping my finger down to her vaginal opening to gather more moisture.  Her juices were now running down the crack of her ass and making a spot on the blanket under her.  After about two minutes of this , Mary arched her back and moaned loudly.  "Ohhh...Ohhh....OHHHHHHHH!" she gasped and pushed my hand away from her.  I sat back and watched as she squirmed on the blanket for a moment, her thighs tightly clenched together.
	Mary laid there for at least five minutes, her thighs slowly parting and her legs relaxing as she recovered from her first orgasm.  Her hands had moved up and she was rubbing her small breasts, or at least the nipples, which were standing out hard against her T-shirt.  As I laid down next to her, she rolled over and put her arms around me and hugged me close.  My hard again pecker slid right between her thighs, and I could feel the wetness and heat as it settled in her slit.  We ground out hips together, and I could feel my head of my cock slip into the tiny opening of her pussy.  We laid there for a minute as I gently tried to push my cock just a little deeper into her opening.   "MARY," my mother yelled from the back door, "TIME FOR YOUR PIANO LESSON!"  We quickly rolled apart and grabbed at our pants and underwear.  I think Mary set a record for getting dressed.  Luckily, we had never taken off our shoes and socks.  
	Mary quickly climbed down from the treehouse and headed for the house.  I reached down and picked up the pictures that were still laying on the floor.  I pushed my shorts back down off my hips and grabbed my hard cock in my right hand and stroked it until I came again.   For the first time in my life, I was thinking of something other than those pictures as the sperm erupted from the slit in my cockhead.  After wiping myself off on one of the blankets, I pulled my shorts back up and headed for the house.

Chapter Three

	Two weeks passed until we had a chance to meet again in the treehouse.  Mary had spent a week at church camp, and the following week I had taken my turn at the camp.  Since I was the only one at the camp from my area, I was able to brag that I had touched a girl's pussy.  I just didn't tell anyone that it was my little sister's.  I was the stud of the camp, and had even gotten one of the girls to go the lake with me for some making out.  Daphne had let me tongue kiss her and even let me feel her small breasts through her blouse and bra.  But when I had tried to unbutton her blouse to get inside she stopped me and told me she wasn't that kind of girl.
	On the night I got home, I was taking a shower in our shared bathroom when the door quietly opened and Mary peeked in.  "I've got something to show you," she said, "but it will have to wait until tomorrow."  I was standing in the shower after cutting off the water, and Mary was looking at my shriveled cock.  The memories of our last encounter in the treehouse flooded back into my mind and my dick began to grow.  We heard a knock on my door, so Mary quickly jumped back into her room and closed the door.  Mom walked in bringing some clean clothes.  I quickly shut the door to the bathroom so she wouldn't see my hard-on.  
	Just after lunch the next afternoon, Mary and I headed for the treehouse.  Mom was putting David down for a nap, and told us to play quietly so we wouldn't wake him.  As Mary climbed the ladder above me, I looked as usual to see if I could see her panties up the leg of her shorts.  I saw a quick flash of pink cotton just before she scurried into the door of the treehouse.  As I climbed in the door, Mary was pulling the blankets and pillows out of their box and spreading  them on the floor.  As I sat down on a blanket, Mary unzipped one of the pillow covers and pulled out two thin paperback books that she had hidden inside.  "Kimmy found these in a trash can at camp," she said excitedly as she handed them to me.  The Wedding Night was the title of the first one.  It was a slim book with a white cover.  I opened it and looked at a picture of a woman in a long white gown.  "It's all about sex and stuff," Mary said.  As I flipped through the pages, I paused to read occasionally.  The book described how a "modern woman" should react on her wedding night.  "Your first session of intercourse may be painful, as the hymen must be torn before your husband's penis can be fully inserted into your vagina," read one passage.  "A small amount of blood may appear as the hymen is broken."  It went on to describe the entire sexual act.
	"Did you read this?' I asked as I flipped through the pages.  'Yeah, Kimmy and I read it at camp and she let me keep it."  Kimmy was our cousin who lived across town.  She was the same age as Mary.  "It sounds kinda scary," she said, "but it says it's all natural and you should learn to enjoy it."  I set that book down and picked up the other one.  There was a picture of a girl in a nurse's uniform on the front.  Her top was unbuttoned and her large breasts were spilling out of her bra.  Night Nurses was the title.  I recognized this as a "fuck" book.  I opened it up and began to read.  "Gwen tensed as Doctor Bob ran his hand under her skirt and up to her soft ass cheeks," I read aloud, "His finger slipped under her panties and found the wet furrow of her soaking pussy."
I could feel my dick harden as I read a few more lines.  "Gwen dropped to her knees and began to loosen the drawstring of Doctor Bob's surgical pants," I continued, " She pulled his scrubs over his hips, revealing his massive nine inch hard cock.  She began to kiss and lick the purple head, pausing occasionally to take the length of it into her mouth and down her throat."
	By this time, my own swollen cock had formed a tent pole in my shorts.  "You're all hard again," she said as she stared at my crotch.  She leaned over and put her hand on my hard pole.  She looked at me and asked, "Can I make you spit again?"  " The word is cum," I said.  I quickly pushed down my shorts and underwear as Mary grabbed on to my five inch hard-on.  I laid back on the blanket as Mary stroked up and down, using some of the pre-cum that appeared on my cockhead as lubricant.  I could feel the sperm start to boil in my balls as she jacked me off.  
	"Hold on a second," I said, putting my hand out to stop her.  I slid my hand up the leg of her shorts to her panties.  "You're all wet too," I said.  "It feels all tingly down there," she said.  I reached over and pulled her shorts down off her hips.  Mary sat down and pulled her shorts and panties off.  I also started pulling her T-shirt over her blond head.  "I want to see what your titties look like," I explained.  Her pink nipples were the size of quarters, topping mounds that had begun to swell just a little.  The middle of her nipples were the size of a pencil and were sticking out.  I reached up and touched one of them, and it swelled and hardened under my touch.  "Take your shirt off too," Mary said.  I complied, pulling my tank top over my head.  We were now both naked except for our sneakers and socks.  (Several years later we talked about how we always left our shoes and socks on in case Mom called.)
	Mary laid down beside me, and we began to explore each other's body.  I was fascinated by her nipples, which had hardened into pencil size nubs about a quarter-inch long.  I bent down and tentatively stuck out my tongue and began to lick at one, as I had seen in my porno pictures.  I gently took it into my mouth and began to suck on it, much like I had seen my little brother nursing at my mother's breast.  The tiny pink bud seemed to stretch another quarter-inch before I switched to the other nipple.  Mary's hand pulled me against her chest as I licked and sucked at her nipples until they had turned a dark red color.  My free hand was moving up and down Mary's back until I finally settled it on her firm rear end.  My hand slid down the crack of her ass until I found her wet pussy slit.  Having no real idea about female anatomy, I began to rub the area around this wetness.  I didn't realize that what I was actually rubbing was the tight opening to her ass where her juices had run down.  She was squirming and letting out small moans as I tried to force my finger into what I thought was her pussy.
	I was beginning to wonder how a man could get his dick into such a tight opening when her sphincter eased up and my finger slid into the tight rosebud.  Mary gasped, "That's my pooh hole," as my finger slid all the way in.  I quickly pulled my finger out in horror and began to wipe it on one of the blankets.  "It's OK," she said, "It really felt strange, but good." "Will you do it again?"  I moved my hand back down to her ass and began to probe at the tight hole again with my finger.  The muscle eased and my finger slid back into her ass, which was slick with her pussy juices.  Mary squirmed and bucked up against me as my finger probed deeper into tight rosebud.  As she pushed against me, I felt my steel hard cock begin to slide between her lips of her hairless cunny.  Just as I  thought I might slip into her tight, wet pussy, Mary reached down and began to pull on my cock.  
	It only took a few seconds, and I was spurting my cum all over her belly and cunt.  I sucked hard at one of Mary's nipples and pushed my finger as deep as it would go into her ass, squirming it around as I pushed.  Mary kind of collapsed against me as I rolled onto my back.  We laid there for a minute, my finger still buried in her tight butthole.  I slowly started to ease it out, and Mary gave a small gasp as it finally popped out.  "That felt really good," Mary said.  We rolled apart, and both looked down at our laps.  Streaks of cum covered our bellies.  My dick had softened and shrunk, but Mary's pubic mound was still red and wet.  I slid my hand down and began to rub her bump, which was still moist with her juices.  In about a minute, she began to squirm, and soon she arched her back and moaned as an orgasm swept through her tiny body.  
We laid on the blankets for several minutes, my arm around her shoulders and her head laying on my chest.  I was softly stoking her still hard nipples with my fingers.
	After a few minutes, Mary asked what time it was.  I looked at my watch and realized that David would soon be up from his nap and Mom would be looking for us.  Mary wiped her belly off as best she could with one of the blankets, and we hurriedly got dressed.

Chapter Four

That night, after dinner, I helped Dad mow the yard, while Mary was busy with Mom in the kitchen.
After we had finished our chores, we all settled down in the den to watch TV.  Since it was summer, our parents let us stay up until 10:00.  After watching a couple of sitcoms, a movie came on that Mom & Dad wanted to watch.  It turned out to be a love story, so Mary and I were pretty bored.  I was laying on the floor reading a book, and Mary was sitting in the recliner reading one of her "teen" magazines.  Mom and Dad were sitting together on the couch.  Occasionally when I would look over at Mary, I would notice that her hand seemed to be rubbing at the crotch of her shorts.  
	At 10:00, Mom sent us off the bed.  I continued to read my book until I saw the light in the bathroom go off.  After a few minutes, I got up and put on my pajamas and went into the bathroom to pee.  I thought I heard a faint moaning from Mary's room, so I switched off the light and cracked open the door to her room.  I could see in the light from a streetlight outside that Mary was rubbing her cunny.  I watched for a couple of minutes, then she began to rub real fast.  She arched her back and let out a low moan as she came.  My own dick was rock hard by this time.  I gently closed the door and eased back into my own room.  Pushing my pajamas down, I started to jack off, thinking about Mary and her bald pussy.  I knew that one day soon I would be able to get inside her and fuck a girl for real.  As the jism began to spurt from my cock, I thought I noticed the door to the bathroom close.  Mary had been peeking just like I had been!  I got some tissues and wiped the cum from my chest and stomach.  
	I continued to lay there, thinking about Mary.  After a little while I heard Mom and Dad come up the stairs to get ready for bed.  The door to my room opened and Mom looked in.  I quickly shut my eyes and pretended to be asleep.  The door closed and I heard her look into Mary's room also.  I laid there for another fifteen or twenty minutes when I heard my Dad moan.  Since the baby had been born, they were leaving their bedroom door open so they could hear when he woke up.  I got up and went to my door, quietly opening it an inch or two.  I heard another low moan.  Very quietly, I opened the door and slid out into the hallway.  A dim light from the nightlight in David's room illuminated the hall.  The door to my parent's room was open about a foot.  I crawled down the hall until I could see into the room. 
	I almost gasped in shock when I looked in.  The light from their bathroom partially lit the room.  I could see Mom laying naked on the bed.  Dad was laying between her open legs licking at her pussy!    As he lifted his head from her crotch, I could see that Mom's pussy was covered with a thick mat of dark hair.  Dad wrapped one arm around her leg, and using his hand opened up her pussy lips.  His head dipped back down and he began to flick at her with his tongue.  Mom was squirming around on the bed and trying to be quiet.  Dad's other hand moved up her body and he began to massage her milk-swollen tits.  "Careful," I heard mom say, "They're kinda sore from nursing."  Dad rolled her tit around with the palm of his hand.  Her nipples were hard and stuck out about and inch.  He slowly began to kiss his way up her body until he  reached her swollen globes.  He took her right nipple into his mouth and began to suck!  I could see that his hand was now in Mom's lap.  He slowly inserted a finger into her pussy and began to pump it in and out.  This continued for a minute as Dad nursed at her breasts, first the right, then the left.  	Soon, Mom pushed Dad off of her and onto his back.  His hard-on was sticking straight up in the air.  Her hand went down and wrapped around it and she began to slowly stroke up and down the way Mary had done to me that afternoon.  She then bent her head down and took the end of his hard cock into her mouth!  My hand was stroking my own hard cock as she began to slowly bob her head up and down on his hard rod.  Her hand was still stroking the part of his enormous erection that she could not get into her mouth.  I could hear soft slurping sounds as she sucked on him.  Occasionally, she would take it out of her mouth and lick around the head like a lollipop.  Dad had one hand on the back of her head, and the other was twisting in the sheets, trying to be quiet.  After a couple more minutes of sucking, Dad lifted her head up.  Mom let his cock pop out of her mouth and it slapped back against his stomach.  She raised up and straddled him.  Reaching between her legs, she pried back his cock and positioned it at the entrance to her hairy pussy.  
	As she slowly lowered herself onto him, my own cock began to spurt it's seed.  I quickly flipped it back into my pj's, hoping that none of it got onto the carpet.  As I looked back into their room, Mom began to move up and down on Dad's huge cock.  It must have been eight or nine inches long, much longer than my measly five inches.  Dad was thrusting up into her.  At the same time he was massaging her huge breasts!  I thought I saw something squirt out of her tits into Dad's face.  His tongue was licking at his lips and cheeks.  After a couple of minutes, he pulled her down to him.  He then rolled over until she was underneath him.  He began to thrust himself deep into her wet pussy!  I couldn't believe I was seeing my own parents fucking.  Mom began to moan a little louder and Dad's thrusting became quicker.  "I'm going to come!" Dad whispered loudly as he slammed into her harder.  Mom raised up to meet his thrusts, and pulled his head down to kiss him.  Even though they were trying to be quiet, moans escaped from them both as they reached their orgasm together.  Dad collapsed on top of Mom, and they lay there kissing one another.  
	As I started to slip back to my room, I heard a squeal from David's room.  He was awake!  I turned and quickly crawled back to my room and closed the door.  I held the doorknob until I heard Mom go into his room to pick him up.  I gently eased the knob closed and quickly crawled back into bed.  My pajamas were wet and sticky from the cum I had exploded into them.  I grabbed some tissues and cleaned up myself as best I could.  However, I knew that mom would be able to see the cum stains on my shorts if she looked close enough.  I just prayed that she would be in a hurry and not notice them.  I could hardly wait to tell Mary what I had seen!

Chapter Five

	It was five days before Mary and I could meet in the treehouse again.  Three straight days of rain had kept us inside and under Mom's watchful eye.  Then the weekend had come and we had all our weekend chores to do while Dad was off.  Just after lunch on Monday, Mom told us to go outside and play so the baby could take a nap.  I told Mary to meet me in the treehouse; I had something to tell her.  
	I went out to the treehouse and spread out the blankets and pillows on the floor.  I then pulled the "fuck book" that Mary had found in a trash can at camp out and started to read it.  The part of the book I was reading was about a young nursing student who was losing her virginity to two interns.  My dick was straining against my underwear when I heard Mary coming up the ladder into the treehouse.  She looked at the book that I was reading and a smile crossed her face.  
	"What is it you wanted to tell me?" she asked.  I started telling her about the other night when I had seen Mom and Dad fucking.  Her eyes grew wide as I told her about Dad laying between Mom's legs licking her pussy.  "He licked her pee hole?" she asked in amazement.  "Yeah," I replied, "just like they talk about in this book."  "Listen to this," I said, and began to read from the book.  "Steve ran his tongue up the young nursing student's thigh until he reached her wet slit.  He pried open the pink lips and began to slowly slide his tongue into her moist hole, tasting her sweet juices."  "Gosh," Mary said, "that sounds kinda gross."  "Mom sure seemed to like it," I replied, and told her about the way she was moaning and squirming on the bed." 
Now came my big chance.  "Would you like to try it?" I asked.  Mary seemed to hesitate for just a second, but then a smile seemed to break across her face.  "Sure...I guess so," she replied.  We looked at each other a little awkwardly.  "Come here and lay down against this pillow," I directed.  As she walked up to me, I reached up and pulled down her pink shorts.  Underneath them was a pair of pink bikini panties with little bears on them.  "Do you like my new panties?" she asked.  "Mom got them for me at the store last week."  The main thing that I noticed was that they were pulled up into her cunny, and a small moist spot was starting to appear. "Yeah, they're cute," I replied as I hooked my fingers into the waistband and pulled them down over her hips.  Her bare cunny, with just a few thin blond hairs above the slit was already puffy.  I helped her lay down on one of the blankets with her back propped up against a pillow.  I maneuvered myself between her legs, pulling them apart at the knees.  I ran my hand up her thigh and gently over her small mound.  A shiver ran through her body as my finger parted her lips and nudged her clit. (I now knew what it was called from reading the wedding night book.)   
	Situating myself between her thighs, I began to follow the story from the book.  I gently licked up her thigh until her bald cunny was staring me in the face.  I cautiously stuck out my tongue and put it against her pink lips.  Mary jerked when she first felt my tongue on her.  I again bent down and took a tentative taste of her young pussy.  The taste was more tart than the "sweet juices" mentioned in the book, but not bad at all.  I began to run my tongue up and down her puffy slit, making sure to flick at the bump at the top.  Gathering my courage, I moved my face down and tried to stick my tongue into the hole at the bottom of the slit.  There was a lot more juice down there, and my tongue easily began to slide up into her passage.  
Remembering what Dad had done, I ran my arm over her leg and used my fingers to hold the lips spread.  This gave me my first close-up look at my sister's virgin cunt.  The lips had become larger, and a darker pink in color.  At the bottom of the slit was a shimmering hole, its inner lips just barely split.  At the top of the slit, her bump had become a small button, it's bright pink head peeking out from its protective hood.  I raised up and flicked at with my tongue, then tried to suck it into my mouth as if it were a straw.  I felt Mary's hands on the back of my head, pulling me harder into her cunt.  I sucked on her clit again, and her back arched up as she ground her pussy into my face.  
My hand had slid up under her shirt, and I was massaging her little hard nipples just the way Dad had done to Mom.  I then felt the familiar quake of her small body as she began to orgasm (another word I had learned from the book).  I tried to keep licking her pussy, but she pushed my head away and clenched her thighs together tightly.  My face was covered in her juices.  I continued to massage her hard nipple until she finally laid back and let out a big sigh.  "Ohmigod," she said in a hushed voice.  "I've never felt like that, even when I rub myself," she whispered.  I laid down beside her and put my arms around her.  She looked at me for a moment and then leaned over and kissed me on the lips.  My first real kiss, and it came from my sister!  She slipped her tongue out of her mouth and licked my lips.  "Is that what I taste like?" she asked.  I just nodded as she continued to lick at my face.  
In a couple of minutes, she had regained her composure.  My hand was resting on her hip, idly drawing circles on her skin.  Her hand went down to the front of my shorts and cupped my hard cock.  "Do you want me to make you come too?" Mary asked in a low voice.  "Yeah, " I replied, "but I want you to do something to me."  I then explained how I had seen Mom lick and suck on Dad's hard cock.  "Its just like I did to you," I explained.  Mary had a questioning look in her eye, so I continued.  "Do you remember the pictures I showed you?" referring to the porno pictures I has shown her a couple of weeks ago.  "The woman in those pictures had the guy's dick in her mouth," I said, as I built my case.  Mary still seemed reluctant, but I was pulling my pants and underwear down at the same time.  My hard on slapped back against my belly.  It seemed as if it were an inch longer than it had ever been before.  Mary's hand wrapped around my quivering rod, and she began to slowly stroke it up and down.  "You gotta at least try it." I pleaded with her.  
After a moment, she leaned her head down and stuck out her tongue.  She took a tentative lick at the bright red head.  I guess she decided that the taste was okay, because she began to lick at the head as if it were a lollipop.  A small drop of clear liquid appeared at the tiny slit.  Her tongue washed over it, licking it up.  A small string ran from her tongue back to the bulging head of my cock.  "Put the end of it in your mouth," I directed.  She opened her mouth as wide as she could and took the end into it.  "Watch your teeth!" I yelped, as they grated over the sensitive cockhead.  She pulled back, and wrapping her lips over her teeth, again slid the end of my throbbing cock into her mouth.  The sensation is one I remember to this day as she took another inch of my cock into her hot mouth.  I showed her how to rub the part that wasn't in her mouth, just the way Mom had done.  She started to suck on me as if I was a straw, lowering her head until she had about three inches of my cock in her mouth.  Her hand was gently cuddling my balls, tickling the few hairs that had grown on my sack.  It didn't take long before I felt that familiar feeling in my balls.  "I'm going to cum!" I hissed to Mary.  She must not have realized what I meant, as she continued to suck on my hard prick.  As the cum boiled up from my balls, she slipped most of my cock out of her mouth until just the head was in it.  Her small fingers propelled the sperm up cock and it splashed against the back of her throat.  She pulled away, just as a second spurt erupted from the slit and splashed against her cheek.  She continued to pump my hard-on, and another spurt landed on her chin.  Her small tongue reached out of her mouth and lapped up the thin white liquid before it rolled off her face.
Mary's fist moved up on my cock one last time.  A thick gob of white cream oozed out to the slit in it's bright red head.  Mary bent her head down and licked the up the last of my cum.  A small string of cum ran between her lips and the head of my cock.  She dropped her mouth to my now softening dick and washed the head of any remaining juices with her tongue and lips.  I reached down and wiped away a small splash of cum that was still on her cheek.  Mary looked up at me with a look in her brown eyes that I still remember.  I pulled her up to me and kissed her hard on the lips. Her tongue slipped into my mouth and I could taste my cum still on her lips.  We laid there and held each other for a few minutes, until a sudden crack of thunder announced that a storm was coming.  We slid back into our clothes and hurried down from the treehouse as Mom appeared at the back door and called for us to come inside.


Chapter Six

	Things progressed pretty rapidly after that day.  It was inevitable that Mary and I would soon take each other's virginity.  We had begun leaving the doors to our shared bathroom unlocked, and often when one or the other of us was taking a shower, the other would peek in.  Mary walked in on me about a week later as I was standing in front of the toilet taking a pee.  She immediately reached down and took my dick into her hand and began splashing my stream of urine around the bowl. I told her she had to shake off the last few drops, but more than three shakes was playing with it.  She slowly shook off the last golden drop of urine, and then stroked me to a hard-on.  As I stood there, she jacked me off, and soon drops of thick white cum joined the yellow liquid in the bowl.  
	We were totally at ease being naked around each other.  Most of the time when we were in our treehouse, our clothes were off (except for those shoes and socks!) and we were learning how to give each other orgasms.  
	About two weeks after the our first episode of oral sex, we were laying on the blankets.  We both had our shorts off.  Mary was slowly pulling on my erect cock while I ran I finger gently up and down her puffy slit.  I slid my finger down to the wet hole at the bottom of her slit and gently slid my finger inside of her.  I soon met the resistance of her still intact hymen.  I began to move my finger in and out, pressing against the thin piece of flesh.  As I pumped a little bit harder, my finger suddenly punched through the flimsy membrane.  Mary squealed and jumped back a little bit.  "That hurt!" she said, a slight quiver in her voice.  "I think I busted your hymen," I said, quoting the correct phrase from the book on marital sex that Mary had found at camp.  I gently put my finger back inside her sopping wet cunny and began to slide it in and out again.  Soon, my finger was buried deep inside her.  She began to moan quietly as I pumped my finger into her slick hole.  I moved my finger around inside her, eliciting even more moans from her.  She quickly reached an orgasm, and I  could feel her pussy muscles squeezing against my finger.  As I pulled my finger from her cunny, I could see a small bit of blood mixed in with her juices.  "Are you okay?" I asked.  "I think you did break it," she said quietly, "It's kinda sore."  We laid there for a little while longer before Mom called us to come in.  
	That night, after Mary and I had gone to bed, I laid awake reading for a while.  I heard Mom and Dad come up and go to bed.  In a few minutes, I heard that now familiar moan that I would lay awake to hear.  This time, I quickly slid through the bathroom into Mary's dark room.  She was laying on top of the covers, her pink nightgown pushed up around her hips.  I could see the white flesh of her bare cunny.  I put my hand over her mouth so she wouldn't make any noise.  Her eyes popped open in fright, but she calmed quickly when she saw it was me.  I motioned for her to be quite and to follow me.  We went back through my bedroom, and silently opened the door to the hallway.  As we crawled down the hallway, we could hear Mom's quite moan and the occasional slap of flesh on flesh.  As we looked in the open doorway, Mom was bouncing up and down on Dad's thick shaft.  Mary's eyes grew wide as she watched Dad's hard cock pound up into her hairy pussy.  Just as they had done before, they rolled over and Dad began to thrust deep into Mom's cunny.  He would almost pull all the way out before he would slam home another thrust.  He finally pushed himself as far as he could go into her and held it there.  Mom's legs had wrapped around his back, and she let out a loud moan as an orgasm swept through her body.  
	As they lay there kissing, Mary and I slipped back down the hall and into my room.  "Did you see the size of Dad's thing," Mary whispered, "It looked like it was a foot long."  Hearing Mom and Dad stirring, Mary hurried back into her room and jumped into bed.  I did the same thing.  About five minutes later, my door opened and Mom peeked in to see if I was asleep.  I played possum, trying to breath regularly.  "They're asleep," she said to Dad, who must have been looking into Mary's room.  
 The next day, Mary had to help Mom clean the house.  I had several chores to do around the yard at the same time.  After we finished lunch, I went back out and finished pulling weeds out of the flower beds.  After going inside and getting a drink, I headed for the treehouse.  I spread out the blankets and pillows, then pulled out the "fuck book" that we kept hidden in one of the pillow covers.  I was reading a part where one nurse offered to wash another nurse's hair.  They quickly began playing with each other's tits and pussies.  My dick was rock hard, so I got up on my knees and slid my shorts and underwear off.  As I began to stroke my hard-on, I heard Mary coming up the ladder.  She scrambled into the treehouse and looked at me laying there with my hard-on in my right hand.  "Starting without me?" she asked and she pulled her T-shirt over her head.  We were so comfortable being naked around each other that I didn't even miss a stroke.  She slid off her shorts and panties, then reached over and replaced my hand with hers.  After a half dozen strokes, she bent her head down and took my throbbing member into her mouth and began to suck on it.  I reached over and pulled her around until I could slide a finger into her already wet cunny.  
To my surprise, she shifted herself until she was straddling my head, her bald cunny right above my mouth.  "I read about this in the book," she said.  She lowered her hips until I could reach her with my tongue.  I began to lick at her bright pink lips, using my fingers to pull them open so I could find the small hole at the bottom.  I slid a finger deep into her wet hole and began to move it in and out.  At the same time, I started licking the small bump at the top of her slit.  Her clit grew and slowly appeared out from under it's protective hood.  Mary continued to bob up and down on my cock, her fingers gently stroking the part she could not get into her mouth.  We continued like this for two or three minutes before I felt the cum rising from my balls and exploding up my rock hard cock.  As soon as I started cumming, Mary ground her pussy into my face and clamped her thighs together as she began her own orgasm.  This was the first of many times that Mary and I would share the pleasure of cumming together.  
I turned around and laid down next to Mary, pulling her into my arms and kissing her gently on the lips.  She had pulled away from my erupting cock, and had streaks of my cum on her face and in her hair.  I tried to clean her face as best I could.  After laying naked for a few more minutes, Mary reached down and gently took my soft cock into her hand.  She had just started to stroke it when Mom called for us from the back door.  Since I still had a shirt on, I stuck my head up and yelled that we would be in a minute.  We hurriedly slid our clothes on, and after a quick kiss, headed for the back door.  Mom was waiting for us when we went into the kitchen,  as she was wanting to go to the grocery store.  "How do you kids get so dirty so fast?" she asked and she wet a finger and wiped a dirty streak from Mary's face.  We both realized that the streak was my cum, and prayed that Mom wouldn't figure it out.  She apparently had no idea, as she herded us into the car and off to the store.

Chapter Seven

The next week we left on our annual vacation.  This did not give Mary and I many chances to experiment with our newly found sexuality.  However, one night while we were on the road, Mom and Dad got two adjoining motel rooms instead of the normal one.  Mary, David and I were to stay in one room while Mom and Dad were in the other.  Mary and I quickly knew why this was happening.  Mary and I played in the motel pool for a while after dinner, while Mom played with David in the kiddy pool.  We went back to the rooms and watched TV until about 10:00 when Dad told us it was time to go to bed.  We went into the other room where David was already asleep in his crib.  "You two be quite so you don't wake up your little brother," Mom said after we had changed into our PJ's and crawled into our separate beds.  As she left, she left the door between the two rooms cracked open.  
Mary soon fell asleep, but I was too excited.  After about an hour, Dad peeked into the room to see if we were asleep.  He pushed the door closed, but I did not hear it latch.  I waited for about five minutes, then quietly got up and slipped over to the door.  I very gently pushed it open about two inches.  Mom and Dad were laying on the king sized bed kissing.  Dad's hand was rubbing her breasts through her nightgown.  In a moment, Mom raised up and pulled the nightgown over her head, revealing her small breasts.  Her huge nipples were already erect as Dad began to suck and play with them.  I watched for several minutes as they kissed and played with each other.  After about five minutes, Dad slipped down and began to lick Mom's hairy cunny.  After a few licks, Mom pulled him around and began to kiss and lick his swollen dick, the same way Mary and I had done the week before.  
As I concentrated on what Mom and Dad were doing, I suddenly felt a presence behind me.  I turned to see Mary behind me looking through the crack in the door just as I was.  We smiled at each other and turned back to watch.  After a couple more minutes of mutual sucking, Dad disengaged his hard cock from her mouth and rolled her over onto her stomach.  Mom got up on all-fours as Dad moved around behind her.  As we watched, he pulled her butt cheeks apart and gently started to slip his cock into her hairy cunt.  He began fucking her in earnest, his groin slapping against her ass.  I felt Mary moving behind me, and when I glanced around I saw that she had her hand down her panties and was rubbing her cunny.  My own dick was rock hard, and had slipped out of the fly of my PJ's.  
A couple of minutes later, Dad began to moan as his tempo picked up.  He was slamming into Mom now, her butt smacking at each thrust.  His hands had reached down and he had a breast in each hand, squeezing them as he slammed home one last time and let out a loud moan.  Mom kind of collapsed forward on the bed, her legs tightly pulled together holding Dad inside her. I reached up and gently closed the door, and Mary and I slipped back into our beds.  About ten minutes later, Mom came in to check on the baby.  Mary and I both played possum so she would think we were asleep.  When she went back into the other room, she left the door open again.  
I was so horny my cock was hard as steel.  After the lights were turned off in the other room, I waited for a few minutes, then slowly began to stroke my cock.  I looked over and Mary was silently watching me, her own hand rubbing furiously on her swollen slit.  We watched each other masturbate until I saw Mary bite her lip as she began to cum.  At the same time, my cock began to spit large white pearls of cum onto my chest.  One of them almost reached my shoulder.  Mary slipped out of her bed and quietly came over to mine.  She bent over me and began to lick the cum off of my chest.   I slid my hand between her legs and gently felt her soaked cunny.  She cleaned all the cum off of my stomach, then gently washed the head of my cock with her tongue.   After licking the last bit off of my shoulder, she kissed me on the lips.  I could taste my cum on her lips as our tongues battled briefly.  
The next afternoon, we arrived at our Grandmother's house.  Our grandmother lived with her sister, a spinster who had never married, and a little poodle.  My grandfather had died when my Dad was in college.  Grandma lived in a small three bedroom house in an old city neighborhood.  Because Mom and Dad would take the remaining bedroom with David's crib, Mary and I were to sleep in the basement on an old double bed that was stored there.  I liked the basement, because it seemed to be the only cool place in Grandma's un-air-conditioned house.  The bed was really an old thick, soft mattress on a wooden platform that didn't have any springs.
That night, as we were getting ready for bed, I heard Grandma make the comment to my Mom that pretty soon Mary and I would not be able to sleep in the same bed.  Mom replied that she hoped she would not have to worry about that for at least a couple more years.  Little did she know!!!  There was only one bathroom in the house, so we took turns getting ready for bed.  I took a shower and put on my PJ's.  Mary then took a bath as Dad and I watched the end of a baseball game.  Mary came out of the bathroom in her nightgown, with a towel wrapped around her wet hair.  It was a hot night, and the humidity made the gown cling to her tiny breasts.  
As soon as the ballgame was over, everybody headed for bed.  Mom told Mary and I to go straight to bed and not to mess around with anything in the basement.  Grandma went down to the basement with us to make sure everything was OK.  As Mary and I crawled into opposite sides of the bed, Grandma told us to stay on our own sides of the bed and not to fight over the covers.  She said she would leave a light on in the kitchen in case we needed to get up and go to the bathroom.  She went back upstairs, turning the lights out as she went.  Mary and I laid there for a few minutes talking when we heard a noise on the stairs.  Mom came halfway down the stairs to check on us.  We were on far opposite sides of the bed, and Mary had stuck a pillow in between us.  She told us to go on to sleep and went back upstairs.  As she reached the top of the stairs, Mary called to her and asked if she would close the door so the dog could not come down.  Mom knew that Mary was scared of the little dog, so she closed the door.  The basement was now softly lit by the light of a streetlight coming through the window above the bed.
Mary and I talked quietly for a little while, until we didn't hear any more movement upstairs.  "I think everybody's asleep now," she said.  We both rolled toward the middle of the bed, throwing the pillow out of the way.  I rolled over somewhat on top of Mary, and kissed her softly on the lips.  She slipped her tongue between my lips.  My hand slipped up and began to massage her small breast mounds.  Her nipples immediately began to swell and harden.  Her hand went straight to my crotch, where she found my cock already rock hard.  She slipped her hand through the fly of my PJ's and began to stroke me.  We broke our kiss and Mary sat up as I pulled her nightgown over her head.  She returned the favor, pulling my pajama top over my head.  I raised my butt up off the bed and she helped me slide my bottoms off.  My hard-on got caught in the fly, then slapped back against my belly.  
We fell back into an embrace, again kissing and swapping tongues.  Her hand went back to my hard cock.  I broke off the kiss and moved down to where I could take a hard nipple into my mouth.  My hand slipped up her thigh and into the moist vee of her crotch.  My fingers parted her pussy lips, which were already soaking wet.  I slid one finger into her wet hole, and began to massage her bump with my thumb.  I began to finger fuck her sopping cunny.  She let go of my cock and pulled me tight against her.  I switched nipples, now sucking and pulling at the other one.  
"Now," she said as she pulled my face back up to hers.  As I pulled her close to me, her mouth met mine in a deep kiss.  She opened her thighs as my hard-on slipped up to nestle itself in her wet slit.  I slowly began to slip inside her.  As I went in, I met some resistance.  I learned that by pulling back slightly and moving in again, her juices would spread deeper into her hole.  After about five or six of these in and out movements, I was buried to the hilt into her tight, hot, virgin cunny!  The sensation was far greater than her hand or even her mouth around my swollen dick.  The velvety smoothness and heat were fantastic.  I slowly started to pull out, remembering what I had seen Dad do with Mom. 
I was fucking my little sister!  I rolled over on top of her and began to move in and out as I had seen Dad do.  Unfortunately, the sensation was so great that I probably didn't go more than a dozen strokes before I felt the cum exploding from my balls and spewing into her hot hole.  The orgasm was by far the most intense I had ever had.  Mary had wrapped her legs around my back and was holding me in her as deep as she could.  I collapsed on top of her, our lips again meeting in a deep kiss.  My cock slowly deflated, and finally slipped out of her pussy.  Our combined juices spilled from her pussy.  Luckily, we had somehow rolled over onto the towel that she had been wearing around her hair, so the sheets weren't stained too badly.  
As we lay there, I slipped my hand down to her wet pussy.  I began to massage her bump again, using the juices as a lubricant.  Within a minute, she arched her back as an orgasm swept through her body.  During this whole time, neither one of us had spoken more than one or two words.  We pulled each other close, and held each other for quite a while.  After a little while we fell asleep in each other's arms.  
I awoke sometime later to the feel of a soft warm mouth enveloping my cock.  I looked down to see Mary's blond head in my lap, and her soft hand wrapping around my stiffening dick.  I put my hand on the back of her head and stroked her hair.  She looked up and smiled at me.  My dick was now rock hard.  She kissed the purple head, then crawled up and threw her leg over mine.  As she straddled my hips, I reached over and pulled the cum stained towel underneath my butt.  Mary reached down and pried my hard-on away from my belly, positioning the head at the entrance to her swollen cunny.  She slowly slid down the length of it until her soft lips were resting on my sparse pubic hair.  My hands slid down under her soft butt, and with my help, she began to raise and lower herself.  My hips bucked up against her as we began to fuck in earnest.  She lowered herself down until I was buried deep in her, then began to move back and forth, rubbing her bump against me.  This time it was Mary who then began to hump quickly up and down as an orgasm began to spill through her tiny body.  I could feel the jism rise up and explode against the top of her tight pussy as she impaled herself as far as she could on my cock.  She collapsed on top of me this time, my dick still buried in her tight, wet pussy.  "I love you," she said, as she laid her head on my shoulder.  "I love you, too," I said.  
These were the only words that passed between us as we slowly disengaged from each other.  After a few minutes, we got up and turned on the light near the bed.  A small wet patch was visible on the sheets, but most of our juices had been caught by the towel.   We used the towel to wipe the rest of the evidence of our lovemaking from our bodies, then Mary took the towel over to a basket of clothes near the washing machine and buried it deep in the basket.  She pulled out another towel which looked the same and carried it back to the bed.  "I hope nobody notices," she said.  We slowly put our nightclothes back on and crawled back into the bed.
The next morning, Grandma came down the stairs to wake us up.  Mary had rolled over close to me, and thrown her arm over me.  Fortunately, she was under the covers, and I was on top of them, so we must have looked fairly innocent.  "Did you sleep okay?" Grandma asked.  If she only knew!


*******  *******  *******
That was our first time, but there would be many, many more to come.  Mary and I shared a deep love and lust that lasts even now.  After that first time, we would make love whenever we found the chance.  The doors between our shared bathroom seldom stayed closed, and many nights we would meet in there to make love as our parents slept.  One time Mom even came into Mary's room to put away clothes as we were in the bathroom, Mary bent over the vanity with my boner deep in her from behind.  Luckily, we did close the door once we were in there together.  
About two years after we first made love in our Grandmother's basement, Mary began her periods.  Mom sat her down and explained the facts of life to her.  We had to resort to oral sex for a while until I found a gas station near our house that had a rubber machine in the men's room.  It was also during this time that we discovered the joys of anal sex.  
Many of the memorable moments of our lives involved Mary and I.  When she had a fight with her boyfriend on prom night, it was I that made love to her that night.  On my high school graduation night, Mary was the girl in the back seat with me, making love overlooking the lake.  We were never jealous of other lovers that each other would take.  The only other person who ever knew about us was our cousin Kimmy, who joined us in our lovemaking when I was sixteen.  But that is another story........
