Woke up to the sound of sex after a party, went to wake my wife so we could laugh at it but when I reached for her she wasn't sleeping next to me. As I approached the top of the stairs I realized it was her and a good friend of mine. You can hear her faintly say slow down or stop, so they must have been doing anal, something she doesn't do with me because she says it hurts. Which I now realize is a lie because I know for a fact my friend's dick is much bigger than mine.
