Kanade, a married woman, was busy trying to conceive with her husband through passionate sex. One day, her difficult mother-in-law, Hitomi Enjo, stayed at their home... Despite being pressured by her sexually aggressive husband, she couldn't have sex due to her mother-in-law's presence and resorted to quiet handjobs and 69, culminating in a mouthful of cum. It turns out that her mother-in-law and husband had a long-standing physical relationship, engaging in anal licking 69 and vulgar crab riding sex when alone. Upon witnessing this scene, Kanade was confused but was soon drawn into a incestuous 3P with her mother-in-law, falling into the pleasure of vulgar sexual intercourse.
