>>2512047The closest that I can think of to an anime like that would be Miss Caretaker of Sunohara Sou. It doesn't have too much going on being a slice of life anime, but it's not hentai and the central focus is on the young boy and the older woman (a caretaker). Not sure what specifics you are looking for though, so I can only tell you to look it up and see if it's in your interest.
