They hopped on and just like that they were off towards the top of the mountain with their feet dangling and an icy breeze biting at the small patches of skin that weren’t covered by layers of warm fabric.</p><p>“I’m sure Adam will keep me safe,” Ruby said.</p><p>Christian glanced at his wife and saw a smile on her face. Had he not known about her extracurricular activities with Adam he would have taken that comment at face value. He did know, though, and that ensured that her comment carried extra meaning. Meaning that he found far more arousing than any man should have.</p><p>“I should have taken you skiing years ago,” Christian said.</p><p>“Why?” Ruby asked.</p><p>“It turns out that you look really cute in ski gear,” he replied.</p><p>Ruby laughed and leaned into him. She reached over and her hand drifted between his legs and for a moment Christian felt like he was a teenager again. He’d been on the receiving end of a handjob on the lift once and while he suspected his wife wasn’t going to take his cock out and jerk him off, her amorousness over the past handful of days made it seem like it was at least a possibility.</p><p>“You really think I look cute?” Ruby asked.</p><p>Christian turned to her and smiled. “Cute and sexy, in fact. I like that you went with the tight ski pants. They make your ass look incredible, if you don’t mind me saying.”</p><p>Ruby rubbed Christian’s cock through the thick ski pants he’d chosen and he felt it come to life. “I don’t mind at all, especially since that means you were staring at my ass. I like that my husband still enjoys staring at my ass.”</p><p>Christian suspected that Ruby liked that Adam would be staring at her ass, too. He couldn’t help but wonder just how much teaching would be going on and how much time they’d spend flirting or, if they could find a little privacy, fooling around.</p><p>“I do like staring at your ass,” Christian said.</p><p>“You know, you probably won’t be the only one to stare at my ass,” Ruby said.</p><p>Christian felt the almost instantaneous erection that formed between his legs. He wondered if his wife felt it too. More than that, he wondered if she’d mentioned other men staring at her ass on purpose. Was it possible she knew that he’d been watching? No, it couldn’t be possible. He’d been careful and Ruby had shown no sign that she new Christian had done a little bit of spying over the course of their Christmas.</p><p>“I guess you’re right,” Christian said. “Especially when an ass looks as good as yours does in those pants.”</p><p>Ruby smiled and rubbed him vigorously. He wasn’t quite getting a handjob, but it was awfully close. “That doesn’t bother you?” she asked.</p><p>Again Christian wondered if his wife had somehow discovered that he’d developed an interest in her enjoying another man. That man happened to be her brother-in-law, but Christian couldn’t deny that he found the whole thing far more arousing than he thought possible.</p><p>“I guess it doesn’t,” he answered.</p><p>“You’re awfully hard,” Ruby said.</p><p>“Well, my wife is playing with my cock on a ski lift,” Christian replied. “That’s not the sort of thing that happens every day.”</p><p>“I guess it isn’t,” Ruby said.</p><p>She seemed content to leave it at that, but Christian couldn’t help but wonder what his wife was thinking. He wished he could be inside her head for just a little to suss out what was going through her mind.</p><p>Ruby pulled her hand from between his legs as they neared the end of their journey. She gave Christian a quick kiss on the cheek and he turned so their lips met. Ruby’s tongue was in his mouth in the blink of an eye and it was far more active than Christian had expected. There was no question his wife was in a giving mood since they’d arrived in Vermont and Christian couldn’t help but enjoy it, even if it seemed to have been inspired by her affair.</p><p>“That was fun,” he said.</p><p>“Yes it was,” Ruby replied before gently wiping a bit of saliva from her lower lip. “Just the kind of fun I like.”</p><p>The smile she offered and the twinkle in her eye reminded Christian of how Ruby had been when they first met. Back then she had a seemingly boundless desire for sex and it felt like her dalliance with Adam had reignited some of that, which was in part why Christian still couldn’t bring himself to say anything. He wanted to enjoy his wife’s newfound lust and he wanted to ride the wave of unexpected lust it inspired in him, too.</p><p>“Be safe today,” Christian said as the lift flattened out and prepared to drop them off. “Don’t try to do too much. That’s how people get hurt.”</p><p>“I won’t, I promise,” Ruby said.</p><p>At the direction of the attendant they disembarked the lift as Marie and Adam approached with smiles on their faces.</p><p>“Hey you two!” Marie called out.</p><p>Christian and Ruby waved as they all met and exchanged hugs.</p><p>“So, brother, are you ready for a race?” Marie asked.</p><p>“You know I am,” Christian replied. “As long as you’re ready to lose.”</p><p>Adam laughed. “Look who’s feeling confident. How about you, Marie, are you feeling confident?”</p><p>“I certainly am,” Marie said. “In fact, I think we should make a bet. Whoever loses buys dinner tonight and it has to be a nice dinner. Drinks included.”</p><p>Christian looked at his wife and smiled. “What do you think? Is that worth the risk?”</p><p>“I believe in you,” Ruby said. “Make the bet.”</p><p>Christian turned to his sister and smiled. “Alright, you’ve got a bet.”</p><p>They shook on it and Marie said, “I’ll meet you at the start of the run, then. I don’t want to hear any whining when I beat you, though. Take your defeat like a man.”</p><p>Marie walked off and Christian turned to Adam. “You’re sure you’re okay giving lessons today? I’m sure we could find someone else to teach Ruby the basics so you can do some real skiing.”</p><p>“Not at all,” Adam said. “I like teaching. Honestly, I do. It takes me back to my youth. It’ll be fun. Plus, we’re here for a few more days so there should be plenty of time to ski.”</p><p>Again Christian wondered how much teaching would actually happen. Strange as it seemed, part of him hoped they were going to sneak off and find a way to fuck instead of doing any ski instruction. The only thing that frustrated him was that it didn’t seem possible to watch.</p><p>“Well, thank you,” Christian said. “I really appreciate it.”</p><p>“I do too,” Ruby replied. “It’s nice to have a good teacher.” She leaned into Adam and Christian felt his cock stir to life once more, which meant it was time to leave before he sprouted a full-on erection.</p><p>“Alright, I’ve got a race to attend,” Christian said. “You two have fun if I don’t see you again. Otherwise, we’ll meet at the bottom of the mountain later today.”</p><p>Christian turned and walked towards the top of the run where Marie was almost certainly raring to go. He looked back just once and saw that Adam had already begun his instruction. He was standing behind Ruby and showing her just how much she needed to bend her knees. That necessitated touching her, which Christian couldn’t help but find arousing. He looked away just as his cock surged to life once more. He couldn’t very well race his sister with a noticeable bulge in his pants.</p><p>“Are you ready to get your ass kicked?” Marie called out as Christian approached.</p><p>“Not at all,” Christian replied. “It’s a good thing I have no intention of losing. You know, I was thinking that surf and turf sounded exceptionally good for dinner. Maybe I’ll get a glass of barrel-aged Scotch along with it. What do you think?”</p><p>“Agreed. I hope your wallet can handle dropping $500 on dinner,” Marie shot back playfully.</p><p>They lined up next to each other, drove their poles into the packed snow, and after a brief countdown, took off down the mountain.</p><p>They’d both skied the mountain numerous times before and raced on almost all of those occasions, so they knew the most efficient route to take. That made for a competitive, neck and neck race. At one point Christian lost his balance and nearly toppled over, putting him a few ski lengths behind Marie. When she looked back to taunt him she nearly lost her balance, allowing him to catch up.</p><p>Ultimately, Marie pulled ahead at the end, crossing the unofficial finish line just a few ski lengths ahead of Christian. She pulled her helmet off and did a little dance on her skis to gloat and he tossed his helmet into the snow as a brief-but-genuine sense of annoyance surfaced.</p><p>“Well done,” Christian said after letting out his frustration. “It was a good race.”</p><p>“It was,” Marie replied. “And now we know that I’m the far superior skier, so that’s also a nice benefit.”</p><p>Christian laughed and picked up his helmet before they headed towards the lift. Soon enough they were on their way up the mountain once again.</p><p>“This is the part I like the most, you know,” Marie said. “The days after Christmas. Celebrating with mom and dad is never great, but I really do like hanging out afterwards, skiing, going into town, all that.”</p><p>“Does that mean you’ll come two years from now? It won’t be as much fun without you,” Christian replied as he watched the skiers below.</p><p>“I’m sure we will,” Marie said. “I almost always have a few moments where I feel like I never want to come back. Who knows, maybe I’ll be pregnant in two years and I’ll suddenly be the favorite.”</p><p>“Are you and Christian working on that? Because, honestly, that would be good for all of us. I feel like they need just one grandkid and they’ll be so much happier,” Christian replied.</p><p>“You know, I wasn’t sure about it, to be honest. Now, though, I think we might be,” Marie said.</p><p>Christian studied his sister’s face and saw just a hint of stress there. “What changed?”</p><p>Marie looked away for a moment before turning back to him. “This wasn’t a great year for us. There was a lot more fighting than usual. I might have suggested that Adam take a job at a private firm so we could make more money. That probably wasn’t fair of me. I don’t think he’d enjoy a job like that. One of the offers was four times what he makes now, though. I guess I got a little greedy. Things have felt different since we got here, though. Maybe it’s just a vacation thing, but usually coming to see mom and dad frustrates Adam, so I don’t think that’s what it is.”</p><p>“Different?” Christian asked.</p><p>“Yeah, different, though in the way that a brother probably doesn’t want to hear all that much about, if you know what I mean,” Marie replied.</p><p>Christian laughed. It seemed that fucking Ruby had inspired a great deal of lust in Adam as well. Marie probably would have been heartbroken if she knew what her husband was up to, but Christian wasn’t going to be the one to tell her, especially since it seemed like everyone might have been benefiting from it, at least to a certain degree.</p><p>“Is that Ruby?” Marie asked as she pointed at the gentle, snowy slope to the right of the lift.</p><p>Christian looked over and saw a woman in tight ski pants and a white jacket making her way down the gentle hill. She looked quite unsure on her skis, which made him quite certain it was Ruby.</p><p>“I think it is,” he said.</p><p>“She’s pretty hard to miss in those pants,” Marie said.</p><p>She looked towards her sister and asked, “Do they upset you?”</p><p>“Upset me? No. I wish I had the confidence to wear them. I mean, did you see her ass in them? It looks amazing,” Marie said.</p><p>Christian laughed. He couldn’t argue with her. Ruby’s ass looked incredible.</p><p>“I’m surprised it doesn’t bother you, though. She looks a little like one of those ski bunnies that hits the slopes looking to get laid,” Marie said.</p><p>“She’s a little older than most of those girls,” Christian replied. “I doubt the twenty year old ski instructors are eyeing my wife.”</p><p>Marie laughed. “I suppose you’re right.”</p><p>The lift dropped them off at the top of the mountain once more and Marie’s face lit up as she spotted a friend. “Will you be okay without me?” she asked. “I haven’t seen Sarah in years. I wanna go catch up.”</p><p>“Sure,” Christian said. “I’ll find you a little later.”</p><p>Marie walked towards her friend, leaving Christian on his own. He considered upping the challenge and taking one of the more difficult runs down the mountain, but he couldn’t quite shake his desire to watch Ruby and Adam, so Christian set off towards the bunny slope.</p><p>He found a spot a fair distance away so he could watch them. For the most part Adam was offering instruction like anyone else would. Every once in a while he would touch Ruby in a far more intimate way than a typical instructor. A few times his hand found its way to her ass for a quick caress and once Christian saw Adam full on squeeze Ruby’s bottom. Each time he looked around to make sure no one nearby was watching, though he didn’t seem to spot Christian spying from afar.</p><p>Ruby couldn’t seem to keep her hands off of Adam, but she too was doing a good job of making it seem professional. It appeared as though she was reaching out to grab him for balance, but Christian suspected it was more than that. He was certain he saw her brush her hand over Adam’s crotch at one point. Christian was a little too far away to judge it, but he guessed that if he was closer the whole thing would seem rather intimate.</p><p>Right as Christian was ready to walk away and take one of those challenging runs down the mountain he saw Adam take Ruby’s hand. They began a slow descent down the bunny slope, but instead of heading directly towards the bottom they veered left. Eventually they skied into the trees, disappearing from view.</p><p>Christian knew it was potentially unwise to try and follow, but it wasn’t his rational mind guiding his decision making in that moment. It was an incredible sense of lust that he had no control over. That lust demanded Christian get a closer look, so he took skied towards the trees.</p><p>Christian moved off the slope and into the trees a good distance north of where Adam and Ruby had disappeared, giving him plenty of space to make it less likely he’d get caught. The pine trees were particularly thick, which obscured his view somewhat, but when Christian saw two people engaged in what appeared to be a particularly passionate kiss he knew he’d found his wife and brother-in-law. Their skis were off and in the snow beside them, meaning they likely meant to stay for a little while.</p><p>Christian hid behind a tree and watched the two lovers indulge in their desire for each other. He was close enough to see Adam’s hands move to Ruby’s ass to grab it. He couldn’t hear anything, but it felt too risky to get any closer.</p><p>Ruby stepped back from Adam at one point and Christian figured the make out session was over, that they’d slipped away because they couldn’t bear being so close without being able to kiss each other and they’d satiated their desires. It turned out he was wrong, though. Instead, Ruby turned around, pulled her ski pants down to her knees, and bent over. She rested her hands on the thick trunk of a pine tree and looked back at Adam.</p><p>Christian suspected his wife had told Adam to fuck her, because a moment later his cock was out. Adam moved behind Ruby, slipped inside her, and just like that they were having sex. For the second time in a handful of days Christian was watching his wife and her brother-in-law fuck and once again he sported a painful erection. His only regret was that he wasn’t closer. He wished he could hear the sounds of sex they were no doubt making. He wished he could study the look on his wife’s face as she got fucked from behind in the woods. It felt so wild and dirty and insanely lusty and Christian had to work not to pull out his cock and masturbate as they fucked.</p><p>The sex was over after just a few minutes. Christian figured that the naughtiness of the situation likely heightened the pleasure, bringing them both to quick orgasms. The look on Ruby’s face was confirmation that she’d climaxed and he figured that Adam wouldn’t have pulled out unless he’d cum, which meant for the second time that week, someone else had cum in Ruby’s pussy.</p><p>Christian watched Ruby pull up her pants and turn around to kiss Adam. He moved behind the tree to try and hide as they moved towards the bunny slope once more. After giving them a solid ten minutes to make their way to the bottom of the slope – and to give his erection time to deflate – Christian made his way out of the woods and towards the bottom of the mountain.</p><p>“Christian!” Ruby called out as he reached the lift area.</p><p>He spun around to see his wife approaching with a smile on her face. “Hey,” Christian said. “How are the lessons going?”</p><p>“Spectacularly well,” Ruby said. “Adam’s an even better teacher than I thought.”</p><p>Ruby threw her body into Christian’s arms and they kissed. Her tongue was forceful and he parted his lips to welcome it into his mouth. His erection came back with a vengeance.</p><p>“What do you say we ride the chair lift together?” Ruby asked with a naughty smile on her face.</p><p>She took Christian’s hand and led him towards the lift without waiting for an answer. They hopped on and Ruby leaned over and kissed him again the moment they were on their way up the mountain.</p><p>Christian’s cock ached with desire. The knowledge that his wife had someone else’s cum inside her made kissing her so much hotter. The erection he sported felt like it would never fade. He wanted to pursue his arousal instead of trying to tamp it down. He reached over and pressed his fingers between Ruby’s legs. He rubbed her pussy through her skintight ski pants and she moaned into his mouth.</p><p>“Does that feel good?” Christian whispered.</p><p>“Yes,” Ruby replied.</p><p>Christian’s heart pounded as he moved his fingers northwards. Ruby moaned as he pushed them under the tight waistband of her pants and into her panties. He rubbed her soaking wet pussy and she pushed her tongue deep into his mouth. Christian knew his fingers were bathed in another man’s cum and it turned him on. When Ruby reached over and played with his cock through his ski pants Christian thought he might cum instantly. The pleasure was so intense it seemed unreal.</p><p>“Did you enjoy watching?” she asked.</p><p>“What?” Christian replied. It was the only word his brain could produce.</p><p>“Did you enjoy watching Adam fuck me?” Ruby asked.</p><p>Christian responded with a moan as the pleasure of being stroked through his ski pants intensified.</p><p>“That was you, wasn’t it? Just like it was you on Christmas?” Ruby asked. “Just like it was you outside the woodshed?”</p><p>Christian nodded and Ruby kissed him again. He’d never felt such passion emanating from his wife and the sensations of lust pulsing from between his legs bordered on overwhelming as the realization that she knew about his voyeuristic activities set in.</p><p>“Yes, it was me,” Christian said.</p><p>Ruby stroked him faster and Christian knew an orgasm was inevitable if she continued. There was no need for her to pull out his cock. He was so turned on he was going to unload in his pants.</p><p>“He came inside me,” she said as Christian played with her clit.</p><p>“I know,” Christian replied.</p><p>“It turns you on, doesn’t it?” she asked.</p><p>Christian nodded and Ruby kissed him again. It was a desperate, wild, feverish kiss and when she sucked hard on his tongue all Christian could do was moan.</p><p>“Ruby…fuck…” he said as his orgasm became inevitable. There was no stopping it. “Ruby…oh, fuck…Ruby…I’m cumming.”</p><p>Christian climaxed in his pants on the ski lift. His body trembled from head to toe as the most pleasurable orgasm he’d ever experienced exploded from between his legs. He closed his eyes and leaned back as Ruby continued to gently play with his cock, ensuring every drop of semen spilled into his pants, making a hot, sticky mess.</p><p>“Finish me,” Ruby said. “Before we reach the top. Please, finish me.”</p><p>Christian turned his attention to his wife and they kissed as his fingers danced over her clit once more. In short order he felt her thighs trembling fiercely. She grabbed his wrist and held it tight, urging him to keep his hand between her legs as she climaxed. Christian felt more of Adam’s cum ooze from her pussy as she enjoyed an orgasm while moaning into his mouth.</p><p>“Thank you,” Ruby whispered.</p><p>“Thank you too,” Christian said as he pulled his hand from her pants.</p><p>He studied the slippery coating on his finger and looked for somewhere to rub it off. Ruby smiled, took Christian’s hand in hers and wrapped her lips around his finger. She sucked Adam’s cum off of it and said, “It isn’t the first time I’ve tasted his cum.”</p><p>Another shudder of pleasure ripped through Christian’s body. He knew she’d swallowed for Adam, but it was astoundingly hot to hear her admit it.</p><p>“I know,” he said.</p><p>“You don’t mind?” she asked.</p><p>“Clearly I don’t, which is weird. I don’t care, though. I’m having too much fun to care.”</p><p>Ruby smiled. “I feel like the fun is just getting started.”</p><p>Christian returned her smile. He hoped his wife was right. He wanted more of what he’d just experienced. Pleasure like that was a rare treat and he was going to do whatever it took to enjoy more of it.</p>
