He transforms into a woman

The wizard screams out in pain as his body absorbs the demon's spell. The **** of the spell shreds his clothing... Or perhaps it was a component of the spell itself. Indeed, though he seems to be crying out in pain, there is no visible injury to his body. Instead, his cries of pain slowly become moans of pleasure. His cock becomes erect and he begins stroking it furiously with both hands. He squeezes his eyes shut as he vigorously masturbates. With his eyes shut, he doesn't notice the changes in his body that have already started.

You watch as first the hair on his arms and legs disappears. Though he was already clean-shaven, his stubble recedes as his jawline shrinks, his face becoming subtly more feminine. His hair begins growing, his close-cropped cut soon reaching his shoulders. It also begins changing colors, lightening from a dark brown to a silky blond starting from the roots. His shoulders themselves narrow, starting a larger transformation in his torso. His chest, just recently devoid of hair, is already less broad and muscular. His nipples are fully erect and growing, leading an expansion of his breasts which already are slightly raised from his chest. His muscular abdomen visibly softens and thins as his hips widen. His arms and legs are also less muscular, with dainty, almost graceful hands and feet at the end.

He doesn't stop his furious masturbation as all this takes place. It seems his manhood will be the last part effected by the spell. Soon, however, as his hair stops growing at the center of his back, his breasts fill out at a respectable B-cup, and his hips and waist finalize into a distinct hourglass shape, he begins moaning as his last ever orgasm with his own penis begins. He holds the base of his manhood as several streams of cum shoot out and fall into the floor. It is quickly obvious, however, that the last remnants of his masculinity are disappearing. He continues moaning through his climax, but his cock has already stopped producing semen and has begun shrinking. It continues retreating until he cannot hold it in his hand anymore. He drops his hands to his side, breasts heaving with slow, heavy breathing as he recovers from his orgasm. This allows you to watch as his cock and balls continue to shrink until both disappear entirely, replaced by a light pink, virgin cunt with the tiniest tuft of blond hair adorning it.

The demon walks up to her and smiles. She looks up at him at first with fear over what he has just done to her. However her attention is soon pulled to the massive cock hanging directly in front of her, which she stares at with lustful eyes as a drop of drool rolls down her chin.
