"I'm not playing your stupid games." you say, angrily. You try to rise to your feet, but only get as far as your knees before the legs of a pair of leggings wrap around your neck and pull you onto your back causing you to land in a pile of soft cloth. The legs and sleeves of various articles of clothing wrap around your arms and legs. Try as you might you just can't struggle to your feet. The woman in front of you squeals happily and applauds.
"Oh, I'm so happy you said that!" she says "You'll look so pretty when we're done with you."
"That's not what I meant! I'm getting out of here right now!" you say, trying to rip free of the clothing, but by some miracle no matter how much you pull at the delicate fabrics of the women's clothing, you don't hear so much as a snapped thread to ripped fabric. You gasp as the pink pair of panties that earlier covered your mouth slide over each of your ankles and begin sliding up your legs of their own accord. As they do your legs take on a hairless and decidedly feminine shape.
"I beg to differ, sweetie, you're staying here for quite a while." she smiles. Your heart races as the panties climb over your knees and inch up your legs. With every inch your legs change shape and your skin begins feeling softer and more sensitive. You try to kick your legs, but it does no good.
"I changed my mind, I'll play your stupid bottle." you say, your voice taking on a pleading tone.
"Too late, beautiful. Looks like your days of playing the tough guy are over." she says with a wink. You watch in horror as the panties slide firmly around your buttocks and over your crotch. As you to your abdomen tingles and gurgles slightly as your biology shifts and your bottom takes on a rounder shapelier form. Your manhood quickly pulls into your body and disappears as a moist vagina pushes between your legs.
"No, no, noo..." you call out. From there the fight largely disappears from you as the transformation quickly finishes. A front-snap bra wraps around your chest and fastens. You watch as a pair of breasts form before your eyes. Your torso follows suit, becoming hairless and female. Your yells for help begin taking on a higher pitch as your neck becomes slender. You feel the tickle of hair brush against your back and you watch as light brown locks of hair fall over your head. By the time the clothing finally releases you you've completely transformed into a rather attractive female.
"Yes, yes, yeeees..." your tormentor says. Before you can stand up she's removed her own clothing and has her warm soft body pressed against yours. She kisses your neck and slides her hands down your side and beneath the magical panties. She slides her fingers over the new, wet addition beneath them.
"No...." you whimper, the feeling of this woman fondling you fills you with unfamiliar pleasures.
"Yes..." she whispers in your ear. You begin to pant as she picks up speed, her fingers expertly dancing inside you. You try to block out the sensations long enough to push her away, but as your climax begins stirring within you, you find yourself wrapping your arms around her back instead. You can practically hear the triumphant smile in her voice as she says "yes" again and and again thrice more. Soon you've lost all will to fight and chanting yes along with her.
"You're mine." she says, and with that the pleasure within you overflows into your first orgasm as a woman. She looks at you with a smile. "You're mine." she says again. You shake your head with a frightened look on your face. But she places her hands on your shoulders and presses you down against the bed of clothes you lie on. She straddles you and looks at you with a wicked grin.
"Don't deny it, my sweet." she says "You...are...mine." she says. You say nothing in response, but the look on your new face must show the resignation you feel, because she pulls you into a long kiss. You realize, or perhaps rationalize, that at this point there's really no escaping. Your in a strange body in a strange mansion in a strange world. You doubt your lover will ever change you back. She smiles and whispers "good girl" into your ear before pulling you up and dragging you into a bedroom. Several orgasms later you're both asleep and by the time you wake up the next day you're only marginally certain you were ever male in the first place.
