HBAD-409 - Driven crazy by my chiropractor father-in-law's oil massage: Yuuri Oikawa

The plot involves her being caught masturbating by her stepfather (played by Fumitaka Yoshimura, a regular in massage-themed AVs) and descending into pleasure through oil massages. The actor's massage technique is so convincing, it's like he actually took a course. She doesn't have sex during the first massage, but as she becomes unable to refuse her stepfather's harassment, she eventually ends up in a 3P with a customer. Her acting while receiving the massage was superb.
