You struggle against Sarah’s overwhelming power, but to no avail. Exhausted, you collapse on the mattress without any fight left in you. Sarah giggles and seals a kiss against your lips, swishing her tongue deep inside your mouth. Simultaneously, she guides your erect cock inside her vagina and begins to heave her hips up and down, sliding inside you. The pleasure is overwhelming; your vision fades to gray as waves of arousal surge through your entire body. Within moments you climax, discharging a month of pent-up semen inside of her. But that’s only the beginning. Even though you have nothing left to offer Sarah, she doesn’t stop thrusting against you. You begin to feel a bit strange. Your cock seems to be pulling out of her, but she isn’t altering her range of motion. Her tight pussy doesn’t seem quite to small anymore. It barely satisfies your manhood; you might as well be fucking jello. But as one sensation dies, another begins to emerge. There’s one tiny little spot that is suddenly amazingly sensitive. Sarah reaches a finger to it and begins to rub, causing you to gasp as your muscles contract with a new wave of erotic gratification. You don’t care whether or not your cock can feel a thing. Come to think of it, your entire crotch feels almost completely smooth against Sarah’s hands. She can run her fingers straight from that sweet, sensitive spot straight to your rectum undisturbed. What is this? You peer up and notice that your nipples have swollen. Each stands enormous and erect, jutting out by nearly a centimeter. Your areola have grown in diameter until they’re an inch and a half wide. This isn’t normal… neither is the fact that you’re starting to notice some curvature between them. Slowly they rise higher up into the air as two globes of fatty skin begin inflating beneath them. One by one your chest hairs withdraw back inside your body, leaving your swelling chest perfectly smooth.“Sarah?” you gasp. Your voice sounds different, like you’ve just inhaled helium or something. But not unnatural sounding, just higher pitched as if you were a high tenor… or perhaps an alto? Even your breathing seems softer… lighter…Sarah suddenly buries her head between your legs and begins to lick your sensitive spot. You arch your back, your legs quivering with the shooting pleasure. But then you notice something new… you feel a protrusion poking against you, not against your skin, but… inside you! How is this possible? Sarah giggles as she thrusts here fingers deeper in, hitting a new, unfamiliar series of nerves. It finally dawns on you… you have a vagina! You hear sharp cracking sounds and feel your hips slowly tear away from one another, widening with your swelling ass. You’re turning into a woman!“Oh baby…” Sarah moans as she thrusts several fingers as deep inside you as they can go, rubbing furiously against your pussy walls. You let out a long, high-pitched shriek as sheer sensual bliss flushes through your body. Your crotch is warm and damp; you can hear squishing noises as your cum leaks out of you. With the combination of Sarah licking your clit and her fingers pulsing inside you, your pleasure grows like water at a dam until your entire body is shaking, your throat emitting girly squeaks involuntarily. Yes… yes… this is amazing… stronger… stronger… How can your body possible bottle up so much? When will the sensation stop growing? But then finally you climax. The built up pleasure tears through every inch of your skin and body. Eyes, wide, you gasp and your body legs clamp tight, opening and closing as pleasure bounces through your veins. You are absolutely lost in this ocean of lust and sensation. The world around you fades. Nothing matters but the eternal pleasure. Sarah… Sarah… Your beautiful lover… As your orgasm subsides long enough for you to regain your senses, you flip her on her back so it’s now you on top. Your enormous breasts swing with the motion, dangling down so that your nipples brush her naked skin. Your hair has grown and covers your shoulders in a thick canopy, tickling Sarah’s belly as individual strands gather on top of it. You are absolutely female, from your narrow waist to slender arms and curvaceous legs… your pussy drips with juices and your breasts bounce with your every small motion. You are a chick. A fucking hot chick. And it doesn’t bother you. Why should it? You’re beautiful. Sexy. No one can resist you. No one. You can give anyone endless pleasure, orgasm after orgasm. And Sarah is right underneath you, your lovely, horny sister… it’s time for you to repay her for her efforts. You devour her salty fluids as they trickle out of her, running your tongue up and down her labia in long, forceful strokes. The more she screams, the faster and harder you go. It doesn’t take long before she’s the one trembling and gasping for breath. You could pleasure her for hours. You don’t feel tired, not in the slightest. You’re not entirely sure where you are. A hotel room, of course. And this chick you’re pleasuring, is she your girlfriend or something? She’s definitely your sexy lover. You can’t think of anyone whose sexual energy matches your own except for her. But it’s a pity there’s just you two. You could bring someone else into the mix. A cute guy. Together you and Sarah suck his cock and tease his balls. Sarah could give him a tit job while you bury his face in your own luscious breasts. And then he’ll ejaculate and you can taste his warm cum on your skin and in your hair… “We should go find some new blood,” you tell Sarah. “There’s hot guys all over here. So many people to fuck…” You giggle. “So many guys missing out on us two wild fuck machines…”You hear a knock at the door. Both you and Sarah sit up and look at it, completely naked. “Room service,” you hear from out in the hallway. It’s man’s voice. Oh, what a coincidence… you have your lucky guy to complete your amazing threesome…
