Swimming Club Equipment: Minase Suzuka 2

Swimming club member Minase Suzuka is blackmailed by coach Goto Ryuji with fabricated photos and forced into absolute sexual obedience as a 'tool' so the images will not be sent to her boyfriend. The coach locks her for eight hours in a men's locker-room tool cabinet, cuffed, ring-gagged, and fitted with vibrators; when the door opens, club members Nakayama, Ooishi, and first-year Terada find her, stop her escape with a remote vibrator, and treat her as the coach's performance 'reward.' Citing rules against unpermitted holes, filming, and violence, they grope her breasts until Terada cannot hold back, face-fucks her through the ring gag, and ejaculates, after which the three resolve to keep using her as a sex slave/tool. After the members and coach finish using her, a member admits oral-only use got boring but that trying it himself made him understand the coach's fetish; Suzuka is left bound on a table in her competition swimsuit and boots, ring-gagged, with multiple vibrators still running hard and remotes discarded nearby. The members tell her she must aim for national first place and that worse grades mean other people will get turns, ordering her to work harder, and the work closes on her still blindfolded, ring-gagged, collared, and labeled swimming-club equipment.
