A few months ago I came back from a REALLY fun night out at the bars with some friends. Brought a few friends back to my place to crash. After hanging out for a while I put them all on couches, gave em blankets and went to sleep perfectly satisfied after a very fun evening. Went into my bedroom and fell asleep.
At about 3am I open an eye and see the girl that was on one of my couches in my room, closing the door from the inside. She walks over to my bed, slides underneath the covers and just goes to town.
I can't imagine that will ever happen to me again - I hardly knew the girl at all and certainly was not flirting with her that night. But man, that was a lot of fun.
