Omg. Haven't thought about this for years.
In my teens, the guy I was shagging had just moved into his own place, barely had anything and what he did have was cheap rubbish (as most of us had when you first leave home).
Anyway, he had a bed with a flimsy wooden frame, was fucking him missionary and his head kept bashing into the wall, which gave us both a good chuckle and we decided to change position before he got a concussion. Moved back towards the end of the bed, got him on all fours and we're going at it hard and rough when the one leg of the bed breaks, we both tumble off the bed onto the floor, he goes into the mirror, glass everywhere, utter chaos & he just lies there, looks at me and goes - "well, i guess we should move this to the lounge."
Both of us just burst out laughing, took a shower to make sure we didn't have glass on us, had an epic shag and then cleaned up the glass and fixed the poor lads bed.
One other funny story was with an ex boyfriend. He lived with his brother who was out for the day. He took a shower, walked into the lounge naked and obviously, i immediately started sucking him off.
Having a lovely time until we suddenly hear his brothers key in the door. Im dressed, so im fine, but my boyfriend freaks out, tries to run to the bedroom before his brother gets in the door and he runs face-first into the door frame! Had a massive cut on his eyebrow and lots of bruising. He didn't think it was funny, but watching it happen was hilarious
