Of course you dare.

"Alex, the next part of the treatment is crucial. We'll need to perform it as often as we can, even possibly outside of this office but especially during our sessions. As I've warned you: everything I say and do, no matter how crass or wrong it might normally be, is only part of the treatment to complete your transformation. Do you understand?"

Alex squirms as you finger his unbelievably tight little cunt a bit more, but nods. "What's... what's next...?" He tries his very best to sound like a man as his voice peaks whenever you hook hard into his labia.

"I'm going to fuck your little pussy, Alex." Silence... and a whimper. You don't let up. "This is embracing your womanhood to finally be rid of it. I'm going to fuck you, hard, and fill you up until you're finally, physically a man."

Your undo the buckle of your belt, and Alex suddenly starts breathing in short, rapid breaths before he manages, "I-I can't do this! This is... this is too much-!"

"So you'll accept being a woman? It's what will happen, for good, if we stop now."

"Oh... Oh God, oh-" Alex continues to hyperventilate as you ease out of your pants, and covers his eyes with both hands as he begins to cry. Reaching under the chair, you pull out a strategically-placed tube of KY, and apply it liberally to your throbbing meat as you contemplate the freshly saved cooter awaiting your christening. He glances down as his breath steadies, and covers his face again as despair takes him anew.

You almost feel bad about how hard it makes you. You grab his legs and part them, and without even the use of your hands begin to guide the angry head of your manhood against him. "Close your mouth... and cover it, or else the scream might be too womanly and reverse the entire process."

"What-?!" Your head peeks the very tip into him, and he clamps his hands over his mouth. The lube is all that allows you past that impossible gateway; his squirming, his screaming into his hands, his eyes screwing to a close as you press on, it all proves he'd never get wet enough without help for his first time. You put his legs up on your shoulders, and grab his waist now that you're mere centimeters inside and pressed against his thick hymen.

It's all the warning he's afforded as you thrust with your entire weight behind it. A high-pitched wail tries to escape his hands, and he shakes his head in useless protest. The hymen is intact. How thick was it?! You're too determined now. You hold on to your prey and start shifting your hips as you dig around, pressing the hymen in different angles, tugging at flesh that didn't want to tear, but had to tear, and Alex's legs kicked against you in useless protest. His labia stretched around you; you sunk in another centimeter. It was giving in. A trickle of blood dipped onto the bleached white towel, mixing with the remnants of the shaving cream.

Something popped. He knew it was coming as you backed up, but could only scream into clasping hands as you finally thrusted through.

The sensation of tearing, and you're finally inside him fully. Tears roll liberally from his eyes and blood weeps from his new wound, but the KY managed to keep him otherwise unharmed by your wrathful deflowering. You remember that he hasn't had his period, thanks to the hormone blockers; you had no reason to pull out until you were finally done, and the way he gripped the invader, even if involuntary, was so naturally gifted as to masturbate you without your moving. You focus on not coming for as long as you can manage, trying to think about math (your most hated topic) and Mrs. Wentworth (your meanest teacher).

"Please..." he manages to squeak, and all your efforts are nearly reversed at how pitiful he sounds.

"We're almost done here," you growl. His opinion of your stamina probably didn't mean much anyways; you'd have plenty of time to get used to it, even if it did. You stare down at your union, and at the unnatural lump your cock forms on his clean pubic mound, and you stifle your own moan as you slowly withdraw, watch the flesh flatten back out, only to thrust back to the hilt once again. He covers his mouth, stifling a scream, and you're off to the races now that he's properly shut up, blasting your cock against his useless uterus until you're sure his cervix will remember you. You keep this battering up as much as you can, parting and expanding that poorly-developed birth canal with your girth, until you feel pressure building inside of you.

You lean in close, holding his thighs together while pinning his legs against him. He's so flexible it's criminal. "I'm going to cum inside you, Alex," you moan near his face. His eyes, the eyes of a terrified woman, reflect your grunting face and shimmer with tears.

"No!" he manages between his clutched fingers.

"The male hormones are required... and they're most effective... in your most important... place!" You can barely manage your latest fabrication as you shove yourself inside and press, and press against his cervix. His eyes roll into the back of his head as he nearly passes out... but is revived by the first pulse of your baby batter inside him. "Take it, you stuck-up... little... slut..."

"No...!" He doesn't kick you off; he couldn't if he wanted to. He whimpers and squirms as you blast wave after wave of swimmers inside him, flooding all the blood of your union out with pent-up seed, and the red-gray mixture glops onto the towel as you stay inside him.

You lick a tear from his face and remove his hands once he stops screaming. Your mouth and tongue forces him to comply, and you kiss your transgender patient deeply, like the woman he was born as; like the woman you'll make him.

He kisses back; he can't turn back now. He has to become a man, and you're his only way there, now.
