"Good morning," Marie said as Christian ambled into the kitchen in search of coffee.

He didn't expect to see his sister sitting there - it wasn't even 6 a.m. so he figured he'd be the first awake - so he was a little slow to respond. "Uh, hey, yeah, good morning."

Marie laughed. "I already brewed the coffee. You'll be out of your haze in no time."

Christian smiled at his sister, poured a cup, and said, "How about we sit outside?" Marie happily joined him, though it wasn't until they'd sat down that Christian wondered which of the chairs his wife and Marie's husband had fucked in the day before. He couldn't help but hope it was the chair he was seated in and he felt a small thrill at the idea that Ruby had taken Adam's cock for a ride in the very spot where he now rested.

"So, you and Ruby seemed to have fun yesterday," Marie noted.

Christian looked towards his sister and saw a knowing smile on her face. He was certain she'd heard them having sex - Christian had been quite loud - though he still didn't feel even the slightest bit embarrassed about it. "We did," he answered with a knowing smile of his own. "I hope it wasn't too distracting."

"No, not at all," Marie replied. "That's what couples do on vacation, right?"

The look on her face made Christian fairly certain that Marie and Adam had enjoyed a thoroughly pleasurable fuck too. Perhaps Adam was a lot like Ruby in that he couldn't help but feel desire for his wife after fucking another woman. That wasn't a conversation Christian was going to have with his sister - who he assumed didn't know about the affair between Adam and Ruby - but he liked that Adam wasn't expending all his sexual energy with Ruby.

"That is what couples do on their vacation," Christian said before slowly sipping his coffee and savoring the rich taste.

"Was it as good as it sounded?" Marie asked.

Christian was a little surprised at the forward nature of his sister's question, but their relationship had always been fairly open, even if they didn't see each other all that often. "It was," Christian answered. "How about for you? Did the first day of vacation prove to be everything you'd hoped it would be?"

Marie looked out at the lake, smiled, and said, "It did. It really did." She paused for a moment and added, "That's not the only reason I'm glad we came, though. It's really good to see you again, Christian. I know we haven't always been good about seeing each other, but I hope we keep making an effort to do it more often."

Christian couldn't help but smile, in no small part because he knew he had an entirely different motive for wanting to see his sister and brother-in-law more often. He liked seeing Marie, but he was more than willing to admit that the pleasure that came from knowing that his wife was fucking another man was a far more enticing reason. "I see no reason we can't see each other more often," he said. "I mean, I'd be more than happy to do something like this a few times a year and I'm sure Ruby would be on board too."

"Good," Marie said with a particularly happy smile. "So, what did you have in mind today?"

"Canoeing," Christian replied. "The rental comes with two canoes, life jackets, paddles, all the equipment we need, and the lake has a whole bunch of little islands we can visit, so I figured we'd all head out on a canoe trip. Maybe we pack lunches and meet up on one of those islands."

"That sounds perfectly idyllic," Marie said.

Christian laughed. "I know, right? Assuming our better halves are on board, I say we head out after breakfast, work up a good hunger with all that paddling, and then meet up for lunch."

Marie leaned over, clinked her coffee mug against his with a big smile on her face, and said, "That sounds perfect."

Marie and Christian had ended up in the same canoe at the start of their journey, which meant Adam and Ruby were together and roaming the lake all on their own. Christian tried his best to pay attention to the conversation with his sister, but his mind couldn't help but drift to what his wife and brother-in-law were doing. Was Ruby sucking Adam's cock in the canoe? Was she that bold? Were they fucking in the canoe? Had their found their way to a particularly private island to indulge in a quickie?

By the time they all convened on the island they'd picked out on the map - an island that happened to have a lovely beach they laid their picnic out on - Christian was overwhelmed with desire as he'd spent the better part of two hours thinking about his wife fucking another man.

That desire only deepened over the course of the two hours they all spent together on the island, mostly because Christian couldn't find a moment alone with Ruby to find out if she and Adam had been bold enough to find somewhere to fuck. He couldn't stop thinking about it and every time Ruby touched him and offered a flirty smile, Christian was absolutely certain she'd fucked their brother-in-law, that his cum was leaking out of her as they all sat there on the beach eating bread and cheese. He wasn't sure if it was true, but the idea of it was astoundingly hot.

Much to Christian's relief, Adam and Marie climbed in the same canoe for the trip back to the rental house. Christian and Ruby waved goodbye before turning to the beach to clean up the blanket and dishes from their picnic, but the moment the other canoe was out of sight Christian dropped the blanket and rushed towards his wife.

"Did you fuck him?" he asked after taking Ruby into his arms.

She looked up at him, smiled, and offered a long, sensual kiss. Her tongue tasted of cheese and a hint of wine - they'd brought a bottle of red - but Christian couldn't help but wonder if Ruby had sucked their brother-in-law's cock before they'd all enjoyed lunch on the beach. Had the tongue in his mouth pleasured another man's cock not that long ago? Had the lips pressed against his been wrapped around Adam's cock?

"Do you think I fucked him?" she asked. "Or do you just hope I fucked him?"

"I definitely hope you fucked him," Christian replied. "And I think you fucked him. I think you had plenty of time and there are plenty of little islands on this lake where you could have found a private space."

Ruby offered a flirty, naughty-looking smile and then slipped a hand down the front of Christian's swimsuit. She found his cock and stroked him slowly as she bit her lower lip and then said, "We did stop at a lovely little island. It was tiny, really, but there was enough space to have fun."

Christian moaned and asked, "What kind of fun did you have?"

Ruby stood on her toes, kissed his neck, and said, "Why don't I take you there so I can show you what sort of fun I had with Adam?"

She pulled her hand from his pants, smiled, and turned to continue picking up the remains of their picnic. Christian helped, this time with great speed, for he desperately wanted to get to that island and to release the arousal that had been building for the better part of four hours.

They loaded everything into the waterproof bag they'd brought, placed it in the canoe, and shoved off the beach. Ruby sat in the back and directed the canoe while Christian paddled furiously, almost as if his boner was leading the way and he had no choice but to follow it. Each time they approached a small island he got excited, and each time Ruby directed them right past it. The waiting didn't diminish Christian's lust, though. It only seemed to enhance it, for he couldn't stop thinking of his wife and their brother-in-law having intensely passionate sex.

Finally, Ruby directed them onto the beach of a tiny island, just as she'd described it. Christian pulled the canoe far enough up the sand that it wouldn't float away and turned towards his wife to see her take off the cover up she'd worn for most of the day. She reached up to untie her bikini a moment later and then pressed her body against Christian's.

"This is where I kissed him," she said softly before her lips found his. It wasn't a soft, seductive kiss like before. It was wild and passionate and eager. Her lips pressed hard against his and her tongue moved eagerly in his mouth. "This is also where I got on my knees for him."

"Wait, right here?" Christian asked. "Did anyone see you?"

Ruby smiled and fell to her knees in front of him. She untied his swimsuit and pulled it down to his ankles. "I don't care. I needed him in my mouth, Christian. I needed to suck his cock, to make him feel good like he makes me feel good."

A moment later her mouth engulfed Christian's cock. It felt heavenly and he couldn't help but moan as his mind went blank. All he felt was the pleasure of his wife's mouth around his exceedingly stiff dick. Ruby's tongue swirled around the underside of the head and then she swallowed nearly the full length of his shaft before slowly pulling back.

"Do you like that I sucked his dick on this beach?" she asked.

"Yes, fuck, yes, Ruby, I love that," Christian replied.

Ruby flashed a naughty smile and wrapped her fingers around his spit-soaked dick. She stroked him slowly, stopping to tease the head with her fingers at the end of each stroke. "You don't mind that I couldn't help but suck my brother-in-law's cock? You don't mind that I was so horny for him that I got on my knees on this beach and gave him a blowjob?"

"I love that you did that," Christian said. "I love that you couldn't help it, that you wanted him so badly."

Ruby swallowed his cock once more, this time bobbing up and down on the shaft for a few minutes as Christian watched while he imagined her doing the same thing for Adam. He'd seen her give him a blowjob before and he couldn't help but picture it. He saw the passionate way she blew their brother-in-law, the way her lips and tongue worked his shaft, the way she offered him such eager pleasure.

Ruby then stood and kissed him as she stroked his cock. She moaned into his mouth and Christian did the same. He was desperate to be inside her and he only hoped she'd be willing to offer him that pleasure.

"After I sucked his cock," she said softly. "He went down on me." Christian moved to fall to his knees, but Ruby stopped him. "He's still inside me. I'm sure you don't want to taste that."

Christian hadn't thought about that, but of course Adam’s cum was still inside her. He was surprised to find the idea of tasting it didn't horrify him, though. In fact, it was quite the opposite. There was something a little bit exciting about it, but he chose not to share that with his wife, for he thought she might find it a little weird.

"Can I fuck you?" he asked.

"I thought you'd never ask," Ruby replied. She took his hand and led him into the small stand of trees that occupied the middle of the exceedingly small island, which was really just a rocky outcropping with a little bit of dirt in which the trees had taken hold.

Christian saw a spot where the leaves had been kicked away and the dirt was clearly disturbed. It was the spot where Ruby and Adam had fucked. It had to have been.

"Is this...is this where he fucked you?" he asked.

Ruby let go of Christian's hand, lowered her bikini bottoms, and then turned and rested her hands against one of the trees. She stuck her ass out, looked over her shoulder, and said, "We started here. He took me from behind up against this tree. My pussy was soaked for him, baby. I was so wet it was dripping down my leg by that point. I was so wet his big cock slipped inside me without any resistance. My pussy was so desperate for him, baby. I needed him so badly."

Christian stepped behind her and slipped his cock into Ruby's pussy. He leaned forward until their bodies were pressed together and she looked back at him so they could kiss. Her pussy felt wondrous in every way. It was hot and wet and it felt just tight enough to provide that beautiful friction he craved.

"Fuck me, Christian," she said.

Christian fucked his wife and his imagination took over and transported him to the same island, just a few hours earlier. He saw Ruby standing naked against the tree with her hands pressed into the bark. He saw Adam standing behind her with his hands on her hips and his cock pumping in and out of her slippery pussy. He'd seen them fuck doggystyle before - up against a tree, in fact - and he easily transported that memory onto the island, filling his head with beautifully erotic imagery of his wife giving herself to their brother-in-law because she just couldn't help herself.

"Does my pussy feel good?" Ruby asked as she pushed back to meet his thrusts. "Do you like fucking my sloppy wet pussy?"

"Yes, I love fucking you after he's had you, Ruby," Christian admitted. "I fucking love it. Your pussy has never felt better than after he cums inside you."

Ruby looked over her shoulder and smiled at him. Christian found the energy to fuck her harder and she closed her eyes and let out a long, low moan. "I want you to cum inside me," she said. "I want you to flood my pussy with cum just like he did. Cum inside me."

"Is this where he came inside you?" Christian asked.

"No, I was on my hands and knees on the ground," Ruby said.

Something about it struck Christian as overwhelmingly hot. He wasn't sure why, but he loved that his wife was willing - perhaps even eager - to get on her hands and knees in the dirt so their brother-in-law could fuck her pussy and cum inside.

"I came too," she said. "I barely had to touch my clit and I came so fucking hard while he was pumping his load inside me. Is that how you want me, baby? Do you want me on my hands and knees on the ground?"

Christian pulled out, but that's not how he wanted his wife. Instead, he spun her around, lifted one of her legs, and slipped his cock inside her as she leaned against the tree. They kissed and their tongues engaged in a beautiful dance as he fucked her. He could feel his pelvis pounding hers with every thrust and he knew he was stimulating her clit. The way she moaned into his mouth meant she was going to cum, too. He knew it. He could feel it.

"Baby, I'm close," she said. "Please, cum inside me."

With one hand under her knee to hold her leg up and the other grasping her breast, Christian buried his cock in Ruby's pussy and came. His legs trembled from the pleasure of releasing his pent-up desire and she joined him in unleashing joyful, orgasmic moans, signaling that her pleasure was just as significant as his.

Both their chests heaved as he remained inside her for a few moments longer before pulling out and gently letting her leg down until she stood on two feet. Cum dripped from her pussy onto the dirt at the bottom of the tree and Ruby wore a smile on her face that looked as bright as Christian's felt.

"That was...that was indescribably hot," Christian said. "Holy fuck."

"I know. What a day I've had. I'm a very lucky girl," Ruby replied.

Christian felt like he was the lucky one, in no small part because their vacation was just starting
