Uchino joins the student council to get closer to the admired president Megumi Hokura. While working in the council room, he notices her movements resembling masturbation but stays silent out of frustration. When her documents fall and he bends to pick them up, he encounters a lewd sight that escalates the situation. (Note: Some sources reference different scenarios like swimming club training under Captain Kurotaki or other club-based encounters; the series features multiple short, loosely connected school-themed stories involving uniforms and erotic tension.)
