Her hair was pulling into a ponytail that proved quite alluring.</p><p>Mitchell was naked and on his knees in her loft as Mistress Isabella walked around him in slow circles.</p><p>“Fifteen,” Mitchell answered.</p><p>Mistress Isabella stopped in front of Mitchell and lifted his chin. She smiled down at him and said, “You’ve become quite the semen connoisseur, haven’t you?”</p><p>“Yes, mistress,” Mitchell replied.</p><p>As she’d done before, Mistress Isabella had instructed Mitchell to consume every bit of cum he expelled from his body while they were apart. His recent adventure as a cum eating cuckold in a porn video had taken Mitchell to a place of deeply kinky arousal and he’d been masturbating furiously in the week since he acted as a cuckold and cum slut in a foursome.</p><p>“You don’t even hesitate anymore, do you?” she asked.</p><p>“No, mistress. I don’t. I look forward to it now. Even though climaxing depletes my desire, I thoroughly enjoy eating my cum. It makes me feel good, like I’m making you happy and serving my purpose as you’ve taught me.”</p><p>“That’s because you’re a well-trained cum slut,” Mistress Isabella said as she ran her finger over Mitchell’s lips. “You’ve come to crave the taste of semen. You’ve begun to associate it with satisfaction, even after you’ve had your orgasm.”</p><p>“Yes, mistress,” Mitchell replied. She was absolutely correct. He’d begun to fantasize about eating cum. He’d started seeing it in his dreams, which had grown more lurid after his performance in the porn video. His journey into bisexual territory had opened up something in his head and unearthed a surprising kind of lust for that sort of play.</p><p>“Open up,” Mistress Isabella said.</p><p>Mitchell parted his lips and she gently placed two fingers on his tongue before saying, “Suck.”</p><p>He looked up at his mistress and sucked on her fingers like he was sucking a cock. He offered her whatever oral pleasure she allowed and when she smiled Mitchell felt a genuine sense of joy.</p><p>“Stay,” Mistress Isabella said as she pulled her fingers from his mouth and spun around.</p><p>She disappeared into her bedroom and returned a few moments later holding a dildo with two leather straps attached to it.</p><p>“Open up,” Mistress Isabella said once more.</p><p>Mitchell opened his mouth as he studied the dildo, but it wasn’t until she placed it into his mouth and attached the straps behind his head that he realized that Mistress Isabella was silencing him with a dildo gag.</p><p>“It seems fitting for a cocksucker like you, doesn’t it?” she asked.</p><p>Mitchell’s cock throbbed between his legs at the use of the word cocksucker. It was humiliating in the most arousing way possible, and even if his mouth hadn’t been gagged it would have been hard to argue with. He’d given a blowjob and he’d done so willingly.</p><p>“I have a guest coming over. You’re going to watch us fuck and then I’m going to give you the privilege of eating a creampie. Does that make you happy, cum slut?” Mistress Isabella said.</p><p>Mitchell nodded as the dildo gag made it impossible to speak. He would have thanked his mistress if it had been possible to utter even a single word.</p><p>“Follow me,” Mistress Isabella said. “Crawl.”</p><p>Mitchell crawled behind the beauty as she walked into her bedroom once more. Mistress Isabella pointed to the floor and Mitchell crawled into place and watched her sit on the edge of the bed.</p><p>“Remove my boots,” she said.</p><p>Mitchell reached up and slowly unzipped each boot before pulling it off and exposing her long, smooth, toned legs. He let his fingers move delicately over her soft skin, a gesture that brought a smile to Mistress Isabella’s face.</p><p>“Good boy,” Mistress Isabella said as she stood up and turned around. “Remove my shorts.”</p><p>Mitchell pulled the tight-fitting shorts off his mistress and watched her perfect ass appear in front of him. Mistress Isabella bent over and her ass cheeks opened, offering him a view of her asshole.</p><p>“I’ll bet you wish you weren’t wearing that dildo gag, don’t you? Then you’d be able to kiss my pretty little asshole. A cuckold cum slut doesn’t always get what he wants, does he?” Mistress Isabella asked.</p><p>She was right. He wanted to kiss her asshole. He wanted to worship it. He wanted to make her moan as he tongued her tight hole, but it wasn’t to be.</p><p>“Stand up,” she said. “Loosen the corset.”</p><p>Mitchell stood and did as he was told by carefully loosening the strings that held her tight corset in place. Mistress Isabella then reached back and freed herself from it before turning around. She was naked and she looked glorious as Mitchell’s eyes wandered over her body. </p><p>“You like what you see, don’t you cuckold?” Mistress Isabella asked as she grasped his balls and gently pulled on them.</p><p>He nodded as she released his testicles and ran her index finger along the base of his erect cock. She played with the tip and rubbed the precum around, making Mitchell moan around the dildo gag in his mouth.</p><p>“Would you like to dress me, cuckold? Would you like to put me in lingerie so I can look good for the real man that’s coming to fuck me?” Mistress Isabella asked.</p><p>Mitchell nodded as she stepped back and moved towards her walk-in closet. “Come,” she said.</p><p>He followed Mistress Isabella into her spacious closet and admired the selection of elegant outfits, casual clothes, and beautiful lingerie that lined the shelves and hung from hangers.</p><p>“He prefers something a little more feminine,” she said while gently looking through her selection of babydolls. “How about this one?”</p><p>Mistress Isabella held up a sheer blue babydoll with delicate lace trim as she smiled at Mitchell. He nodded in vigorous agreement, knowing full well it would look amazing on her.</p><p>She picked up matching blue panties and stockings and they moved back into the bedroom. Mistress Isabella sat on the edge of her bed and handed Mitchell one of the nylons as she presented her foot.</p><p>He bunched up the stocking and then gently slipped it over her foot and pulled it up her legs, making sure to avoid creating a run and ruining the look. He repeated the process with her other leg, making sure to caress her nylon-clad skin in the process.</p><p>“Isn’t it nice to dress your mistress for another man to fuck? Doesn’t it thrill you to know that you’re making me beautiful so someone else’s cock will get hard for me?” Mistress Isabella asked as she handed Mitchell the blue panties.</p><p>He nodded as he helped her into them and looked up as his mistress stood so he could pull the panties up her long, lovely legs.</p><p>“Stand for me, Mitchell. Put the last piece on. Finish making me look beautiful for him,” Mistress Isabella said.</p><p>Mitchell stood and picked up the delicate babydoll. He gently helped his mistress into it and watched as it fell into place. The material seemed to float just above her skin and it made her perky breasts look particularly good.</p><p>“Do you think he’ll want to fuck me, cuckold?” she asked.</p><p>Mitchell nodded.</p><p>“He’ll be here soon. Please let him in when he rings the bell,” she said.</p><p>Mistress Isabella disappeared into her bathroom as Mitchell stood at the foot of her bed and waited. When the bell rang a few minutes later he opened the door and welcomed a tall, handsome, well-built man into her apartment. Mistress Isabella clearly had a type.</p><p>The man smiled at Mitchell before walking past him and into Mistress Isabella’s bedroom. He was clearly there with a singular purpose in mind.</p><p>“Welcome, David,” Mistress Isabella said before the tall man took her into his arms.</p><p>Mitchell entered the bedroom and watched his mistress give herself over to the man she was kissing. Her hands moved over his body and then pulled off his coat and unbuttoned his shirt. She moaned as he squeezed her ass and gently played with her breasts through the thin, delicate material of her absurdly sexy lingerie.</p><p>“I’ve missed you,” she said as her hand moved between his legs and unzipped his pants. “And of course I’ve missed your cock.”</p><p>David groaned as Mistress Isabella pulled out his big cock and gently stroked it.</p><p>“Come over here, cuckold,” Mistress Isabella said as she removed David’s pants and tossed them aside.</p><p>Mitchell approached as his mistress looked up at her lover. They kissed again, their bodies pressed together as she played with his big cock.</p><p>“I’d like my cuckold to suck your cock,” she said.</p><p>David glanced at Mitchell and smiled. “You know I’m up for anything,” he said.</p><p>Mistress Isabella turned to Mitchell and freed him from the dildo gag before saying, “Get on your knees, cocksucker.”</p><p>Mitchell’s dick throbbed as he fell to his knees in front of his mistress and her lover. Mistress Isabella grabbed David’s cock and directed it towards Mitchell’s mouth.</p><p>“Show me what a good cuckold you are,” she said.</p><p>Mitchell admired the bulbous, throbbing head of David’s cock for a moment before wrapping his lips around it and giving a blowjob. He spread his saliva over the taut skin of the big dick and moved as deep down on it as he could, repeating the process over and over to give pleasure to the man that would be fucking his mistress.</p><p>“He’s not bad,” David said.</p><p>Mistress Isabella smiled as she ran her hands through Mitchell’s hair and said, “Do you hear that, cuckold? You should enjoy that praise, especially for a new cocksucker. Just think of how good you’ll be before long. I’ll train you to be an expert at pleasing men, especially since your only hope for a satisfying long term relationship is to be a loving woman’s cuckold husband that gladly sucks cock and eats pussy when called upon to do so.”</p><p>Mitchell sucked harder and faster on the big cock in his mouth. He offered David the pleasure any man would have enjoyed and he moaned. He couldn’t help it. Mistress Isabella’s humiliating words wormed their way into his arousal center and left his body buzzing with the kind of desire he’d become familiar with as her cuckold.</p><p>“That’s enough, cocksucker,” she said. “It’s time for me to get fucked.”</p><p>Mitchell pulled back and the big cock slipped from his mouth. His saliva coated the head and left it looking shiny and ready to fill Mistress Isabella, just as she desired.</p><p>“Do you want to watch him fuck me?” Mistress Isabella asked.</p><p>“Yes, mistress,” Mitchell answered.</p><p>Mistress Isabella reached under her babydoll and pulled down her panties, revealing her wet pussy.</p><p>She wrapped her fingers around David’s cock and walked to the side of her bed before releasing him and moving onto her back. David smiled, crawled on top of her, and they shared a passionate kiss as Mistress Isabella reached between her legs and guided the other man’s cock inside her.</p><p>Mitchell moved to the side of the bed and watched from his knees as Mistress Isabella’s pussy opened to accommodate the cock seeking to fill her. A low, beautiful moan of pleasure escaped her lips as David bottomed out inside her and Mitchell felt his cock swell as his pelvis tingled with a kind of arousal he’d rarely experienced in his life.</p><p>It wasn’t just that he was watching a beautiful woman open for a big cock. It wasn’t just that he was playing the part of her submissive cuckold. It was that Mitchell knew what was coming. The point of the sex unfolding in front of him was for David to cum inside her. It was to prepare a creampie for Mitchell to consume. For the first time he was going to lick a load of another man’s cum out of the perfect pussy of the woman he’d become utterly obsessed with.</p><p>They fucked in missionary until Mistress Isabella achieved an orgasm. Afterwards, she and David kissed and caressed each other for a few minutes while his cock stayed buried deep inside her.</p><p>“Take me from behind,” she said.</p><p>David pulled out and Mistress Isabella got on her hands and knees facing Mitchell.</p><p>“I’d never let a cuckold like you fuck me from behind,” she said as David slid into her pussy. “A man like David, though, can take me from behind when he desires it. It feels good to get fucked by a man. It doesn’t really feel like anything to get fucked by a cuckold like you, Mitchell.”</p><p>Mitchell watched her beautiful breasts bounce with every thrust into her pussy as she offered sensual humiliation that made his dick throb.</p><p>“You understand that now, don’t you?” she asked. “You understand that you’re a cuckold, that you can’t possibly please a woman like she needs to be pleased, that you don’t ever deserve to fuck a woman, right?”</p><p>“I do,” Mitchell said.</p><p>Mistress Isabella smiled and closed her eyes as David fucked her harder.</p><p>“You understand that it’s your place to eat the cum of superior men, don’t you?” she asked.</p><p>“I do,” Mitchell said.</p><p>The sounds of hard sex filled the bedroom. Every thrust created beautiful slapping noises as the bodies of two beautiful people met over and over. David’s moans were low and animalistic and Mistress Isabella’s were high and lusty and it seemed as though she was going to cum again.</p><p>“You like it, don’t you?” she asked. “You like eating other men’s cum. You like eating your cum. You’re a fucking cum slut, aren’t you?”</p><p>“Yes, mistress,” Mitchell said. “I’m a cum slut. I’m your cum slut.”</p><p>She smiled and reached out to beckon Mitchell closer. He crawled towards her and Mistress Isabella grabbed a handful of his hair and pulled it tight.</p><p>“Yes you are,” she said. “You’re my cuckold cum slut and you’re going to be my cuckold cum slut until I say otherwise, aren’t you?”</p><p>“Yes, mistress,” Mitchell answered.</p><p>Mistress Isabella pulled him closer and surprised Mitchell by pressing her lips against his for a long, deep kiss with a surprisingly active tongue.</p><p>She held Mitchell close after the kiss with her eyes locked on his. David fucked her harder and faster and his moans grew louder.</p><p>“I hope you’re hungry, cuckold, because he’s going to cum inside me,” she said.</p><p>A few moments later David plunged his cock inside Mistress Isabella and unleashed his seed. A sensual smile broke across her face as the other man pumped his seed inside her.</p><p>“How many days since you last came?” she asked.</p><p>“Six,” David said.</p><p>She smiled and looked at Mitchell. “I asked him to save up a little for you, cuckold. I wanted you to have a nice big load to clean out of my pussy. Now, are you ready?”</p><p>“Yes, mistress,” Mitchell replied.</p><p>David pulled out and Mistress Isabella flipped onto her back and spun around. She spread her legs and Mitchell stared between them. She reached down, spread her pussy lips, and revealed that a little of David’s cum was ready to be consumed.</p><p>“Come closer, cum slut,” she said.</p><p>Mitchell crawled into the bed and took his place between her legs.</p><p>“You look so happy,” Mistress Isabella said.</p><p>“I feel happy,” he replied. “Being between your legs brings me joy, especially considering what I’m about to do.”</p><p>“And what’s that, cum slut? What are you going to do?” she asked.</p><p>“I’m going to clean your pussy. I’m going to lick David’s thick cum out of you and swallow every drop of it. I’m going to be the cuckold cum slut you’ve trained me to be,” Mitchell answered.</p><p>Mistress Isabella smiled and caressed the side of his face as she said, “Yes you are. You may clean me.”</p><p>Mitchell let his head fall between her legs and gently kissed her labia before inserting his tongue into Mistress Isabella’s pussy and scooping out some of David’s cum. He savored the salty taste for a moment before swallowing the thick fluid.</p><p>“How does he taste?” she asked.</p><p>“It’s delicious, mistress. Thank you for letting me clean your messy pussy,” Mitchell said before returning to his task.</p><p>He pushed his tongue deeper inside her and found a reservoir of semen. Mitchell scooped out as much as he could and swallowed it all. The fluid coated his tongue and throat, leaving him with a delicious aftertaste that he savored for a few moments before returning to her pussy.</p><p>“He likes your cum, David,” Mistress Isabella said to her lover.</p><p>“Good,” David replied. “Because I’d love to put another load in you before we’re done here.”</p><p>“I’m counting on it,” she said. “It’s been far too long since I had a cock like yours inside me and I’m keeping you here as long as I can.”</p><p>David joined Mistress Isabella in the bed and they kissed as Mitchell continued his work. He felt an extra sense of giddiness at the notion that he’d get to clean more than one creampie from her pussy.</p><p>“You’ve trained him well,” David said as he played with Mistress Isabella’s breasts.</p><p>“I know,” she said. “It took a little time, but he’s become a full-fledged cuckold cum slut, with a dash of cocksucking on the side just to make things a little more exciting.”</p><p>“Maybe he should suck my dick after he’s done cleaning you. He could get me nice and hard for another round of pounding that perfect pussy of yours,” David suggested.</p><p>“Would you like that, Mitchell? Would you like to fluff David’s cock until he’s hard for me? It might take a little longer this time,” Mistress Isabella asked.</p><p>Mitchell looked up from the pussy he was diligently cleaning and said, “I’d love the chance to fluff him, mistress. Thank you.”</p><p>“You’re such a good little slut for me,” she said.</p><p>Mitchell pushed his tongue back inside her to clean whatever was left of David’s load. She tasted splendidly sexy and he could have stayed between her legs all day. There was another task, though, and Mitchell was going to deliver as he’d promised. He was going to be a good cuckold and suck cock for his mistress.</p><p>“I want you to cum, Mitchell,” Mistress Isabella said. “I want you to jerk off into your hand and eat it right now.”</p><p>Mitchell looked up at her. He didn’t want to cum. He knew it would sap his desire. He knew it would make fluffing David harder.</p><p>“Do it, Mitchell. Prove to me that you’re a good cuckold. Drain your desire by jerking off, then eat your cum and get to work sucking David’s cock. Show me that you don’t need to be turned on to be a good cuckold slut for your mistress,” she said.</p><p>Mitchell moved to his knees and jerked off as he watched Mistress Isabella and her lover kiss. He listened to her moan and he felt a mixture of intense arousal and mild jealousy. There was a sense of dread, too, as he knew he wasn’t going to want to suck cock after he climaxed. It didn’t matter, though. Making Mistress Isabella happy was too important. He had to do as he was told. He had to prove that he was a good submissive for her.</p><p>Mitchell climaxed in his hand and the moment he was finished he lifted it to his mouth and swallowed every drop. He wiped his hand clean and then crawled between David’s legs. He knew his task. He was to be a fluffer. He was to get the other man hard for his mistress.</p><p>The act of sucking cock felt mildly repulsive in the aftermath of his orgasm, but it didn’t matter. He did it anyway. He wrapped his lips around the semi-erect dick and he gave a blowjob. He sucked cock because it’s what his mistress wanted, not because it turned him on. He sucked cock because that’s what he was.</p><p>“That’s two loads so far,” Mistress Isabella said as she pushed Mitchell’s mouth deeper onto David’s cock. “I wonder how many we can feed him before the evening is over.”</p><p>“I think we can get to half a dozen, at least,” David said.</p><p>Mistress Isabella laughed and kissed her lover as she made Mitchell gag on the cock in his mouth.</p><p>“I hope you’re hungry, cum slut,” Mistress Isabella said.</p><p>Mitchell was always hungry for more cum.</p>
