Cuck, what do you like to do while your wife's beeing fucked?

One time, my first wife came home from a date, and he drove her into our driveway and turned the engine off. I watched the car through our living room window for a good 20 minutes as it very slightly swayed. I could just make out the shadow of Mark sitting in the driver's seat, smoking a cigarette. He looked to be all alone in the car until I saw a female shadowa ppear in the passenger-side window, pull down the visor, and seem to put on lipstick in the mirror. The passenger-side door opened, and my wife dot out. Mark started the engine, and backed out of the driveway. When she came in, I asked her what the hell that was. She said that she didn't think that I'd still be up. I asked her if she just blew him in the driveway, in public. She smiled and told me that I was cute for being jealous, "It's just sex, Jack. Get over it. I'd kiss you, but I taste like Mark."
This is a great story. As my wife would say, "bull should always leave with empty balls." We had a similar situation: he dropped her off at home after work and asked her to give him a blowjob in the car. We were having dinner at home at the time, and she told me everything in detail. We had passionate sex that evening.
 
try licking his balls at this moment, it makes me scream when I cum in his wife.
I stay away from that. Once I will suck a cock to know how it feels when it grows in my mouth, but further as well my wife as I are not into the bi stuff. It also doesn't turn her on, and the kick for me is seeing to get her turned on by another guy. And of course when she's hot for it they should please each other.
