The big thing that stood out to Ty was how he kept thinking about what it had been like to be a girl. When he had changed sex, she had felt things he'd never even imagined. Her body had been so different, her desires so enticing, and what she and Eileen had done was amazing. Just remembering how Eileen had fucked her, filled her with cum and gotten her pregnant was giving him an erection.
Ty could barely stand it- he wanted to be a girl again so bad! He locked the door, stood in front of his bedroom mirror and stripped naked. His T-shirt was thrown to the ground, he pulled off his cargo pants and stepped out of his boxers. And staring at himself in the mirror, he wished eagerly to turn into the girl he had been again.
Shivers raced through Ty's body as it slowly began to alter according to his whim, and he watched in anticipation and amazement as he transformed. His skin turned smooth, its thin layer of hair vanishing and its texture turning more supple, and his body shrank all over as he became shorter and his body more petite, his arm and leg muscles now more slim and his hands and feet more small. His figure slimmed inwards in some places and flared outward in others, most obviously his hips, which became curved and wide.
Further up his body, his shoulders slunk inwards and his larynx shrank to a feminine size, making his voice's pitch increase. His face now resculpted into a more feminine appearance, with a narrower neck, softer cheeks and puffier lips forming while his hair lengthened down his back. It amazed Ty just how different he looked already, and the biggest changes were only now upon him.
A wave of excitement swept over Ty as the changes now reached his genitalia. He felt a warmth spread through his chest as his nipples widened, swelled and grew more sensitive, and he rubbed them eagerly. A soft moan escaped his lips, the pleasure intensified by how it made him feel more prepared to relinquish his manhood. He saw his chest fill out, large soft mounds of flesh forming under his touch as he sprouted breasts. By now his body looked almost totally like a girl, and it wouldn't take long for the rest of it- and his mind- to catch up.
He felt the sensations shift lower down and affect his crotch, and watched with anticipation as his penis began to shrink back into him. It clicked in his mind: she would not need it. His testicles moved up inside him and reshaped into ovaries, and he felt a sense of castration- and yet it felt nice. She could get pregnant now, and the concept was deeply enticing to her. And as his penis formed into her clitoris, a tiny sensitive nub between her legs, and his scrotum became almost flush with her crotch and then a vaginal slit emerged down its seam, she rejected the male gender and embraced the female.
Ty was even more glad to be a girl again than she expected to be. But now she wondered what to do...
