He wore a chastity cage and nothing more.</p><p>“Mitchell, I’d like you to meet my friend Emily, or Mistress Emily to you,” she said.</p><p>Mitchell looked up at the radiant blonde in a pair of jeans and a sweater and smiled. “It’s a pleasure to meet you, Mistress Emily.”</p><p>“It’s a pleasure to meet you as well, Mitchell,” she said while offering her hand.</p><p>Mitchell took it and offered a soft, submissive kiss. He was surprised and delighted when Mistress Emily then gently pressed her fingers into his mouth.</p><p>“It’s always nice to meet a well-trained submissive,” Mistress Emily said as her fingers pushed to the back of his throat over and over. “And it seems that Isabella has done a wonderful job of training you to serve her needs.”</p><p>Mitchell nodded at the two beautiful women standing above him.</p><p>“His training is very nearly complete,” Mistress Isabella said. “He eagerly consumes his own loads, sometimes masturbating to excess simply to swallow yet another thick, creamy prize from his balls. He adores licking the loads of other men off of my body and out of my pussy too.”</p><p>Mistress Emily smiled and pulled her fingers from Mitchell’s mouth. She wiped the saliva off on his face and said, “You were even willing to star in a porn video as a filthy cum eating cuckold, weren’t you?”</p><p>“Yes, mistress,” Mitchell replied. “It was a wonderful experience.”</p><p>“Will you be loaning him out again?” Mistress Emily asked her friend.</p><p>“Absolutely,” Mistress Isabella replied. “He’ll be starring in the sequel, in fact, and they’re bringing in four guys this time so Mitchell can fully embrace his position as a cum dumpster for superior men.”</p><p>Mitchell smiled as he imagined being a filthy cum slut in another porn video. He’d found the last shoot so thrilling.</p><p>“Look at that smile,” Mistress Emily said. “He really is a cum slut. Isabella, I’m so impressed. I guess that means he’s going to enjoy what we have in store for him today, isn’t he?”</p><p>Mistress Isabella laughed as she looked at Mitchell. “He certainly is. Aren’t you, cum slut?”</p><p>“Yes, mistress,” Mitchell replied.</p><p><br></p><p>Mitchell’s jaw ached and he hadn’t even finished the first blowjob. He was on his knees between the legs of the man that would be fucking Mistress Isabella and he’d been assigned the task of fluffing the other man’s long, thick cock for her.</p><p>“Is he a good cocksucker?” Mistress Isabella asked the man Mitchell was eagerly blowing.</p><p>“He’s not bad,” Derek replied. “He’s not as good as you, of course.”</p><p>They shared a soft kiss as Mitchell continued to bob up and down in Derek’s lap. He refused to slow his effort just because his jaw ached. He wasn’t going to do anything to disappoint Mistress Isabella.</p><p>“He needs more practice,” Mistress Isabella said, “and I’m going to make sure he gets it. There will be plenty of time for my cum slut to suck cock. He’s going to be a fixture in the porn world, after all, and he’ll be doing a great deal of cocksucking for the videos he’s going to star in. It’s nice to have a fluffer around, too. I like being able to assign him the task of sucking cock while I watch.”</p><p>“It is nice to have an eager cocksucker around when I’m not in the mood to exhaust my mouth with a massive cock,” Mistress Emily said as she stroked her man’s cock.</p><p>“That’s why I trained Mitchell,” Mistress Isabella replied. “Every domme needs a submissive cocksucker and cum slut. He makes life a little bit easier, and it’s such a thrill to witness his desire to be degraded and humiliated like the cum dumpster he is.”</p><p>As humiliating as it was, Mitchell relished the dialogue between the two dommes in the room. He enjoyed being talked about like he was an object for their use and pleasure, mostly because that’s exactly what he was in Mistress Isabella’s presence.</p><p>“That’s good, Mitchell,” his mistress said as she gently pulled his head from Derek’s dick. “Now use your talented mouth on Mark’s cock.”</p><p>Mitchell crawled towards the man sitting next to Mistress Emily and wrapped his lips around the equally-sizable cock. He moved up and down the long, thick shaft. He worked the underside of the cock head with his tongue. He relished making the other man moan.</p><p>“You like being a good cocksucker for your mistress, don’t you Mitchell?” Mistress Emily asked.</p><p>He looked up at her and nodded as best as he could with a thick cock in his mouth.</p><p>“Of course you do. It feels good to serve, doesn’t it? It feels good to have found your place as a cum slut and cocksucker for your mistress. It feels good to know that you have a purpose, that your life is about making her happy instead of making yourself happy,” she said.</p><p>Mitchell nodded once more as he took as much of Mark’s big cock into his mouth as possible.</p><p>“I envy you, Isabella,” she said. “A submissive like Mitchell is hard to find. Most aren’t nearly as pliable as he is, and I think we both know most are far more selfish.”</p><p>“Honestly, I think it helps that he gets to cum,” Mistress Isabella said. “Orgasm denial is not a significant part of his training. I put him in chastity when he’s here, but otherwise I let him masturbate as much as he wants. He just has to eat his cum every time he orgasms.”</p><p>“How much cum do you think your submissive slut has eaten since you began training him?” Mistress Emily asked.</p><p>A gleeful laugh rang out as Mistress Isabella expressed what seemed to be genuine joy as she considered how much cum she’d managed to make Mitchell consume in their time together.</p><p>“I’m quite certain he’s eaten hundreds of his own loads,” she said. “He can’t help but cum multiple times a day and he’s under strict orders to consume everything he produces, so I know he’s become quite the connoisseur of his own seed. He’s eaten several dozen loads of cum from other men, too.”</p><p>“He truly is a cum slut,” Mistress Emily replied.</p><p>“Oh, we’re just getting started,” Mistress Isabella said. “Mitchell is going to consume thousands of loads of cum before I’m done with him. He’s going to consume more cum than almost anyone would in their lifetime, and he’s going to do it in the span of just a few years.”</p><p>Mitchell knew it was a little strange to find that notion so arousing, and yet he couldn’t help it. His dick throbbed in the chastity cage as he thought of being made into such a wanton cum slut that he’d end up consuming more seed in a few years than most people do in a lifetime.</p><p>“I have to say, all this talk of turning your submissive into the ultimate cum slut has left me desperate to get fucked,” Mistress Emily said.</p><p>“That’s enough, Mitchell,” Mistress Isabella said. “You’ve served your purpose. Now you may watch as these men serve their purpose.”</p><p>Mitchell watched from his knees as the two beautiful women in the room lifted their skirts and pulled down their panties. They each straddled the naked, well-hung, freshly-fluffed man sitting next to them on the couch and took the big, beautiful cocks inside them.</p><p>Soon the sounds of sex filled Mistress Isabella’s lovely loft apartment as Mitchell soaked it all in. He looked from one beautiful woman to the next and admired how their pussies looked so tight as they stretched around the thick cocks filling them. He felt a sense of pride at having been responsible for fluffing the big dicks that were currently providing such pleasure.</p><p>“Why don’t you suck on his big balls, Mitchell?” Mistress Emily said.</p><p>Mitchell crawled into place, lowered his head, and took Mark’s large testicles into his mouth. He gently sucked and eagerly licked on the wrinkled, hairy flesh and his nose filled with the scent of manhood.</p><p>Again Mitchell felt a sense of pride, this time when Mark unleashed a deeply-satisfied groan. He seemed to enjoy the way Mitchell’s mouth felt on his balls.</p><p>“Is he sucking your nuts like a good cuckold?” Mistress Emily asked.</p><p>“He certainly is,” Mark replied.</p><p>Mitchell’s cock ached in its chastity cage as he played his part in the hardcore foursome happening around him. He heard the sounds of Mistress Emily’s pussy being penetrated just a few inches from his mouth. He felt her ass brush against his head as she rode the man whose cock rested so deep inside her. He even tasted a little bit of her wetness as it dripped down Mark’s shaft and onto his balls.</p><p>“He’s a cum hungry cuckold,” Mistress Isabella said. “That’s why he’s so eager to suck on a big pair of balls or give head. He wants his reward. He wants to feel a thick, creamy load of a superior man’s seed on his tongue. He wants to lick it out of your pussy like a good little cum slut. He wants to feel it in his mouth and sliding down his throat. He wants to know that he has another man’s cum in his stomach.”</p><p>All of it was true. Mitchell could hardly believe that he’d come so far and allowed himself to be turned into a wanton cum slut, but it had happened. There was no question about it. He was what Mistress Isabella described. He wanted his reward. He wanted to devour the loads of the two men having sex in the living room. He wanted to clean their cum from the perfect wet cunts of the women getting fucked. He wanted it desperately.</p><p>“Come over here, Mitchell,” Mistress Isabella said. “I want you to worship my ass.”</p><p>Mitchell crawled towards his mistress and pressed his face between her ass cheeks. Her skirt fell around his head while he worshiped her asshole just as she’d demanded.</p><p>Once again the sounds of beautiful sex filled his ears as his tongue ran back and forth over her asshole, providing the woman he worshiped with a burst of pleasure each time.</p><p>Mitchell stayed between the ass cheeks of his mistress until both women experienced loud, lusty orgasms. He licked asshole while he listened to them cum almost simultaneously.</p><p>He only stopped worshiping ass when Mistress Isabella reached back and gently pushed his head from between her ass cheeks with a delightful laugh.</p><p>She climbed off of Derek’s cock and Mitchell looked up at the long, slick shaft and licked his lips. He felt genuine desire for it. He wanted to taste the juices his mistress had left on the other man’s cock. Plus, he wanted to show that he was a good submissive for her by giving head. He wasn’t going to do so until he’d been ordered, though.</p><p>“Suck his cock, Mitchell,” Mistress Isabella ordered. “Clean my juices off of him. Show me what a good little submissive you are.”</p><p>Mitchell devoured the big cock in front of him. He sucked and slobbered and he cleaned the shaft like his mistress desired.</p><p>“Now suck on his balls,” she said.</p><p>Mitchell did as he was told once more. He sucked and licked Derek’s big balls, bathing them with his tongue and licking up the mixture of sweat and pussy juice that had collected there.</p><p>“Lick his taint,” she demanded.</p><p>Mitchell dropped lower and licked the small strip of flesh between Derek’s balls and asshole. He licked up the sweat and despite the poor taste he didn’t hesitate to do as his mistress demanded.</p><p>“Come over here, Mitchell,” Mistress Emily said.</p><p>Mitchell crawled between Mark’s legs and looked up at the beautiful blonde that had ordered him into place.</p><p>“Lick his cock clean,” she said. “No sucking. Just lick it like the most delicious lollipop you’ve ever had in your mouth.”</p><p>Mitchell used his eager tongue to lick up and down Mark’s shaft. The mixture of cock and pussy juices was delicious and he thoroughly enjoyed getting to look into Mistress Emily’s eyes and see her delightful smile as he acted like the submissive he’d been trained to be.</p><p>“Scoot to the edge of the couch, Mark,” Mistress Emily said.</p><p>Mark did as he was told and Mitchell looked up at the blonde as he waited for his next order.</p><p>“Eat his ass, Mitchell,” she demanded.</p><p>Mitchell dropped lower, spread Mark’s ass cheeks, and gave a rimjob. It wasn’t anywhere near as pleasurable as eating Mistress Isabella’s ass, but he knew that was the point. He was offering his submission via his tongue. He was eating ass precisely because it was humiliating and he found pleasure in that.</p><p>“It’s nice to see that he’s so eager to go the extra mile,” Mistress Isabella said. “Perhaps I’ve done an even better job of training him than I thought.”</p><p>“I think you have,” Mistress Emily replied. “I suspect you’ll discover that Mitchell doesn’t really have limits, that you could push him to depths you never imagined possible.”</p><p>Mitchell suspected it was true. He couldn’t know for sure, but he’d done everything that had been requested of him so far and he wasn’t sure there was a limit.</p><p>“Let’s take this to the bedroom,” Mistress Isabella said. “Mitchell deserves his reward, after all.”</p><p>Mitchell followed as the two beautiful women in the room took their men to the bedroom.</p><p>“Get on your back in the bed,” Mistress Isabella said to Mitchell.</p><p>He smiled and did as he was told and was delighted to see Mistress Emily get on top of him. Her pussy hovered over his face and looked slippery and stretched out from the hard fucking she’d enjoyed.</p><p>Mark moved behind her and slapped his dick against Mitchell’s lips. “Open up, slut,” Mistress Emily said.</p><p>Mitchell parted his lips and Mark’s cock slid into his mouth and to the back of his throat. A gentle face fucking soon began, with Mitchell taking most of the dick over and over. He felt used in the most pleasurable way imaginable.</p><p>When Mark pulled out and slid into Mistress Emily’s pussy the beautiful women moaned. She grabbed Mitchell’s locked up cock and tugged on it before spitting on his balls and rubbing them aggressively. She filled him with pure delight as he witnessed her getting fucked in close up.</p><p>“Cum when you’re ready,” Mistress Emily said. “Cum in my pussy and I’ll feed the cuckold.”</p><p>Mark grabbed her hips and pounded harder into the slick cunt that surrounded his cock. Little droplets of pussy juice dripped onto Mitchell’s face as he watched with a lusty smile on his face.</p><p>Soon enough Mark groaned and held his cock inside the pussy he’d been pounding with such vigor. He unleashed his load, spilling his seed deep in the perfect cunt and groaning with such delight that Mistress Emily couldn’t help but laugh.</p><p>The moment Mark pulled out she sat on Mitchell’s face. He opened his mouth and pushed his tongue inside her, feasting on the flood of cum that followed.</p><p>“That’s a week’s worth of cum, Mitchell,” Mistress Emily said. “He saved up just for you. He built up a nice big nut so you could swallow it.”</p><p>Mitchell swallowed everything that entered his mouth. He swallowed the hot cum eagerly. He savored the salty aftertaste before more flowed into his oral cavity. He felt like the cum slut Mistress Isabella had turned him into.</p><p>When Mistress Emily climbed off his face Mitchell smiled gleefully. He had a bellyful of cum and it provided him with a deep sense of pleasure.</p><p>“Look at the happy little cum slut,” Mistress Emily said. “He truly loves being a cum slurping whore for you, doesn’t he?”</p><p>Mistress Isabella smiled, got in the bed, and sat on Mitchell’s chest. Her pussy was inches from his face as she said, “He certainly does, and he’s about to eat another load.”</p><p>Derek moved into position at the edge of the bed and slid into her pussy. His balls rested on Mitchell’s face as he held his cock deep inside Mistress Isabella’s perfect cunt.</p><p>“You’re going to use your tongue to pleasure him, Mitchell,” she said. “And he’s going to use his cock to pleasure me before he pumps a thick load in my pussy. Do you understand?”</p><p>“Yes, mistress,” Mitchell answered.</p><p>Derek began to fuck her and Mitchell did as he was told. He used his tongue to lick the cock and the balls that passed over his mouth. He spread his saliva and enjoyed the humiliation of being used as little more than furniture by the woman he’d come to worship.</p><p>“Is he using his tongue?” Mistress Isabella asked. “Is he being a good submissive and working hard for his reward of a thick, creamy load of cum?”</p><p>“He is,” Derek said.</p><p>He fucked the beautiful woman harder and faster as Mitchell made sure to keep his tongue extended.</p><p>When Derek buried his cock inside Mistress Isabella’s perfect pussy and began to cum, Mitchell licked and sucked on his big balls to make the orgasm more pleasurable.</p><p>Derek pulled out and Mitchell looked at the pussy that rested just a few inches from his mouth. He saw a stream of thick, delicious-looking cum start to slowly seep from her.</p><p>“Are you hungry, cuckold?” she asked.</p><p>“Yes, mistress,” he replied.</p><p>Mistress Isabella smiled and sat on Mitchell’s face. He devoured his second load in just a handful of minutes. It took was thick and rather massive.</p><p>“This is your place, Mitchell,” she said while looking down at him. “You are a cuckold. You are a cum slut. You are meant to serve superior women like me and Mistress Emily. You are meant to accept your place as an inferior man. You are meant to devour cum like a good slut. You are meant to offer yourself for the pleasure of your superiors. Do you understand that?”</p><p>Mitchell nodded as he pushed his tongue deep inside the woman feeding him a thick load.</p><p>“That’s good, Mitchell, because I intend on keeping you around for a long, long time, but that can only happen if you accept your place. You can only be my submissive if you understand that you exist to serve my needs. You exist to make me happy. You exist to be a cuckold cum slut for me.”</p><p>Mistress Isabella lifted her pussy off his face and Mitchell said, “I understand, mistress. I’ll be a good cuckold cum slut for you, I promise. I know my place. I’ll do as I’m gold. I’ll serve your needs. I will, I promise.”</p><p>Mistress Isabella smiled, sat on his face, and fed Mitchell more of the cum that had been injected deep inside her.</p><p>“You’re mine now, Mitchell. You’re mine for as long as I want you. You’re my good little cuckold cum slut,” she said.</p><p>Every word of it was true. Mitchell could be hers for as long as she wanted him. He needed her. He needed to submit to her. He needed to be her cuckold cum slut.</p><p>The End</p>
