Fortunately for Ty, Eileen was in just as much of a confused and aroused state. He got up from his chair and came to sit next to Ty on the couch, and asked shyly, "Ty, can I try something? If you're not OK with it I totally get it."
"Go on," Ty agreed. The older man put his large hands on Ty's cheeks, leaned in and kissed him. Ty kissed back more eagerly than he expected to, and felt Eileen's hands move to his back. He shifted his arms to allow the man to pull up his T-shirt, and then removed his shorts and boxers, breathing heavily as he broke the kiss to take his T-shirt off and get completely naked.
"You're so handsome," Eileen told Ty in his deep voice, just as sultry as when he'd been a woman. "I really wanna fuck you. My body can't help it."
"It's OK, I understand," Ty said sweetly. "It must be weird to be a man, but I think you're still really hot. I think... I think I'd like you to fuck me."
"Ty, you're the sweetest," Eileen beamed, and he kissed the boy on his forehead before laying him down, getting himself in position.
"Just let me do one thing first," Ty giggled. He wished for his ass to be lubed and stretched enough for Eileen to comfortably fit inside him, and felt his tight hole seem to loosen up and liquid accumulate around it. Tantalised, Eileen pressed his head against Ty's opening and carefully pushed his length inside.
Ty groaned in surprise at the sensation of having his body filled up, and felt just as surprised by how arousing it felt to see Eileen's masculine body above him. His firm figure and muscular limbs were enticing as hell as the dark-skinned man pushed his sizeable shaft into Ty's more small and youthful body.
At last Eileen bottomed out, and Ty felt balls press against his ass. It felt so surreal and pleasurable and fuck, he loved it. Eileen's face cast spells on him too, as his eyes were screwed shut and he seemed to be fighting so hard to keep his responses to all this restrained. Once he opened them and looked at Ty, the smaller boy blushed and smiled at him. "This feels really nice, Eileen," he assured him.
"It does for me too," he agreed. "Is it OK if I move?" Ty nodded, and Eileen allowed her new male body's instincts to take over. He thrusted eagerly and rapidly into Ty's tight hole, and heard the boy moan appreciatively as his hard cock brushed against Eileen's stomach. It amazed him how different this felt to how sex had been for her as a woman- it was hard to describe, but as a woman there had been more power behind the sensation of sex, whereas as a man there was more power behind the motion of sex. It felt less intense to have his penis pleasured and moreso to fuck with it- it felt more instinctual and animal.
Since Ty was unused to any kind of sex besides masturbation, he wasn't able to last that long, and moaned eagerly as he came hard. His seed squirted messily onto his chest and seeing and feeling the other boy ejaculate pushed Eileen closer to his peak. He thrusted faster and more forcibly, rubbing against Ty's prostate and unknowingly prolonging his orgasm, until he hit his own limit. Grunting and panting, he shot his cum deep inside Ty's tight hole and his mind almost blanked out at the sensation of his first male orgasm.
For a few moments, the two of them remained connected, until Eileen slowly let himself withdraw, his shaft covered in thick white semen. Ty looked over their bodies with wonderment, hastily wished they'd recover from their orgasms and could fuck again, and wondered what they should do next...
