HBAD-409 I was driven mad by my father-in-law, a masseur, with an oil massage ~ Yuri Osikawa

The house she married into was a chiropractic clinic, and at her father-in-law's behest, the bride helped out. Her husband neglected their marital life, so Yuri felt lonely inside and would masturbate to relieve it... Seeing this, her father-in-law could no longer suppress his lust, made her drink an aphrodisiac potion, and manipulated her body with oil massage. The bride's body responded, and she began to fall into carnal desire.
