"I'll make my own world." Ty grabbed the part of his mind that allowed all this to happen, and made an alternate world for himself.
It was 50 times as big as Earth. It had billions of little people waiting to serve him in any way, shape, or form. They were all men.
G. Ty created the most erotic gay movie ever, and watched it. He jacked off, sitting on his huge ass, moving his hand up and down, until cum went fountaining out.
"Ooh, that felt soo good." Ty said. Just then, a very attractive young man, about his age, whom he'd named Jay, walked by. Ty seized the moment to make Jay almost as big as himself; not AS big, but ALMOST.
Ty created a door, which lead to a room with a bed and all the giant sex toys you could imagine. Jay leaned over the bed (as he was expecting this), and Ty, obliging, inserted his uber-cock into Jay's ass. He slid in and out. Ty'd never had such pleasure before, nor had Jay. But it still wasn't enough.
Ty slid out for a last time. He shrunk Jay to almost the size of his cock head, and then...
He started to mature. His cock got larger, he filled out even more, and was hotter than ever. Ty picked up Jay and put him on his penis. He had Jay slide back and forth on top of his giant penis. It felt good for both of them. Jay started moaning, and finally released cum all over the cock, but Ty urged him on more and more. As this happened Ty jacked off himself. He loved seeing this small man enjoy himself on his cock.
MEANWHILE....
Dustin stood up. His brother was a giant now. GREAT. But he was still the sexy man before his brother had grown, and called up his girlfriend. She came over.
They walked downstairs to the couch (Dust had pants and a t-shirt on, but they were too tight!). He pulled it out, revealing a sleeper-sofa. His gal was still in awe of his sexiness. They both started kissing and stripping the other, going faster and getting more and more intense.
They fell onto the bed and Dustin stuck his cock into his girlfriend's womanhood. In and out he went until he ejaculated. By now they were both at orgasm top. Dustin slid out, kissed her, and they silently put their clothes back on, and his honey left.
