First of all, I do not now if a post like this is allowed, couldn’t find any rule or guideline!
I’m looking for a story where a guy is on a sleepover and is asleep, as a woman comes in his room (tipsy or drunk) and he initially thinks she just misplaced the room, but they end up having sex. The next morning they have a talk and she states something like “a woman can feel when she had sex, and since you’re the only man in the house it must have been you”. Can remember it clearly, but can’t find it anymore…
