Ever since the phone sex with Emily something had been bothering him, and on the long plane ride home it was all he thought about.</p><p>It was while he was staring out the window that the reality of his worry set in: He thought Emily was sleeping with someone else. He didn’t have any proof and it could have just been his insecurity cropping up, but it felt realistic.</p><p>The way she moaned while they had phone sex was different than he’d ever heard he moan, and Luke knew it wasn’t because he’d unlocked some wilder version of his girlfriend with a week’s worth of intense oral sex and foreplay.</p><p>He figured she had to be moaning like that because someone else was fucking her while they were on the phone. Once the thought entered his mind, Luke fixated on it. It was all he could think about for the rest of the flight and it was in his head as he climbed into the Lyft.</p><p>The crazy thing was, Luke didn’t find himself trembling with rage. Perhaps it was because he hadn’t confirmed that his suspicions were true, or perhaps it was something else he couldn’t begin to understand.</p><p>When the Lyft pulled up in front of their apartment, Luke considered not getting out. He considered ordering another ride and just running away from the potentially devastating conversation that would happen once he got inside.</p><p>He overcame his fear and walked slowly up the stairs, through the front door, and up another set of stairs. He pushed his key in the lock, opened the front door of their apartment slowly, and saw Emily sitting at the table with a somber look on her face.</p><p>She smiled as Luke walked in and shut the door behind him. When he approached Emily stood up and took him into a tight hug, though it wasn’t the same kind of joyful embrace that she usually took him into when they were seeing each other after a long time apart.</p><p>“What’s wrong?” Luke said. He decided to take the pull-the-band-aid-off approach.</p><p>Emily’s shoulders slumped and she sat at the kitchen table. She ran her fingers over the white porcelain coffee cup sitting in front of her and pushed her glasses up her nose before looking up at Luke.</p><p>“I slept with someone else,” she said.</p><p>Luke felt his knees wobble as the news hit him. Despite it being a confirmation of his suspicions, it still hurt. He reached out and grasped the edge of the table to maintain his balance and sat in the chair across from Emily.</p><p>“Were you with him when we had phone sex?” Luke asked. It was the only thing he could think about. He’d suspected something was different when they talked and he needed to know.</p><p>“Yes,” Emily said as she looked down at the table.</p><p>“Who is it?” Luke asked.</p><p>“Jameer, from work,” Emily replied without hesitation.</p><p>Despite his desire to be furious with her, Luke couldn’t help but be impressed that Emily was being so straightforward with him.</p><p>“I’m sorry,” she said, though Luke didn’t detect as much remorse in her voice as he thought he might.</p><p>“So it was really him that made you cum so hard while we had phone sex. You weren’t thinking about me at all, were you?” Luke asked.</p><p>“No, I wasn’t,” Emily admitted.</p><p>A hint of anger crept into Luke’s voice as he said, “And you’ve fucked him more than once, I take it?”</p><p>“Yes, I have,” she said while looking up at Luke.</p><p>He expected to see sadness in her eyes. Instead, he saw defiance. It confused him. Why wasn’t she more remorseful about this? Why wasn’t she pleading for forgiveness?<br><br> </p><p>“How many times?”</p><p>“I’ve lost count,” Emily replied.</p><p>Luke was certain he saw the slightest smile from his girlfriend as she informed him she’d fucked Jameer so many times she’d stopped counting.</p><p>He knew that was the moment he was supposed to get furious. She was setting him up for it. It was like she was purposefully taunting him and daring him to get angry at her. He couldn’t muster it though.</p><p>Instead, Luke felt defeated. It seemed clear that Emily had found someone that could provide her with something that he couldn’t.</p><p>Luke knew his next question was insane. He knew it would make him miserable. He knew it might torture him for years to come. He couldn’t help himself though.</p><p>“Is he better than me?” he asked.</p><p>Emily looked up and again it looked like her mouth curled into the tiniest smile. “Yes,” she answered.</p><p>“How?” Luke asked, though his voice wasn’t angry or confrontational. He was curious.</p><p>Emily studied his face for a moment before answering. “He’s bigger and more experienced. He knows when to make love to me, when to fuck me, and when to take what he wants from me.”</p><p>Her answer was concise and cutting. Luke had met Jameer once, and now the exceptionally handsome young black man had fucked his girlfriend.</p><p>An image of Jameer and Emily having sex popped into Luke’s head. The lusty words she’d uttered during their phone sex session played in his head. He imagined Emily saying them as Jameer fucked her. He imagined exactly what had happened.</p><p>He couldn’t sit at the kitchen table and stare at his girlfriend anymore. He wanted to leave, to run until the city was behind him. He couldn’t do that, though. He had to stay. He had to confront this. He couldn’t stay at the table, though. He had to move.</p><p>Luke shot up and walked out of the room. “I just can’t,” he said.</p><p><br></p><p>Emily watched Luke stand up and leave, though she didn’t quite believe the anger he was trying to exude. In fact, she was a little confused that he didn’t seem more enraged.</p><p>She was also quite certain Luke had a little bit of an erection when he walked past her. Not fully erect, but there was definitely something happening between his legs.</p><p>Emily knew Luke well enough to recognize that there was a flash of lust in his eyes when she detailed how Jameer was better than him.</p><p>She knew it was dangerous and potentially cruel to answer him honestly, but Emily had resolved to be as clear and concise as possible with Luke and to answer every question he asked. She figured this was the beginning of the end of their relationship and while she felt terrible about how it had all unfolded, she didn’t feel the kind of regret she thought she should.</p><p>After Jameer had left that morning, Emily told herself that she knew a long term relationship with him wouldn’t work, but that she also knew she couldn’t spend the rest of her life having underwhelming sex now that she knew how good it could be.</p><p>To her, that meant she likely needed to break up with Luke. She didn’t see another solution. Then she saw the arousal in his eyes and what seemed like an erection growing in his pants as he walked by.</p><p>Emily decided to follow her instincts and see where they took her. She stood up and walked the same path through the apartment Luke had taken. She found him sitting at the end of their bed.</p><p>Emily’s heart pounded as she approached Luke. She felt like it was an enormous risk to try and see if he was genuinely aroused. If she was wrong, it could ruin whatever relationship was left between them. If she was right, perhaps the devastation she feared wouldn’t have to unfold.</p><p>Luke looked up as Emily stopped in front of him. She ran her fingers through his hair and smiled.</p><p>“He fucked me right here. In our bed,” she said.</p><p>Luke looked away but Emily took his head in her hands and gently guided his gaze back to her.</p><p>“Emily, please,” Luke said.</p><p>There was anguish in his eyes, but Emily saw the arousal too. She’d been with Luke for almost a year. She knew when he was turned on. She knew what desire looked like from him.</p><p>“I woke him up with a blowjob, right here, in our bed,” she continued. “It was Saturday morning. I crawled under the sheets and took his big cock into my mouth until he was hard as a rock. Then I put a condom on him and sat down on his dick.”</p><p>Emily felt a wild surge of lust as she recounted the details of her early morning encounter with Jameer. She was stunned at how much it aroused her to look into Luke’s eyes and tell him what she’d done with another man.</p><p>“I fucked him in our bed. I rode his big cock until I had a huge orgasm,” Emily said as she stared into Luke’s eyes.</p><p>She loved that he didn’t look away. He didn’t push her hands away from his head and storm out of the room. Instead, he stared up at her and let the arousal spread through his body. Emily saw it. She saw the fight go out of him. She saw the disappointment and heartbreak depart as desire took over.</p><p>She saw his erection, too. It was undeniable. He was hard as a rock. Emily could see the tent in his pants. She liked it. Loved it, even. Her boyfriend was stiff as he thought about her being with another man.</p><p>Emily leaned down and kissed Luke. He parted his lips and she gently probed his mouth with her tongue. He kissed her back. He moaned into her mouth.</p><p>She let her hands fall from his face and move between his legs. He didn’t fight it as she unzipped his pants and freed his cock. Her fingers wrapped around the erect flesh and Emily deftly stroked him.</p><p>Emily wondered if Luke could feel her arousal like she could feel his. Could he tell that she was overwhelmingly excited?</p><p>As lust flooded her body, Emily felt a deep desire to take Luke’s cock inside her. She knew it wouldn’t compare to what Jameer had to offer, but she wanted it anyway. She wanted him to fill her. She wanted him to flood her pussy with his cum.</p><p>She didn’t care to consider the reasons behind her desire. All she knew was that she wanted him. Emily released Luke’s cock and stepped back to strip. He watched her intently as she disrobed, exposing her slender, naked body to him.</p><p>Luke made no effort to resist her desires as Emily straddled him while he sat at the edge of the bed. She reached between their legs and guided his cock into her soaking wet pussy.</p><p>He groaned as Emily sat down on his erection, taking the entirety of it inside her. She moved her hips back and forth, grinding on her boyfriend’s stiff dick.</p><p>He’d welcomed her in his lap, but Emily wasn’t sure he was fully into fucking her. For a moment she wondered if she’d made a mistake, if this was going too far.</p><p>Then something seemed to change. It was like Luke’s arousal had been pressing up against an emotional dam and it finally broke through. He squeezed her ass tightly and wrapped his lips around her nipple to suck on it. He moved Emily on his cock. He fucked her as she sat in his lap.</p><p>“Fuck me, Luke,” Emily said as she pulled him against her chest and reveled in the lusty way he sucked on her nipples.</p><p>Luke groaned and squeezed her ass harder. He moved her back and forth over his cock at a rapid pace. Emily knew he was going to cum soon. She wondered if he was thinking about Jameer, and if the idea of another man fucking her is what was driving his lust.</p><p>“Emily…fuck, oh fuck,” Luke said. He was completely lost in his lust.</p><p>“Cum inside me, Luke,” Emily said. “Cum inside me.”</p><p>Luke groaned and climaxed as Emily pulled him close. She ran her fingers through his hair and down his back as he kissed her breasts.</p><p>“That was so good,” Emily said.</p><p>Luke lifted his head and looked at her. He smiled before Emily pulled his lips to hers for a long, slow kiss. She was heartened by Luke’s desire to feel their tongues mingling even after he’d had an orgasm.</p><p>When Emily lifted her pussy off of his shrinking cock, his cum spilled out. She watched it leak onto the floor before picking up her panties and using them to soak up the mess.</p><p>“I’m not entirely sure what you’re feeling, but we can talk more about this whenever you want,” Emily said before turning to the dresser and pulling out a fresh pair of panties. She turned back to Luke and continued, “Or you can kick me out, I suppose. I know it’s not okay to have slept with Jameer. I really do.”</p><p>Luke looked up at her without a hint of anger in his eyes. “Don’t leave,” he said. “You’re right that we need to talk, but I need time to figure out what this all means. I never expected to feel any kind of, well, desire, but it happened.” He leaned forward and ran his fingers through his hair. “How would you feel about getting dinner and just relaxing with a movie?”</p><p>“That would be great,” Emily said before kissing Luke again.</p><p>Instead of feeling dread and sadness, Emily felt hopeful. She felt like there was a chance she’d get to stay with Luke, whom she loved, and perhaps enjoy the kind of sex she’d discovered she needed.</p>
