Unearthly Secrets Ch. 08

Literotic asexstories – Unearthly Secrets Ch. 08 by FrostyPen23,FrostyPen23 Amy was humping her son in her bedroom when her phone began to buzz. It was about ten in the morning. The house was still empty besides the two of them.

“Ah, shoot. I should really answer this,” she said.

“Don’t stop,” he pleaded, and so she didn’t, reaching down for her buzzing phone at the same time as she continued riding him.

“Hey, ugh, Karen, how are you?” Amy said into the device, putting it up to her ear.

She was straddling her son, rising and falling on him slowly, her back arched as his rod pressed into her in all the right spots.

“Amy! Girl, I’ve been meaning to call you. I wanted to see if you were around today?” the muffled voice on the other end replied. “I was thinking brunch?”

Jack could only stare up at his mom, who was riding him in the reverse position, as she carefully controlled her breathing so as not to appear suspicious.

“Oh, shoot!” she said, most likely insincere. “I’m busy today, Kar. Phil is away on a work trip, and Jack is back in town.”

“What? Since when? Oh, Amy, that must be so nice to have him around again!” Karen replied.

“Aagh… yes, it… uughh… is!” Amy was taking deep breaths between every word.

“He’s staying with us for a while until he figures out his next moves,” she continued.

Jack rocked her hips gently with a few thrusts of his own, not letting her forget what they were still doing.

“You know, Karen, I hate to rush you off the phone but I’m actually out with Jack now and I should probably go. Can I call you later?”

“Sure thing, hon,” her friend acknowledged, and they said their goodbyes.

Amy threw the phone on the mattress, and bent down onto her elbows.

“Sorry, sweetheart. It was just Karen. She’s been calling me non-stop since yesterday.”

“It’s… umph…. fine, mom. I just didn’t want to… ugnnhh… stop,” Jack answered.

With Amy on all fours now, he had a perfect view of her spread ass, watching his cock slide in and out of her pussy as she moved. He grabbed either cheek and squeezed hard, spreading them apart even further. Her tiny ass hole looked like a perfect, pink little hole. He wondered if she enjoyed anal as much as his sister did.

Squelch, squelch, came the sound of their union, her moistness lubricating his whole length.

“Me… neither… aaghhh! Fuck!” she cried, slapping her ass on him now with alacrity.

They had been going for nearly twenty minutes now, and it was already their second romp of the day. Their morning had begun rather lazily, slowly grinding up against one another as they awoke, the sunlight gradually filling his mother’s bedroom. He had filled her, too, both of them laying on their side, as he had with his aunt the first time. Afterwards they had showered and made breakfast together, and they talked about their plans for the day. Jack not soon after proposed another round, and Amy, being the giving mother that she was, obliged her son, leading him back to her bedroom where she promptly mounted him once more.

Ever since he had entered her for the first time the day before, it was like a switch had been flipped. She was insatiable when he was inside her. She said and did things he had never seen nor heard her do. He slapped her ass as she continued bouncing on his shaft, and she merely growled in ecstasy, redoubling her efforts on him.

“I can’t believe we’re… ugh… doing this…” she bellowed, her head facing the opposite direction.

“Me neither… hmph! I… ungh! Love it… I love you!” he grunted, giving her a few extra forceful thrusts to let her know he really meant it.

She whimpered and moaned in response.

“I love you too, sweetheart… oh! Shit, yeah!” she cried. “I forgot how good it feels to be filled with the true seed.”

She was referring to his grandfather, of course. The true seed was the name for Ultari sperm, the true reproductive ingredient that really mattered. Their bodies had evolved to find it pleasurable, he had learned in one of his many lessons with Nana. The taste, the smell, and even the feeling of it inside of you–it was all an aphrodisiac for the women in his family. Spraying the back walls of his mother’s cervix was reigniting neural pathways that hadn’t been triggered in years, releasing a complex cocktail of hormones that not even Phil, her husband, could have activated on his best day in bed.

“Mom, if you keep talking like that you’re gonna make me-” he started, but he realized it was already too late before he could finish.

“Cuuuummmm!!!! Oooohhhhh fuckkkk!” Jack wailed, clamping down on his mother’s hips so that she couldn’t move. He felt his tip pressing up against her cervix, but he didn’t care. He could feel warm streams of his semen flooding into her as she moaned and fidgeted on top of him.

“Jack… oh, baby!” she cried, clearly having some sort of intense reaction to his ejaculate as well.

“I can feel it! I can feel it!” she exclaimed.

He was humping up into her now, controlling his speed as he peaked, then slowing down as the sensations came to their natural conclusion. She sighed loudly, soaking up the moment.

“I can already feel it leaking out of me,” she said. His cum was pooling around the base of his shaft. His mother carefully lifted herself off of him, taking care not to let anymore spill out.

“You made me cum really hard,” he replied, smirking.

“How do you keep producing this much?” she asked incredulously. He didn’t truthfully know. When he was with her, it was like his balls went into overdrive. It was probably evolutionary.

Amy looked over at her son laying next to her, his dick still half erect.

“Should we just lay here for another 10 minutes until you’re ready to go again? Or do you think you’re good for a while?”

Jack pondered her question. He felt pretty spent by now. Twice in one morning was a new record.

“I might be done for a while,” he answered. “We should probably go rinse off.”

His mother agreed, so they hopped into her shower together–much larger, elegant, and cleaner than his. Afterwards they made lunch and watched a television show while cuddled up on the couch. Some reality show that Jack couldn’t follow the plot of to save his life. He didn’t mind, however, as it gave him an excuse to lazily massage her tits. She didn’t seem to mind.

It was during that time while reclined on the couch that his phone buzzed. One new text message. It was from his aunt.

Are you free today? I have a few hours open if you wanted to stop by, it read.

He turned to his mother, still laying there with her eyes glued to the screen. He imagined his aunt’s fat ass bouncing on him again.

“Mom?” he muttered, and she glanced over.

“Aunt Kim wants to bond today, I think,” he said, flipping the phone around for her to read.

“Oh, okay,” she replied nonchalantly. “You can tell her no. You’re busy with me.”

Jack chewed on his lip.

“Are you sure she won’t get mad?” he asked.

Amy smirked.

“Tell her I said so. She won’t get mad at me. You’re my son, not hers.”

Jack blushed.

He nodded and sent another text back to his aunt.

Sorry, Aunt Kim. I’m kinda busy with my mom today. Rain check?

The text bubble appeared as Kim began typing a response, then disappeared. It started up again a few moments later.

Fine. she replied.

Jack felt his stomach drop. Had he said the wrong thing?

“I think she’s mad, mom,” he said. Jack read the message from his aunt out loud.

“She’ll get over it. You can see her in a few days once your dad is back in town,” Amy retorted.

Jack thought for a moment. Did he dare ask what was on his mind?

“You know…” he began, testing the waters. “What if we invited her over today? To join us?”

He was feeling bold, apparently. His mother’s eyes went wide, piercing him like darts.

“What was my stipulation about all of this, hm?” she barked, her words dripping with acid.

It was a rhetorical question. She answered it promptly for him.

“Your aunt, nor anybody else in this family, is going to find out about what we’ve been doing today. Did I not make myself clear enough yesterday?”

“I… I’m sorry. I know that,” he quavered, realizing how brash he had been. It was a stupid thing to even suggest. “I just thought that after that night at Nana’s house…”

“I know what you were thinking,” she interjected. “And I already told you before… No!”

Jack took the abuse. It was deserved. They continued watching the show together for a while before he felt his mother’s hand on his leg. Her face was glued to the screen, as if she wasn’t aware of what she was doing. Slowly it crawled its way up his inner thigh, brushing, then grasping, his growing appendage.

He groaned a bit, and her hand clamped around his shaft firmly.

“I need another round, sweetie,” she said, her eyes still fixed straight ahead.

“Uh… yuh huh,” he consented, trying not to bust in his pants.

“Come on,” she said, turning the TV off with her free hand, standing up, and taking him by the wrist up the stairs.

***

“From behind,” she ordered him, stark naked in her bedroom. She was bending over her mattress, her ass cheeks spread wide open as she propped herself up on her elbows. Her tits hung down to the sheets, swinging back and forth as she moved.

“Yes, ma’am,” he said, moving himself behind her fat, juicy peach. His dick slid in with ease, and the feeling of her cunt from this position was new and tantalizing. He probed into her hole in ways he hadn’t felt before. It was incredible.

She moaned as he penetrated her fully for the first time.

“Fuckkk… yes…” she cried, her head buried in the mattress.

He gripped onto her hips and dug in, using his hold to force himself even farther and faster into her. Her whole body began to rock in rhythm with his thrusts.

Slap, slap, slap! her ass cheeks clapped up against him each time.

He plowed into her like this from behind for several minutes. He had already came twice today and was finding it easier now to retain his stamina. He could probably last an hour at this rate.

“Keep going, sweetie… oooh! Just like that… yeah…” his mom continued moaning.

There was a creaking noise by the door. A sound of footsteps perhaps that Jack hadn’t noticed up until that point. He turned, half-expecting nothing. A simple glance, a response to a random stimuli.

Instead, he saw his aunt standing there, mouth agape. She was dressed in a light jacket and a pair of jeans. Her hair was done up in a bun, and she had a minimal amount of make up on.

“What the fuck, Amy?” Kim bellowed, stunned.

His mother turned around suddenly, pulled out of the orgasmic trance without warning. She screamed.

“Ahh!! Fuck, Kim? What are you doing?”

“Me?” her sister yelled back. “What am I doing? Amy, are you fucking him?”

Amy gave a defiant gasp. There was no sense in deception. They had been caught in the act. Red handed.

“Yes, Kimmy… we were. Are you going to go blab to mom about it now?”

Kim scoffed.

“Ha! Am I? I should, you idiot! Are you trying to get pregnant? At your age? Really?”

Amy put her face in her hands for a moment, groaning with frustration.

“No, I’m not trying to get pregnant. I’m safe right now. I’m not an idiot!” she retorted.

Jack just stood there, too surprised to butt in. This wasn’t his fight. He knew better than to get between two sisters.

Kim circled around, rubbing her forehead in disbelief.

“So this is why he wasn’t available today, huh? Because you’re too busy fucking him instead?”

“Oh, stop it with the sanctimonious scolding, Kim. You showed up unannounced and walked in on us. With no different intentions, I’m sure. I could have told mom about your bonding sessions with him, too. But I haven’t! You’re one to talk!” Amy shot right back at her sister.

This sent Kim into a rage, he could tell, but his mom did have a point. His aunt saw it too, it seemed.

Jack felt it was now appropriate to say something.

“Can you two just stop yelling for a second? Please?” he cried.

They both turned and looked at him for the first time, silent.

“I just… I just don’t understand what the big problem is. I love both of you. I don’t want you to fight over me, or keep secrets from each other. Aunt Kim, I swear to you that my mom and I have been careful, just like me and you were. We’re only doing this while my dad is out of town for the next few days. Then it’s back to business as usual.”

He turned to look at his mother, now.

“Can’t we just… keep this between us?”

His aunt sighed.

“Jack… hmph. I’m sorry, kid. I’m not going to tell your Nana. I was just… surprised. And suspicious. And a little pent up.”

“It’s okay, Kim,” Amy apologized. “I’m sorry. Really, this is fine. Let’s all just calm down.”

“Thanks,” Jack said, to both of them, the temperature already cooling off in the room.

“You know, Ames…” his aunt finally broke the stillness, a hint of playfulness in her voice. She gave her sister a suggestive look.

Amy’s face registered something in comprehension.

“Wha-? Oh, no! Absolutely not, Kim. I already told him no,” she defended.

This only made his aunt grin.

“Ha! So he’s already asked, huh?”

She turned to look at him now. Jack gulped.

“I guess great minds think alike, Jack.”

Jack was confused… was she referring to- Oh. She was, wasn’t she?

“Kimmy, stop it. I’m not that young anymore. I haven’t done something like that in decades,” his mother pleaded, still hunched over sat on her bed, buck naked.

“Oh, bull,” Kim replied. “Don’t tell me you’re gonna just sit there and watch.”

And with that, his aunt was stripping down in front of them herself, joining them in their nudity. Jack was reminded of how lewd her body was, and he felt the hairs on his neck stand on end.

“Kim…” Amy begged one more time, but even she knew it was futile.

His aunt swayed over to the bed, bending down and kissing his mother. Their lips locked and slid over each other for several seconds, their eyes closed in deep passion. He heard his mom moan softly.

“He’s the seed of our family. We shared it before, and we share it now,” Kim whispered aloud.

“God dammit, Kim…” was all she responded, past the point of return. Her breathing was growing heavy again.

“Come on, Jack,” His aunt called.

Jack approached the bed now as his mother scooted herself farther back, spreading her legs wide. His aunt bent down over the mattress, burying her face in his mother’s pussy as she flared her own ass upwards towards him.

Amy looked down at this human centipede and let her eyes roll to the back of her head. Kim turned around, her eyes seducing him from over her shoulder. She bit her tongue.

Jack grabbed his aunt by the waist, just as he had his mother only ten minutes prior. He felt her nestle up against his crotch, burying his cock between her cheeks. She moved her gaze back to her sister’s cunt and returned to her work.

Jack stuck two fingers cautiously into Kim’s warm hole, feeling if she was sufficiently ready for him yet. She was. He grabbed the base of his shaft and gently guided the tip inside of her. She shuddered as he entered.

He pushed all the way inside, and Kim began rocking her hips back and forth, doing some of the work for him. He tried to match her pace, slapping each time they met. A low, guttural groan emanated from his aunt as she relaxed around his girth.

He looked down at his mom’s pussy, Kim’s lips smearing juices everywhere. His mom was in a state of pure bliss. God, he loved her. He loved them both.

“Fuck… yeah… ughh…” he grunted with each thrust, finding the energy somewhere to rail her even harder than he had his mom. He was laying it on her now, fucking her so hard he feared it might leave a bruise. His aunt wasn’t even licking his mother’s clitoris any longer, she was so overcome with pleasure. Her tits flung backwards and forwards, slapping together and against her chest.

“God dammit… Jack! Ayee!! Fuck!!” she squealed. She was gripping onto the bedsheets for dear life.

“I’m gonna… fucking…. bust!” he cried back in response. Kim then suddenly pulled forward, laying on top of her sister. Jack’s cock unsheathed itself from her with a plop!

“Wha-?” he tried to say, but Kim was already a few steps ahead. He was on the verge of cumming. What was she doing?

“In your mother!” she commanded, making room for him by rolling off of Amy.

Jack didn’t need to think clearly about the instruction. He saw his mother’s wet cunt in front him, desperately in need of a cock, and he laid down onto her fully inserting himself to the hilt without second thought. Amy merely whimpered under him as he buried his face in her bust.

His hips did the rest of the work, pumping away into her rapidly as his semen was dutifully shot deep into her. She moaned like a virgin with each release.

Kim laid next to them, admiring.

“Oh my god, its leaking out already!” she exclaimed, driving her sister even more wild. Her son was still humping her furiously.

He felt himself give her the last of his seed and let himself sink into her chest. Her arms appeared around him, hugging him close to her. He took slow, deep breaths. He needed a moment to rest. He loved how it felt to melt into her soft, curvaceous body. How her enormous breasts engulfed him.

“Ha…” Amy sighed, clearly exhausted, too. Her eyes remained closed.

“That felt so damn good.”

“Next time, I get his seed,” Kim said.

Amy just laughed.

“Fine,” she replied.

The sisters giggled like giddy school girls.

“Are you okay in there?” Kim finally asked of Jack, noticing he had been suffocating between his mother’s breasts for some time now.

He lazily lifted a wrist, giving the thumbs up sign. Both women chuckled.

“He’s more glued to them now than when he was a baby,” his mother chided.

“That’s hard to believe,” Kim laughed.

They let him continue to motorboat while they stretched and relaxed. He was still deep inside Amy, his cum slowly leaking out. After a few minutes of rest, they gathered their strength again and peeled off of each other. They were a ball of sticky, naked flesh.

Kim stayed for dinner and kept them company. She had proposed another round shortly thereafter, but Jack was well and truly spent after his third burst of the day. She was disappointed, but understanding. Amy invited her to stay the night instead. Perhaps the sisters would reignite their own flame together in his absence, Jack thought. Nonetheless, he was already in bed, exhausted from a day’s worth of raw sex. He slept well that night, only hearing the occasional moan echoing down the hall from his mother’s room.

As the sun rose, he awoke with it. He yawned, stretched, and got up to brush his teeth and dress. He wandered down to his parents’ room with sleep still in his eyes. Carefully he peered in to see his mother and aunt dead to the world, both snoring loudly under a mess of sheets and blankets.

Must’ve been a wild night, he thought privately. He tip-toed back into the hall as quietly as he could.

He wandered down stairs and made a bowl of cereal, turning on the tv to watch whatever sports highlights were playing that week. It was around nine thirty in the morning by now, and Mom and Aunt Kim still hadn’t come down yet. Perhaps they were fooling around together some more. Part of him wanted to join in, if so. Before he could rouse himself off the couch, however, his phone began to ring. It was Emily.

“Hey Em, what’s up?” he answered, his voice still dull.

“Hey Jack. Is Mom’s phone dead or something? I tried calling her all morning.”

“No,” he quickly replied, “She’s just still sleeping I think. She had a late night.”

“Who? Our Mom? Okay, Amy!” he heard his sister laugh, lovingly mocking their seemingly milquetoast mother.

“Well, I wanted to get both of you guys on the phone but maybe I can just wait until later.”

Jack could sense something in her tone. She was holding something back.

“What’s going on, Em? Everything okay?” he asked.

“Heh, everything is great, dude. Agh!”

He heard her voice grow more quiet, as if she was talking to someone else there next to her.

“Should I just tell him anyways, Fred?” he heard her whisper. There was some kind of grumbling in the background.

“Jack?” she was loud and clear again.

“Yeah?” he asked again, still unsure what was happening. His sister began to shriek with excitement.

“Me and Fred and are getting married!!” she squealed. She sounded exuberant.

“What?! No way! Congratulations!” he exclaimed, taken aback.

“Uh huh! He proposed to me last night. It was perfect! And the ring is gorgeous,” she continued gushing.

He heard Fred’s voice on the other end now.

“Hey buddy, I’m excited to finally be brothers!” he said. Jack barely knew this man. He didn’t let the snarky thoughts bubble to the surface though.

“Woah!” he responded, “Me too! I’m so happy for you guys!”

“Thanks, bud!” Fred said.

Jack’s mind was filled with images of his nude older sister, his cock buried all the way down her throat. Or perhaps his cum leaking out of her gaping, convulsing asshole. An asshole that he had torn open himself. Her mewling, slutty reaction to his cock. The way she begged and moaned for it. This poor guy had no idea he was just a pawn in a deeper, more ancient game. Just like his own dad.

Emily’s voice returned to the speaker now.

“Okay, well, that’s all we wanted to say. Don’t tell Mom yet. Just let me call her when she wakes up and tell her first.”

“No problem,” he said. “My lips are sealed.”

She made a mwah sound and said goodbye. He hung up. Everything was about to change. Life wouldn’t ever be the same soon. Was he ready for it all? He stared out the window, half worried yet excited. He was truly starting to become a man.

***************

“Okay, your turn,” Amy said to her sister. They were on their knees in front of the sofa down in the basement, kneeling on either side of Jack. He watched in amazement as his topless mother and aunt went back and forth on his cock, showcasing their skills in oral pleasure.

It had been two days since Aunt Kim had come over, and she hadn’t left. The morning Emily had called to tell him the big news was mostly a blur throughout the rest of the day. After that call, he had went back upstairs only to catch the sisters engaged in the act, which he promptly joined and exacerbated. That time he fulfilled his promise to Kim, keeping the scales balanced, and deposited his load into her desperate pussy.

They fucked twice more that day, barely leaving the bedroom except for meals. Jack traded one woman for the other, back and forth, trying all sorts of wild positions and contortions. He finished inside each of them once more that day before his cock was permanently limp from exhaustion. They let him just cuddle and grope their luscious bodies until sleep consumed him.

They were now consumed in a competition of sorts. His aunt was currently gagging while his cock head slammed up against the back wall of her throat, unable to go deeper. It felt amazing to Jack still, but it certainly wasn’t the same as his mother’s ability.

She plopped him out of her mouth for a brief moment to speak.

“You’ve gotta be close to cumming, boy!” she exclaimed.

Jack merely chuckled, pressing his aunt’s head back down onto his crotch. She accepted his cock again without protest.

“I don’t know, auntie,” he replied. “Keep going.”

“I’m going to make him cum,” his mother declared, kneeling next to her. “You’ve only got thirty more seconds.”

Kim began to choke rapidly now, violently gagging on his pole and hoping for an orgasm. It was bringing him close, he had to admit, but after all the sex he had engaged in these past few days it was easier to hold off the climax.

“Time’s up!” his mom shouted, grabbing her sister and pushing her out of the way. She leant down as if to pick up where Kim had left off.

“Mom, I want to use your boobs this time,” he said before she could swallow him whole.

“My boobs? What, my mouth isn’t good enough?”

She was teasing him.

“Jack, what the hell? You’re giving her an unfair advantage! I would have let you fuck my tits, too!” his aunt cried.

Amy was already wrapping her sagging breasts around his shaft.

“You guys…” he moaned, his eyes sinking to the back of his head. “I don’t know if I will cum from just one of you at this rate. Why don’t you both use your boobs at the same time?”

Amy paused, looking over to her sister. Kim pondered it for a second.

“The same… time? We haven’t done that since… dad?” she asked her sister, giving her a smirk.

“Fine,” his mother conceded, making room for Kim to join.

Both women now plopped their heavy tits on his lap. Jack loved the way they laid on his thighs: so plump, yet spread out against his skin. They angled themselves so that his erect penis fit firmly between all four breasts.

“Like this, sweetheart?” his mother asked sincerely.

“That’s perfect, mom,” he exclaimed, moaning now as he thrusted up between them.

The two women held their tits tight around his shaft as he did most of the work. They watched as his throbbing, purple head peered above their cleavage with every thrust.

Slap, slap, slap, their heavy tits sounded each time skin met skin.

“Fuck! This feels so fucking good!” he cried.

“He’s close, Kimmy. Get ready,” he heard his mother say. There was something so sexy about the way she said it, about the way she knew his body almost better than he did. That she could make him feel this amazing.

“Cover our tits, Jack, come on!” His aunt moaned while picking up the pace.

“Aghh! Cumming!” he managed to shout before the white ropes started to erupt. Pulse after pulse splattered across their tits, webbing them in his semen.

“Ah!” Kim exclaimed excitedly. “So much! What the hell?!”

His mother just laughed, watching with content pleasure as her tits were coated as well.

Jack took a few deep breaths as his orgasm subsided, needing a moment’s rest. But Amy and Kim demanded answers.

“So who won, huh sweetie?” his mother prodded.

“It was absolutely me, Amy,” his aunt chided.

“You both won. You made me cum together,” he answered quite politically.

Kim slapped his thigh playfully.

“Coward. We’ll make you give a real answer one of these days.”

Jack grinned, unperturbed.

“One day, but not today,” his mother cut in. “Phil gets home in an hour or two. It’s time to get going, I think, Kim.”

“Shoot, you’re right,” her sister replied, checking the time herself.

They untangled themselves and Jack offered some paper towels to clean up.

“Not needed, sweetheart,” his aunt responded, leaning over and cupping his mom’s tits to her mouth. She began licking up his cum off of her breasts until they were dry.

“Jesus christ, I think I almost came again,” he said as he watched. Kim gave him a devious grin.

****************************

By the top of the hour, his aunt had left. His mother advised him to go down to the basement and play his video games while she made herself look busy in the kitchen. It was forty-five minutes later before he heard his dad trudge through the front door.

“Sweetheart, your father is home!” he heard his mom shout down the basement steps.

“Coming,” he replied!

“Hey, bud, how has the last week gone taking care of your mom?” his dad asked as he entered the kitchen. Amy was stirring something on the stovetop while his dad had his laptop open at the counter. He hadn’t been home for ten minutes and was already checking his emails.

He glanced at his mother for a moment. He had taken care of her, alright. He cringed thinking about his dad finding out what had been going on behind his back.

“It was awful,” he jested, trying play it off coolly. Phil chuckled.

“Ha, I bet.”

Jack wondered if some small trace of his cum was still dried on his mom’s tits under her shirt.

“How was your trip?” he asked.

“It was great,” his dad replied. “I met some clients and secured two really big contracts for us this year.”

“Does that mean they’re going to pay you more finally?” his mother chimed in, sarcastically. Phil laughed.

“Ha, no, probably not. But I’ll be their best bet to replace Cunningham when he retires.”

Phil droned on for another few minutes about his coworkers and office politics. Who was lined up for promotion, who was going to get fired, blah, blah, blah. Jack didn’t care one iota, even when he tried to pay attention.

“I’m gonna go to bed, sorry dad. I had a long day,” he said. His balls ached from what had felt like a non-stop sex marathon this past week. He needed a respite.

“No worries, bud. G’nite.” His parents continued chatting in the kitchen as he hiked up the stairs and collapsed on his bed.

******************************

Jack awoke to his mother opening the shades in his room. She was already dressed for the day in a purple blouse and jeans. The sunlight flooded the room and temporarily blinded him.

“Agh, mom!” he cried, startled.

“It’s nearly ten AM, Jack. You’ve got to get moving.”

He groaned, pulling the blankets up over his face. She pulled them back down, sitting on the edge of his mattress.

“I’ve got bacon and eggs downstairs waiting for you.”

She knew this would be the motivation her son needed. He began to stir.

“Besides, we need to talk about your sister.”

“Did she call you?” he asked, his voice still hoarse from sleep.

“Mhm, she and Fred both did. I heard the exciting news. Now come on, get your butt moving. I’ll explain more in the kitchen.”

A few minutes later, Jack was cleaned and dressed, sitting at the island bar with a plate full of food in front of him.

“So Emily is on her way over here now?” he said.

“Yes, she’s nearly here. And she’s going to want to start talking about pregnancy.” Amy replied.

Jack could feel his stomach drop. He gulped. He wasn’t ready to be a father.

“Look, sweetheart, I know this is probably overwhelming. That’s why I wanted to talk through it together before she got here. How are you feeling?”

“Honestly,” he said, feeling like he was now going to vomit back up the toast he had been chewing on, “I feel like I might be sick.”

“That’s totally normal,” his mother assuaged him. “But just remember this is all still a few months away. We will have some time to get used to it all.”

He heard her, but he wasn’t sure if a few weeks or months would even make a difference. He was still a kid in so many ways – he couldn’t be a father! Well, he technically wouldn’t be, he figured, given that Fred would believe the child was his own. But still, Jack would know, and eventually one day their child would know, too. That was the part he couldn’t get over. He tried explaining it to his mom.

“Believe me, honey, I felt the same way before I got pregnant with your sister.”

“You did?” he asked.

She nodded, fussing with dishes in the sink.

“Your grandpa and I obviously had talked about it quite a bit, but when it finally came time to… to do it… I felt paralyzed at first. Once I got married, I just felt the urges take over. And it was one of the greatest experiences of my life.”

Jack chewed on this for a moment. Amy finished drying off a frying pan and placed it on the rack.

“So you think the same will happen to Emily?”

“Perhaps,” she said, ambivalent. “Maybe it will take some time. But eventually it will have to happen, you know?”

“I know,” he replied.

“And you will be ready when the time comes,” she continued, trying to cheer him up.

“How do you know that?” he asked.

Amy swung around the island and planted a kiss on his forehead.

“Just trust me, you will be. Besides, you’ve had a lot of practice with me and your aunt already.”

“Mom…” he groaned. “It sounds gross when you say it like that.”

She laughed, amusing only herself.

The door creaked open, interrupting their conversation.

“Hello?” a voice called out. It was Emily.

“Hi dear, we’re in the kitchen,” Amy called back.

Emily was dressed in a cute, white onesie that ended in a skirt around her thighs. Her dark hair was pulled up in a lazy bun, and she was wearing her glasses. She immediately held up her hand, displaying the expensive looking diamond on her finger.

“Oh my god, it’s beautiful!” their mother exclaimed.

“Ahhh! I can’t believe it!” Emily cried in unison.

They embraced, mother and daughter both overjoyed.

“What do you think of the ring, Jack?” Amy asked.

“It’s… er, really nice, Emily. Congratulations.”

He couldn’t stop thinking of poor Fred, clueless and deceived. It wasn’t that he even liked the guy much – to be honest, he had always been kind of a tool – but Jack’s inner conscience wouldn’t rest. It was one thing to be intimate with his sister… Fred never needed to know what strange and unorthodox practices their family got up to behind closed doors. But to put a baby inside of her… to get her pregnant and use genetic trickery to fool him into thinking it was his own offspring? It felt like crossing an ethical line that Jack wasn’t totally certain he was comfortable with. He knew the importance of their family’s legacy. He knew it was his responsibility to carry on their lineage. Still… it wasn’t sitting well with him.

Emily finally pulled away from their mom and hopped gleefully over to him still seated at the island bar. She hugged him and squealed.

“Jack, can you believe it?! I’m getting married!”

He laughed uncomfortably.

“Hah, I know… It’s crazy…”

“Why don’t you two go talk privately upstairs. I’ll leave you alone while I do some chores down here,” Amy spoke.

Emily looked at her, then back at her brother.

“Okay, thanks Mom!” she said. She was bursting with energy this morning, Jack noticed.

He stood, and she practically led him by the wrist up to her old bedroom.

Amy let out a deep exhalation as her children disappeared up the stairs.

It’s finally happening, she thought. The torch has been passed. My duty has been done. We live on for another generation.

But that wasn’t all she was feeling… no, something else was lurking there deep in her subconsciousness. A desire, an urging. A yearning for something… but what?

His seed, her mind answered. Let him breed you with his seed, Amy.

No, she couldn’t! What kind of asinine idea was that? Her job had been done. She had borne two children for her family. Sure, she had loved every minute of it… watching as her belly had grown swollen with the product of her secret affair… the feeling of her daddy emptying himself inside of her cunt every night for weeks on end…

Amy felt a flash of warmth all over her body and a tingling sensation near her thighs. She was sweating, even though it was cool inside the house.

Empty him, Amy…

Images of her son pumping his semen into her pussy flooded her mind. His strained face, his tensing muscles, his twitching cock buried deep inside of her…

She pictured her belly, round and full again with another child. She pictured Jack worshipping her swollen tits as they leaked milk, just like her father had.

I’m too old, she said, trying to calm herself. My window of opportunity has passed.

That had seemed to do the trick. The intrusive thoughts evaporated as quickly as they had appeared. Something told her it wouldn’t be the last time she’d have to contend with them, however.

Her concentration was broken as she heard something upstairs crash and thud on the ceiling. She ran up the stairs to see what had happened.

“Emily? Jack? Are you okay?!” she called out.

Amy didn’t wait for a response before opening the door to her daughter’s old bedroom. Before her was a sight that she had not totally expected. Emily was stark naked and straddled on top of her brother, whose pants were down around his ankles. Her round ass was colliding into his lap rapidly, up and down, up and down, while her son’s hands latched onto her wide hips and plump cheeks. He had one of her breasts in his mouth, sucking and tugging on it voraciously.

“Oh, huh?!” Emily moaned, halting all movement as she craned her neck backwards to assess their intruder.

“Mom!” Jack exclaimed, unsure if he should feel embarrassed or not.

“Sorry! Sorry!” Amy cried, not wanting to interrupt further. “I see you two are already getting a head start.”

Emily smirked.

“Something like that. Now – a little privacy, please?” she chided with a laugh.

“Certainly, certainly!” their mother replied, backing away briskly and swinging the door shut. The moaning and slapping noises commenced on the other side. Amy felt the hot flashes again sweeping across her body. She tried to will away the feelings once again, but this time they wouldn’t go.

She hurried to her room, stripping off all of her clothes as she turned the hot water on in the shower. Using her fingers, she rubbed her clit until her whole body convulsed with pleasure. She grabbed a breast and squeezed it roughly, pretending it was Jack. The warmth and the steam intensified every sensation. She imagined her son ravaging her again. She remembered the fervor with which he had fucked her every day while Phil had been away. The energy and vitality he had expended on her. The feeling of how wrong it was, how dangerous it had been for her to allow him to do that with her… but now as her fingers moved over her bud, she felt the intensity all at once again. She involuntarily moaned out his name. Her voice was soft and musical.

“Jack… Yes, sweetie…. Jack…!”

Outside of her bedroom, only the sound of running water could be heard. Further down the hall, two bodies continued smacking against each other at an urgent pace, yelps and yowls echoing throughout the house. Outside, the cool summer breeze whistled through the pines and the tall grass. All else was silent. The idyllic home stood majestic on its wooded acreage.
