Go. Have fun. There are some things I want to take care of around here before we move out and this will be a perfect day to do them.”</p><p>Bella stepped closer and put her arms around him. Zack pulled her into a tight hug and kissed the top of her head before Bella looked up, smiled, and said, “Would you like it if I brought home a treat for you?”</p><p>“Yes,” Zack admitted. It felt a little odd to openly admit that he wanted his girlfriend to bring home a load of Luke’s cum for him to clean out of her, but they both knew it was true so there was no sense in lying about it.</p><p>“You’ll clean me?” Bella asked.</p><p>Zack’s cock stirred in his pants and when Bella kissed his neck and moaned he reached an erect state in almost no time. “Yes, I’ll clean you,” Zack replied. “You know I love to clean you, Bella. You know I love to make you happy.”</p><p>Bella kissed him with a level of passion that caught Zack off guard. It was the sort of kiss that was offered as a form of foreplay, though Zack had been on the receiving end of quite a few kisses like that in the month since it had been revealed that Bella knew all about her mother’s quest to train Zack to be a good cuckold. Bella seemed to be in a perpetual state of arousal and she found quite a bit of pleasure in teasing Zack in all manner of ways.</p><p>“I love that you’re so eager to make me happy, Zack,” Bella whispered. “It makes me so happy to know that my future husband is already well on his way to being a good cuckold.”</p><p>Before he could say anything in response, Bella gave Zack a kiss on the cheek, turned, and headed out the front door to spend her day with Luke. Zack watched her go and then headed for the kitchen to put together a quick lunch before tending to the list of tasks he wanted to accomplish before he and Bella moved out.</p><p>“Good afternoon, Zachary,” Camilla said as he stepped into the kitchen to find her sitting at the table with a cup of tea steeping in a mug.</p><p>“It is a good afternoon,” he replied with a smile as he glanced at Camilla’s cleavage, which was on full display in a tight, v-neck sweater.</p><p>“Tell me, Zachary, how are you doing?” Camilla asked.</p><p>“In what way?” Zack asked.</p><p>“You’re about to take the next step on your path to being my daughter’s cuckold husband,” Camilla said. “You’re going to move in together and she’s going to take over the bulk of your training. Whether you know it or not, it’s going to mean a shift in your relationship, though with any luck it will be gradual.”</p><p>Zack hadn’t considered that his life would be changing in any tangible way outside of having more space and not having his future mother-in-law in the house each and every day. “What sort of shift?” he asked.</p><p>Camilla gently dunked the tea bag in the water and smiled. “So far, I’ve been the one shaping your evolution as a cuckold. At times, I’ve had to use a firm hand to make sure that you do as you’re told. I’ve done it all in service to my daughter’s happiness, as I understand her better than almost anyone. Now, though, Bella is going to take over. She’s going to be the one shaping your evolution. She’s going to make you exactly as she wants you to be, Zachary, and you may find that she’s a different woman than the one you’ve come to know once she’s in charge.”</p><p>“What do you think she’ll do differently?” he asked.</p><p>Camilla wrapped two hands around her mug, smiled, and said, “I think you might be underestimating my daughter’s desire to have life exactly as she wants it, Zachary. I think I helped open her eyes to just how good a woman can have it when she’s willing to take control of the man in her life and I suspect Bella will demand quite a lot of you once you’re living alone under the same roof. I’ve cautioned her to take her time, but young people can be so impatient.”</p><p>Zack didn’t feel even a hint of anxiety at the idea of Bella taking charge in a way that surprised him. If anything, he was eager to do whatever his girlfriend wanted. He’d already come so far and done so many things he never expected, so he wasn’t sure what Bella could ask of him that he wouldn’t be willing to do.</p><p>“Do you know why Bella insisted on you renting a place with three bedrooms?” Camilla asked.</p><p>Zack took a moment to consider the question and was surprised to find that he didn’t know why. He hadn’t bothered asking, largely because he just wanted Bella to be happy. “Do you know why?” he replied.</p><p>Camilla sipped her tea, savored the taste for a second, and swallowed as she nodded. “I do, Zachary. She wanted a master bedroom, a second bedroom to turn into an office, and a guest bedroom for you to sleep in when she invites Luke – or another lover – to spend the night in the master bedroom.”</p><p>Zack felt his heart rate jump as he considered the notion of Bella kicking him out of the bedroom in favor of another man. At first he told himself that it was insane, that Camilla was just guessing at what her daughter wanted, but Bella had already spent the night at Luke’s place a few times and it didn’t actually seem out of the realm of possibility that she would invite him to sleep in their bed as well.</p><p>“I don’t know when she’s going to invite him to spend the night, but it will happen, Zachary,” Camilla said. “You’ll spend the night in the guest room while Bella falls asleep in Luke’s arms. You’ll likely have to listen to them having sex, too, as there’s very little reason to invite a man to spend the night if you’re not going to indulge in your desire for him the next morning. Will you be able to handle that, Zachary?”</p><p>Zack pulled out a chair at the kitchen table and sat down. His heart was pumping even harder now, though it wasn’t entirely from a sense of anxiety. There was arousal mixed in too, at least based on the rather pleasant feeling emanating from between his legs.</p><p>“I think I will,” he answered. “Be able to handle that, I mean. Though I guess I don’t know. Maybe it would be really painful.”</p><p>Camilla reached out and took his hand in hers. He closed his eyes and smiled at how warm and soft her skin felt against his. “It will be painful,” she said. “At first, at least. That’s a part of your training that I simply can’t tend to, for it’s something you must experience firsthand. You’ll feel pain as you first try to come to terms with the idea that Bella has chosen another man to spend the night in your bed. Knowing that she’s somewhere else fucking Luke is one thing. Knowing that she’s in your bed fucking him – and being able to hear it – makes it impossible to avoid grappling with the idea that he’s sexually superior to you. That’s where the pain will come from, at first at least.”</p><p>Zack felt a little of that pain as he sat at the kitchen table, so he suspected Camilla was right.</p><p>“Here’s the beautiful thing though, Zachary,” she said. “Because you’re a cuckold – because you were born to be a cuckold – that pain will eventually transform into pleasure. It won’t happen the first night – it might take several nights – but it will happen. First you’ll find pleasure in knowing that Bella is having the sex she both craves and deserves. Then you’ll find pleasure in the knowledge that Luke – or any other man Bella chooses to bring home – is sexually superior to you. It’s one of the blessings of being a cuckold. Eventually, when you quiet the noise your pesky male ego makes, you come to embrace that experiencing that particular kind of humiliation is actually quite thrilling for you.”</p><p>Zack couldn’t wrap his mind around the idea that humiliation turned him on. He just didn’t want to believe it. What turned him on was making Bella feel good, not experiencing humiliation.</p><p>“I can see the resistance,” Camilla said. “I can see it in your eyes and your jaw and even your posture, Zachary.”</p><p>“I just…I don’t like humiliation,” Zack replied.</p><p>“You do, Zachary,” Camilla said. “It’s part of your DNA. It’s why you’re an ideal cuckold. Men like you often want to argue this point – some go their whole lives without admitting it – but the key to your long term happiness is embracing your reality, Zachary.”</p><p>Zack knew Camilla had been right about so many things, but he couldn’t accept that she was right about this. It just didn’t seem possible that he could truly be aroused by humiliation. What kind of man was aroused by humiliation?</p><p>“Zachary, would you say it’s humiliating to lick another man’s cum from your girlfriend’s pussy?” Camilla asked.</p><p>Zack felt the urge to say no, but he knew it would be foolish to do so. “Yes,” he said.</p><p>“Would you say you find it arousing to lick another man’s cum from your girlfriend’s pussy?” she asked. “Or from mine, for that matter? Were you not turned on when I fed you Alex’s cum? Have you not been turned on the many times Bella has now fed you Luke’s cum?”</p><p>Zack closed his eyes for a moment and felt himself on his back in Camilla’s bed. He saw her pussy hovering over his face. He felt her lower it. He felt Alex’s cum pour into his mouth. He tasted the salty flavor once more. He felt a touch of the arousal he’d experienced that night.</p><p>“Yes, I was turned on,” Zack said as he looked away.</p><p>Camilla stood and moved her chair so she was sitting right next to Zack. She reached out and put a hand on his knee. Her fingers slowly moved up his thigh as he turned to see a smile on Camilla’s face. She leaned a little closer and he couldn’t help but glance at her cleavage, which looked utterly spectacular.</p><p>“I humiliated you by feeding you Alex’s cum,” Camilla said. “I chose him to fuck me – I could have chosen you, believe it or not, as Bella told me it would be okay if I deemed it necessary for your training – but I didn’t choose you, Zachary. I chose a man that could actually satisfy me, not one that would disappoint me. I chose you to clean Alex’s cum out of me. I chose you for the humiliating task that is worthy of a cuckold. I chose you for that and it turned you on. The humiliation turned you on, Zachary, just like it turned you on when Bella came home and fed you Luke’s cum. She could have invited half a dozen of her friends home to feed you their boyfriend’s loads and you would have found that thrilling too.”</p><p>Camilla moaned as her fingers reached Zack’s stiff cock. She hadn’t even touched him and he’d gotten hard, offering proof of her assertion that he found humiliation arousing.</p><p>“Why would Bella want me?” Zack asked. “If humiliation turns me on, why would she want me? Why would any woman want to marry a man that gets turned on by eating someone else’s cum out of his girlfriend’s pussy?”</p><p>Camilla slowly unzipped Zack’s jeans and freed his cock. She leaned closer and kissed his neck softly as she took him in her fingers and stroked him slowly. “That’s precisely why she wants you, Zachary. A good cuckold finds humiliation exceptionally arousing. He finds great pleasure in it, which makes him willing to embrace all manner of humiliating tasks, tasks that will no doubt make Bella’s life far more fulfilling.”</p><p>Camilla turned Zack’s head until her lips hovered achingly close to his. He stared into her eyes and they seemed to sparkle with delight. She leaned forward and their lips met. Camilla tilted her head and her tongue gently danced into Zack’s mouth before departing. She moaned and he couldn’t help but express his lust with a moan of his own.</p><p>“When Bella demands that you vacate the marital bed so she can welcome a superior man into your home, you’ll do so without hesitation because you’ll find it arousing, Zachary,” Camilla said. “When that man fucks her and she fills your home with her moans, your cock will stiffen as you listen from the guest bedroom, or perhaps from your knees on floor of the master bedroom as you watch him fuck your wife. When she demands that you clean his cum from her pussy to show her that you understand your place as her cuckold, you’ll do it joyfully, Zachary. Your cock will be stiff as you do it, too.”</p><p>Camilla kissed him again, though this time it was exceedingly passionate. Zack’s cock surged in her hand and he wondered if this was the day his future mother-in-law welcomed him into her pussy. She seemed so aroused and so intent on giving him pleasure that he couldn’t help but fantasize about experiencing the ultimate bliss with her.</p><p>“When Bella meets a man that finds it pleasurable to humiliate her husband, she’ll demand that you surrender to his desires,” Camilla said. “If he wants you to lick her clit while he fucks her, you’ll do it because humiliation turns you on, Zachary. If he wants you to place his cock inside her, you’ll do it.”</p><p>Zack couldn’t imagine touching another man’s cock, even for Bella’s pleasure. The idea seemed utterly horrifying to him, though his own cock remained quite stiff due to his overwhelming arousal as Camilla continued to stroke him and offer occasional kisses.</p><p>“If he wants you to suck his cock before he fucks your wife, you’ll do it,” Camilla said.</p><p>“No,” Zack replied. “I won’t.”</p><p>Camilla backed away a little and smiled. Her fingers remained wrapped around his cock but she ceased stroking him. “You will, Zachary. When your training is advanced enough, you’ll do anything you’re told. You’ll do it because you’ll understand it’s essential to Bella’s happiness and because you’ll crave the humiliation. You’ll crave the thrill that comes along with that humiliation.”</p><p>“I won’t give a blowjob,” Zack said. “I just won’t.”</p><p>Camilla leaned in closer once more. She kissed Zack’s neck and he groaned as her tongue worked its wondrous magic on his skin. “I’m certain there was a time when you would have said you’d never eat another man’s cum. In fact, I’m fairly certain you said something very similar to me, Zachary. And yet, now you’re an eager cum slut, aren’t you?”</p><p>Zack’s cock twitched in her hand as she offered up that humiliating term. His lust brought with it a touch of pain that quickly receded under the tidal wave of pleasure washing over him.</p><p>“Say it, Zachary,” Camilla demanded in a soft, seductive tone. “Say that you’re an eager cum slut for my daughter.”</p><p>“I’m…I’m an eager cum slut for your daughter,” Zack said.</p><p>“And for me too if that’s what I want,” Camilla whispered. “Isn’t that right, Zachary?”</p><p>“Yes,” he admitted.</p><p>Camilla released his cock, stood, and unzipped her jeans. She pushed them down and Zack stared between her legs as Camilla lowered her panties and revealed her pussy. His heart pounded. He was certain it was finally happening. He was going to fuck her.</p><p>“Some dreams never die, do they, Zachary?” Camilla asked.</p><p>He looked up at her and asked, “What?”</p><p>“I will never let you fuck me,” she said. “You’re not my cuckold, after all. I’m simply training you so my daughter can have the happy marriage that I missed out on. I understand if she lets you fuck her, but I never will. You couldn’t come close to satisfying me, and to allow you inside me would be degrading for me, Zachary.”</p><p>Camilla slipped two fingers into her pussy and Zack couldn’t help but note how wet she was. She was clearly turned on, though it seemed equally clear that she had no interest in fucking him.</p><p>Camilla sat, pulled her fingers from her pussy, and placed them against Zack’s lips. “Open up,” she said. Zack opened his mouth and Camilla slowly pushed her fingers inside. “Now suck.”</p><p>Zack thought of her assertion that he’d give a blowjob for Bella if it’s what she wanted. He knew what Camilla was doing. He knew she was training him for that moment that she seemed so certain would arrive at some point in his life. He knew it, and he wanted to resist, but the moment Camilla took his cock in her other hand Zack began to suck just like she wanted.</p><p>“That’s good, Zachary,” she whispered. “Now close your eyes for me.”</p><p>Zack closed his eyes and Camilla began to move her fingers in and out of his mouth. The taste of her pussy had subsided, but he suspected he’d be sucking for as long as she desired.</p><p>“It doesn’t feel bad to have my fingers in your mouth, does it, Zachary?” she asked.</p><p>He shook his head and she stroked his cock a little faster.</p><p>“Open up for one more,” she said. “Stretch those pretty lips of yours a little wider for me.”</p><p>Zack opened up and Camilla added a third finger to his mouth.</p><p>“Keep sucking while I move them in and out of your mouth, Zachary,” she instructed. “It feels good. Move your tongue over them, too. Show me that you want to make me feel good.”</p><p>Zack knew what she was doing, and yet he didn’t even consider refusing. He simply did as Camilla desired. He moved his tongue over her fingers. He licked and sucked as she moved them in and out of his mouth and the handjob she offered ensured that he felt only the purest pleasure.</p><p>“You’re going to make an excellent cocksucker, Zachary,” Camilla whispered.</p><p>Zack moaned. He didn’t want to. It was deeply humiliating to feel any sort of pleasure as Camilla uttered those words, and yet he couldn’t help himself. There was something about her delivery and the feel of her warm breath against his skin as she said it that thrilled him. There was also the intense joy of her hand moving up and down his shaft.</p><p>“Maybe I’ll make you suck cock before you move out, Zachary,” Camilla said as she stroked him faster. “Maybe it will be a lovely gift for my daughter to make you submit to such a humiliating act before you begin the next step on your journey together. Would you like that, Zachary? Would you like to suck cock for me?”</p><p>Zack couldn’t answer, of course. Not with three fingers pumping in and out of his mouth. He couldn’t help from cumming, either. With Camilla’s fingers in his mouth and her words still rattling around in his head, Zack had an orgasm that left his body trembling with pleasure. His cum shot high in the air with some landing on the kitchen table, some on his thighs, and some on the floor.</p><p>Camilla pulled her fingers from his mouth, gave Zack a soft kiss, and asked, “Did you enjoy that, Zachary?”</p><p>“Very much so, yes,” he replied. “Thank you.”</p><p>“You’re welcome,” Camilla said as she scooped up the cum that had landed on the table, leaned back, and rubbed it over her pussy lips. “Now get on your knees and clean your mess off my pussy. When you’re done, you can make me cum.”</p><p>Zack slid off the chair and onto his knees. He scooped the cum off his thighs, added it to the mess Camilla had already transferred to her pussy lips, and then leaned forward to get busy cleaning.</p><p>“That’s very good,” Camilla said as she ran her fingers through his hair. “I’m very pleased my daughter is in love with you, Zachary. I’m certain that you’re going to make her very happy, that’s all I care about.”</p><p>Zack offered Camilla the pleasure she sought and tried his best to keep from wondering if she actually planned on making him give a blowjob before he moved out or if she was simply teasing.</p>
