The building - Milf at each floor

[Yukina]

A group of friends (2 normally but can be 3) discuss of what to do with their summer holiday. They happen to encounter somewhere an aphrodisiac recipe and decide to test it first on one of their relative, being the stepmother of one of them. And as it is a great success, want to do it on every woman on the building, each of one being hot and lonely housewives.
