Imagine having your mouth rented out by your wife/girlfriend to pleasure cocks of her choosing.....
One night, doing a threesome, after I sucked our friend's cock for awhile I positioned it at the entrance to my wife's pussy. He started pounding away while I moved next to my wife to offer my cock to her mouth. She sucked on me for awhile until he pulled my cock away and put it in his mouth. She got so hot from watching this that her pussy creamed his cock with white juice. My wife freely offers my cock to any hot guy who wants to suck it as long as she gets to watch.
