my ex boyfriend stayed over one night, and we went back to his place early the next morning cause they were moving and i was helping pack. he didnt have time to get changed so he went in his pyjamas. his mum met as the door and just looked at him and he said "her mum made us sleep in different rooms" and she said "i dont mind as long as youre using protection" at the time it was shame cause his mum is a bit older than most mums.
and my current boyfriend and i had like the house to ourselves one evening and we had had sex and fell asleep under the cover naked. after i went home the next morning his mum goes "i came in to say good night and tell you i was home and all i could see was your hairy arse hanging out the edge of the bed! dont turn my house into a sex spot."
another time theyd gone out and come home while we were at it and we wer rushing to put clothes on and i only had a shirt on and was lying under his doona cause theyd walked in the house, and his mum and 13 yr old bro walked in with him in a pair of shorts both of us puffing and redfaced and me covering myself up cause i still didnt have a bra on which was rather noticable........
other than those experiences, nothing has been bad or funny, and they were just memorbale not even bad
