story about 2 couples i cant find

[reconmx]

i read a story awhile back and never could remember the name. It started off with 2 cuples who were neighbors. one couple asked the other to watch their house. the husband did and while checking on the house he found vidoes of the couples house he was watching, vids of the wife getting fucked by other guys in a hidden cam. in the end the couple suduces the guy and his wife and they all surprize the guy for his birhtday by letting the couple fuck his wife. kinda confusing i know but i cant word it any better
