I was with my partner at their parents’ house years ago and we were naked and had tails in our asses. I was changing the input on the TV from their bed, ass towards the door, when their dad came in. Excitedly, about to tell us about something he was psyched about like “HEY SO I JUS—“
Immediately backed out and closed the door softly. We came out ten minutes later, washed our hands, and walked into the living room where he was reading a book. He says “how’s it going!” and we’re like “Great!” and he goes back to reading.
