A beautician uses Brazilian wax to remove hair from a female client's intimate area, leaving her pussy completely smooth, then lasciviously toys with her bare slit, luring her into lesbian desire. Kitagawa Riko visits the clinic for the first time, planning to get ready for a beach trip with her boyfriend, but gradually becomes ensnared in a lesbian affair. After being fully waxed, she's shocked to see regular client Kirishima-san, who's already involved in a lesbian relationship, casually playing with her bare pussy and penetrating her with a double-headed dildo as usual. On her second visit, Kitagawa undergoes O-line treatment. While the therapist massages her buttocks, she's suddenly kissed. Despite having a boyfriend, she's told this isn't cheating—and soon finds herself climaxing with a vibrator, drawn deeper into forbidden pleasure.
