Lesbian couple Arisa and Miyu. On a Friday night, the two remain in the office after overtime work. Arisa reaches her limit and makes a move on Miyu, but Miyu hesitates, saying it's embarrassing to do anything here. However, Arisa can no longer hold back and begs Miyu for perverted play. In the late-night office, the two exchange saliva-drenched tongues, passionately kissing and licking each other's faces thoroughly, their desire escalating intensely.
