[sakidesu] Minna de Shūgaku Ryokō-hen | School Trip Arc With Everyone

A male student is summoned to room 505 and pulled into a teasing, escalating group encounter with a roomful of large-breasted women, whose attention shifts between playful boasting, breast-focused teasing, and competitive urgency. An energy-drink interlude and references to the previous night keep the momentum building as the girls draw him deeper into their orbit, with the harem dynamic centered on one overwhelmed sole male. The finale pivots into a cosplay celebration and a double-digit tally, promising a hectic, body-conscious school-trip fantasy where everyone joins the fun.
