Scott/Sandy: 42.

Jack: 22.

Leah: 21.

Plap... plap... plap rang through Scott's ears as he sat on the sofa, engorged cock in hand, in disbelief at the sight before him. His wife, Sandy, was lying on the bed before him, flat on her back, her chest heaving as she loudly moaned over and over. Beside him sat his daughter, Leah, knuckles deep in her own pussy as she sighed softly. And between his wife's legs, ruthlessly thrusting back and forth on his way to orgasm, was Leah's boyfriend, Jack.

***

Scott and Sandy were no strangers to other people in the bedroom. Almost their entire relationship, they had been engaging in some variety of swinging. Scott would sometimes actively participate, but he was often content to be a stag and watch Sandy enjoy other men and women. Even after Leah was born, they still found time on "date nights" to rendezvous with old friends and partners for some action.

Then Leah went off to college and met Jack, who had grown up on the other side of town and attended the rival school. The two quickly became inseparable, and both ended up moving back home as Leah pursued an online degree and Jack commuted to a nearby smaller university. He was a familiar presence at Scott and Sandy's house, both for being their daughter's boyfriend and for his newfound interest in piano. Sandy had grown up playing piano, and offered to give him lessons on the weekends. Scott noticed the two being very close and Jack eyeing his wife on several occasions, but he thought nothing of it. After all, he couldn't deny his wife was gorgeous.

Scott and Sandy had discussed the pair in terms of swinging, but never in any seriousness. There are some lines that just aren't meant to be crossed. Still, it was an interesting fantasy. Sandy did find Jack appealing, and Scott, sick as it made him to think about, thought his daughter very much took after his wife. Then, one day, they found out they weren't the only ones having these discussions. Leah approached them, asking to talk before dropping the bombshell that not only were she and Jack interested in swinging, but they wanted to try it with them. It was a long conversation with a lot of hesitancy, but she won her parents over by mentioning that she and Jack wanted to try for a baby, and she wanted to see Jack impregnate Sandy.

Scott and Sandy both had breeding kinks. They had always played it safe while swinging, and Leah was the result of Sandy's only pregnancy. Still, the thought of someone knocking up his wife turned Scott on like nothing else. Sandy had expressed her own interest, but they hadn't found the right person. So they jumped at the opportunity. Optimal dates were calculated, and soon Sandy and Leah were both ovulating.

Which led to the current scene.

***

"Are you positive you want to go through with this? There's no going back from it." Sandy asked.

"I'm positive, baby. This is what we've always wanted." Scott reassured her.

"I never thought that would come with our daughter in the room."

"Are you sure you're okay with involving her?"

"Just make sure you're not getting her pregnant, now." Sandy chuckled.

The two kissed each other before a knock on the door announced Jack and Leah's arrival.

"Hey guys!" Jack said as the two walked in.

Sandy moved over to him and slipped an arm around his waist. Leah moved over towards Scott, watching the other two and smiling.

"Are we ready to get this show on the road?" Scott asked, "Everyone still okay with doing this?"

"I want nothing more," Leah said, looking up at him.

"Oh yeah." Jack and Sandy muttered in agreement.

"Okay, I told Jack Mom gets to go first. I want her to get the most sperm." Leah ordered as she moved towards the sofa.

She began removing clothing, and Scott did the same beside her. A quiet gasp involuntarily escaped him as she freed her perky tits from her bra. They were a little larger than Sandy's, and he couldn't help but imagine what they'd look like when she was pregnant. The two continued undressing, and Leah smirked as Scott's soft cock was revealed. They sat down on the sofa and turned their attention to their partners. Jack had removed Sandy's top and bra as they passionately kissed, and they were moving on to each other's bottoms. Leah gasped as her mother's pussy was uncovered. Her hand reached for her own, and Scott's hand moved to his dick. Then Sandy pulled off Jack's boxers, and she and Scott both gasped as his long, flaccid cock slapped against two already-swollen balls.

"Oh, you're really backed up! Leah, honey, we gotta let your poor man release some of that." Sandy teased as she ran a hand up and down Jack's gradually hardening shaft.

"You think we should, daddy? It's gonna happen inside mom... and me." Leah asked.

"Absolutely, baby. I can't wait for you to fulfill your fantasy." Scott replied.

They sat down on the couch as Sandy and Jack resumed making out, with her hand on his dick and his massaging her clit. Their tongues intertwined as they pressed their chests against each other, obscuring the front of their crotches from the onlookers. Scott turned his attention to getting himself hard, while Leah massaged her nipples with a soft sigh. She turned her head to see her father fully erect.

"Wow, daddy, you're thick!" She said, surprised.

Jack and Sandy both turned to him, and Jack's own hard dick was revealed. It was definitely longer than Scott's, but around the same girth, if not slightly thicker. Scott wondered if Jack would be able to go balls deep in Sandy or not.

"Mommy, can I try daddy's dick? I think it's thicker than Jack's." Leah pleaded.

"As long as he doesn't cum in you. Unless you want your father to get you pregnant." Sandy replied.

"I mean..." Leah said, "... could he?"

"We talked about it, and I'm okay with it," Jack said.

Sandy and Scott were speechless. They turned to look at each other.

"I guess it's your cum, your call," Sandy said.

Scott thought for a moment.

"We can both cum in her. That way, we leave it up to fate." He said to Jack, extending his hand.

"Sounds good to me," Jack replied, shaking it.

Leah bit her lip as she wrapped a hand around her father's dick. He took the opportunity to fondle her tits as Sandy knelt down and lowered her mouth onto Jack's cock. Leah soon did the same, struggling to fit her lips around Scott's girth. They continued until both cocks were fully hard and wet. Scott and Jack returned the favor, taking their partners' places and tonguing their pussies. Soon, both were soaked and Leah came on her father's mouth.

Jack pushed Sandy down onto the bed on her back. He lined himself up between her legs, and after teasing her pussy with his cock head, slowly inserted himself into her. She moaned loudly as he continued pushing deeper.

"Oh my god, you're so deep!" Sandy gasped.

Meanwhile, Leah spread her legs wide as Scott stroked his cock in front of her.

"Are you sure you want me to fuck you?" He asked one last time.

"Absolutely, daddy. I want you to fuck me until you cum in my fertile pussy." Leah reassured.

Without hesitation, Scott breached his daughter's pussy. He was immediately overwhelmed by her tightness. Her chest heaved as she sighed in pleasure, and Scott began to rhythmically thrust in and out. Behind them, Jack pounded away at Sandy's pussy, intent on building up as big of an orgasm as he could. It was difficult not to cum with her walls pushing in on his cock as he speared her, especially with her own orgasm nearing.

"Fuck, don't stop, I'm about to cum!" Sandy commanded.

She came moments later, clamping down on Jack's dick as she was lost in ecstacy. Realizing it was only a matter of time before he also would cum, he continued thrusting through her orgasm. Scott did the same thing, pistoning away into his daughter until Jack said the words they were all waiting to hear.

"I can't hold back anymore! I'm gonna cum!"

"Oh! Cum inside me! Get me pregnant!" Sandy yelled.

Scott pulled out of Leah, who jumped up from the couch and stepped over to Jack. She wrapped her arms around him as he continued fucking her mother.

"Please cum in my mom, okay, baby? Please knock her up!" She begged.

Suddenly, with a grunt, Jack stopped thrusting. Scott watched as the exposed part of his cock pulsated over and over again as he shot his load into Sandy. His orgasm seemed to never end, and every time Scott thought it was over, he watched the cock in his wife pulse again. Finally, Jack pulled out, and even then, a small spurt of cum emerged from his cock and dribbled onto Sandy's leg. Having nowhere to go, a glob of his seed flowed out of her pussy.

"Oh my god, baby, she's overflowing!" Leah said, hugging her boyfriend.

Scott walked up and took Sandy's hand in his.

"Hi." She said, turning her head to him and smiling.

"Hi." He replied.

"How are you feeling?"

"Amazing. This is more than I could've dreamed of."

"Me too. Now go give your daughter the cum that made her."

"I love you."

"I love you too."

Scott pulled away, stepping toward Leah, who was kissing her boyfriend.

"Oops, it looks like it's time for my breeding. Will you let my mom get you hard again while my daddy cums in me?" She asked Jack.

He nodded, sitting on the bed next to the woman he had just inseminated. She took his deflating cock in her hand and began to slowly stroke it. Scott and Leah moved back to the couch, where she got on her hands and knees with Scott kneeling behind her. He once again entered her, resuming his rhythm. His balls slapped against her clit as they synced with her desperate moans.

The sights and sounds were enough to push Jack to getting hard once more. Sandy rolled over and put his cock in her mouth, intent on keeping him ready to breed her daughter. Her husband's ragged sighs told her he wouldn't last much longer, and soon his seed would also be seeking Leah's womb. She knew Scott was virile; Leah had been conceived on their first try. Jack faced quite the challenge.

"Uh, I'm gonna cum." Scott muttered.

"Yes! Put a baby in me!" Leah cried.

"Breed our daughter, honey," Sandy said, rising off Jack's dick and flipping around to watch as he did the same.

Scott pounded away as the sensation of orgasm grew through his dick. The feeling of his daughter's pussy and the thought that he might get her pregnant were driving him full speed towards exploding in her. He didn't have time to give another warning before his legs buckled and his cock flexed. Rope after rope was launched from him and collided with her cervix. Time stopped as he released all he could of the same cum he had made Leah with long ago.

"Holy fuck, you're still cumming!" She shouted in disbelief, breaking Scott out of his trance.

He was still cumming, though he was almost done. He shot another spurt, then thrust a few times to coax a couple more out. Finally, he pulled out. A thick stream of cum followed him, pooling on the couch. He stepped aside, allowing the others to see the overflow. Jack got up, stiff dick in hand, and walked over to Leah. Kneeling down, he pushed her legs farther apart and watched Scott's cum trickle out of her.

"Hey, baby." She said, looking down at him.

"Hey." He replied, still focused on her pussy.

"My dad just put so much in me. He's gonna get me pregnant if you can't do it first. I need you to save me from raising his baby, okay?"

Jack didn't hesitate. He quickly stood up, gripped the base of his cock, and slid it into his girlfriend. Leah yelped as she was suddenly speared, then began to rock her hips back and forth in sync with his thrusting. Scott sat down beside his wife to watch his daughter get railed.

"Ah! Yes, please knock me up!" Leah cried.

Jack would normally take his time fucking his girlfriend, making sure she was comfortable and could get off. But now, all he cared about was cumming. He wasn't sure how much cum he had left after putting a big load in Sandy, and any moment he wasn't cumming could be the moment Scott's sperm reaches Leah's egg instead. So continued pounding away, desperately trying to reach orgasm.

They continued like this for several minutes, while Sandy slowly stroked Scott's spent cock. Jack was close to cumming, but he couldn't quite reach the point of no return. Then, Sandy teased Scott.

"Did you really have to cum that much in our daughter? You know it doesn't take that much to knock her up." She laughed.

"Hey, when I do a job, I do it well." He replied, "You said breed her, so I made sure she's bred."

"Ugh, I'm so close to cumming!" Jack grunted.

"Please fill me! Please replace my daddy's cum! Do it for me, baby?" Leah cried, pulling her legs toward her head to give him deeper access to her pussy.

He suddenly stopped and groaned, bucking his hips as he began releasing cum balls deep in his girlfriend. He thrust a few times as he came, trying to coax more ropes out. His load wasn't as big as his first one, but he was still surprised by how much he unloaded.

"That's all I had left; hopefully, it's enough." Jack gasped as he stepped back and caught his breath.

Scott and Sandy got up and walked over to their twice-inseminated daughter. Her pussy and thighs were covered in cum that had leaked out of her.

"Either way, I'm so glad it's one of you that's getting me pregnant." Leah smiled.

She put her hand up to Sandy's belly.

"And I'm so glad Jack could help mom, too!"

"Of course!" Sandy said, grabbing Jack's deflating cock, "He did such a good job."

Scott held Leah's other hand.

"Know that you two are always welcome to join us again." He said.

"Of course, daddy. We'll do this again soon. Although the breeding may have to wait at least nine months." She replied.
