A masseuse was dispatched to touch her private parts until she couldn't bear the pleasure and was then sexually assaulted. (Yayoi Mizuki, DASS-409)

Mizuki, a working professional for a year, and Kenichi are planning to get married and live together next year. Exhausted from her working life, Mizuki calls a masseur because of back pain. Her boyfriend, busy with work, doesn't listen to Mizuki's complaints about her weakness and foolishness throughout her year as a working professional. However, under Kawamura's gentle touch, Mizuki reveals her own weakness and foolishness. Mizuki confesses to Kawamura, but during the massage, her sensitive areas are massaged, and she feels pleasure. Although she knows she shouldn't, she is still aroused by the touch and enjoys the process. Unconsciously, after countless massages, Mizuki is close to orgasm when the timer rings. "Want to extend it?"
