[MF]/[MMF] Looking for wife sharing story.

I’m looking for a story that I read here (I think), it was about a guy who’s girlfriend(?) falls asleep before they can finish having sex. He then asks his friend/roommate/whatever if he can have sex with his wife(?). The friend reluctantly agrees. I think the friend may have watched or joined in, but I’m not sure.
