My friend's really prudish Mam walked in on us reading out one of those Buzzfeed lists of bad sex experiences.
The particular one she walked in on was about a young couple experimenting with anal beads and the girl had them in, and asked the guy to take them out so he YANKED THEM OUT in one quick tug!
She literally walked in on "... pulled the beads out of my arse as if he was starting a chainsaw"
She was disgusted it was hilarious
