I'll Squeeze You Between 2 [Chirumakuro]

Story

[High Jump!] "Keika," a member of the track and field club, was training hard because a competition was coming up. That was just a pretext, though—she had feelings for Makiyama, a fellow club member, and every night she masturbated while picturing him. One day, when he spoke to her during practice, she became so conscious of Makiyama that her crotch ached and she couldn't help but flee the spot. When Makiyama chased after her and stopped her, Keika turned around and kissed him on the lips, no longer able to hold back her feelings. [Ms. Mikako from the Sports Club] Tanabe, who attends a heated indoor pool, had feelings for the instructor "Mikako Makino." One day, having lost track of time absorbed in swimming, Tanabe returns to the locker room late and witnesses Mikako masturbating while sniffing the scent of her own panties. In exchange for keeping quiet about it, Mikako grants Tanabe's naughty requests.
