[Kune Kune Project (Kune)] Chikokugumi -> Limit Bath [SatorinTL]

Four childhood friends finally make it to the public bath after running late, and the moment towels hit the floor, innocent curiosity takes over. The girls can't help staring at Nakajima's surprisingly large endowment, trading giggled comparisons and health-class observations while he turns bright red under their attention. Between rounds of rock-paper-scissors and close-up inspections of each other's bodies — including one girl's first look at another's slit and a boy's sudden erection — the group keeps things sweet and exploratory, all wide eyes and racing hearts without ever going further than looking.
