M970G06 ありふれた日常がちょっとしたきっかけで肉欲性交に発展する背徳物語。

A beautiful married woman with big breasts who lives with her husband and father-in-law, who tend to travel on business trips and is busy with work. I'm on a business trip today and my father-in-law and I'm together. The usual daily routine of massage develops into carnal sexual intercourse at the slightest trigger. The father-in-law with a side fetish can't control his and gives his armpit licking massage to his sleeveless daughter-in-law. My wife, who is busy with work and doesn't always care, feels it and falls into carnal sex!
