Amethyst sent me an email explaining that she is a university student that finds my stories erotic and that she dreams of having a penis of her own to poke and prod the guys as the fancy strikes her. I fully understand that on the internet people can misrepresent who they are, but I choose to believe her. Please suspend your disbelief and enjoy her fantasy with me. * I stand and look at myself in the mirror. To my eyes I appear to be just an average every day female university student. I have on a pair of blue lacy panties with a matching bra and my mahogany hair is pulled back in a blue ribbon. Hazel eyes stare back at me from a fair complexion as smooth as a bowl of cream. I have pouty, full pink lips that look as though I'm wearing lipstick, even though I'm not. I'm five feet and seven inches tall and curvaceous in all the right places. Some guys have called me beautiful. I'm not so sure of all that, but I do think I'm pretty. On the table beside me is a white sports sock that is formed into a long thick roll. I pick it up and roll it slowly back and forth between my hands before I pull out the front of my panties and push it down inside. I look at it in the mirror and realize it's not quite in the right spot so I adjust it down further. I twist slightly side to side and to me it looks real, like I have an actual penis. I gently run my fingers along the length of it. I'm breathing harder and my nipples are showing through the bra. I imagine that my fingers are gliding over thin fabric that is separating them from the skin of my penis. It feels good and makes me grow bigger, harder, swelling to stretch the fabric of my panties. I place my other hand on my breast to play with my nipple as I rub my growing cock. Closing my eyes I can see Devin, the captain of the university's polo team, bent over a saddle stored on a saw horse. The skin tight riding breeches conform to his perfectly shaped arse as if he has been dipped in them. I step up behind him and caress his butt, the fabric makes it feel smooth and slick. After a few seconds I step closer and press my penis into the crease of his cheeks and begin to grind my throbbing member against him. He moans with anticipation of the pleasure to come. My breath is coming quicker as I press harder and harder. I spread my legs so I can press deeper into the cleft of his butt. I'm so excited that I know it won't be long till I cum. I pinch my nipple and squeeze my breast as I'm panting in ecstasy, humping his arse crack hard in the last moments before warmth spreads through my crotch. I open my eyes and the fantasy fades leaving behind the warm glow of the wonderful orgasm I've just had to start my day. I strip off my bra and panties, toss my penis in the dirty laundry basket and jump in the shower. Thirty minutes later I'm on my way across campus toward the chemistry building. I have on a cute purple tee that fits close to my body and is cut low enough to show some cleavage. I want to attract some attention, just not too much attention. A flirty little white and purple skirt bounces just above my knee in the warm fall sunshine. There are many other students out and about on their way to classes. Some I recognize, most I don't. I'm sure that none of them could imagine that I'd started my day by dreaming about having a penis and rubbing it against the captain of the polo team's tight arse. If I hadn't been in such a hurry to get to the Lab I'd have done a lot more than just rub it against him. But it's okay, I'll save that for later tonight. This brings a smile to my face which catches the eye of a passing young man who smiles back at me. We pass without speaking and I sneak a quick peek back at his bum. It looks pretty good in his skinny jeans and I think of how nice it would be to push my cock between those butt cheeks and stir around till I shoot a huge load in him. He takes a look back over his shoulder and busts me checking him out. He grins broadly and I return his grin, though I'd bet he wouldn't be grinning if he could read my mind! The chemistry lab is on the third floor. I take the stairs and at the top I'm barely breathing hard. I go into the lab itself and look around for the student I'm supposed to tutor. "Caroline! Are you in here?" "Coming!" Caroline comes out of one of the supply rooms carrying a rather large load of supplies. Some various glass wares, containers with chemicals and a rather precariously placed Bunsen burner. "Do you need a hand?" "Oh that would be wonderful! Could you take the Bunsen? It feels as though I'm about to drop it." I move to help her with the burner, but just before I get there it slips off her stack of supplies and drops onto a workbench. I lunge to grab it too late and with a clatter it slides into a beaker full of a bluish liquid. I try to catch them both and end up spilling the beaker all down my front, soaking me to the skin. "Oh Amethyst! I'm so sorry! Are you Okay?" I brush at my wet clothes as I set the now empty beaker back on the workbench. "Yes I'm fine." Caroline puts her load down on a nearby bench and hurries over to me. Picking up the empty beaker she wafts her hand over it and sniffs. "Well I don't smell anything toxic, but just to be safe we have to get you out of those clothes." "If you were a guy I would suspect that you're up to something!" Caroline blushes and says, "Oh no! You just can't take any chances with chemicals. Come with me." She takes me back to the supply room and pulls a ratty old pair of coveralls from a hook and hands them to me. "Here, take off all of your clothes and put these on. Then go straight home and take a shower!" I hold the coveralls up in front of me as if they are the decaying remains of a dead animal. "You can't be serious. I can't have anyone see me in...in...this...thing!" "Well you can't walk back to your dorm room naked!" "I'd rather be seen naked than in this nasty old rag." Caroline takes a deep breath and then through clenched teeth simply says, "Do it." and walks from the room. Reluctantly I strip down. My shirt, skirt and bra go in a pile on the floor and I have my thumbs hooked in the waistband of my panties when I stop. I can't bear the thought of having nothing between me and those coveralls. I gather up my courage and begin to don the musty garment. As it brushes against me I get goose bumps and my skin is crawling. I grab my pile of clothes and head out the door. "I'm so sorry this has happened Amethyst. I should never have suggested you tutor me here in the lab. Now don't forget to wash very thoroughly! I'll stop by later to see you and if you start feeling bad get to a hospital!" Caroline says that last at my back because I'm heading out the door and down the stairs. At the first landing I stop to roll up the pants legs on the coveralls so I don't trip on my way down. I'm walking quickly as I leave the chemistry building and head out toward my dorm. I'm about a quarter of the way there when I begin to feel a burning sensation where the chemical has made my panties wet. I walk faster. I'm sweating from my exertions now and the burning feeling begins to worsen. I start to jog, oblivious to the other people on the green. With each passing second the burning gets worse. It's getting so intense I'm on the verge of stripping naked, but I only have a couple of minutes till I get to my room. I bound up the stairs two at a time, unzipping the coveralls as I'm going through the door. They drop in a pile as I scramble for the shower. I get in and turn it on full bore, shedding my panties in the cold water I start scrubbing at my burning nether regions. Within seconds the burning subsides and I slump to the floor of the shower in tears. When I can no longer stand the cold water I drag myself out of the shower and pat dry with a towel. I get up on the bed and lay back on the pillows spreading my legs to allow my 'down there' to air dry. The lips are red and puffy, but that seems to be all and it doesn't hurt anymore, which is good. I feel so tired maybe I'll just take a quick nap and then I'll decide if I need to go to the hospital. I close my eyes and immediately drift off. Diffused late afternoon light coming through the small dorm room window wakes me. I'm still naked on my bed so I grab the spread and roll away from the light intending to sleep some more, but as soon as I do I feel something warm and heavy flop onto my thigh and slide off onto the bed. With a start I sit up and look at my crotch. I can't help gasping in amazement because there between my legs is a penis. Not just any penis, but a rather large one and directly beneath it is a matching ball sac. I stare in disbelief and it takes me a full thirty seconds to get up the nerve to touch it. Not because I'm afraid of it, but because I'm afraid I'll wake up and it will all be a dream. As my fingers trace lightly along its smooth length I can feel that I'm touching my own skin. My heart is pounding in my chest and I'm trembling with excitement. The penis begins to respond to my touch. Growing as I watch, it lengthens and swells. I'm fascinated as I watch it grow, having never watched one go from flaccid to hard before I find it completely engrossing. In short order it is standing straight up from my crotch, throbbing and twitching with my heartbeat. I marvel at how smooth and feminine it looks. I've seen penises in porn movies and they always seem to look so bumpy with veins and stuff, nothing like mine. I take it in my hand and my fingers won't touch around it. It feels heavy and purposeful. A small squeeze sends shivers of pleasure coursing through me and pulls a moan from my lips. I move my hand up and down the length of it, slowly, feeling how hard it is and how good it feels to have it rubbed. I have lube in the drawer by the bed and in quick order I place some of it in the palm of my hand. The lube allows me to grip it harder. I'm squeezing it now, stroking it from base to tip. Everything I do seems to make it feel better and the good feeling just keeps growing and growing until like a car accelerating uphill toward a cliff I explode over the edge. It goes off with a huge contraction of my kegel muscles, and the first shot clears the end of the bed, with the next three drawing a line across the bed back to me. As quickly as the energy was building, suddenly it's all gone and I feel as spent as if I just dashed up several flights of stairs. I'm still breathing hard and my body is tingling. I let go of my penis and it begins to soften. First it droops over onto my leg then it slowly continues to shrink a little more, but it doesn't become fully flaccid. I let out a little sigh of relief, glad that it looks like it's not going away. I can't take my eyes off of it. I've seen other penises, I'm no prude, but mine is beautiful. Mine is smooth as if it is chiseled from marble. The foreskin is super soft and sensitive. I pull it back to reveal the head and it glistens with some of my cum. Pulling back the foreskin has an immediate impact on it and it begins to grow again. Within a few seconds it's standing straight and hard. I slide off the bed and it bobs around as I go to the full length mirror. The view in the mirror makes it looks even bigger and I can't think of a single guy I've seen or touched that is larger than I am now. I'm grinning like a maniac as I take in how incredible it looks on my body, even better than I'd ever dreamed one could look. At a glance I appear to be like one of those shemales on the internet, but better. I'm a woman with a penis, not a man trying to look like a woman. Suddenly I have a pang of empathy for them because they have to work so hard to be women. The difference with me is that I don't want to be a man, I just want to be a girl with a penis. I think I look perfect now. I'm startled from my revere by a knocking at my door. I hear Caroline's muffled voice as she calls out. "Amethyst? Are you in there?" "Yea, I'm here. Everything's fine! Thanks for checking on me!" "I'm glad to hear it! Can I come in and see you?" I look down at my new penis and tell her, "Sorry, I'm not dressed at the moment. Could we talk later?" "Amethyst, I'm a girl. I've seen everything you've got. What's the big deal? Throw on a robe and open the door please." I roll my eyes and grab my robe off of the chair in the bedroom and pull it on as I head into the common room. Unfortunately, my new penis appears to be curious about who's at the door and proceeds to stick out the front of the robe. I tuck it back in, but to no avail. It pops right back out. "Amethyst?" "I'm coming Caroline. Just a moment!" I have to tuck it in and hold the front shut as I shuffle over to the door. I open it and tell her, "Thanks for coming to check on me Caroline, it's very sweet of you, but I'd really like to be alone right now." "I understand, but you can never be too careful when it comes to a chemical spill. Have you been feeling ok? Has there been any changes in your...you know...girl parts? Blisters or redness?" "Well...I uh...things are fine. Really they are Caroline, thanks again..." Caroline tries to push in through the partially open door, but I hold it easily. It's almost as if I'm stronger now. "Amethyst, please let me in." While I'm thinking about my new strength Caroline catches me off guard with a big push. I stumble backward to land on my butt on the floor. My robe opens up and my new penis bobs hello to Caroline who covers her mouth with her hands and gasps as if she's a heroine in some old B horror movie. I make no attempt to cover up. What's the use? "Oh Amethyst! I'm so sorry this has happened to you! Come with me and we'll go to the hospital straight away."She reaches for my hand but I pull back. "No. I'm not going to the hospital." "But we have to get that thing removed! You can't have babies and think of how hard that will be to explain to your boyfriend!" "I said no." "But I don't understand...why would you..." "Because I like it and I've always wanted one." Caroline looks at me as if I've just told her that I like to swallow small bunnies alive. "You can't be serious." "I'm very serious." I pull my legs under me and stand up. My penis is standing out straight from my body and I still make no attempt to cover it. Caroline gets this funny look on her face and suddenly drops to her knees to take my turgid dick in her mouth. I start to pull away and could have before she touched me, but something makes me let her to take me. I pull my robe out of the way and hold it in place by resting my hands on my hips. "Caroline, I don't think this is a good idea." But I'm not trying very hard to stop her. Her hot wet mouth feels a million times better than my hand. Caroline is a skinny girl with mousy brown hair. She wears black square rimmed glasses that give her a modern geeky appearance. Her breasts are small and her figure in general is rather straight. As far as I know she doesn't have a boyfriend or even date much. I'm not attracted to her in the least, however her mouth is brilliant! She keeps making slurping and sucking sounds as she works to get half of me in her mouth. I'm standing there looking down at the girl on her knees servicing me and I feel a little rush of power. I watch her mouth slide back and forth along my shaft while she grips the base with both hands. She's sucking and moaning like she's going to orgasm soon and the more animated she becomes the more excited I get. One of her hands disappears to her own crotch and she redoubles her efforts as she works me over. Finally I can't stand it anymore. I reach out for her head and hold it in my hands as I make some hard thrusts into her mouth. Now both of her hands are working on her own body. With a huge grunt the waves of pleasure explode over me and I begin to cum hard. As I'm punishing her mouth she groans and makes some whimpering sounds that tell me she's having an orgasm of her own. This orgasm is much more intense for me and my head is spinning as I release her. She stays on her knees breathing hard. With my orgasm finished it's as if I've suddenly had cold water dumped on me and now I'm keenly aware that I want to be anywhere but here. I step back from Caroline and pull my robe closed. The situation is so awkward I have no idea what to say to her. She appears to be feeling the same. "Caroline, I...uh...need to go to class. Yep, class, that's what I need to do. Um...thanks?" "Amethyst, I'm so sorry. I don't know what came over me. One second I'm standing there trying to talk you into having it removed and the next I'm on my knees like some slut sucking you like my life depends on it! I'm so ashamed!" "Oh,...don't worry about it. If it helps any it did feel really good. But like I say, I've got to get to class...and...uh...you need to leave." I reach down and easily pull her up from the floor. Again I'm struck by how strong I am. I could easily swing her into my arms and carry her off to bed. Bed? What the hell am I thinking? I wipe some of my cum from the corner of her mouth with my robe as I tell her, "Now don't worry about a thing. It's going to be fine and tomorrow we'll meet so that we can get that tutoring session in before your test. I'll call you tomorrow morning. Thanks again for stopping by." I finish hustling her out the door and get it closed before she can say anything further. I heave a big sigh and head to my bathroom to get ready for class. When I get to the bathroom I notice my pretend penis from this morning lying in the dirty clothes basket. I pick it out and place it along side my real penis. I can see that I was thinking way too small since the flesh one is limp and still as big as the pretend one. My mind wanders back to this morning's little fantasy interlude and I suddenly realize that it doesn't have to be a fantasy anymore. My balls tingle and my prick begins to expand simply at the thought of rubbing along the polo captain's round arse. I turn my mind to class in an attempt to keep from getting any bigger and it distracts me just enough. Another flirty skirt and a purple camisole with a white vee neck cashmere sweater over it later and I'm ready to head out to class. There is a problem though. My new package barely fits in my girl panties and I have to keep adjusting it to keep my balls from popping out. I grab my books and just before I head out the door I say to the empty room. "Watch out world! Amethyst has a brand new cock and she's dying to use it!" I laugh at my own corny joke and head to class. On my way the world has a much different look. Not the buildings and trees, but the people. The guys, to be specific. I'm looking at every guy's butt and noticing how it's shaped. Some are round, some are flat, some are narrow and my penis wants to try them all on for size. I'm actually giddy with the prospect that I'm now fully equipped to make love to them all in ways they've most likely never considered. There is a ruckus behind me and I look over my shoulder and see two young guys wrestling in the grass, but they are laughing so I keep walking. Before I can turn back I bump into a young man that has bent over in front of me to tie his shoe. My penis makes perfect contact with his upturned arse and sends shivers up my spine as I grab his hips to steady him and keep him from falling over. I'm holding him in such a position that if we were naked I'd be buried in his delicious bottom. I can't help pressing against him harder as my cock begins to swell. "Hey now! We'll have none of that out here on the green! We don't want anyone to get the wrong idea!" He steps away from me blushing a bright red over his pale jaw line. "Whoops! I was looking over my shoulder when I bumped into you and I was just trying to keep from knocking you over." He glanced down at the front of my skirt and seeing the slight bulge there he laughed nervously and said in a low voice. Amethyst: The Girl with a Penis "Looks like you were having plans of knocking me up while you kept from knocking me over." Now it's my turn to blush. I don't know what to say so he tips me a wink and says, "Its ok, I'll keep your secret. I'm an open minded sort of guy. As a matter of fact I'm so open minded that I'd like to buy you the caffeinated beverage of your choice if you're willing to accompany me to the commissary." I look at him in a complete loss of words. "Maybe we should try this from a different angle, my name's Nathan. Not Nate or Nat or anything else. Just Nathan. And you would be?" "I'm Amethyst. "Amethyst." He says it like he's tasting it. "I like that. Very pretty. Much like the owner. So Amethyst, will you accompany me so we can get to know one another better and enjoy a frosty beverage?" "I want to, really, but I've got class in a few minutes and I can't miss class." He glances down at the front of my skirt where the bulge is a little bigger now. He looks at me with strikingly blue eyes that peek out from under the black hair hanging across his forehead and says, "I can see that you're interested in me and I'm telling you that I'm interested in you. I take my studies seriously and would never advocate for skipping class, however, just this once won't kill our GPAs will it?" I'm so confused. I know I should go to class, but the thought of maybe getting in Nathan's pants is causing my penis to stiffen and my resolve to weaken. "I promise that we will do more than talk if that's what's holding you back." Resolve? What resolve? My heart is pounding in my chest as look into those blue eyes and softly say, "Sure, I'll go with you." "Good. Now carry my postman's pouch so that it hides your excitement and we'll go get us a Coke or something." He slips his pouch over my head and we position it just so and then he offers me his hand. I take it and we walk hand and hand to the student union. Ten minutes later we are sipping on Cokes in a quiet corner. Nathan has told me all about his future plans to conquer the business world. He sounds very driven and I can tell that he is very smart. He asks about me and I tell him I'm studying banking and statistics. He nods sagely and suggests that one day perhaps we could collaborate on his empire building. We sit in silence for a bit and I finally get up enough nerve to ask, "So how did you get to be so 'open minded'?" "Well, a pal of mine back home and I were wondering what all the fuss was about homosexuality. We talked about it on and off at different times then out of the blue one day he kisses me. It wasn't wholly unpleasant so I went along. That night we went all the way. I screwed him. He screwed me. We both came several times and when it was over I'd learned that I really have no interest in men. None. But even though I didn't much care for buggering him, I found that I did like to be filled in the backside area. At least I enjoy that sensation as long as I don't have to look at a guy doing it to me. I had a girlfriend at the time and with some exceptional sweet talking I convinced her to use a strapon on me. She couldn't get into that scene so we only did it a couple of times. Not too long afterwards we broke up and I came to the university. There, you now know all of my sordid sexual details. So how about you? How long have you been living as a girl?" "All my life." "I know that people like you believe you are born as girls trapped in a boy's body and all, but how long have you looked like this?" "That's what I'm trying to say. I've always been a girl. I just got my penis this morning." Nathan looks at me with complete disbelief. "Really! It was a fortunate lab accident. I was going to the lab to tutor someone and wound up spilling a beaker full of some kind of blue liquid down my front." "Don't you mean unfortunate lab accident?" "Not for me. I've always wanted to have a penis. This is more of a dream come true. And to top it all off now I've met you." Nathan smiled. "You sound like a girl who plans to get lucky." My heart is pounding as I ask, "Well, aren't I?" Nathan opens the door to his apartment and flicks on a light as he leads me inside. I'm not sure what to expect, but what I see surprises me. His place is neat and tidy, conservatively furnished and pretty well matched up for a university student. It's a small one bedroom affair with a little galley kitchen off of the living area. I'm shaking with excitement and not noticing much else. He tosses his keys on the coffee table and turns to me. I reach for him and pull him into a kiss. Our lips meet for a moment and then I'm pressing my tongue into his mouth. I feel on the ragged edge of control, breathing hard through my nose. My hands are running up along his ribs and I can feel his muscles beneath his shirt. He is lean and hard, just like the penis straining to escape my panties. He pulls back breaking the kiss and I pull him back to me, but before I cover his mouth he sputters out, "Shouldn't we take it a little slower?" "No." And my hand is on the back of his neck pulling his mouth back to mine. I'm playing with his nipple through his shirt. Pinching it and rolling it between my finger and thumb which draws funny noises from the back of his throat. I slip a hand down onto his butt and feel his muscle tighten. He has a nice ass and I grip it hard in my hand. His arms are around my waist so I take one of his hands and place it on my cock. He squeezes it and my knees go weak. Then he runs his hand along the length. Not once but several times as if to be sure of what he's feeling. He pulls away from my mouth. "That thing is huge! There's no way I can handle that!" Feeling a bit desperate I say, "Sure you can! It's not that big, I'm sure it will fit in you just fine." "No, no I don't think so." He pulls back from me and we look at it together. Somehow it got out of my panties and it's sticking out from under the front of my skirt. In my head I have to admit he's right, it does look big. "I bet it's no bigger than yours!" I reach out and undo his pants. When I push them to the floor his under pants go with them and his penis pops out. There are a couple of inches separating them, but there is no need of a ruler. Mine is obviously larger. "Well now, isn't this embarrassing. At least when my friend and I compared them mine was a little bigger than his." I don't know what to say. In truth I wouldn't want it in my bottom either, but I very desperately want it inside of his. I feel like the moment is slipping away so I do the only thing I know to do. I take charge. "Listen Nathan, I didn't come here with you for some cheerful conversation. I came here to have sex with you. It only takes one look at my cock to tell how excited I am. So you and I are going to fuck. Now get on your knees and start sucking me." Nathan got a strange look in his eyes and just when I'm about to give up he drops to his knees, grips the base of my penis and takes the head in his mouth. It feels wonderful. So hot, so wet and slippery, so deliciously dirty that I want to come in his mouth right now. "Deeper. Take more of me in your mouth." And he does! Oh how incredible it feels! "That's it. Just a bit deeper. C'mon, you can do it." The tip of my cock reaches the back of his throat and he gags a little. He pulls back, swallows and goes down again. I'm looking down past my boobs to where my skirt is bunched up between his hands and my belly. I find the view of the round O of his lips sliding along my hard shaft mesmerizing and I know I'm only going to last a few more seconds. "Nathan, I'm going to cum and I want you to swallow it. Every drop." He looks up into my eyes and I see that he isn't very happy about that order, but he doesn't protest. I keep looking into his eyes as I get closer and closer. Finally the orgasm arrives like a freight train to a station it has no intention of stopping in. "MMM...Ugh...Ugh...UGH!" I flex my muscles, squirting the first hard shot into his throat. "UGH!" The next one is hot on the heels of the first and three more follow. The whole time I'm watching the look on his face. He grimaces, but swallows like a good boy. Unlike having Caroline suck me off this time it revs me up for the main event. I'm finally going to get to push my very own throbbing penis deep into a guy's tight ass. I pull my prick from his mouth and step back. When I look down I see that his prick is harder than ever. "Looks like you enjoyed sucking on my girl cock. You must want me to boss you around. You want me to dominate you and use you. Don't you Nathan?" "Yes Amethyst." "I thought so. I bet you love looking at my curvy girl body and nice boobs while you suck on my dick. My dick that is so much bigger than your little penis." "Yes Amethyst. You're the perfect woman." "Yes I am. All woman, with that extra bit to make a submissive boy like you do anything I want. Now get up and bend over the arm of this sofa because I'm going to give you a present. I'm going to push my big girl dick in your ass and give you my virginity." I run my hand along the side of his face. "You do want my virginity don't you? Every guy wants a virgin, right?" All he can bring himself to do is nod. The apprehension radiates from his face, but he is so submissive he must do my bidding. Before he leans over the couch I stop him and finish undressing him. I want to be able to see his body. He has a lean build and it feels good beneath my hands. But his arse is the focus of my attention. I run my hands over his arse cheeks, enthralled by how smooth and firm they feel. I love rubbing a guys butt so I massage it from top to bottom and back again. I even squeeze them together to see how much cleavage I can create. He is moaning appreciatively. Finally I spread them and get my first glimpse of his quivering little hole. It makes me think of spreading thick grass to find a terrified mouse shaking in fear. But this mouse is going to swallow the cat. As much as I want to just shove my aching cock into him I know that I can't. It's very exciting to dominate him and yet I don't want to hurt him. At least not too much, because taking my penis is going to hurt no matter what I do. I spit on my fingers, something I never would have done this morning, and spread it on his quivering hole. I rub it around the crinkled rim and push some inside. I slide my index finger into him and he unconsciously grips it with his sphincter. The feeling almost makes me cum on the floor. I withdraw my finger slowly and he clings to it, his arse hole pulling out as if it's reluctant to release me. There is no way my cock can get any harder. I glance down at it and see a thin line of clear pre-cum dangling from the tip as if it is drooling. There are so many things I want to do so, so many things I want to try, but right now I can't wait any longer to be inside of him. I work up as much spit as I can and put it in my hand to rub over the tip of my penis. I'm impressed with just how effective this is. I'm super slippery as I place the tip against his tight sphincter and push. I watch the tip start into him, but before I can get the head inside him he clamps shut, squeezing me back out. I can feel him spasm against the tip of my prick. He opens a little then clamps shut over and over. Finally he slows and I feel him relax a little so I push again. This time I do it quickly and pop the head inside his sphincter which clamps down just behind the rim of my cock head. Nathan takes a quick breath as this happens. "Amethyst, you're so big! I want you inside me but I'm scared." "Oh Nathan, this feels soooo good. Even better than I ever imagined! I want to be inside you so badly I'm trembling. Please don't be scared. I won't hurt you on purpose, but I have to be all the way inside you. I can't possibly stop now. I'm going to push some more so try to relax." "Okay. But please go slow." Go slow? How can I possibly go any slower? I push and my shaft begins to disappear into him. I feel his inner sphincter resisting, but I keep pushing. I'm mesmerized by the sight of my thick cock stretching him open and steadily disappearing into him. Nathan begins to pant as I press harder against his resistance. Suddenly I feel the tip pass his inner sphincter and three short seconds later I'm fully inside him and feeling sensations I've never felt before. Nathan is all around me. Hot, wet and slippery, but more than that it's as if I can feel his insides pulsing around me. I make a little circle with my hips and the feeling of him moving around me and with me is euphoric. I am rock hard inside his softness and how that feels is beyond my ability to describe. "Nathan you feel so tight and wet. I love how your arse hole is gripping me. This is the most incredible feeling I've ever felt! I just want to be inside you like this forever!" I grip his hips and make some short strokes knowing that I'm going to cum any second. There's so much I want to do! So many positions I want to try! But they'll have to wait because right now my whole world is my cock in his arse. I'm trying not to cum with all of my might yet I might as well be trying to hold back a Tsunami with my bare hands. "Nathan I'm cumming! Oh hell you feel so good I've got to cum right now! OOOOOH YEA! OH YEA! Ugh...UGH...UGH!" I'm buried in him to the very base of my cock as I pump what feels like a gallon of cum into him. My head is spinning and as the last shot leaves me I collapse along his back. Out of breath and still deep inside him I bask in the afterglow of an orgasm the likes of which I've never comprehended could exist. It built up so high and then suddenly it explodes and is over. No gentle bell curve of rising, cresting and slipping down the back side like I was used to, no this was a rocket launch into the stratosphere and when it was over, a crash landing back into reality. I am crashing as a muffled sob escapes Nathan. I push up off of him and only then do I realize that I'm still fully clothed. My penis is simply popped out of my panties and inserted in this lovely boy's bottom. I pull out of him slowly and watch as he grips my penis just as he did my finger and a little tingle in my balls tells me that it wouldn't take much to be ready to go again, but I'm getting the feeling that Nathan is finished. The head comes out with a soft plop and his hole closes. I help him up and he turns to sit gingerly on the arm of the sofa. "I'm sorry Amethyst. I didn't mean to cry, but you fill me up so much it kind of aches." "I'm sorry too Nathan. I didn't want to hurt you." "That's Okay. Once I get used to you it won't hurt anymore." "You know that makes it sound like you want to do it again." "I do, just not tonight. Things are...a little bit stretched. You're a big girl you know!" I can't help but grin, "Yes, I know. And I wouldn't have it any other way. Can I see you tomorrow?" "Sure. I'll buy some actual lubrication to use." Nathan pulls me to him and lays his head on my chest. I hold him for a while before I say, "I need to get going. I should see if I can get someone's notes to the class I missed tonight." "Yea, sure. I understand. It was fun." "Oh it was way more than fun. At least for me. Thanks Nathan." "You're very welcome my dear Amethyst." I adjust my panties and skirt then head to the door. As I'm leaving Nathan is gathering up his things and says, "See you tomorrow." "I can't wait!" And that's the truth. Actually I want to do him again right now. I can't believe that I feel so horny so soon after bending Nathan over his sofa. I walk through the coolness of the early evening back to my dorm. I have this huge grin on my face that seems to be contagious because most of the people I'm passing are smiling back at me. I get to my room and strip down for a shower. As I'm soaping up my curves I find it very sensuous. I've never enjoyed touching my own body like this and it is giving me quite an erection. My soap covered hands find their way to my new penis and what starts as cleaning becomes pleasuring. I remember that I have a hot date with the captain of the polo team's arse left over from this morning so I place my hands on top of each other with my thumbs making an O underneath. This looks sort of like a stretched sphincter so I imagine that I'm sliding in and out of Devin's tight perfect arse. My boobs bounce and sway in the warm water as I pump him with my cock. Just as I'm getting into tempo I hear someone knocking on my door. I try to ignore them, but they are very persistent so finally I shout out, "Hold on a minute! I'll be right there!" I rinse off and towel down quickly. I'm not completely dry, but what I've missed the thick robe will pick up. Just like earlier I'm having a difficult time keeping my penis tucked out of sight as I approach the door. "Who is it?" "My name's Dev, you don't know me but we have a mutual friend named Caroline who says I need to come see you. It was my experiment that you in inadvertently dumped on yourself this morning. Please open the door!" Caroline told this guy about me? I'm not sure what to do, but since it was his experiment I feel that I should let him in. I open the door to a very excited young man with rumpled yellow hair, fiery green eyes and to my utter amazement he's wearing riding pants and a polo jersey. Dev is obviously short for Devin. He bursts in before I have a chance to invite him and is talking a mile a minute. "They were all laughing at me. I told them it could work, but everyone just laughed. Can you believe it? Of Course you can! People always think they know better! But what the hell do they know! Is it true? Did Caroline really see what she thought?" I'm in shock. The delicious guy I was just thinking of in the shower is in the room with me and he's asking to see my new penis. I guess when things go right in my world, everything goes right. I slip my robe off my shoulders and let it fall into a pool around my feet. His face lights up with wonder and he drops to his knees. I place a hand on my hip and strike a pose like a Greek statue. He speaks to me in a soft voice. "My God Amethyst, you are perfect. Look at it! Look at your penis, your smooth girl cock! It's beautiful! You're beautiful! You're curvy and voluptuous and your penis matches perfectly! I was wrong all along! It was so simple! It required a topical application, not ingestion! I shouldn't have had Caroline drink the serum, but instead rub it on. Can I touch it?" All I can do is nod because I'm afraid that my voice will betray my lust if I speak. Devin touches it like a doctor examining me in his office. He's very clinical and his face is very serious. He runs his fingers along my skin and then squeezes me firmly, making my knees go weak. "Nice and firm." He pushes it up against my belly to examine my new testicles as well. He feels them gently through the skin of my sack and looks so closely that I can feel his breath on them which is driving me crazy. "Is it all fully functional?" I can't stand it anymore so I get a handful of that sunshine yellow hair at the back of his head and hold him steady as I point my cock at his mouth. He grins up at me and says, "I thought you'd never ask." Devin opens his mouth and takes most of me into him in one swallow. I'm still holding onto his head, but there is no need for me to direct him because he's sucking me with a vengeance. He makes Caroline and Nathan look like fumbling high school kids. Devin works me fast, then slow, then fast again, sucking and licking me like he can't get enough of me. I let go of his head and put my hands on my hips, but his grabs both of my hands and puts them back on his head. I can take a hint so I hold on and start thrusting into his mouth. Adoration is pouring out of his green eyes as he looks up into mine across my stomach and past my bouncing boobs. Looking into his eyes pushes me over the edge and suddenly I'm erupting in his mouth. Slightly out of control I push deeper with each shot of cum. "Ugh...UGH...UGH...UGH...UUUUUGGGHHH! Oh bloody hell!" Amethyst: The Girl with a Penis As I get a grip on myself he holds me in his mouth. Gently sucking and rubbing my thighs he keeps me hard. After only a few minutes I'm starting to pump his mouth again so he pulls off of me and stands up. His jersey goes over his head and onto my floor. Now I can see his lean athletic torso. He steps up to me and pulls me into his arms. I slip my hands around him and grab an incredible arse cheek in each one. His mouth is descending so I turn my face up and meet his lips with mine. We kiss long and slow. Our tongues meet and explore each other and there is just a hint of my cum on his breath. This actually turns me on even more because it's my cum he just swallowed. I'm working on his butt cheeks, kneading them with my fingers and caressing the curves as we kiss. He breaks the kiss and I lick my way down to his nipple. I suck on it hard and he lets out a little gasp as I nip it with my teeth. I want him so badly. I want to be inside him, thrusting and shoving my way to another great orgasm, so I pull away, take his hand and lead him to my bed. I pull him into another quick kiss, then turn him around and push him down on my bed. His arse is pushed up in front of me and it looks incredible. So round and smooth in the black riding pants. I reach out and trace the curve of his butt with my finger tips. Long and slow, reveling in the firm smoothness of his body. "You like my arse." It was simple statement of fact. "Yes." I whisper soft and breathy as if we're in the back of a church. "I've dreamed of a girl like you, a woman like you wanting me and taking me. Come and make my dream come true." I didn't need any further encouragement. I step up and rub my throbbing meat along the crack of his arse. Even though I'm swollen I feel as if I'm stretching further. I pull back and run the head down between his legs. With my tip I feel his soft balls through the fabric of the pants and just past them an erection of his own. In my fantasy this morning I took my time and had an orgasm just from rubbing his arse through his pants. That's not going to happen now. Now that I have him here I can't bring myself to wait. I want inside him right now. I reach around in front of him and he rises up to allow me access to the snap of his pants. I undo them and pull them down around his ankles in one fluid motion. I grab each of his cheeks in my hands and give them a good squeeze and he responds by tightening them. I spread him and lay my cock along the crevasse like a brat on a bun. I rub it back and forth and can feel his sphincter twitching along the bottom of my hard dick. Our skin is pulling just enough to be a little uncomfortable so I apply a little of my lube to my prick and some to his hole. I even push my finger into him to make sure he's good and slippery. He playfully squeezes my finger. By now I'm panting with excitement. My nipples are hard and crinkly around the areolas. I want him so badly I'm quivering and I'm sure he can feel the waves of lust radiating from me. I press the tip to his hole and begin to enter him. I love watching him open up to accept my girl cock. How he spreads to accommodate my engorged head. He's a snug fit and he's breathing hard from just having the head inside of him. "Easy love, you're a big girl. Give me some time to get used to you." I'm trying to go slowly, but his butt looks so sexy as it swallows me I can't. I steadily feed the rest of my shaft into him as he grunts and groans, but doesn't protest. Finally there's nothing left and my pubic bone is pressing against his tailbone. I'm completely enveloped in the heat of his arse. I stay still inside of him. Giving him time to adjust and me time to explore all of the sensations. This morning my penis had seemed so foreign to me. Like another being attached to me in some form of symbiotic sexual cohabitation. But not any longer, now it was fully a part of me. He squeezes the base of my prick with his sphincter in a hard concentrated move. Not the quivering of Nathan's over stretched hole, but a firm gripping meant to arouse me further. And it does. "MMMM...Devin that feels wonderful! Squeeze me again." And he does. I'm on fire with lust and can no longer hold still. I begin slowly, pulling back and pushing in. My breasts are swaying in time to my gentle thrusts and my hands are sliding up along his back to grip his well defined deltoids. His V shape enhances the erotic euphoria created by having my girl cock pump his arse. I'm thrusting into him harder now, our bodies making the slapping sounds of skin on skin where my hips are meeting his arse cheeks. I'm already nearing another orgasm and the waves of pleasure are traveling the length of my body like a sine wave along a wire. It won't be long. "If you're going to cum inside of me I want you to do it missionary style. I want to be as close to you as possible. Will you do that Amethyst? Please?" I find the thought of ramping up the intimacy very exciting. "Yes Devin." I pull out of him and he scrambles fully up onto the bed and spreads his legs. This is a sight I've never contemplated. Seeing him on his back in all of his chiseled muscular maleness with his legs spread waiting for me to enter him again. It's an unbelievably erotic sight. I follow him up onto the bed, my heavy cock bobbing with my movements as I position myself between his legs. Devin reaches down and takes my penis in his hand to guide me to his waiting hole. When the tip touches him he squeezes the base of my cock and pulls me into him. I readjust my legs so that I can penetrate him fully and lean up over him. Now my face is inches from his and the intimacy of the act has increased a hundred fold. My nipples barely brush his smooth chest as he wraps his legs around me and squeezes my hips tightly against him. Every inch of my penis is buried deep inside Devin and the look of ecstasy on his face is unmistakable. Holding me inside him he finds my mouth with his and we kiss. While we're kissing I begin to pump his tight arse again. One of his hands finds its way to my breast to play with my nipple. This adds a whole new dimension to the pleasure I'm feeling. My nipples have always been sensitive and the attention he is giving me in conjunction with having my cock in him is like kicking in the afterburner on a fighter jet. I'm breathing so hard I can't sustain our kiss. I'm franticly pounding Devin's delicious arse and just when I don't think I can get any higher he bends tightly down and takes my other nipple in his mouth. My world explodes! I grab the back of his neck in one hand as I hold myself up with the other. I pull him hard against me as his tongue flicks my tortured nipple and erupt into him. I have him bent near in double as I cry out. "OH MY GOD!!! OH...OH...GOD...YES! YES! YES!" I punctuate each shot of cum with by pulling him harder against my breast and thrusting fully into him. When I'm finished I release Devin and he flops back onto the bed gasping as I collapse on top of him. We lay like that drifting in a haze of post orgasmic rapture. "Amethyst. That was incredible. Better than anything I have ever imagined!" I roll off to lie beside him as I finish catching my breath. "It was phenomenal. You were so into having me inside you that it really turned me on. I just want to make love to you over and over. I say let's take a quick nap and do it again. What do you say Devin? Are you up for it?" "Absolutely." Devin rolls onto his side and I spoon up behind him and with my half hard penis nestled in the crack of his perfectly shaped arse, I drift off to sleep the happiest girl in the world.
