have you ever had an awkward encounter with your partners parents?

Me and my ex had sex a lot like and it was always at his house, anyway so this one time we started off and he went down on me and we hear this knock at the door and his mom barges in asking for the wifi code. I'm really embarrassed by this point because I'm half way through. So he pops his head back up and starts shouting at his mom to get out because well in the nicest way we are both naked? And she's still wondering round the room asking about this wifi code! So he gets dressed and starts looking for it too while I'm sat naked on the bed and his step dad walks in too. I felt it was a really uncomfortable situation to be in and I couldn't look her in the eye for a week
