The Summer Rental - Part 9

Click here to read the previous parts of the story.

Christian woke to an empty bed and memories of the day before - memories of wild, boundary-pushing sex - filled his head and put a smile on his face.

A moan - a distinctly sexual moan - caught Christian's attention and he sat up. He thought of how he and his sister had cleaned Adam's creampie from his wife's pussy. His balls tingled with excitement at having done something so astoundingly dirty, and yet he didn't feel the slightest bit of shame. It was pure pleasure he felt and that he'd experienced the day before.

Though he wanted to investigate the source of the moan, Christian needed to pee, so he headed for the bathroom and emptied his bladder. As he did so, his eye caught the sight of something unusual in the trash. When he'd finished and flushed, Christian bent over and plucked a small round packet from the bin.

"What?" he said to himself as he examined what was unquestionably Ruby's birth control pills. She wasn't even half-finished with them, so there was no good reason for the pills to have ended up in the trash.

For a handful of seconds Christian stood there with his dick hanging out and a fog of confusion slowly rolling over his brain. Of course, the reason for the pills ending up in the trash was obvious, and when it dawned on Christian that his wife was taking the risk of getting pregnant with her brother-in-law's baby he was hit with a tidal wave of lust.

Christian was caught off guard by his body's reaction to a piece of news that would have destroyed most men. Unless he was wrong, Ruby had decided she wanted to have her brother-in-law's baby, and in doing so she'd also quite clearly decided she wasn't anywhere near as keen on having Christian's baby.

That should have left him simmering in a pool of anger. It should have filled him with a kind of hurt that most people couldn't recover from. Instead, Christian felt himself sinking deeper into an astonishing level of arousal. It wasn't the sort of animalistic desire that left him with a raging erection and a need to fuck, though. Instead, it was the sort of arousal that made it feel as though every cell in his body had come alive and was focused entirely on the erotic news he'd just received.

Christian tossed the birth control pills into the trash, tucked his cock back into his underwear, and left the bathroom. A moan reached his ears as he neared the bedroom door. It sounded like Ruby, or Christian was so desperately hoping it was his wife getting fucked - and already well on the way to taking her brother-in-law's seed in her unprotected pussy - that he assumed it was Ruby.

Christian's hand trembled a little as he reached for the door handle. It wasn't nerves, though. It was excitement. He was turned on. He wanted to step out into the hallway and indulge in the pleasure of his wife's desire to have another man - to have her brother-in-law - get her pregnant.

As he stepped into the hallway, the distinct sounds of sex melded with the beautiful moans and Christian closed his eyes and stood still as he listened. He heard the sound of flesh meeting flesh and he imagined Adam between Ruby's legs, fucking her in missionary. He heard the quiet groans of the bed frame as it strained from the rigorous sex it was playing host to. He was fairly certain he heard the occasional sound of kissing, too.

Christian opened his eyes and stepped towards the door to his sister and brother-in-law's room. The symphony of pleasure got louder with every step, and though he'd made that particular journey before, it felt far more exciting to do it with the knowledge that his wife was having truly unprotected sex with her brother-in-law.

As he stepped into the doorway, Christian saw his brother-in-law's cock moving in and out of Ruby's pussy. She was on her back with her legs spread wide and she was taking slow, deep thrusts into her body.

Marie was lying next to Ruby and they shared the occasional kiss along with a bit of sensual touching as Adam had his way with his sister-in-law.

"What do you want?" Adam asked.

Christian figured it was Ruby that was going to answer, but the question wasn't directed at her. "I want you to get her pregnant," Marie replied. "I want you to give her a baby, Adam."

Christian watched his sister spread her legs and reach between them to play with her pussy. She rubbed her clit a little and let out a wild moan before plunging three fingers between her labia and deep into the wetness within.

"What do you want?" Marie asked her husband.

"I want to get you both pregnant," Adam replied. "But I want her to be the first to carry my seed. After all, her pussy feels better than yours and she makes me cum harder, so she deserves to be the first to get pregnant."

Christian watched his sister's face as she experienced the same kind of bliss he enjoyed every time Ruby told him that his brother-in-law fucked her better. This was taking things to a different level, though. It was so much more primal, and the arousal that came with it carried greater potency.

When he couldn't stand to wait in the doorway any longer, Christian stepped into the room. Marie saw him first and she sat up and smiled before Adam looked over his shoulder and took note of his brother-in-law's presence. By that point, Christian's cock was hard, making it perfectly clear to everyone that he had no intention of objecting to Ruby's decision.

"Hey, baby," Ruby said as Adam sat up with his cock still buried in her pussy.

"Hey," Christian replied as Marie leaned over, took one of Ruby's nipples in her mouth, and sucked gently, eliciting a moan while she continued to slowly masturbate. "I found your pills...in the trash."

Ruby smiled and gently ran her fingers through Marie's hair before pulling her a little closer. "I was hoping you would. How did it feel when you realized when I'd thrown them away?"

"Exciting," Christian answered.

Ruby looked at Adam, smiled, and said, "See. They're the same. I couldn't say why, but they both crave our pleasure more than they crave their own. They crave our happiness, our satisfaction, over their own. They find a kind of pleasure in it that I'm fairly certain we can't begin to understand."

Adam held Ruby's gaze as he reached back, slipped two fingers into his wife's pussy, and said, "You're right. Of course you're right. I shouldn't really be surprised."

Ruby smiled. "We can have what we want, Adam. You can get me pregnant. You can put a baby inside me. You can start our family and yours. You can give me what I crave, what I've actually craved for years but have been too afraid to give voice to."

Adam leaned down to kiss her and began to thrust once more. Christian stopped at the foot of the bed and sank to his knees for an even better view of his brother-in-law's cock filling his wife's pussy with slow, deep thrusts. It was a romantic kind of sex. It was lovemaking, not fucking. They were clearly taking a more gentle approach for their first attempt at getting Ruby pregnant and Christian couldn't help but find it immensely arousing.

"Adam...I want to watch them worship you," Ruby said. "I want to watch them suck your cock."

Adam filled her with a deep thrust and slowly pulled out. He switched places with Marie, spread his legs wide, and gestured for his wife and brother-in-law to crawl between his legs and put their mouths to use as they'd done so many times over the past few days.

"Come," Marie said as she looked at Christian. "Join me. Let's show them how desperately we want this, let's prove to them that they deserve to create a baby together, that we're more than willing to give them that gift."

It had long since stopped being odd to hear words like that from his sister, so Christian didn't hesitate to crawl between her husband's legs so they could both fellate his cock.

"That's so beautiful, baby," Ruby said as she reached out and caressed his face while he licked and kissed his way up one side of Adam's cock while Marie worked on the other. Their lips met over the head and their tongues danced just a little, though they were both focused on the pleasure of the man sitting in front of them.

"It feels like this was always where this was meant to end up, doesn't it?" Adam asked.

Ruby rested her hand on his chest, kissed him softly, and said, "It does. I suppressed my desire for this because it seemed too risky, but you're right. I think I've wanted this from the first time you had me, Adam. I think my body has known that you were always destined to be the one to give me a baby."

Christian's cock throbbed as he experienced what felt like the ultimate humiliation. What would have been painful for another man translated into pleasure for him, though, and it seemed that the same was true of his sister, who'd shifted to making love to her husband's balls with her lips and tongue, which gave Christian the opportunity to suck Adam's cock and show his eagerness to surrender completely to Ruby's deep desire for her brother-in-law.

"It turns me on to watch you suck his cock, baby," Ruby said as she reached down, put a hand on the back of Christian's head, and applied a little bit of pressure. He went deeper, taking as much of his brother-in-law's dick as he could, right up to the point that he gagged.

"Look at him," Ruby continued. "Look at him sucking your cock. Look at him choking on it. Look at how badly he wants to be good for me, for us. Look at how badly he wants to show his devotion to our desires. Look at how badly he wants to worship you, to suck you, to leave you covered in his spit so you can fill his wife's pussy with ease and get me pregnant."

Christian gagged once more and had to pull back. Marie happily took his place, doing so in a manner that struck him as a little competitive, as if she wanted to show her husband and sister-in-law that she too was devoted to their pleasure.

"Christian, baby, eat my pussy," Ruby instructed. "Put your tongue inside me. Taste me before he fills me with his seed, for you won't be cleaning me again until I'm pregnant with his baby."

Christian moved between his wife's long, lovely legs and put his tongue inside her. She put a hand on the back of his head and smiled as he worshiped her, soaking up her juices and spreading his saliva to ensure she was completely and utterly soaked by the time Adam entered her once more.

"This makes perfect sense to you, doesn't it?" Ruby asked. "You've probably known instinctively just like I have. On some level, you probably knew when you heard me sucking Adam's cock in the wood shed. You knew that if I was willing to do that for him - if I felt a deep-seated need to do that for a man like him that I almost certainly would feel a need to have his baby in me at some point."

Christian had known Ruby's feelings for Adam were different. He'd known from the desperation of her desire. They'd fucked whenever they could get a spare moment on that Christmas vacation. They'd fucked with such intense need for each other that it made perfect sense that they'd come around to the place they were in, that making a baby - and eschewing doing so with their spouses - was the logical destination for their relationship.

"I need you inside me, Adam," Ruby said. "I need you to cum inside me."

Marie instantly removed her mouth from her husband's cock and Christian backed away from his wife's pussy. He sat on his knees at the foot of the bed as Adam once again entered Ruby in missionary. They kissed as he filled her slowly and Marie moved next to Christian so they could both watch their spouses procreate.

"It's beautiful, isn't it?" Marie asked as she took Christian's hand and squeezed it tight.

"It is," he replied. His gaze remained fixed on the sight of Adam's cock slowly moving in and out of Ruby's pussy. Her hands moved down his back and up once more before they entwined in his hair while they shared a deep kiss.

"They're making love, Christian," Marie said. "They're making love and they're going to make a baby while we watch."

They held hands and watched the slow, beautiful lovemaking of their spouses. They witnessed the passion that had developed over a yearslong affair come to a head in that moment in the form of the most intimate, erotic, beautiful sex.

"I love that this turns you on as much as it turns me on," Marie noted softly as she leaned a little closer.

Christian looked down at his cock and noted how hard it looked and how swollen the head was. A drop of precum rested at the tip and there was a small stain on the sheets from the others that had fallen.

Marie reached out and ran her finger through the precum on the sheets before taking it between her lips and sucking it clean. She smiled, reached out once more, and gently brushed the head of his cock to soak up more precum and once again sucked her finger clean.

"Do you want to taste me?" she asked.

Christian's heart pounded as he met her gaze. The sounds of lovemaking filled the bedroom and his mind felt foggy with lust. He nodded.

Marie took his hand and guided his fingers between her legs. Ruby and Adam both moaned as their orgasms neared. Christian's hand trembled at the notion of touching his sister's pussy, and yet he didn't stop her from guiding his fingers between her labia and pressing them inside her.

"Can you feel my desire?" she asked softly.

Christian nodded as he buried his fingers in her pussy.

"Adam...I'm close...please, cum inside me," Ruby begged. "Please, cum in my pussy. Give me your baby, Adam. Get me pregnant."

"Taste me," Marie said softly.

Christian pulled his fingers from her pussy and pressed them between his lips. He tasted her sweetness on his tongue and turned his attention to the sex unfolding in front of him. Marie did the same as their spouses very obviously neared their climaxes.

"Oh my god, Adam, I'm cumming!" Ruby cried out. "Fuck...fuck...I'm cumming!"

Adam sped up his thrusts and a few moments later buried his cock inside her. They came together while Christian sucked his sister's juices off his fingers and watched another man attempt to impregnate his wife. His cock throbbed so hard it actually hurt a little, and with that pain came a sense of uncommon bliss that he wanted to experience so much more of.

He glanced at Marie and saw the same kind of joy on her face as she very slowly rubbed her clit. She seemed intent on keeping herself in a place of intoxicating arousal without going over the top and pursuing her orgasm.

Adam remained inside of Ruby long after they'd cum. They kissed, caressed each other, and whispered words of affection as they basked in the aftermath of their first sexual encounter while in pursuit of a pregnancy.

Christian remained transfixed with the sight of his wife's pussy filled with his brother-in-law's cock. A little of Adam's cum had leaked out of her, drawing greater attention to the idea that they'd had fully unprotected sex and were desperate for it to have resulted in impregnation, in another man having seeded Ruby's womb.

Eventually, Adam pulled out and Ruby quickly cuddled up with him. They shared a handful of soft kisses and she ran her fingers over his chest and stomach as a look of content settled over her face.

"I'd like you to extend our booking, Christian," Ruby said. "We're going to stay until I'm pregnant with Adam's baby."

"Okay," Christian replied. He couldn't think of anything he'd enjoy more than serving his wife and brother-in-law as they worked on getting pregnant.

"You two will do everything you can to ensure that we get pregnant," Adam added.

"Yes, we will," Marie replied.

"There will be no cleaning of my pussy until Adam's seed has taken hold inside me. I know you both enjoy that so much, but you'll have to wait to claim that pleasure," Ruby instructed.

"Of course," Christian replied, though he knew it would be exceedingly difficult to go so long without an orgasm. "We'll do anything and everything you need."

Ruby kissed Adam once more and they both turned to their spouses and smiled. "We know," Ruby said. "Now clean Adam's cock, and then you can suck him together until he's hard again."

Christian looked at his sister and they both smiled before moving between Adam's legs and working together to clean him. They'd do as they were told. They'd lick all the cum and pussy juice off of him, get him hard again, and watch their spouses fuck once more. They'd to that again, and again, and again - for weeks if necessary - until Ruby was pregnant.

Christian wasn't sure what would happen once that day came, but he knew his life and marriage had changed, and changed for the better. He'd almost certainly be closer to his sister and brother-in-law as the future unfolded, and he'd live a far more exciting, thrilling existence, which was everything he wanted.

The End.
