Close friends and office coworkers Tenma Yui and Onodera Mai head to a pool after work and swim in their office clothes. Their soaked suits turn transparent, exposing the lingerie underneath and leaving both women turned on. After wearing themselves out in the pool, they have a few drinks and slip into tipsy lesbian sex packed with sloppy deep kisses. They keep making out, cover each other in sticky slime, and happily fool around together through the end.
