Theres a hentai doujin that I can't for the life of me remember what it's called.
Starts off with brother the washing machine sniffing sisters panties. She catches him and makes fun of him for a bit but then makes out with him. They fuck and then take a bath. Fuck again, and the sister asks about if they have a kid and the brother claims he can mow yards or something.
And of course, I find it as soon as I post this. Took me a week.
