Is that something you can do?”</p><p>“She bought a new TV?” Carson asked. “What for?”</p><p>“Well, the one in the guest house wasn’t very big,” Lauren said. “We didn’t really decorate that space thinking we’d have a long term guest.”</p><p>“Yeah, I guess that’s true,” Carson replied. “Does she need me now?”</p><p>Lauren nodded.</p><p>“Okay. Let her know I’m grabbing my tools and I’ll be right there,” Carson said.</p><p>Lauren popped out of her chair and surprised Carson with a tight hug and a kiss. “You’re a wonderful husband,” she said. “Thank you for letting my sister stay with us, and thank you for helping her through a tough time.” She kissed him again, this time with an extra touch of passion that brought Carson’s loins to life. “And thank you for last night. You were incredible.”</p><p>“It was my pleasure, believe me,” he replied.</p><p>Lauren grabbed his ass, smiled, and said, “I’d say all that working out you’ve been doing has really paid off. Maybe we can find the time to have a little more fun tonight.” They kissed again before Lauren let him go and gave him a swift smack on the ass as Carson turned and headed towards garage.</p><p>He grabbed his tool box and headed towards the guest house. Sophie greeted him at the door in a cropped t-shirt that showed off her taut stomach and belly button and a pair of exceptionally short shorts. She looked really good and the fact that her nipples were hard – she had the air conditioning cranked up – made it difficult not to stare for just a moment, an act that filled Carson with a sense of guilt.</p><p>“So, you bought a new TV?” Carson asked as he stepped inside.</p><p>Sophie closed and locked the door before spinning around with a smile on her face. “I did. I know there was already a TV here, but I got used to having a big screen back in New York and I figured I’d treat myself. Plus, TVs are really cheap these days. I promise, I’ll leave it when I move out. So, really, I bought you and Lauren a TV,” she explained.</p><p>Carson put his tool box down, did his very best not to stare at his sister-in-law’s nipples, and said, “Alright, let’s get this thing mounted.”</p><p>“The TV’s still in the box,” Sophie said. “Sorry about that, but it’s really big. I need your help getting it out.”</p><p>Carson smiled. “No problem.” He grabbed a screwdriver from the toolbox and used it to slice through the tape. “Alright, you hold the box and I’ll pull the TV out.”</p><p>Sophie did her part and soon enough the TV was resting face down on the couch as Carson opened the mounting kit.</p><p>“So,” Sophie began, “Lauren spoke glowingly about your performance last night.”</p><p>Carson separated the screws and set them on the coffee table as he looked up at Sophie. “I guess I shouldn’t be surprised. She tells you everything, after all.”</p><p>Sophie smiled. “She does. There are some things she can’t tell me, though.”</p><p>Carson perused the instructions on the mounting kit and said, “Yeah? Like what?”</p><p>Sophie sat on the oversized arm chair, crossed her legs, and asked, “When she kissed you, did you think about Miguel? Did you think that her lips had been wrapped around his cock less than an hour before she kissed you? Did you think that his cum had been in her mouth as she offered you her tongue?”</p><p>Carson wasn’t sure what motivated his sister-in-law’s questions, but she was right on the money. The first thing he’d thought when Lauren kissed him was that her lips had been around another man’s cock that night. When her tongue pushed into his mouth, all he could think was that she’d taken another man’s cum in her mouth that night. He hadn’t tasted anything unusual, but that didn’t stop Carson from thinking about it.</p><p>“Yes, I thought about those things,” he admitted.</p><p>“Did it turn you on?” Sophie asked. “Did thinking about your wife sucking another man’s cock turn you on?”</p><p>It was a little embarrassing, but Carson nodded.</p><p>Sophie leaned forward, smiled, and asked, “Are you turned on right now, Carson?”</p><p>He looked up to catch a glimpse of her splendid cleavage before staring into Sophie’s eyes and nodding. It seemed utterly pointless to try and argue with her. Her question might as well have been rhetorical. She knew the answer.</p><p>“You can’t help it, can you?” Sophie asked. “All you have to do is think about your wife being on her knees in front of Miguel and you get turned on, don’t you?”</p><p>Carson gripped the hard metal of the mounting kit and tried not to let his mind wander to that exact image. He couldn’t help it, though. It popped into his head. He saw Lauren on her knees in front of Miguel. He saw her giving a blowjob. He saw her giving a passionate blowjob to a man that had made her cum in an exquisite fashion, as Lauren had confessed to her sister.</p><p>“Well, I suppose we should get this TV mounted, shouldn’t we?” Sophie said.</p><p>Carson was thankful for the sudden turn away from her line of questioning. Despite knowing it was deeply unwise to let Sophie turn him on like that, Carson couldn’t resist.</p><p>“Right, absolutely,” he said. Carson hopped to his feet and set about screwing the mount into the wall. He took great care to ensure it was even – he couldn’t very well install a crooked TV – and thanks to the straightforward nature of the instructions it wasn’t long before half the job was finished.</p><p>“Look at that,” Sophie said as she stepped behind Carson and gently pressed her body against his. Her hands found his waist and she leaned closer as if she was carefully studying his work. “I’m actually impressed. I kind of figured handiwork might be a little out of your area of expertise.”</p><p>Carson readied a snarky reply, but Sophie’s hands moved past his waist and a few inches down his thighs and his mind went blank. She pressed her breasts into his back and for a moment Carson forgot himself and enjoyed the sensation of a beautiful girl seemingly flirting with him. He found his sanity a moment later and spun out of Sophie’s grasp.</p><p>“Now we just need to mount the arm to the TV and you’ll be all set,” he said.</p><p>Sophie made a pouty face and put her hands on her hips, but Carson chose to ignore her. He remained utterly confused by his sister-in-law. At times it seemed like she genuinely had Lauren’s best interests at heart – her approach to Lauren’s happiness was unusual, but it seemed to be working – and at times it seemed like she was intent on destroying Carson’s marriage. Sometimes he wondered if she simply enjoyed sewing the seeds of chaos and seeing how it all played out.</p><p>“Did it make you uncomfortable when I touched you, Carson?” Sophie asked.</p><p>Carson fumbled with the screws for the arm and dropped them on the floor. He dropped to his knees to search for them and said, “It doesn’t feel right. You touching me like that, I mean. It feels…I don’t know, it just feels like Lauren wouldn’t like it.”</p><p>“Are you sure it doesn’t feel right, Carson?” Sophie asked.</p><p>Carson found the screws he’d dropped, got to his feet, and grabbed the arm to secure it to the back of the TV. “Sophie, please,” he said.</p><p>Sophie let out a gleeful laugh and dropped onto the oversized arm chair once more. He looked over to see an equally gleeful smile on her face and felt that same sense of confusion. Was his sister-in-law just fucking with him? Was she trying to drive him insane? Or, was it possible that she knew him better than he knew himself and she’d actually offered him and Lauren the key to a long, happy marriage and a thriving sex life? Carson couldn’t tell. His mind was a confused mess, largely thanks to exceptional levels of arousal that he’d experienced since Sophie took up residence in their guest house.</p><p>“Do you want Lauren to fuck Miguel?” Sophie asked.</p><p>Carson wanted to finish mounting the TV and leave before Sophie could lure him deeper into her web, but with one simple question she made it damn near impossible for him to do so.</p><p>“I don’t know,” he answered. “And that’s the truth. I really don’t know. I mean, what sort of man wants his wife to fuck someone else?”</p><p>“What sort of man loves kissing his wife after she’s sucked someone else’s cock?” Sophie asked. “You, Carson. You’re that sort of man. We both know you loved welcoming Lauren home after she’d sucked Miguel’s cock and swallowed his cum. We both know you were more turned on than you’ve ever been as you fucked her. We both know your orgasm rivaled the best you’ve ever had.”</p><p>Carson sat on the couch and rested his arm on Sophie’s new TV. Every word she’d spoken was true. He and Lauren had enjoyed great sex the night before and there was no question it was fueled by the fact that she’d just given a blowjob to another man. It wasn’t just Carson’s end of it that was fueled by that, either. Being with Miguel clearly left Lauren in an intensely aroused state and, for whatever reason, left her as eager to fuck Carson as she’d ever been.</p><p>Sophie stood up and sauntered towards Carson. She squeezed into the spot next to him on the couch and put her hand on his knee. Carson watched her fingers move in small circles over his skin and moved to get up.</p><p>“Don’t move,” Sophie said. “Stay right where you are and tell me if you want Lauren to fuck Miguel. Because she will, Carson. She will if I tell her it’s okay. She’ll fuck Miguel. She’ll enjoy it, too. She’ll have the kind of sex she truly craves. She’ll have the kind of sex she’s been telling herself she doesn’t actually want. She’s convinced herself that you’re the best she can do, Carson, but we both know that’s not true. We know Lauren deserves better. That’s why you’re working out. That’s why you’re giving her more attention. She still deserves what Miguel can give her, though. Don’t you want her to have that?”</p><p>Carson nodded and Sophie’s hand moved under his shorts and up his leg. His pulse raced as she neared his crotch before stopping her progress. Her fingers continued to move in small, slow circles as she said, “I need you to say it, Carson. Tell me that you want your wife to fuck Miguel.”</p><p>“I…I want Lauren to fuck Miguel,” Carson said.</p><p>“Tell me that your wife deserves to fuck him,” Sophie said.</p><p>“Lauren…she…Lauren deserves to fuck Miguel. She does,” Carson replied.</p><p>Sophie pulled her hand from his shorts and Carson felt an odd mixture of relief and disappointment. He knew it was utterly insane to want his sister-in-law to touch his cock, and yet the idea of it was wildly arousing.</p><p>“You’re a good husband, Carson,” Sophie said. “I hope you know that.”</p><p>“Oh, well, thank you for saying that,” he replied.</p><p>Sophie smiled and took his hand in hers. Her skin was soft and warm and when she gently pulled Carson’s hand and laid it against her exposed, taut stomach he offered no resistance.</p><p>“I’m not wearing a bra,” Sophie said. She applied gentle pressure and his fingers moved over her belly button and under the bottom of her cropped t-shirt. “A good husband like you deserves a reward for being willing to sacrifice for his wife. I’m willing to give you a reward, Carson.”</p><p>Carson wasn’t exactly sure what Sophie was offering, but she seemed to be asking him to touch her breasts. He couldn’t help but stare at them. They looked so beautiful in the tight t-shirt. Her nipples were rock hard. She seemed excited, perhaps at the prospect of being touched. Carson let his fingers wander a few inches closer to her breasts and Sophie offered a quiet moan.</p><p>“Go ahead,” Sophie said. “Claim your reward.”</p><p>Carson almost did it. He almost played with his sister-in-law’s breasts like she seemed to want him to. He couldn’t, though. It felt wrong. It felt like cheating, and despite the fact that Lauren was cheating on him, it felt wrong.</p><p>“No, I can’t,” Carson said as he stood up. “I’m sorry, I can’t.”</p><p>Sophie stared at the bulge in his shorts and said, “It seems like you want to.”</p><p>“Sophie, please, I’m sorry for that, but let’s just mount the TV and I’ll leave. Okay?” Carson said.</p><p>Sophie stood, smiled, and stepped closer. “Okay. Let’s mount the TV.”</p><p>They lifted the TV off the couch, carefully placed it on the mount, and with a little finesse managed to finish the job.</p><p>“It looks good,” Sophie said as she stepped back to admire her new TV. “Thanks for your help.”</p><p>“It was my pleasure,” Carson replied.</p><p>Sophie glanced at his still semi-erect cock, smiled, and said, “I know.”</p><p>Carson looked away. He was embarrassed by his inability to control his desire.</p><p>“It won’t be long before Lauren wants to see Miguel again. It will probably take a few weeks to convince her to fuck him, but I suspect it won’t be long before she has his cock in her mouth again. Your wife can be insatiable when she’s inspired,” Sophie explained. “I bet you can be too, though, so why don’t you get over there and give her a little more of what you gave her last night.”</p><p>Again Carson’s mind was awash in thoughts of his wife blowing another man. Again he pictured Lauren on her knees in front of Miguel. His arousal deepened. “Good idea,” he said.</p><p>Carson packed up his tool box, waved goodbye to Sophie, and headed across the yard and into the garage. He was going to do as Sophie suggested. He was going to fuck his wife again and he was absolutely going to think about her being with Miguel as he fucked her. There was no avoiding it. Sophie had made sure of that.</p>
