Is it normal to want to put superglue in lube?
My friend's girlfriend is staying with us at the moment and they were having sex all last night. It really annoyed me because I couldn't sleep properly, so here's what I did. When they were out at the movies, I got their lube and emptied it all into the sink, then filled up the bottle with superglue. The superglue looks exactly the same as the lube does and has the same sort of consistency too, so they will hopefully fall for it.
Is this a cool prank or am I going to be in a load of shit?
