Ty's instincts soon made her decide what to do with her body. With her mind still wandering to newly sexual thoughts about men, her body responded in kind- she felt her nipples and clitoris become erect, and female juices slowly leaked from her slit. She felt aroused and tense in a way she never had before, and had to indulge it.
She carefully massaged her breasts, and soft whimpers and moans escaped her lips as she felt unfamiliar pleasure. When she pinched her nipples, she felt intense sensations course through her, nothing like anything he'd ever felt as a boy.
A boy... oh fuck, it'd feel so nice to have a boy or a man hold her tits in his large, warm, firm hands! Ty wanted so bad for one to play with her boobs. Every touch would remind her how feminine she'd become, and she'd be able to practically feel his lust as he fondled her. Maybe she could stroke his cock in return, or he'd shove his big thick penis between her boobs...
Thinking of penises reminded her of the changes to her own form, and she looked down to see a trail of moisture around her inner thighs. It still felt odd to see a flat mound where she'd had a protrusion until shortly before, but she felt an intense desire not to have a cock again, but to have someone else's cock inside her.
One hand moved down from her breasts to find the hard nub that had once been his penis. She carefully stroked it, and an intense jolt ran through her body in response. It felt pleasurable to the point of almost being too painful! Besides, she realized, this wasn't where a guy's cock would fuck her. She felt it further down.
Her hand reached down past her clit, and found the moist vaginal lips that had formed from her scrotum. She felt an unfamiliar emptiness and urge to have it filled from that point. Her finger slowly eased inside her, and her eyes squeezed shut as a keening moan fell from her lips.
Ty's mind went blank as rational thoughts gave way to intense sexual fantasies. Any pretense of simply exploring her body had faded now, she was just masturbating. And the fantasies were just amazing- she imagined a handsome boy with toned muscles fucking her firmly, his hand playing with her breast. She imagined him dirty talking to her, saying how beautiful she was and how good her pussy felt. Sometimes he'd even call Ty 'he' or 'boy' and then correct himself to 'she' or 'girl', or purposely thrust so that his balls slapped her thighs.
Before long, Ty felt herself convulse as her first female orgasm took hold. Her nipples seemed to pulse against her fingers and her pussy clenched tightly around its intrusion, and the imaginary boy in her fantasy came inside her hard.
Leaning against the mirror to keep upright, Ty slowly came back down from the high, and as she did, she wondered what to do next...
