Well, with looks like the third, uglier Neville brother I've never been asked to stay for hours, met the girl's parents, move in and started paying rent like you guys (do you just not leave until you're asked? usually I've gotta dash afterwards anyway before OH gets suspicious. 100% there's a lot of SPs out there just thinking "when is this cunt going to leave?")
For me it's when I blow my load in a girl's mouth and she swallows the lot.
