In her youth, my wife had a pretty close knit group of friends. Good mix of guys and girls, and they were pretty open with each other about most things (according to her). So when one of the guys they all thought was cute got dumped by his girlfriend, wifey and one of the other girls hatched a plan to cheer him up.
She didn't go into too much detail about the planning part, but was excited to get to the action. Step one, they got him into the bedroom and handcuffed him to the headboard. Step two, her and the other girl took turns stripping for their friend, then sat just out of his reach and began making out. Once they had each other good and worked up, they took turns sitting on his lap, and sliding on and off of his cock until he just couldn't take it anymore and ended up cumming in her.
