The protagonist has a girlfriend and to say goodbye to his girlfriend they go to the beach and decide to make love there, when they are about to start they see another couple on the rocks, an older man and a young girl having sex. The days go by and the protagonist leaves and arrives at a house where there is a beautiful milf and introduces himself. The milf's husband also arrives and realizes that the man is the same person who was on the beach with another person and reasons that I was being unfaithful to him. The protagonist stays to live in a room next to the house. I've been looking for it for months and I can't find it, I would appreciate any help please.
