NPH-108 - The stepdaughter, Nozomi Amura, is caught having an affair with her ex-boyfriend by her father-in-law, and then seduces the father-in-law as well.

The father-in-law witnesses the stepdaughter's affair with her ex-boyfriend. The stepdaughter gives a sly smile and demands, 'It's your fault my husband won't have sex with me, father-in-law, you take responsibility.' While the husband and mother-in-law are away, the frustrated stepdaughter's genitals are stimulated with a vibrator, and an erect penis is thrust deep into her throat in the kitchen. The aroused father-in-law and stepdaughter then move to another room and engage in sexual intercourse.
