It arrived two days after our last appointment and I felt genuinely excited as I opened it.</p><p>It wasn’t the notion of fucking the toy that I found the most exciting. It was the idea of making Myles watch. It was what the toy represented (cuckolding him, of course). It was that I’d been instructed to purchase the toy by Peter, whom I’d been having rather lurid fantasies about.</p><p>I brought Myles and my new toy to the bedroom and we both got naked. I thought it would be fun to tease him a little, so I had Myles get hard and then handed him the toy.</p><p>“Hold it next to your cock,” I said.</p><p>He did so and of course his cock couldn’t compare to the toy. It wasn’t quite double his length, but it was close. The thickness is what really made a difference, though. It was amazing how much thicker the toy looked compared to Myles’s cock.</p><p>“Is this the kind of cock you want?” Myles asked.</p><p>“That’s the kind of cock every woman wants, Myles,” I said, which was mostly true. Size does matter, but the way a cock is used is important too.</p><p>He looked up at me with this mixture of lust and anxiety in his eyes, like we were about to cross a line that we couldn’t come back from.</p><p>“Things changed the moment we made that therapy appointment, Myles,” I said. “The second we sat down on Mistress Brooke’s couch our marriage changed. This toy is the next step, but everything that happens from here on out was destined to happen. It can’t be stopped. I’m going to cuckold you. Peter will be the first to fuck me, but he won’t be the last. I need a man that can give me what you can’t, which you know goes beyond the size of your cock.”</p><p>I think it was the part about me needing a man that could give me what Myles couldn’t that filled him with desire. I saw it on his face. I saw the anxiety disappear. I saw it replaced with a pure-seeming kind of lust.</p><p>“I love you,” he said.</p><p>I smiled, took the toy from Myles, and hopped into bed. I spread my legs and pointed between my thighs. I didn’t even have to say anything for Myles to get between my legs and lick me.</p><p>“Get me nice and wet, Myles. This cock is a lot bigger than what I’m used to having in my pussy, after all,” I said as I reached down and ran my fingers through his hair. It was such a small gesture, but it felt good, especially when I lightly gripped his hair and held his head in place. I felt powerful in a way I really liked.</p><p>“You’re going to do this some day before another man fucks me,” I explained. “You’re going to do as a cuckold should and prepare my pussy for someone else to fuck. You’re going to get me nice and wet so a big, thick cock can dominate me and make me cum like I need.”</p><p>Myles’s tongue worked faster and he inserted a finger into me to work my g-spot a little. It was quite lovely and it absolutely got me wetter.</p><p>I got a little lost in the pleasure of it and started thinking about Peter fucking me. I imagined his big cock sliding into my soaking wet pussy as he took me from behind. I’m not sure why, but that was the position that popped into my head. I felt his hands on my hips as he slowly filled me while I was positioned on my hands and knees. I felt my pussy stretching out around him. It was glorious.</p><p>“I need to cuckold you, Myles. I wasn’t sure about it initially, but I know now. I know that I have to give my body to another man to have the kind of orgasm I truly crave. I know that I need someone else to provide me with what you’ve always failed to give me,” I said.</p><p>I saw Myles reach between his legs to stroke his cock and I quickly pulled on his hair and lifted his head from between my legs.</p><p>“No masturbating until you’ve been given permission,” I said. “Do you understand?”</p><p>Myles nodded like a boy that had been chided, and in truth I suppose that’s exactly what he was in that moment.</p><p>It turned me on. That might sound horrible, but it really turned me on to take control like that, though it’s also possible that what turned me on was the way he did as he was told without hesitation.</p><p>I pulled his head back between my legs and he resumed licking my pussy with his hands resting on my thighs and moving over my soft skin.</p><p>“That’s good, Myles. Show me that you know how to be a good boy for your wife,” I said.</p><p>Again I felt a beautiful surge of lust. It was so wonderful to take control of him. It was such a thrill to have him do as he was told. It filled me with confidence in a way I loved.</p><p>“Would you like to watch me fuck this beautiful cock?” I asked as I held up the toy.</p><p>Myles looked up from my pussy and nodded as he licked my juices from his lips.</p><p>“Would you like to play with your cock while you watch?” I asked.</p><p>Myles nodded again.</p><p>“Back up just a little bit,” I said.</p><p>Myles moved back just enough to give me room to play between my legs. I wanted him nice and close so he could see my pussy open around the toy. I wanted him to be able to hear how wet I was, too.</p><p>I rubbed the head of the toy around my pussy lips to get it nice and wet and then pushed it inside. I closed my eyes and imagined Peter between my legs as the toy pushed inside me.</p><p>“Does it feel good?” Myles asked.</p><p>I opened my eyes and smiled at my husband as he played with his cock and watched me slowly fuck the toy.</p><p>“Is that really the question you want to ask?” I replied.</p><p>Myles looked up at me and smiled sheepishly. He stroked his dick a little faster and asked, “Does it feel better than my cock?”</p><p>“Yes, it does,” I answered. “And this is only a dildo. When there’s a dominant man attached to a cock like this I can’t imagine how good it’s going to feel.” I fucked myself a little faster and moaned. “I do know that it’s going to mean I won’t have much use for your cock anymore.”</p><p>Peter had talked some about how to train Myles to be a cuckold. He’d said it was effective to deliver certain messages while Myles was in a state of great arousal as it would help him be eternally aroused at the idea of being a cuckold. Based on the look on his face as I informed him of just how useless his cock would be to me, Myles was eager to experience the arousing pleasures of me having great sex with another man.</p><p>“You like that, don’t you?” I asked. “You like that another man is going to replace you between my legs. You like that I’m going to be someone else’s submissive slut, don’t you?”</p><p>I actually had an orgasm just a few seconds after asking that question. It was a really good orgasm, too, and I’m almost certain it was the idea of being a submissive slut for someone that did it. Even writing it now turns me on a little.</p><p>I buried the toy in my pussy as my body convulsed with pleasure. Myles groaned as he watched me cum on what was quite literally a bigger cock than the one he was eagerly stroking.</p><p>“Holy shit,” I said. “That was incredible.”</p><p>Myles was still busy stroking his cock as I began to slowly slide the dildo in and out of my pussy.</p><p>“Are you going to cum?” I asked.</p><p>He nodded.</p><p>“I want you to cum on the toy,” I said.</p><p>Myles got on his knees and stroked his dick in front of me as I fucked the toy.</p><p>“Let me know when you’re going to cum,” I said.</p><p>Myles nodded and I fucked the toy a little faster. He watched my pussy lips stretch out from above me and then said, “I’m gonna cum!”</p><p>I pulled the toy out and held it in front of his cock. His aim was pretty good as most of his cum landed on the dildo and only a little got on my stomach. His orgasm seemed exceptionally good, too, as he had to put his hand on the bed to keep himself from collapsing as the pleasure washed over him.</p><p>I took the cum-soaked toy and slid it back inside me. I liked the idea of Myles’s cum filling me without him actually being able to shoot it directly inside me. He was lost in his own little world, but I fucked myself to a second orgasm as I again thought of Peter taking my pussy and making it is. I couldn’t wait to be his submissive slut.</p><p><strong>Myles</strong></p><p>“Was it a good orgasm?” Mistress Brooke asked.</p><p>I smiled before saying, “It was. It was really good, actually.”</p><p>“Do you have a sense of what made it a good orgasm?” she asked.</p><p>“I think it was the dirty talk, honestly. Or, I guess it was watching her fuck the big dildo combined with the dirty talk. And the domination. I guess it was all of it. I mean, it was really intense and Molly didn’t seem to have any problem taking control, which I loved,” I explained.</p><p>Mistress Brooke smiled and said, “It sounds like your wife is well on her way to becoming the woman of your dreams, Myles. It’s important that you show her the proper respect and love from this point forth. After all, she has to juggle dominating you and submitting to the alpha males she’s going to offer herself to and that can be quite a bit more challenging than what you’re being tasked with. Plus, as a good submissive you should always put the needs of your dominant partner above yours.”</p><p>“Yes, of course,” I said.</p><p>“I’m glad you feel that way, Myles, but I’m quite certain you’re not prepared for what that’s going to mean eventually. That’s okay, though. Few submissives ever really are. A little bit of light punishment is usually enough to correct any objectionable behavior, though. I’ll make sure to have Peter talk to Molly about that in case you decide you’re not going to put your wife’s needs above yours.”</p><p>I felt a little uncomfortable with the idea of Molly punishing me, in large part because Iimagined it would likely be painful. I knew it was almost a certainty that I’d screw up, which meant it was almost a certainty I’d receive the punishment Mistress Brooke was talking about.</p><p>“I don’t want to disappoint her,” I said.</p><p>“I know you don’t, Myles, and our sessions are going to be focused on making you into a good submissive for your wife, but it’s inevitable that you’re going to behave in a way that disappoints her and you’ll be punished for that. Don’t worry, though. The punishments are for your own good. They make you a better submissive. You needn’t be nervous,” Mistress Brooke explained.</p><p>“Okay,” I said, though I still felt a touch of anxiety about it.</p><p>“Do you feel prepared for the eventuality of being cuckolded, Myles? It’s already happened to a certain extent as Molly has offered Peter her mouth. It will feel different when he fucks her, though. When his cock provides her with an orgasm it will change your marriage. Do you feel like you’re ready for that?” Mistress Brooke asked.</p><p>“I honestly don’t know,” I said, which was the truth. I’d fantasized about it. I’d had great orgasms to the notion of being a cuckold, but I had no idea what it was going to be like when it actually happened.</p><p>Mistress Brooke leaned forward and exposed a bit of cleavage, which I couldn’t help but stare at. She was so beautiful and she carried herself with such confidence that I found her utterly irresistible.</p><p>“After Peter fucks Molly for the first time she’s going to be completely enamored with him. He’s going to give her an orgasm unlike any she’s ever experienced. In all likelihood it’s going to be multiple orgasms. Once she cums like that she’s going to want more. She’s going to be desperate for him. She’s going to want to give herself to him in every imaginable way,” Mistress Brooke explained.</p><p>As she talked, I got turned on. It all sounded good to me.</p><p>“What many cuckolds are unprepared for is how sudden and overwhelming the change is. Molly will not want to fuck you after Peter fucks her. She will likely experience a period of time where she doesn’t really care to make you cum at all because she will have learned just how underwhelming you are as a lover. She knows it now, but it’s going to be different when she has someone far superior to compare you to,” Mistress Brooke said.</p><p>I hadn’t really considered that part of it. I knew the sex would be better – Molly needed to be dominated and I couldn’t do that for her – but I hadn’t thought about how much better it would be. Was it possible that Peter was that much better?</p><p>“The truth is, there’s no way to prepare for it,” Mistress Brooke said. “Hopefully you won’t be as shocked as many cuckolds are, but there will be an adjustment period. Plus, you may find a certain measure of pleasure in Molly’s eagerness to have you worship her body and serve her needs in other ways. It’s also important to remember that she will tend to your sexual needs again before long. She’ll just need a bit of time to adjust, and you will too.”</p><p>I couldn’t stop thinking about Peter fucking Molly so well that it changed the way she thought about me. It was intoxicating in that moment. It was like what I’d witnessed as she fucked the toy, only a hundred times more potent.</p><p>Mistress Brooke pulled me from my revelry with a question. “Have you ever sucked cock?”</p><p>“What? No. No, I haven’t,” I said.</p><p>A delighted smile crossed her face as she said, “That’s quite likely to change.”</p><p>“What? Why?” I asked.</p><p>“Because you’re a submissive, Myles, and your wife is going to transform into a wonderfully dominant woman and she’s quickly going to realize that making you suck her lover’s cock is a splendid way of reinforcing your submissive nature. After all, once you’ve had her lover’s dick in your mouth it will be quite difficult to insist that you’re more of a man than he is, won’t it?” Mistress Brooke asked.</p><p>“I…well, I…I just never thought about…I don’t…I’m not gay,” I said, though obviously my mind could barely string together more than a few coherent words.</p><p>“Your sexuality has nothing to do with it, Myles,” Mistress Brooke said as she stood up and pointed to the floor in front of her. “On your knees, here.”</p><p>I moved to my knees where she’d directed and watched my beautiful therapist walk to her desk, pull open a drawer, and remove a long, lifelike dildo.</p><p>She sat down once more and said, “Crawl to me, Myles.”</p><p>I crawled towards her with my eyes on the dildo. I strongly suspected I’d be sucking on it.</p><p>“As a submissive, your sexuality doesn’t exist. What you’re attracted to and what turns you on is of no consequence. All that matters is what your mistress wants you to do. Therefore, if Molly demands that you suck her lover’s cock to get it hard for her pussy, you’ll do it. You’ll give him a wet, passionate blowjob and make sure he’s throbbing for her cunt because it’s what she wants you to do. You don’t need another reason,” Mistress Brooke said.</p><p>She lifted the dildo and rubbed it around my lips as her eyes locked onto mine.</p><p>“Open your mouth, Myles,” she said.</p><p>I did as I was told and a moment later I had a rubber cock in my mouth. The underside moved along my tongue until I couldn’t take anymore and then Mistress Brooke said, “Suck the cock, Myles.”</p><p>I was caught up in a submissive trance. As much as I found the idea of sucking cock appalling, I didn’t have a cock in my mouth. I had a toy in my mouth and I had a beautiful domme sitting a foot away demanding that I give a blowjob. I did as I was told.</p><p>“That’s a good boy,” Mistress Brooke said as I moved my mouth back and forth on the toy. “See? It’s not so hard to be a cocksucker for your mistress. All you have to do is open up and do as you’re told. It’s like sucking a much longer, thicker lollipop. It doesn’t make you gay to give a blowjob, Myles. It just makes you a submissive because you’re doing it for your mistress. You need to get used to it, too, because you will absolutely be sucking cock for Molly when she comes into her own as your wife and mistress.”</p><p>Part of my brain was trying to fight the notion, but there was another part that knew it was going to happen. Of course it was. Mistress Brooke knew what she and her husband taught the couples they trained. She knew that Peter was going to tell Molly to make me suck cock at some point and I knew I wasn’t going to refuse.</p><p>“Take the toy, Myles. Fuck your mouth with it,” Mistress Brooke said.</p><p>I took the toy from her and pumped it in and out of my mouth as she stood up and stripped to her underwear and sat down once more.</p><p>“You’re going to be a very good cocksucker, Myles,” she said. “I can see it in your technique and your passion.”</p><p>I felt oddly thrilled by the compliment.</p><p>Mistress Brooke took the toy from my hand and pulled it out of my mouth before sitting back, pulling her panties to the side, and sliding it into her pussy. For the second time in a handful of days I was watching a beautiful woman fuck herself with a big dildo.</p><p>“Thank you for getting the cock all wet for my pussy,” Mistress Brooke said as the toy slid in and out of her. “Would you like a reward, Myles?”</p><p>I nodded.</p><p>“Would you like to play with your cock as you watch me fuck this toy?” she asked.</p><p>I nodded again.</p><p>“You can do so, but on one condition,” she said.</p><p>“What condition?” I asked, dreading whatever the answer was going to be.</p><p>“You must cum into a condom and submit to me feeding you some of your load when you’re done,” she said.</p><p>My cock was hard and I’d spent most of the session in a state of heightened arousal, so the idea of consuming my cum didn’t actually seem all that off-putting in the moment.</p><p>“Okay,” I said.</p><p>“You’ll find condoms in the second drawer down in my desk,” Mistress Brooke said. “Go get one.”</p><p>I rushed to the desk, grabbed a condom, and returned to the floor. I pulled my pants down, tore open the condom, and rolled it down my cock before stroking furiously as I watched Mistress Brooke fuck herself.</p><p>She used a finger to pleasure her clit while pumping the toy in and out of her pussy and her moans soon filled the room.</p><p>“Do you know what your wife is doing right now, Myles?” she asked.</p><p>“No,” I said.</p><p>“She’s sucking my husband’s cock,” Mistress Brooke said. “She’s riding that dildo she teased you with and she’s worshiping my husband’s big dick like a slut. He said he was going to feed your wife a load of cum before their session ended and he was going to do it while she fucked her cunt with that big toy until she was a quivering mess of pleasure.”</p><p>I felt an intense sense of jealousy, mostly because I wanted to be watching Molly suck Peter’s cock. I wanted to watch her get lost in that pleasure. I wanted to see her cum while she was giving head to someone else.</p><p>“He’s going to make her his submissive slut, Myles. Someday soon he’s going to fuck your pretty young wife and changed your marriage forever. He’s going to make you a cuckold. He’s going to show your wife what she’s been missing since she said yes to marrying a man like you,” Mistress Brooke said.</p><p>I felt my orgasm approaching as this deep, intensely satisfying sense of pleasure spread through my body. It was unbelievably hot.</p><p>“Cum for me, Myles. Cum like a cuckold. Spill your load into that condom and get ready to eat it. Cum in the condom while my husband cums down your wife’s throat,” Mistress Brooke said.</p><p>She closed her eyes and we climaxed almost simultaneously. My cum spurted into the condom, filling the tip while Mistress Brooke buried the toy in her pussy and had an orgasm that was absolutely thrilling to watch.</p><p>“Take the condom off,” she said.</p><p>I pulled the condom off my cock and handed it to Mistress Brooke. She smiled and dipped her fingers into it, pulling them out only when they were coated in my cum.</p><p>“Open up,” she demanded.</p><p>I opened my mouth and she pushed her fingers into my mouth. A moment later the salty taste of my seed exploded on my tongue. I gagged at first and Mistress Brooke laughed.</p><p>“This is something you’ll have to get used to,” she said. “As a cuckold you’re going to be eating a great deal of cum. Whose cum you eat will be your wife’s choice, but I expect you’ll be consuming your own and the loads of the men she welcomes into her body.”</p><p>Mistress Brooke dipped her fingers in my cum once more and pushed them into my mouth.</p><p>“So you’re going to be a cocksucker and an eager cum eater,” she said. “You’re going to go places you never imagined and you’re going to do all of it willingly, like a good submissive. Do you understand?”</p><p>My mouth was still filled with her cummy fingers, so I nodded eagerly.</p><p>“Swallow,” Mistress Brooke said as she pulled her fingers from my mouth.</p><p>I swallowed my cum and she smiled, which filled me with joy.</p><p>“Put your cock away. We’re going to witness the end of your wife’s session with Peter,” she said.</p><p>I did as I was told and we left the room.</p>
