Lesbian couple Tugumi and Rumi deepen their sweet relationship every day. Today, they decide to try something a little different. Feeling their usual sex life has become monotonous, they start a game where the loser of rock-paper-scissors gets tickled, with the rule that neither can make a sound. The one who lets out a sound faces the punishment of being brought to orgasm by cunnilingus. A lesbian sex scene that feels less like typical AV, unfolding in a relaxed, natural atmosphere. The charm lies in its laid-back, authentic, and tender playfulness.
