NEM-044 Accidentally cheating with a super slutty mother-in-law

Sachiko, the mother-in-law, argued with her husband and entered her daughter's and her husband's house. I fell asleep drinking and listening to my daughter's complaints. The son-in-law carried Sachiko into the bedroom and took care of his mother-in-law's plump body. Sachiko half-jokingly and half-seriously seduced her son-in-law, saying, Let me take off my clothes. The son-in-law got an erection when he saw his breasts without a bra, but Sachiko who noticed it became excited, and then he began to frequently seduce him while teasing him. One day, when my daughter-in-law went to a girls' party and was alone, my son-in-law and mother-in-law ended up overlapping each other.
