Sluts love to suck cock. They think it gives them some sort of power over a man. That's the kind of idea you need to train out of your slave. Her job, her only reason for being, is to swallow as much of your jizz as possible. She needs to learn to suck you the way you want. And in a way that's enjoyable to the men you share her with. I pull my slut wife's eager mouth down on my cock as often as possible. I force her to try new things. I make her suck and lick me for hours on end. And when I'm at work, she sucks a dildo and records her efforts on the webcam, so I can judge her technique.

But even all that practice isn't enough. When I finally give this bitch to my friends and fellow Masters, I don't want her to embarrass me with her sloppy cocksucking. So every few weeks, we visit a nearby adult bookstore. It's one of the old kind, with porn rags in the front and video movie booths in the back. Ten bucks gets you about an hours worth of the nastiest videos you can find. I parade her in the front door, dressed in a tight white halter top, a short black leather skirt, black stockings and leather boots. As we head to the back, I don't even have to tell the other patrons that she's going to be working the holes. They can tell just by looking at her slutwear.

The booths are big enough for two, though there's a sign warning against this. We always ignore it. The manager knows that a slutty cocksucking woman will draw bigger crowds and more money. The door to the booth won't close unless the video is running, so we always drop ten bucks in right away. I pick the movie. Usually something where five or six studs are gangbanging some poor slut. Lots of abuse and cum shots.

Once inside my slutwife pulls off her top and skirt, so her tits and pussy are bare and available. Then she pays homage to my cock, kneeling on the sticky, filthy floor to kiss my crotch and declare her loyalty to her master. By this time, one or more of the gloryholes has been filled. It's time for her to go to work.

She's allowed to do whatever it takes to get every cock to shoot its milky load on her, except for letting them penetrate her. She'll stuff her tit through the hole so the man can suck on her ripe nipples. She'll stand near it so he can push his hand through and fondle her bare, wet cunt. She'll give a protruding cock a tit fuck. Or kiss his dirty bare feet if that's what gets him off. Mostly, though, she sucks their cocks. She bathes the big black cocks with her tongue. She licks the old man's scraggly balls. She deepthroats the nervous teen. She hoovers the desperate gay. She lets the sweaty, lonely men fuck her waiting mouth.

And she takes their cum like an addict getting a fix. Sometimes I'll have her aim their load right on her face. Sometimes their jizz juices covers her tits. The next one might hose her pussy patch. But usually she takes it right in her mouth. And there's none of this porn movie spit it out stuff. On my orders she swallows every drop. I won't let her leave until she's sucked out a dozen loads. Many times, she does twice that. At the end of the night, she's usually slathered in jizz. It drips from her hair. It congeals on her tits. It covers her face. 

If she's done a good job, she gets her reward: we leave by the back entrance, where far fewer witness her cum covered humiliation. If, though, I feel she hasn't done her best, she leaves through the front, walking out past all the horny men leafing through gangbang magazines, watching her with eyes that say exactly what they'd want to do to her. And sometimes saying it out loud. All she can do is suffer the stares and comments, her white top plastered against her skin by globs of cum, her tits and nipples clearly visible to everyone. And if she licks her lips out of nervousness, that only reminds her of her gloryhole training - her lips are still covered in sticky, salty cum.
