Adam felt Stan's hard, smooth pecs rubbing against his back and looked at the big arms, pumping his own giant dick up and down. "You're really liking this, aren't
you? Adam asked Stan. He could feel his big friend nodding.
"You really love being big," Adam said. More a statement now than a question. "I bet the more you fuck, the bigger you get," Adam suggested. He saw the change
first in Stan's arms and hands... they were getting a little bigger with each slap of his ass. He loved the feel of Stan, slowly expanding behind him.
Adam watched as his pre-cum started to trickle up his dick. It shrank slightly, an artifact of Mario's earlier idea. Adam changed his mind about that. "Those strong
hands are enough to make anybody's dick grow, I bet" he said to Stan. Immediately the shrinking in Adam's dick stopped, and it began to regain its lost size.
Adam looked at Mario, who had stabilized at a little less than five feet tall. He knew Mario liked big guys, but he didn't realize Mario had been willing to shrink
himself over it. Stan was already up to about 6' 7", and with Stan's tiny dick, they were soon going to be perfect for each other.
Adam started pumping Stan up. "You want me to cum at the same time you do? You ready?" Stan grunted. "Aim my dick at this little guy and I'll keep shooting
until you stop stroking it. 3 - 2 - 1 - go"
Adam thought he felt something happen with Stan's tiny prick, but then all other thoughts were swept aside as his cum cannon unloaded on Mario. It was incredible
as he felt his dick squirting load after load.
