Over the past 3 days I have been trying to find something worthy of this thread, but the only thing I stumbled across that came close (pardon the pun) involved - you guessed it - porn.
It's pretty great, it's a guy banging some girl with an older woman watching, and when he goes for the money shot, as soon as the first, erm, squirt, is fired off, the older woman's like "OOOHH!" all excited-like.
This should serve as an indicator of exactly how much I need to move out of my mother's house and get a life, but hey, it's funny while it lasts.
