After an exhausting day of sex, Ty and his boyfriend lay in bed next to each other, panting and staring at the ceiling. Ty's smaller body was resting his head on the crease between Nick's vast pec and striated shoulders. Neither had known pleasure like this before, and it had blown their minds.
Knowing they'd go to school tomorrow, they slept for the night and went to school in the morning, Ty having conjured up some clothes for Nick. He also ensured that everyone thought things were as they always had been.
Upon arriving at school, it became apparent that Nick was not only far larger than his friend, but far larger than any other kid there. Three or four kids at a time would feel him flex his bicep, its hard, shifting mass titillating all their hands.
"I'll have to meet you at lunch, okay, Nick?" Nick nodded as he put down a kid hanging from his forearm, his shoulder tenting impressively.
Going their separate ways for a bit, Ty finished his PE class with a free. He and a friend dawdled in the locker room, chatting until they were the last ones there. Gavin always changed back slowly, but Ty was already familiar with him: he liked working out, and had built a little bit of mass since the beginning of the year, but kept a lot of fat, making him look far less impressive.
"You're pretty big, Gavin."
"Yeah, man. You should work out with me," replied Gavin, totally unable to take his eyes off Ty's astoundingly flat crotch. Ty didn't mind, he was still in his socks and women's underwear.
"Let me see..." Ty trailed off as he stepped forward and felt up Gavin's left pec. Gavin was surprised, but let it happen. Ty could definitely feel a hard, round pec under the fat. "Mmm. I can help you with that."
Gavin looked surprised. "You can?" He took in all of Ty now, the shorter boy who was skinnier than Gavin's budding meatiness, and who had no penis. Despite Ty's apparent fragility, he stood like he had all the power in the world.
"Yup." Ty's excited smile returned, which the clueless boy mirrored.
