Asked by her mother's friend to help deal with her masturbation urges, the long-absent mother is completely defeated by her young and incredibly handsome penis. (Okuda Saki SONE-795)

The son's sexual desire is unstoppable... escalating day by day, potentially turning him into a sex offender. The mother feels she's reached her limits with her son's abnormal libido... After much distress, she consults a friend (Okuda) she's known since kindergarten about sex education... Okuda has always publicly declared herself exceptionally knowledgeable about sex. She takes her son to Okuda's house. Faced with a mature female monkey unlike her mother, the son, a self-pleasuring monkey, suddenly goes into heat... Attacked by the son of her sexually monstrous friend... I'm almost dying from orgasm. Even if I ejaculate, I ejaculate, subjected to 12 rounds of sexual treatment by this erect, erotic little devil... I can't take it anymore.
