Just imagining his own junk crammed into girl underwear was enough to make Eli cringe in empathy. And Denver was adult sized, which probably meant that her, um, parts, were adult sized too. And she was wearing teen girl underwear.
"I miss mine," Eli said sadly. "Especially right now, I um... I hafta pee." Right now he was cursing himself for having drank that two-liter of Mountain Dew last night. Slinking into a stall feeling totally mortified, Eli pulled the door shut behind him. "Don't go anywhere," he called to Denver. "Girl plumbing is complicated and I might need... instruction." It seemed pretty simple- sit, pee, wipe and go- but maybe there was another step in there. After all, girls were always in the bathroom for forever, maybe they had a routine.
