When i first got into zoo my lover was my grandpa's great dane. Due to our housing situation I was on the couch in the living room.
I was a night owl so I could wait until everyone was asleep.
The layout of the house was front door to the east leading into the living room/ kitchen area, the back door was at the back of the kitchen/ clothes washing area, and there was a South hallway joining all the rooms and the bathroom
In other words if anyone wanted a late night snack they would come in from the hallway, have a full view of my futon and have to cut across to the fridge on the north side of the house.
Well one day I'm bent over the couch, facing east, getting railed from behind and I hear a toilet flush. I panic and try to get him off me but he's going at it and won't stop.
I hear foot steps coming down the hall and while I can't see who it is because I was getting fucked by a horse dog, I know that someone from my family is there as the foot steps just stopped at the hallway entrance.
There was about a 5 second pause before I heard them walk back up the hall, and one of the doors close.
This was maybe 12 years ago and no one in my family has ever said anything, but I suspect it was my uncle and if I'm right then he took that moment to his grave
