Josie felt arousal swimming through her as she stared at her naked form. She slowly realized something had changed when she feminized mentally. Now she felt attracted to boys. Thinking about her old body didn't feel neutral like it had when she'd had a male body- now it felt foreign and different. Now a penis wasn't something he had, but something her body was meant to accommodate. Vaginal juices were running from her moist slit.
She knew she wanted to do something about this. "My cute boyfriend is visiting for the day," she wished. Sure enough, a moment later a naked young man shimmered into existence and cuddled her from behind, giggling as he started to kiss her neck. She bit her lip as she felt his hardness rub against her butt and back. "Want something, babe?" she breathed.
"Yeah," he replied. "You." His hands reached up to her breasts and cupped them, and she exhaled eagerly as her softness met his firmness. When he pinched her nipples, an ache of desire shot through her.
She soon grabbed at his wrist and purred, "Wanna take this to the bed?" He nodded and she moved to it, lying down and allowing him to get atop her. His large, firm chest and long thick penis were the most enticing thing she'd ever seen. As he positioned himself, his large shaft, its head shiny and wet with pre, sat on her stomach. The idea of that being inside her made her practically shiver with anticipation.
He kissed her softly, and then whispered, "Ready?" She nodded, and he moved his shaft down and slowly pushed his cock inside her. Once it had gone all the way inside her, he reached down and carefully played with her chest again to ensure she was comfortable.
Josie was spellbound by how divorced she felt from her old sex. This all felt so different, and so much better, than being a boy had felt. Having breasts to be massaged felt so pleasurable. Having a vagina to be fucked felt so pleasurable. Having a boy against her felt so pleasurable.
The boy carefully started to move, his shaft pulling back and his hips thrusting forward faster and faster, a repeated instinctive motion pistoning in and out of her eagerly. Josie clung to him, making sure her hole was as warm and moist and inviting as possible, and in return his head rubbed against the sensitive points inside her, stimulating her G-spot and making her shake with pleasure.
Eventually she came, and her head went blank. Everything seemed to vanish except the pleasure and the sensations from her and her boyfriend's lovemaking.
Just as she started to come down from the high, she heard her lover groan, "I'm gonna- I'm gonna-!", and felt his cock spasm inside her, warm semen flowing inside her in thick bursts. The fluid's touch inside her brought her right back into the throes of orgasm, and she instinctively clung to him to ensure not a single drop went anywhere but inside her.
He lay atop her and they cuddled breathlessly as their peaks subsided slowly...
