She resists...at first.

"N-n-n-oo, I must resist!" Screamed Kate Moss as you rubbed your hard cock against her ass, "But surely Kate you can feel my instrument of pleasure." Suddenly she moves to run away, but you were too smart for that and release a cloud of pheromones into the air around you.

Almost immediately they take effect, "S-s-s-so you're just here to give me p-p-p-pleasure?" "Yes my dear." "Then what are waiting for? Fuck me now!" With those words you pounce, removing her clothes and sticking your tongue up her slit whilst rubbing her clit with your fingers. After five minutes, you pull her on top of your cock and drive it up her moist slit, fucking her silly. "W-w-w-w-w-why c-c-can't I cum?" She moans as you shove your tailcock up her ass "Oh you will my child, you will!" After another fifteen minutes fucking, you release your demon seed into Kate Moss's womb, the transformation is instantaneous, her skin goes a dark shade of red, her wings unfurl from her back as her tail and horns extend themselves out of her body.
