In a shared dorm room, two innocent-looking bl boys,宗介 and 真琴, find themselves alone and idle. 真琴, drawn to宗介's casual wear, tries on his loose-fitting jockstrap, feeling a strange thrill.宗介, noticing the bulge in 真琴's shorts, can't help but stare, his own cock stirring. Their eyes meet, and a silent understanding passes between them. They're just getting started.
