"Yes"

“Get up on the bed and spread your legs.” She commands.

Wait, you never wanted to be used like this. What is happening to you? You’re now a woman? Is she still a woman? Why is that cock so enticing? What is this throbbing ache in your groin? What are you about to do? Are you a virgin? Will this hurt?

“Well,” She says, “Did you like sucking my cock?”

It felt so good. You’re still so turned on by it. You can’t get the thoughts out of your head, to suck, to lick, to taste. You did like it and you want more, to feel it inside of you. Your head nods in agreement.

“Well then, if you want to continue, you’re going to have to let me fuck you.” She says it so pragmatically. “Besides, that hot cunt of yours is going to love it. So get on the bed.”

"Yes." You reluctantly admit as you climb your way to the bed. There is this need you feel within you. This throb, throb, throbbing from down below. Perhaps she’s right. You do want that hot cock inside of you, to feel it sliding in, to feel it splitting you, this desirous need to be filled has been growing and you can’t wait to sate it but it’s still difficult to admit it to yourself.

You lie down on the bed, timidly… nervously, with your legs only partly spread. She approaches, her massive pulsing cock in hand as she slowly strokes it back and forth. She climbs up on top of you, working her way between your legs, pushing them to the side. Her red curly hair swaying with her motions and she looks down at your warm honey pot. She runs a finger up your moist cunt and sudden tingles shoot out again from within. She brings her hand up to her mouth and you can see the wetness glistening on her finger.

“Mmmmm.” Her lips smack as she pulls her finger out, “You taste so good. All hot and ready for me.” She bounces her cock on your pubic mound and you feel the combined lubrication of your spit and her pre-cum as it hits. “And my cock is hungry for that fresh pussy Jane.” She looks up at you, “Do you want me to put it in?”

There’s a slight hesitation, but it’s quickly overcome by that continuous throb, throb, throb. "Yes, put it in!"

Samantha smiles as she rubs the tip of her big dick against your clit, teasing you. Your body squirms below her as she says, "Beg me Jane. Beg me to fuck you with my big girl cock!"

And this time, without hesitation you respond, "Pleeeease! Sam, put it in! Fuck me with your big girl cock!"

Why did you say that? It's all so surreal. Here you lie, a woman now, with Samantha straddling you, the taste of her cock still fresh on your lips, and you're begging her to fuck you with it. Somewhere in the back of your mind you want to resist but you can barely get past any other thought at the moment. You want her cock. You need it inside of you. There’s this emptiness within that only she can fill right now.

Sam giggles as she runs her cock over and around your clit. And then she looks back up at you and smiles as she slips the very tip down towards your entrance. You’re pleasantly surprised by the warm tingling sensation that quickly spreads out around the point of contact. You remain quiet because you fear not getting her hot shaft inside of you. Throb, throb, throb. And so, as you lay nervously still, she pushes gently until just the tip of that wonderful cock slides inside of you.

You gasp in sheer amazement as the sensations extend outward from below. Your eyes widen at the realization of new nerves being tapped and bringing forth new pleasure.

“Uhhh” She groans. Gasping with delight. She’s entered you. She’s filling you. Something about her cock is enticing. Potent. Powerful. It’s as though there’s some nudge inside your mind, pushing you to open up for her, to give in to her for you know that you're also giving in to yourself. Her cock feels so huge at the moment but she just has an inch inside you. The sensation is new and exciting and strange all at the same time. Yet you still crave more.

But then she thrusts forward. The same cock you got all lubricated up, that you worked over and sucked on deliciously is sliding into your pussy. And everything starts to feel just right. You moan out in sheer delight and she grunts in return, claiming your cunt with that pulsing shaft as it enters deeper. You feel new muscles tense up around it, gripping her in return. It’s as though you can feel each vein, every small detail of that cock inside of you, rubbing against you.

“Oh yeah. That pussy is so tight! I knew you were gonna be a great cock whore!” She smiles down at you as she slowly pushes yet another half inch inside of you. “Do you want it all?”

GOD How big can she be? You wonder. This fullness is already overwhelming and there’s still more? She’s stretching you and filling you at the same time, yet you truly desire all that she can give you.

"Ooooh GOD!" You try to resist groaning. You don’t want to let on how much you’re liking this. She pushes more into you. "Ooooh" it’s hitting just the right spots. Part of you thinks, “Oh no, her cock is in my pussy. I won’t get to taste her cum. I won’t get to suck her off.” Those thoughts come unbidden to your mind yet you’re losing yourself in the moment, in the sheer bliss of it all. There’s a slight pain in the stretching and yet it’s a good deep massaging pain releasing these tense new muscles within.

You feel one of her hands on each of your hips as she pulls you into her. You hear a smacking of your cunt against her groin and you feel a profound sense of fullness. Every little vein on her wonderful cock, pressing inside of you, massaging you, making your arousal oh so obvious. Maybe some groans escape. Maybe you just say “Yes, Yes, Yes”. Remembering her questions. Remembering her inquiry about what you wanted.

She leans down and wraps her arms around you. You stare into her green eyes as she looks into yours. She moves in closer and your eyes close as you kiss. A deep and full kiss, her lips pressed gently against yours, your two tongues intertwining. And she slowly begins grinding away at your hips, probing your pussy with that new girl cock of hers. There's this pristine feeling of being connected in such a way with another person, something you've never experienced before, and it's amazing.

She pulls away after a bit, raising her torso just a few inches above you . "Now, Jane, do you see what's it like to be a woman? How wonderful it can be to have a cunt? To feel that fullness?" And she plunges back deep within you.

You gasp for breath as she bottoms out and your clit is stimulated by her groin rubbing against it. Oh, the sheer pleasure of the combined sensations is immense. You’re not so sure how long you can keep going before you cum. And then the rhythmic thrust commences. Samantha’s cock is now repeatedly plunging into you. You feel your insides exciting with each insertion as you gasp every time. Your new full and round tits bounce with each slam. You’re only partially conscious of the screams emitting from your lungs indicating your ecstasy as the heated throb continues to boil within your loins with each thrust. Stroke, stroke, stroke. Her incessant fucking is all you want right now. “Yes, yes, yes!” You squeal, thinking of how her wonderful cock will soon be squirting within your pussy. Filling you. Releasing her milky load of cum as you suck it in. Drinking it down. Then, the words escape your mouth.

“Please… Please, cum in my mouth.”

The idea passes through you. You want her to cum into your mouth. You want to suck. You want to swallow. You want to serve that wonderful slick thrusting cock. But you’d rather be using your mouth to suck it. You’d rather be up close and personal where you can just cross your eyes, zone out, and suck all your thoughts away…

But there’s nothing for it, she’s hitting the best spots inside of you… thrust, thrust, thrust…. Again, and again, and again. Even the quiet smacks of her working in you, the moans she’s letting out. They are almost deafening as you lay there crying out in sudden surprising pleasure. Ooooh this feels so good. Maybe you find yourself pressing back into her, but as you feel her and yourself on the verge of cumming she explains, “Don’t worry. I’m holding back. If you’re a good girl then I will let you drink my cum when I squirt."

"Now, Tighter.” The instruction goes right down your torso. You feel yourself clenching your insides around her massive cock. Gripping it with all you can and noticing the tightness that is your own pussy. You feel the unexpected aggressiveness of your partner as she slams harder and faster into you... thrust, thrust, thrust. You feel it entering and leaving, it's becoming easier. There's a dull hum of pleasure from your groin. This just feels so right. You're glad that you came here to the laboratory with her. You're glad you got to taste her and you can't wait to do it again.

Being the vehicle for her pleasure feels so good as she continues... thrust, thrust... she's filling you, flooding you, using you. You're both the user and the used. And you feel as though you are only along for the ride, like a sleeve for her wonderful cock. And you want her to keep doing it, to let your body spasm and cum just from being filled with her cock...
