THICC and Mature housewife Aya Misaki strains her lower back one day while taking out the garbage from her apartment. Her neighbor Shingo asks her to let him massage it as practice for his upcoming Masseur practical exam. Enjoying the results, Aya starts letting out moans of pleasure during the session, which leads to them going at it.

Addicted to Shingo's technique, but confused about the feelings for him growing inside her, Aya struggles against her desires for the man who has touched her in ways not even her husband has done before.
