Walking outside and leaving the now enormous Dustin behind, Ty walked looking for another person to play with. Eventually he spotted a boy, around 12 if he had to guess. He was playing on the play structure, but Ty wished for the boy to have the sudden urge to pee really bad.
The boy walked into the nearest restroom, and Ty waited outside. Right as he walked back out, Ty walked into him.
"Oops! Sorry didn't see you there- hey, want to play a card game?" Ty asked, smiling innocently. Slightly confused, the boy, who's name was Sam, agreed and asked what the game was. "Draw five cards" Ty said, grinning.
The boy flipped over the first card. 2 of spades. Almost immediately the boy let out a small groan and Ty saw the front of the boy's shorts bulge outwards just a little.
Four more cards, Ty thought.
The boy flipped over the second card. 5 of hearts. The boy's muscles inflated as 50 pounds of muscle was added to his frame instantly. He looked like a teenage bodybuilder! Amusingly, he was still shorter than Ty, so his muscles really stood out despite the fairly small amount added.
Flipping over the third card, the boy shot up a couple inches taller, coming face to face with Ty. Ty peeked at the card. 3 of diamonds. He grinned. "Two more".
The fourth card was a jack of diamonds. Immediately the boy shot up again, from Ty's height of 5'6 to 10 inches taller at 6'4". The boy's clothes looked horribly small on his figure now. At least his muscles had made it so that the boy wasn't skinny.
One last card, Ty watched as the boy flipped it over with anticipation. Seven of spades. Again the boy's shorts bulged out as his cock grew more than a half a foot longer. Slightly confused and dazed, the boy walked back to the play structure. Ty just laughed.
