Surprise Butt Sex.

He reaches over to the night stand and pulls out an unlabeled tin before continuing. "See, it's fine for a man to play with a sissy's clitoris, but sissies and women only have real pleasure from one thing, and that's getting fucked with a man's cock in their pussy. Get on your knees, sissy."

You obey, clit twitching underneath you as you get onto your hands and knees. You can see him slathering the contents of the tin on his cock until it’s alluringly shiny and slick, and then you feel his hands grip your waste. You open your mouth to plead or protest, but before you can, there's pressure at your back door, and then he's sliding inside you. Pure pleasure, none of the pain you expected, rolls over you, and its within the first few strokes that your already aching clit spasms again, a rope of cum splattering on the sheets. It keeps coming, one shot after the next, until it's just a steady dribbling stream of jizm leaking in a puddle at your knees. He presses a spot inside, a pleasure button that seems to grow in size and intensity as you moan and gasp, your voice climbing in volume and pitch.

"This is your boipussy, sissy. Once you come from getting fucked in your pussy, you can't pretend you're a man anymore. Your body catches up with your mind, and it realizes it's worthless as a male. Once you've leaked all your semen out, once I've fucked you impotent, that little clitoris will become nice and soft and small like it should be. Does a man have a soft clitty?"

"No!!" you whine, your whole body shaking from each impact of his hips against your ass. His cock is hot, pressing deep inside your pussy, so intense you can barely answer him.

"Should a man have wide hips to grab hold of?"

"N-no!"

"Should he like having someone play with his tits?"

"Nooo!"

"Should he whine and moan like a bitch when someone fucks his pussy?"

"Noooo..."

"Damn right," he growls, and holds you tight against him as he empties himself inside you, filling your tummy with hot seed. You shudder, a current of pleasure arcing through your whole body, but it lingers, not fading quickly like the quick flash earlier. This one stays, keeping you shivering and twitching as your clitty bobs limp beneath you, not a drop of cum left inside of you.

"Look in the mirror," he instructs you as he pulls out. You stumble off the bed, no hesitation to obey his command. Looking back at you is a girl, or is it? She has breasts, small enough to be considered more girlish than womanly, but definitely breasts. Her stomach is trim, her shoulders slim, lips full and eyes doe-like. Hair runs down to her shoulders, and her hips accent her coltish legs nicely. Between them is a soft, pink thing with flat skin below it.

"Your sack's empty, and I doubt you can get hard anymore. Your breasts will continue to develop, and your ass is already rather full. The potion's all but run its course now. Only one thing left to check," Svier says. "I can give you a counter potion that will reverse most of the effects, or you can be a slut for the guild from now on."

You look back at him, and he smirks.

"I see. Well then, you can start by climbing up here and practicing using your tongue, slut."
