It's been a week since my daughter-in-law went on a long business trip. A lustful mother-in-law comes to Daisuke, who is having trouble doing housework. The breasts with their outstanding weight vibrating every time they move are irresistible. Daisuke, wanting to massage his very plump breasts, somehow secretly filmed his mother-in-law taking a shower but was caught red-handed at the last minute. However, instead of getting angry, my mother-in-law seduced me with masturbation.
