At the precise moment of full penetration, Nick’s feminizing process becomes erratic and confused. Laura gasps in delight as she looks down to find Nick grunting and sweating with pleasure, his transformation accelerating to a visible degree. Laura watches with amazement and sudden confusion as Nick’s body takes on the slender shape of a female. His hips widen and expand, his waist shrinks somewhat, and his features become less muscular.
At the same time, even though he has a female body, Laura delights with the realization that her lover’s penis is enlarging inside of her. The feeling of his organ swelling thicker and stretching longer inside of her is enough to drive the doe to the height of erotic bliss. It slowly grows deeper inside of her, massaging her walls as it thickens up and lengthens. Nick’s maleness grows and fills the doe so completely that she feels the tip tickle her cervix. Laura lets out of a terrific cry of pleasure and shivers.
She looks down at Nick to find the oddly changing human’s face starting to extend into a furry muzzle. His eyes look up at her with utter helplessness, and Laura grins. The doe begins to ride Nick’s tremendous cock, stimulating the both of them by rhythmically lowering her loins up and down over his length. It takes little time before Nick is in the throws of passion, as his face completes into a deer’s muzzle.
At the same time, Nick is changing more than Laura can see. His testicles enlarge into two tight perfectly round spheres, and right behind them a small pocket begins to form right between Nick’s legs, becoming deeper and more sensitive by the second. A vagina, Nick realizes, even as the doe pounds his cock and brings him to the edge of climax. Nick gasps, grabbing hold of Laura’s thighs with both hands and urging her on, thrusting his meat into her with reckless abandon.
The doe squeals, and Nick feels her innermost regions grab hold of his rod tightly, squeezing it with incredible muscle control and constricting him tighter. Nick tries to hold on, but the sensation is far too much. He feels a blast of cum spill from his tip, and begins ejaculating wildly into his partner. Nick’s vagina develops enough to feel climax as well, and it begins to drip with a warm clear liquid down his furry inner thighs, taking his arousal to amazing new heights.
As Nick finishes releasing his load into Laura, the doe sits on top of him for some time, panting, before she dismounts with a loud slurping noise and sits next to Nick, stroking his feminine chest. “Laura,” Nick says weakly, in a very girly voice, “what’s happening to me?” The doe looks him over. He is a full anthro doe like she is, but the bulging foot long penis is certainly not female.
