Ty paused and thought to himself... what would it be like to be a girl? He'd always been curious what boobs and a pussy feel like, and he was pretty unsure about his sexuality, so he thought he'd try becoming a girl.
Locking his door and stripping naked, he made his wish. Almost instantly, he felt warm and tingly all over his body; every male cell in his body was slowly becoming female, one by one. His penis shivered as it hardened between his legs, female hormones rewriting its purpose by the second. His nipples tightened into erection and stood up on his chest harder than they'd ever been. Ty shuddered with intense pleasure as his transformation made even his fingers and toes shaky with excitement. As they wavered before his eyes, His arms and legs, fingers and toes, chest and back, slimmed and softened, hair receding away, muscles thinning to feminine proportions, every cell being changed.
Ty watched in the mirror as his face softened and became more feminine. His hair seemed to grow a little, and his lips enlarged a little. Even his eyes tingled with pleasure as they changed. Looking in the mirror, he saw his hips slightly widen and his waist draw itself in a little. As his gaze met his nipples, he suddenly felt them release a little surge of pleasure, before the skin around them started to bubble like a liquid. He watched as mounds of flesh inflated gently below them, gradually budding into sensual D-size breasts. He let out a soft sigh that ended in a gasp as he noticed the growing femininity in his voice.
He trembled with pleasure as he felt his testicles tighten up and wither as they moved inside his body. His penis wobbled as it tried to shoot semen, but had nothing to let off. Then it too began to atrophy, sinking into his skin. Just below it, the loose skin of his scrotum shifted up and expanded around his slowly shrinking penis. She let out her first female moan as what had been her scrotum began to invert at its bottom, the vaginal tract that her testicles, now ovaries, had already been forming inside her now forcing its entrance to form. Her penis had receded into just the head, which was shrinking away into a tiny clitoral hood, as her vaginal lips finally tucked together, her pubic hair thinned into a small fuzz, and her vaginal tract and womb completely formed inside her.
Ty looked down at herself excitedly. "Oh man," she murmured in her feminine voice, her nipples and clitoris engorged and her pussy moist with excitement.
