Looking up over her new breasts, Danielle saw a young man approach her. The boy was a handsome blond with a thick, hard cock between his legs, who had clearly scented the musk of a female. His pheromones were as irresistibly enticing to Danielle's new form as her own were to him, and she quickly felt herself get wet and noticed her nipples becoming erect.
He straddled her, his penis touching Danielle's stomach, and the two kissed eagerly. Once they broke their kiss, the boy's hips moved so that his penis touched her newly-formed slit, and he slowly pushed inside, holding her hands.
The feelings were amazing. Danielle gasped with pleasure at how his shaft spread her body open, rewarded by the intense pleasure of physical touches against her most sensitive points. With a look of concentration and ecstasy on his face, the man slowly started thrusting his hips, panting and groaning and holding her hands tighter as he gradually grew faster.
In response, Danielle wrapped her legs around his back and moaned appreciatively, trying to encourage him. Her thought process and desires were wholly feminine and attracted to masculinity- her body NEEDED him to fill her with his seed and impregnate her with a brood. She was as irrefutably feminine now as Daniel had been irrefutably masculine when he came into the enclosure, and as he fucked her, she grew closer to her newly changed biological purpose.
At last the boy let out a grunt of pleasure, and he filled Danielle's pussy with his cum. The warm wetness of his semen's contact with her body pushed Danielle over the edge, and she moaned eagerly as her walls clung to his thick ejaculating shaft until his release finished.
The two kissed passionately, and the boy climbed off her and went away. Smiling, Danielle wondered if he would soon shed his manhood as she had, and sighed contentedly as his seed seeped into her.
