Mother-in-Law Temptation

When Shizuya catches his wife's stepmom touching herself one night, she tells him her fingers aren't enough to satisfy her and begs for his cock too. At first she promises not to put it inside, just rubbing her clit against his shaft till she cums from sumata, but before long, this busty MILF demands his cum and secretly starts to fuck him all over the house! They won't be able to keep their sex games secret from his wife, Remi, forever, but is there a way for all three of them to be happy?
