Are you absolutely certain you want to do this?” Emily asked as she stepped into a black lace bodysuit she’d bought just for the occasion.</p><p>Luke was amazed at his girlfriend. In such a short span of time she’d undergone a remarkable transformation. The confidence she’d developed after fucking Jameer was at the source of all of it and he loved it.</p><p>“Yes, I’m sure,” Luke said. He didn’t feel the slightest bit of hesitation. To him, there wasn’t much of a difference between watching Emily have sex with Jameer and the two of them doing it while he wasn’t around. Plus, he really wanted to see just how different it was.</p><p>Emily looked at her lingerie-clad body in the mirror and smiled. She ran her hands over the lace and between her legs. Luke could see the arousal in her eyes. He thought she might masturbate right there.</p><p>“It’s different with him,” Emily said as she turned to her boyfriend. “You might be surprised at just how different it is.”</p><p>“How is it different?” Luke asked as Emily straddled him on the couch. His cock was already stiff, but he felt arousal surge through him as she gently ground her hips over his lap.</p><p>“It’s me that’s different,” she said before leaning down to lightly kiss his lips. “I’m going to be different than you’ve ever seen me. I’m going to get lost in the pleasure of having his big black cock inside me.”</p><p>He was getting used to Emily talking like that, but Luke still couldn’t believe it was his formerly shy, buttoned up girlfriend openly discussing her love of Jameer’s cock.</p><p>It looked like she was already getting lost in the lust of fucking her coworker. Emily’s hips moved faster over his crotch and her eyes closed as she moaned. Luke reached up and played with her perky little breasts in the black lace lingerie.</p><p>“I’m going to cum so much harder on his cock than I’ve ever cum on yours,” she added.</p><p>Luke knew it was unusual to be so aroused at the idea of his girlfriend cumming hard on someone else’s dick, but he didn’t care. He loved Emily and he loved that she was fucking Jameer. Nothing else mattered.</p><p>“I’m ready,” Luke said as he pulled her lips to his for a long kiss. He grasped her ass cheeks and squeezed hard as her tongue darted in and out of his mouth.</p><p>“Good, because he’ll be here soon,” Emily said. “And once he comes through that door, he’s not leaving until I’ve gotten my fill of his big black cock.”</p><p>Luke’s cock throbbed at the dominant edge in her voice. She was telling him how it was going to be. There was no leeway.</p><p>“So if you get uncomfortable, you’ll have to leave, because I’m not sending Jameer home until he’s made me cum as many times as I want. Do you understand?”</p><p>“Absolutely,” Luke said. He couldn’t help but smile. He was thoroughly delighted at how eager his girlfriend was to cum on another man’s big black cock.</p><p>The buzzer sounded and Emily climbed off of Luke to let Jameer in.</p><p><br></p><p>As Emily walked towards the front door she felt the heat and wetness of desire between her legs. She was more excited about cuckolding Luke than she expected. She wasn’t the slightest bit nervous about it, either. He seemed thrilled to have the chance to watch her cum on Jameer’s big black cock and that was all that mattered.</p><p>A few moments after buzzing Jameer in, there was a knock on the door. Emily opened it up and stood there in her skimpy black lace bodysuit.</p><p>“Damn, now that’s what I like!” Jameer said as he took a moment to ogle her with the door wide open.</p><p>Emily stepped back as he stepped into the apartment. The door closed behind Jameer before he took her into his arms and they kissed. An involuntary moan escaped her lips as Jameer’s hands deftly played with her perky breasts.</p><p>“Is your man ready for this?” Jameer asked as his hands moved to her ass.</p><p>“He is,” Emily said as she reached between Jameer’s legs and grasped his cock through his jeans.</p><p>“Are you ready for this?” he asked.</p><p>Emily smiled and said, “I need your cock inside me and I need him to watch. I want him to see what it looks like when I have the kind of sex I need.”</p><p>Emily wanted Luke to have fun. She wanted him to experience his cuckolding firsthand and have a great orgasm.</p><p>More than that though, she wanted him to watch because she was planning for the future. She still wanted to marry Luke, but she needed him to accept that she wasn’t going to be a faithful wife. She was going to cuckold him. She was going to have other men to meet her sexual needs, or at least her need for big cock sex. This was her chance to see if Luke could handle that.</p><p>Emily kissed Jameer and then took him by the hand and led him past Luke and into the bedroom.</p><p>“Come, Luke. It’s time for you to witness your cuckolding,” she said. Her voice was soft but commanding.</p><p><br></p><p>Luke stood up and followed his girlfriend and Jameer into the bedroom. He sat in the wooden chair they’d set near the foot of the bed.</p><p>Emily smiled at him. It seemed that she found his willingness to do as he was told without argument quite pleasing.</p><p>Luke watched as Emily kissed Jameer eagerly. Jealousy surged through him. He fought off a brief urge to stand up and pull the two of them apart. He’d prepared himself to feel jealous. He knew it was impossible to avoid and that it was going to be a part of his sex life going forward.</p><p>Emily turned to him and smiled as Jameer’s hand moved between her legs. “Are you ready for me to cuckold you?” she asked.</p><p>“Yes,” Luke said.</p><p>“Good. Then take your cock out,” Emily said to Luke as she unzipped Jameer’s pants. “You may masturbate, but you’re not allowed to cum until I say so.”</p><p>Luke couldn’t help but stare at Jameer’s big black cock as he pulled down his pants and freed his considerably smaller erection. It was the first time he’d seen it, and it was even bigger than he’d pictured.</p><p>“You can see why I prefer his cock, can’t you?” Emily said.</p><p>Luke’s cock had never been harder, and yet he felt an uncomfortable sensation as he watched his girlfriend fall to her knees in front of another man after declaring her preference for the big black cock that was no inches from her mouth.</p><p>Emily stroked Jameer’s massive dick as she continued to look over at Luke. “Do you want to watch me suck his cock?” she asked.</p><p>Luke nodded. He couldn’t bring himself to say anything, but he desperately wanted to watch Emily take the massive black dick in her mouth.</p><p>Emily smiled and turned her gaze towards Jameer. She looked up at him as her tongue licked from the base of his shaft to the head. She took the drop of precum at the tip into her mouth and then wrapped her lips around his massive black cock.</p><p>Jameer moaned as Luke watched his girlfriend blow another man. He had to take his hand off his cock. He would have cum otherwise.</p><p>Ever since Emily had suggested he watch, Luke had imagined this moment over and over, but seeing it in person was so much more arousing than he’d expected. His mind felt utterly overwhelmed with a crazy mixture of emotions.</p><p>Emily worshiped the big black cock from her knees for far longer than Luke expected. Much to his surprise, she seemed to genuinely love having the massive dick in her mouth. She even sucked on his black balls while stroking the thick head with her skilled fingers.</p><p>Luke couldn’t stave off a sense of jealousy as he witnessed her lust for Jameer’s cock. He couldn’t help but think that she’d never sucked his cock like that. That was quickly followed by a wave of humiliation. It seemed clear that she was sucking him like that because of the pleasure Jameer’s cock offered her when they fucked.</p><p>“I think your man likes watching you suck my cock,” Jameer said as Emily released his big black balls from her mouth.</p><p>“His cock looks awfully hard, doesn’t it?” Emily said as she stood up and walked towards Luke.</p><p>He was surprised when she aggressively kissed him. Her tongue pushed past his lips and into his mouth. He tasted Jameer on her. It was unmistakable. Luke wasn’t sure if it was the black man’s cock or balls that he was tasting. Perhaps it was both.</p><p>“I’m going to cuckold you now,” Emily said as she grasped the arms of the chair. “Do you want that? Do you want Jameer to fuck me?”</p><p>“Yes,” Luke said as he nodded vigorously.</p><p>Emily leaned forward and kissed him. “Say it.”</p><p>“I want him to fuck you,” Luke said.</p><p>Emily smiled, and then her eyes rolled back in her head as she groaned in a way Luke had never heard before. Jameer was fucking her. He was pushing his cock into her pussy from behind and Luke was watching in the most erotic, up close and personal way.</p><p>“It feels so fucking good,” Emily said as she closed her eyes and bit her lower lip. “It feels so fucking good!”</p><p>Her hands moved to Luke’s bare thighs. With each thrust, Emily braced herself against him. His girlfriend was getting fucked and he was sitting there watching it all. He was a cuckold now. There was no denying it.</p><p>Emily fingers moved closer to his cock as Jameer pounded her from behind. She moaned. She groaned. She screamed. She let both the men in the room know exactly how good it felt to get fucked by Jameer’s big black cock.</p><p>Eventually, her fingers found Luke’s stiff dick. She stroked him slowly and with a soft grip. Any harder and he would have cum. Instead, Luke remained in a state of intense pleasure, right on the edge of orgasm.</p><p>Emily looked down at his cock and then into Luke’s eyes. “He’s so much bigger than you,” she said. “His cock feels so much better inside me than yours ever has.”</p><p>Luke felt the most intense surge of pleasure he’d ever experienced. He tensed up. It was the beginning of an orgasm, but Emily swiftly let go of his cock before he actually climaxed. </p><p>“You love this, don’t you?” she asked. “You love being a cuckold.”</p><p>“Yes,” Luke admitted, though he couldn’t bring himself to look her in the eye.</p><p>Emily lifted his chin with her fingers and smiled at him. She pulled his lips to hers and they kissed as Jameer fucked her from behind.</p><p>“I love you,” she said before standing up and letting Jameer’s cock fall from her pussy.</p><p>Luke watched from his chair as they moved to the bed. Jameer got on his back and Emily straddled him. She reached down and guided the big black cock into her pussy, and for the first time Luke noticed they weren’t using a condom.</p><p>He saw his petite girlfriend’s tight pussy stretch out around Jameer’s massive black cock. He heard Emily moan as she sank down onto the other man. He saw Jameer’s large black hands grasp her milky white ass. He watched them fuck.</p><p>Luke was mesmerized. It was an entirely different experience. He couldn’t keep his eyes off the beautiful sight of Emily’s cunt lips stretching out around the big black dick inside her. That’s when he truly saw the difference. Jameer was genuinely huge.</p><p>Soon after she climbed on his cock, Emily had her first orgasm. First Luke noticed how she seemed to be trembling as she rode Jameer. Then she tilted her head towards the ceiling and swiftly moved her hips back and forth over the other man. Then, finally, she let out a long, slow moan that got louder as her orgasm approached.</p><p>As she came, Emily collapsed on top of Jameer. He wrapped his arms around her and kissed her neck and cheek gently. Afterwards, she simply laid on top of him with his big black cock buried inside her. Again, Luke felt intensely jealous. Someone else had just made his girlfriend cum and it seemed like she’d forgotten he was even in the room as it was happening. Of course, that also made his dick throb.</p><p>When they disentangled, Emily gave Luke a quick glance before moving to her back. Jameer took his place between her legs and soon enough he was inside her again.</p><p>Emily wrapped her legs around him and Luke witnessed another round of intense fucking between his girlfriend and her black lover. Again he saw how hard Jameer fucked her and how much she seemed to love having his big black cock buried deep inside her.</p><p>Luke slowly stroked his dick as he watched them fuck. He admired the power behind Jameer’s thrusts and the way their bodies seemed to meld together as they had sex.</p><p>“Cum inside me,” Emily moaned as she wrapped her arms around Jameer and pulled him close.</p><p>Luke knew it was coming. He knew they were having bareback sex because she wanted Jameer to cum inside her. He knew she was on birth control and that she must have trusted the man fucking her to be clean. He knew he wanted to see it happen, too.</p><p>The sex took on a slow, almost romantic tone as Jameer’s orgasm approached. Emily kissed him and ran her fingers over his back. She held him close. Seeing the color contrast of their skin was intensely sexy as Luke barely touched his cock. He was afraid he’d cum otherwise.</p><p>“Cum inside me, baby,” Emily said once more.</p><p>Soon thereafter, Jameer groaned and pushed the full length of his cock into her pussy. He held it there as Luke watched another man cum in his girlfriend. He couldn’t believe how intensely pleasurable it was to witness it. He couldn’t believe how badly he wanted to cum.</p><p>When Jameer pulled out, a trickle of thick white cum followed. Luke watched them kiss and caress each other in a surprisingly tender manner before Jameer slipped out of the bed and walked by him and into the bathroom.</p><p><br></p><p>As Jameer walked into the bathroom and turned on the shower, Emily looked at her boyfriend. His noticeably smaller cock was rock hard and slick with precum. She was struck by a naughty idea.</p><p>“Come here,” she said to Luke.</p><p>Emily kept her legs spread wide open, giving him no choice but to lie down between them. She kissed him softly and pulled his body on top of hers.</p><p>Instead of telling him to do it, Emily reached between their legs and guided Luke’s cock into her cum-filled pussy.</p><p>“Fuck me,” she said.</p><p>Emily knew he wouldn’t say no. She knew he’d thrust into her cum-filled pussy, which is exactly what he did.</p><p>He pumped her hard and fast, just as Emily knew he would. He’d spent too long being on the edge of orgasm. He couldn’t hold back, or try and make love to her.</p><p>Emily smiled as she pulled Luke close to her and whispered, “Jameer stretched me so much that I can’t even feel your little dick.”</p><p>Luke let loose a loud groan and came inside her. She wrapped her legs around him and pulled him close, just as she’d done with Jameer.</p><p>“That was unbelievable,” Luke finally said. “Thank you.”</p><p>Emily smiled. If he was thanking her after his orgasm that meant he had truly enjoyed himself and the likelihood of any bad feelings was minimal.</p><p>She kissed Luke softly and he pulled out of her. Emily felt the cum of two men running out of her. The notion made her smile.</p><p>“I hope you’re eager for more, because Jameer never fucks me just once,” she said.</p><p>“I can’t wait,” Luke said with a smile.</p><p>“Good.” Emily kissed him again and then walked to the bathroom. “I’m going to hop in the shower with Jameer. I expect we’ll be ready for another round by the time we’re done.”</p><p>The giddy look on Luke’s face was exactly what Emily wanted to see. He was definitely a cuckold.</p><p>The End</p>
