It all started on that Sunday morning. I woke a little early and head the sound of my sister in the shower. I wated till I heard the door close before I made my move. She was a 3 yrs younger than I and my friends seems to always say how hot she was. Today I thought I'd take a look for myself. I got out of bed and headed towards the shower. It was unde repairs, so the main wall was just a blanket held up by nails.

There was a small rip in the blanket that I peered through. Itwasn't very god but I could see her naked siluette. My heart was pounding as I watched the show. Soon enoughI she stepped into the shower. I stood there for some time as I listend and pondered what to do. After a few minutes she stepped out and my eye went to that small rip.

This wasn't good enough. I had to see more. I slowly gripped the door knoib, watching her shadow as I did so. It was now or never. I opened the door and started to walk in. I saw her fully nude then. She was a beauty. Her body was still glistening from the water. As she saw me I swore to make it look like an accident then quickliy backed up a few paces. She imeddiately squated and let out a low scream. I wasn't the only one in the house so I got worried. Then the opposite thing happened, a wet arm pulled me in and closed the door. Now here I was, her standing dripping naked and me in my boxers.

"What do you think your doing? she demanded, planting her hands on her hips. It was almost sexy.

"I didn't hear the water, sorry" I replied in the calmest tome I could think of.

"I know about all your secrets..." She said in a sly voice. "if ypur friends were to find out, you may be in a lot of trouble..." she trailed off.

I was really worried here. All this time I thought I had the edge, I was only being set up.

"Now that You've seen me naked, i think you should be too, you saw me, I see you"

She had all the cards, I had to obey. I took off my boxers. and tossed them aside. Now I was standing face to face with my naked sister.

"Do you like what you see? she asked in a low seductive voice. I just stoof there while she modeled for me.

"While were both naked and horny why don't we just all our sexual frustration out of us. I know You've been spying on me for some time"

She then grabbed my hands and firmly placed them on her breasts.

"You like these don't you..." She looked down at my raging hardon.

"We shouldn't be doing this..." She then covered my lips and grabbed cock and started to move her hands.

"You started this, now you can't finish?"

" you could get..." with that she shoved me onto my back and stood over me. "Here's the deal, you just lie there and let me do all the work..."

She moved lowered herself, and placed the head my cock at the lips of her vagina.

"we're gonna do this or I spill the beans"

She lowerd herself fully onto my swollen cock and just sat sat there with a smile on her face there was a knock on the door...I got scared. If someone came in and saw my own sister straddling me I would be a dead.

"Everything ok, ? some one aksed.

"It's fine be out in a few my sister answered She looked back down on me with an evil grin and moved her hips once. A shot of pleasure shot thorugh me

"The fun is sjust beginning..." She put my hands on her breats again and started to ride me at a constant pace. The pleasure was almost too much I could barely manage to control myself. I realize we weren't using protection and tried to get her off me. She just move faster with very jerk.

"You don't want to be doing that...I'm not on the pill and very fertile.." she slowed down.

"Is this what you wanted?" she asked, riding me a little faster. I was too busy fighting my pending ejaculation. she seemed to be smiling.

"bet you can't hold out much longer", she was milking my cock more with her pussy.

i was getting close. I desperately tried to think of a way to get out. If I tried anything she's just increase her pace.

"I can feel it now..." she said as she grabbed my balls and squeezed.

"just let it out..." she leaned forward and pressed her breats into my face. I tried to fight it off, but I was no mach. I closed my eyes as I felt my sperm leave my body and get sucked up into her fertile womb.

Satisfied, she kissed my lips as she climbed off me, using a towel to hold my potent incest sperm insider her baby box.

"That was fun wasn't it? she said as he looked in the mirror. "Now if you say any thing this..."
Horrified on the floor, all I could do was stare.

"see you in 9 months.." with that she left, still holding my baby jiuce in her womb. Even now I could imagine my seed fertilizing her egg and making a child swell in her belly.

"what have I done..." I sighed as I looked at my still erect penis.
