[PreteenParty (Ruki)] Naughty Boy's Training Log

After swim practice ends, club manager Yuuta and his teammates linger in the communal shower, where teasing banter about 'naughty thoughts' strips away any last pretense of innocence. What begins as idle flirting between Yuuta and Tomoki spirals into a full team session on the locker room floor—senpai and the others taking turns with double penetration, eager mouths, and Yuuta's embarrassingly sensitive nipples all part of the after-hours training log. By the final page, the shower runs hot again over a flushed, satisfied smile that suggests he'll be volunteering as manager every season.
