Chris was an average high school guy, and he'd been asked to babysit his neighbors kid. Not like Troy was too much trouble, but he tended to get real muddy real quick, and that meant lots of baths.
"Come on Troy!" Chris groaned "Just get in the tub!" Troy just laughed and ran away from him, content with staying muddy and dirty. "I'll give you some ice cream later!" Chris promised.
That was enough to get Troy to comply enough to get in the tub, and begin splashing. Chris was having a hard enough time keeping the bathroom dry as it was, now he was soaking wet.
"Chris?" Troy asked "Why you pway with girls?"
Chris sat there for a moment, for some reason, his brain was working slower, and he couldn't think of a reason.
"Girls gots cooties." Troy said matter of factly.
Chris just nodded numbly, his brain smoothing out slowly, when he noticed something. "You boy!"
Troy just giggled and nodded, standing up out of the water and pointing at his groin. "I has a pee-pee. You's a boy, so you gots one too."
Chris nodded, and looked at Troy, standing in the tub in his naked glory.
"You're clothes is wet. Taked dem off, and let 'em dry." Troy suggested helpfully.
Chris thought about it for a minute, and decided to do it, yanking his pants and boxers off, exposing his own pee-pee. And then taking off his shirt, he was nakie.
"We have I've cream now?" Troy asked.
"Uh-huh". Chris responded, and ran downstairs giggling, before opening the fridge and pulling out the ice cream tub. Troy followed suit, and the two sat on the kitchen floor nakie eating the ice cream.
Chris saw the sprinkler out back, and immediately wanted to go play in it. "Let's go pway!" He yelled, getting up, before a wave of pleasure from the virus began its final work, his penis suddenly standing at full attention, which Troy noticed.
"You pee-pee gots big." He said shyly.
Chris said nothing as his pee-pee began to become flaccid again, and the two went outside to play.
