A gymnasium for just two people

A high school dare spirals into a blush-drenched standoff when a boy asks his classmate Naoko to show him her panties, and she counters that he'd better bare himself first. Inside the gym storage room, he exposes his penis without hesitation, but shy Naoko stalls, only surrendering her bloomers after a flustered plea—left standing in just her bra and panties, heart going ba-dump, as she covers her chest under his stare. The tension breaks with him stroking himself right in front of her wide eyes, finishing just as the school bell warns that break time is over.
