55-year-old Akie Imagawa lives with her husband and son. She hasn't had sex with her husband in years—her marriage has become completely sexless. But I'm still young inside, and there are nights when my body aches for release. My husband won't satisfy me, so I'm left to masturbate alone, overwhelmed by my own pent-up desires. One day, acting on impulse, I entered my son's room and caught him masturbating. Seeing his erect, throbbing cock sent a shocking jolt through my entire body. In that instant, the loneliness and emptiness I'd been carrying suddenly cut deep into my heart, sharper than ever before.
