Ben 10 Porn Story: Ben 10 and the New Alien – Chapter 11

Chapter 11

Gwen could hardly believe what was happening as she led her father into her room and over to her own bed as Jane led her uncle and grandfather to the other bed. It still seemed like a dream the way their parents had showed up in the middle of their orgy and then explained how she and Ben were really brother and sister instead of cousins and that Grandpa Max was their real father. And now, while Ben was taking their mothers into the master bedroom to fuck them and knock them up, here she and Jane were in her bedroom with her father, uncle, grandfather getting ready to fuck them in their own beds.

“So dad,” Gwen asked as she sat down on the edge of her bed and pulled her naked father down next to her, “how long have you been dreaming of this day?”

“That’s hard to say,” Gwen’s father said as he reached out to rub her swollen belly. “Ever since you were born I dreamed that the day would come when I’d be able to fuck you, but I never thought it would happen so soon. Or that I’d get so horny as I watched you walking around the house with your belly and tits swollen with Ben’s growing baby. And now that you know the truth and I finally have the chance to fuck you I can’t wait to get my cock in your pregnant little pussy.”

“That sounds good,” Gwen sighed as her father’s hand moved down to her dripping pussy and his fingers brushed past her twitching clit until he slipped two of them into her slit. “I’ve always wanted something like this to happen, but even after I started fucking Ben and Grandpa Max I never thought I’d ever have the chance to fuck my own father.”

“Well you have the chance now,” Gwen’s father said as he took his fingers from Gwen’s cunt licked them clean with obvious pleasure. “And so do I. Now scoot back on the bed and lets fuck like bunnies.”

“I like the way you think daddy,” Gwen said with a grin as she scooted back on the bed until her pussy was level with the edge of the bed.

“Good,” Gwen’s father said as he knelt between the red-heads knees and brought his lips up to his daughter’s drooling slit and started licking the combination of Ben’s cum and Gwen’s cunt juice.

“That feels so good, daddy,” Gwen moaned as a shiver ran up her spine. “Eat my cunny daddy, lick it clean before you fuck me.”

“You have such a juicy cunt Gwen,” her father said as he took his mouth away from her cunt and used one hand to play with her erect clit while the other one stroked her swollen belly. “I can’t wait to feel your tight little cunt wrapped around my cock. I just wish I could knock you up like Ben did.”

“So do I daddy,” Gwen sighed as she felt Ben’s baby move around in her stomach, “I hope you don’t mind if I let Ben knock me up again after this one since you can’t do it for me.”

“Honey, I don’t care how many babies Ben puts in you belly, as long as I get to fuck you too.” As he spoke Gwen’s father got to his feet and spread his daughter’s legs even further apart as he brought the tip of his cock up to the preteen’s drooling slit and ran it up and down her pussy lips, teasing her clit at the top of every stroke.

“Oh God daddy,” Gwen moaned, she could feel her father’s shaft running up and down her cunt and her body shivered as the sexual energy started building up around her baby. “If you get me any hotter I’m going to cum before you get your cock inside me.”

“Well we can’t have that,” Gwen’s father said as he gave her a broad smile and aimed the head of his prick right for her open cunt lips. He stepped into the stroke and he and his daughter both moaned with pleasure as the head of his cock split her pussy open and slid into her pregnant belly. “I just wish I that could be my baby growing in your belly,” Gwen’s father sighed as he ran his hand lovingly over her swollen belly, “I never thought I’d feel jealous of Ben until I found out that he’d knocked you up. At least I had time to get use to the idea that you were carrying his baby before you got back from your road trip.”

“You know daddy,” Gwen said as her father’s prick slid in and out of her wet hot cunt, “now that I know the family secret I wish this was your baby. But that’s impossible, so I’m glad Ben knocked me up first.”

“So am I sweetheart,” Gwen’s father said as he bent down to kiss the girl’s milk filled tits as he continued to slide his prick in and out of his preteen daughter’s slit, rotating his hips with every thrust so his brown pubic hair meshed with her red cunt fur. “When your mother was expecting you I use to help her by drinking the milk from her tits every morning and night. By the time you were born she was producing enough milk for both of us. Can I drink your milk too?”

“Sure dad,” Gwen said with a groan of pleasure as her father sucked the milk from her breasts while he slammed his cock in and out of her pussy with enough force to make his balls bounce off her ass. “You can do anything you want as long as you leave enough milk for the baby and keep fucking me.”

“Oh I’ll keep fucking you alright,” Gwen’s father said as he came up for air, “and I hope you keep on having babies so I can keep drinking your milk.”

“I don’t think that’s going to be a problem either,” Gwen groaned as her father’s hard thrusts pushed her closer and closer to her orgasm. “Ben and I were already planning on having another baby after this one, we were just trying to figure out how to keep you and his parents from figuring out who the father was, but I don’t think that’s going to be a problem anymore.”

“No problem at all,” Gwen’s father said with a laugh, “in fact your mother and I were talking with Ben’s parents about how hard it would be to talk the two of you into having more babies after this one. So you and Ben go ahead and have as many babies as you want.”

“Just try and stop us,” Gwen said with a laugh that ended in a scream of pleasure as her father pushed her over the edge and into her first orgasm.

With his daughter’s cunt squeezing his cock so hard it couldn’t move Gwen’s father left it buried deep in her swollen belly and leaned forward until he could catch one of the girl’s bobbing nipples between his lips and start sucking on it. As Gwen’s body stopped twitching and shivering from her orgasm he managed to get a small stream of milk flowing from her milk filled tits and into his thirsty mouth. “Nothing like mother’s milk fresh from the tit,” he said as he took his mouth away from Gwen’s nipple and gave his daughter a quick satisfied smile before he bent back down to catch her other nipple between his lips.

“Oh yeah,” Gwen sighed as her father sucked the milk from her heavy breasts. “I never thought it would feel this good to have the milk sucked out of my tits. But don’t forget to keep fucking me while you do it.”

“I won’t,” Gwen’s father promised as he took his mouth from her breast and licked the drop of milk that oozed from her nipple. “I was just waiting for your pussy to relax enough that I could start fucking you without blowing my load on the first stroke. After all, I want to give you at least two orgasms for every one of mine.”

“Thank you daddy,” Gwen said with a moan of pleasure as her father’s cock started sliding in and out of her pulsing slit again.

“No, thank you, Gwen,” her father said as he shifted to her other nipple and licked the milk that oozed out of that tit. “I’ve been waiting for this night for years, and I was always afraid it would never come.”

“Well you don’t have to worry about that any more,” Gwen said with a sigh of pleasure, “you can fuck me and sleep with me all you want – as long as Ben and I aren’t working on a new baby that is.”

“I guess I can live with that,” Gwen’s father said with a grin as his daughter slid into her bed and rolled over on her side. He slid into the bed next to her and snuggled up to her back until his half hard prick bumped up against the back of Gwen’s legs until she opened her thighs just wide enough that he was able to slip between her legs until the head of his cock popped between her pussy lips and wedged into her fuck hole.

“That feels good daddy,” Gwen said sleepily, “and I know I’ll have nice wet dreams with your cock inside my cunt while we sleep.”

“Not as good as the dreams I’m going to have,” Gwen’s father said with a yawn as he slipped his arms around his red-headed daughter to squeeze her milk filled tits while he petted her swollen belly. “Good night, Gwen.”

“Good night daddy,” Gwen said with a yawn of her own as she closed her eyes.

As Gwen led her father to her bed Jane led Max and Ben’s father toward her bed. “Now how are we going to do this?” the brunette asked as she sat down on the edge of her bed and reached out to grip a cock in each hand. “I wish I could fuck both of you at the same time.”

“Oh I think we can manage that,” Max said as he gave his son a wink.

“What do you have in mind,” Jane asked in a worried voice as she looked from one wide grin to the other.

“Did Gwen ever tell you what a fuck sandwich was?” Max asked as he removed his cock from Jane’s loose grip and sat down next to her on the edge of the bed.

“You can’t be serious,” Jane said as she looked from Max’s cock to the even larger cock of Ben’s father. “You expect me to take one of your cocks in my ass while I take the other one in my pussy?”

“Gwen does it,” Grandpa Max pointed out as he lifted the pregnant brunette up and set her down on his lap. She could feel the older man’s cockshaft between her ass cheeks while the head tickled the base of her slit. “And I know she likes it because back at Thanksgiving she was the one suggested doing it again.”

“Here son,” Max said as he tossed the tube of KY Jelly to Ben’s father, “lube us up. Make sure you get plenty of lube in Jane’s ass.”

“Sure thing dad,” Ben’s father said as he knelt down and pushed Jane’s legs apart so he could get to his father’s cock and the eleven year old’s butt. He stopped to admire the girl’s beautiful brown furred cunt.

“I can see why Ben likes you so much,” Ben’s father said as he ran a couple fingers along the girl’s drooling pussy lips and then put the slimy digits up to his mouth to lick them clean. “I just wish I’d been the one to knock you up – but of course that’s impossible.” He put some lube in his hand and started to coat Max’s prick with it, from where she sat in Max’s lap Jane looked down at Ben’s father and noticed that his brown hair was thinning out to the point that he had the start of a bald spot toward the back of his head.

“If you don’t mind my asking,” Ben’s father said in a casual voice as if it was an every day thing for him to lube a girl’s ass before he fucked her. “What do you think of my son?”

“Ben?” Jane said shakely as Ben’s father pushed the lube into her ass. “This may sound strange, but I never really thought about it until now. The truth is, I love him. That may sound strange since I’ve watched him fuck two other girls on an almost daily basis – and that’s not even counting the fact that he knocked both of them up. Actually, I kind of liked watching him do it – even when I knew he was trying to knock Keesha up when he popped her cherry. I guess I’d say I was a voyeur if I didn’t like to join in. Does that sound crazy?”

“In this family I think you fit right in,” Ben’s father said, “what do you think dad?”

“I think you’re right, son,” Max said as he rubbed the tip of his cock through the lube that oozed out of Jane’s ass. As Max ran his cock up and down Jane’s lubed ass Ben’s father knelt between the girl’s knees and sucked on her pussy. When Max felt Jane quiver with pleasure he put his mouth next to her ear and whispered, “Are you ready for the first part of the fuck sandwich.”

“Yes,” Jane groaned as Ben’s father pushed his tongue deep into her slit. “I’m ready for anything.”

“Here we go then,” Max said as he raised Jane’s ass up a few inches from his crotch and set the head of his cock against her butt hole. Jane’s whole body went stiff as Max’s cock entered her ass and Max held her there with the head of his cock just inside her opening as his son continued to eat her cunt. “Ready for some more?” Max asked when he felt Jane’s body relax a little in his grip.

“Yes,” Jane hissed through her teeth. “This feels so strange, it’s like I’m taking a shit in reverse. But I think I’m going to like it.”

“I hope so,” Max said as he eased another inch of his throbbing shaft into the girl’s butt. He paused again as Jane tensed in his hands but continued when she relaxed almost immediately. This time Jane slid all the way down his shaft until the whole thing was buried in her ass. “How does it feel?”

“Weird,” Jane said with a shake of her head, “it’s not the same as having a cock in my pussy, but it still feels good and sexy. I like it, not as much as a cock in my cunt, but I do like it.”

“Well,” Max pointed out with a soft laugh, “this is only part of a fuck sandwich. Are you ready for the rest of it?”

“Sure,” Jane said with a broad grin as she watched Ben’s father stand up between her thighs so that his hard cock bounced temptingly just a inch from her slit. Jane had to crane her neck to the side to watch as Ben’s father grasped his shaft in his hand and aimed it for her drooling pussy.

As Ben’s father slid slowly into her pregnant pussy he placed his hands on either side of her swollen belly and gave her a big grin. “So, Ben’s twins are in there, is that right.”

“Yes,” Jane said with a hiss as she felt the new cock slide past the one buried in her ass with just a thin wall of flesh between them.

“I am so jealous of my own son right now,” Ben’s father said as he slid the rest of his cock into Jane’s cunt and rotated his hips so that his pubic hair tickled the girl’s erect clit. “I wish I had three hot horny pregnant sluts to fuck, and that’s not even counting the two new ones he’s fucking right now.”

“But you do have three hot horny pregnant sluts to fuck,” Jane pointed out. “At least you would if Keesha was here to join in the fun. But don’t worry, I’m sure Gwen and I can make up for her.”

“I’m sure you will,” Ben’s father said as he started to slide his cock in and out of Jane’s tight cunt, slapping his flat belly against her swollen one with every stroke. Jane could feel Max starting to move in her ass too and she was surprised to realize just how fast her body responded to the double stimulation and jolts of sexual energy rushed up her spine from her ass and her pussy both.

“I’m cumming,” Jane screamed as the two cocks in her body sent bolts of energy straight to her brain as it exploded in pleasure.

“Hold on son,” Max yelled, “ride this one out and let’s see how many more we can give her before we explode.”

“I’m trying dad,” Ben’s father said through clenched teeth, “but her cunt’s milking me for all it’s worth.”

“You can do it,” Max encouraged as he tried not to shoot his own load into Jane’s ass.

Somehow the two men managed to hold on until Jane’s body stopped quivering and her pussy and ass released their pricks so they could keep fucking her. But both men knew that they wouldn’t be able to hold out through another orgasm and they were both determined to give Jane as much pleasure as they could before the pregnant preteen milked them dry.

“Oh God,” Jane gasped as the two men continued to fuck her ass and cunt, “this is better than I ever imagined it would be.”

“I knew you’d like it,” Max growled as he slammed his cock in and out of Jane’s ass.

“Like it?” Jane groaned, “I love it. This is better than straight fucking, and I love that.”

Ben’s father could feel his balls start to clench and he knew it wouldn’t be much longer before he shot his load deep in the belly of his son’s pregnant girlfriend. He looked down at Jane’s face and saw her gasping for breath as she approached her second orgasm, and from the look of concentration on his father’s face he knew Max would be shooting his load right along with him.

“Jane,” Ben’s father said with affection as he looked down at the girl’s bouncing tits and belly.

“Yes?” Jane managed to say as she panted for breath.

“Welcome to the family,” Ben’s father said as he buried his prick deep in the girl’s pregnant body and shot his load into her spasming cunt as Jane milked every drop of cum from his shaft and balls.

“Oh God,” Max screamed as he shot his own load deep into Jane’s bowels and her ass clamped tight around his shaft.

“Thank you,” Jane murmured as she hugged Ben’s father and leaned forward to kiss him. “This is the best welcome I could ever hope for.”

“And it won’t be the last one,” Ben’s father said as Jane’s pussy held his cock tight. “But it may be the last one for now, that cum drained me more than I expected.”

“Me too,” Jane said with a yawn as she released Max’s cock from her ass and pulled Ben’s father onto the bed next to her. “Why don’t we sleep like this, and if you wake up during the night with enough energy to fuck me again, go for it.”

“Oh, I will,” Ben’s father promised. “Dad, why don’t you turn off the light? It looks like Gwen and her father are already asleep.”

“Ok,” Max said as he got off the bed, “but make some room for me too.”

“Sure thing,” Jane murmured sleepily as she shifted her body to make room for the older man.

With a satisfied smile Max turned out the light and slid into the bed, his cock nestled up against Jane’s ass.

* * * *

As he followed his mother’s naked ass into the master bedroom Ben was still trying to make sense of everything that had happened that night. It was still hard to believe that he and Gwen were actually brother and sister and that Grandpa Max was their real father. It was even harder to believe that their parents had planed for them to end up fucking each other – much less that his mother and aunt expected him to knock them up with his own brothers and sisters. But here he was following his naked mother into his aunt and uncle’s bedroom with his naked aunt following them through the door.

“So Ben,” his mother said as she turned around and sat down on the edge of the bed as his aunt sat down next to her and opened her thighs to give him a clear view of her dripping slit. “Are you surprised?”

“Fuck yes,” Ben said as he forced his eyes away from his aunt’s hot pussy and found himself staring at his mother’s tits instead. “Gwen and I never suspected a thing.”

“Good,” his mother said as she ran her fingers down her breasts and stomach until the came to rest on her erect clit, “does it bother you to find out that you fucked your own sister and knocked her up?”

“No,” Ben said slowly as he watched his mother and aunt stroking their pussies as they watched him.

“What do you think about fucking the two of us and knocking us up?” Gwen’s mother asked as she licked her lips in anticipation.

“I think I’m going to be one happy, horny, mother fucker – and aunt fucker for that matter.”

“Good,” Ben’s mother said with a pleased smile as she reached out to run her finger along Ben’s cock. “So, who are you going to fuck first?”

“Well,” Ben said slowly. considering his words carefully as he looked from his aunt’s red hair and bobbing pink nipples before he turned to look at his mother’s brown hair and full tits. “It’s real hard to decide between two hot and horny women – especially since I know that you’re both fertile and that I’ll be able to knock both of you up before the nights over.”

“Well both of us are in our fertile periods,” Ben’s mother said as she reached down to stroke her son’s hard cock. “But you still have to decide which one of us you’re going to fuck first.”

“I know,” Ben said as he reached out to pinch his mother’s hard nipples.

“Don’t forget me,” Ben’s Aunt Karen said with a laugh as she ran her fingers down her nephew’s stomach until she reached his balls and ran her fingers through Ben’s pubic hair.

“How can I forget about you when you keep waving your big tits right in front of my nose?” Ben asked as he reached out with one hand to squeeze the red-head’s full tits. “But right now I think I should fuck my mom first. After all, I have to live with her.”

“You’ve got that right young man,” Ben’s mother said with mock sternness as she lay back on the bed and opened her legs in obvious invitation as she gave her son a wide grin.

“You do have a point,” Ben’s aunt admitted as she shifted to the head of the bed so she could easily reach the other woman’s large tits as Ben crawled between his mother’s open legs.

“Wow,” Ben said as he looked down at his mother’s hairy cunt, “I didn’t know a pussy could have so much hair. When I started fucking Gwen she only had a few red hairs around her slit, and even Jane only had enough hair to see the color of her pubic hair.”

“Well Gwen and Jane are still pretty young,” Ben’s mother pointed out as her son ran his fingers through her thick thatch of wet pussy hair. “Your aunt and I are grown women so we have a lot more hair down there.”

“I guess so,” Ben said as he used his fingers to push the pubic hair away from his mother’s slit and then leaned forward to kiss her cunt before he stuck his tongue out and ran the tip up and down her swollen pussy lips and sucked on her clit.

“Oh yes,” Ben’s mother moaned as her eleven year old son ate her pussy like he knew exactly what she was doing. “How many girls have you done this to, Ben?”

“Just Gwen, Jane, and Keesha,” Ben said quickly as he pulled his tongue away from his mother’s slit and gave her and his aunt a defensive smile.

“Don’t give me that Ben,” Ben’s mother said as she ran her hands through her son’s brown hair. “It’s obvious that you have more experience eating pussy than you could get with just three girls.”

“Your mother’s right Ben,” Ben’s aunt said as she massaged his mother’s breasts. “Just watching you I can tell that you have a lot more experience than you could get from eating out three girls. I promise I won’t tell Gwen, but just how many girls are you fucking right now?”

“Counting Gwen, Jane, and Keesha I’m up to a half-dozen right now,” Ben admitted sheepishly, “and by this time next week I’ll probably be up to a dozen – and that’s without counting the two of you.”

“In that case you should be able to give both of us several orgasms each before the night’s over,” Ben’s mother said as she pushed her son’s head back into her crotch so he could go back to eating her wet cunt.

“And you should be able to knock us both up too,” Aunt Karen said as she squeezed Ben’s mother’s tits so her nipples popped out so she could lean down to lick her friend’s tits.

“I’m sure I will,” Ben said, his voice muffled by his mother’s cunt.

Realizing that he no longer had to hide his experience at pussy eating Ben started using all the tricks he’d learned while eating and fucking the girl’s he’d already knocked up at school. Just like with Keesha Ben knew that his mother and aunt were both fertile and he knew that if he fucked both of them during the night he’d knock both of them up before the whole family met in the living room in the morning.

“Yes,” Ben’s mother screamed as her son’s tongue drove her over the edge. Ben sucked at his mother’s slit, drinking the juices that flowed from her spasming cunt as fast as he could, but it wasn’t fast enough amd his face was smeared with much of the juice that spurted out of her cunt lips.

“I guess you liked that,” Ben said as he took his face out of his mother’s pussy and smiled at her over her large tits.

“I loved it,” Ben’s mother said as she smiled down at her son. “And I’m going to love it even more when you start fucking me.”

“Why wait?” Ben asked as slid up his mother’s body, kissing her flat belly and full tits as he brought his cock up between her thighs until the tip kissed her soaked pussy.

“Yes,” his mother said as she grabbed her son’s shaft in her hand and held it steady against her slippery cunt lips. “Fuck me Ben, fuck me and knock me up with your baby.”

“Yes mother,” Ben said, giving his mother another smile before he bent down to kiss her as he slid his cock into her hot wet pussy. “I promise to do everything you want me to, you know how obedient I am when I want to be, and right now I really want to obey you.”

“Good boy,” Ben’s mother said with a sigh of pleasure as her son’s cock entered her body with one quick thrust. “Now fuck me hard and fill my belly with your baby.”

“With pleasure,” Ben said, giving his mother another smile before he caught her large nipple in his mouth and sucked on it as he slammed the full length of his cock into his mother’s cunt with all his strength.”

“Fuck me Ben, fuck me,” Ben’s mother screamed as her son fucked her enthusiastically. “You are such a good fuck Ben.”

“I love to fuck mom,” Ben grunted as he arched his back and watched his mother’s tits bouncing with every thrust. “And I really love fucking you. Why did you wait so long to tell us the truth? I could have been fucking you and Aunt Karen for months now if you’d just asked me to do it.”

“I’ve been wondering about that for almost four months now,” Aunt Karen said as she slid into the bed and reached for one of the tits bobbing in her face. “But everyone else wanted to wait until we found out if you were ready and willing to fuck anyone besides Gwen.”

“Ready, willing, and anxious to knock up as many girls as I can,” Ben said as he continued to fuck his mother. He could feel his balls starting to twitch and he knew it wouldn’t be long before he shot his load and knocked his mother up with his own brother or sister. He could tell his mother wasn’t far behind him as her cunt twitched around his shaft in anticipation of her second orgasm of the night.

“Good,” Ben’s mother panted as she wrapped her legs around her son’s ass and pulled her in tight as his cock jumped in her pussy and her fuck hole clamped tight around Ben’s shaft and held it deep in her belly as he shot his load with a scream of pleasure.

“That was wonderful mom,” Ben said as he leaned down to kiss her sweaty face without removing his cock from her sucking pussy.

“So, what are the chances that you knocked me up?” Ben’s mother asked with a sigh as she caught her breath.

“Excellent,” Ben said as he looked down at his mother’s belly, he could already see it swelling with the baby he knew he’d already managed to plant in her body.

“My turn,” Aunt Karen said, pushing Ben’s butt as his mother opened her legs so Karen could roll her nephew over onto his back. Ben noticed that his mother closed her legs tight together to hold his cum in her pussy and wondered if he should tell her that she didn’t need to do it, but he decided not to when he saw the look of pleasure on her face.

“You’re almost hard enough to fuck already,” Aunt Karen said as Ben’s back landed on the mattress and she grabbed his still erect cock in her hands. “A few quick licks and you’ll be ready to slide this baby maker into my cunt and knock me up too.”

“Oh God Aunt Karen,” Ben groaned as his red haired aunt sucked his shaft into her mouth and let it slide along her tongue. “You’re even better than Gwen.”

“Well my little girl doesn’t have my experience with cock sucking,” Aunt Karen said with a grin as she let Ben’s cock pop out of her mouth so she could lick the juice off her lips. “But now that you all know the truth I guess I can give her a few lessons. But as much as I love sucking cock, I love fucking even more – especially when I know the boy fucking me is going to knock me up. Are you ready Ben?”

“Ready, willing, and able,” Ben told his aunt as she straddled his hips and lowered her crotch until the red hairs around her slit tickled the tip of his quivering penis.

“Good,” Aunt Karen said, dropping her hips down on her nephew without warning so that his cock split her pussy lips and slid all the way into her fuck hole until her erect clit rested on Ben’s bare belly. “Oh God I love fresh cock,” Ben’s aunt moaned as she swivelled her cunt in a circular motion around the eleven year old’s buried cock.

“Not as much as I love fresh pussy,” Ben groaned as he reached up to grab his aunt’s swaying tits and pulled her down so he could suck on her erect nipples.

“Good boy, Ben,” Aunt Karen said as her nephew sucked on her tits and she started sliding her slit up and down his pole. “Even if I didn’t know about Gwen and the other girls I’d know that you’d fucked before. You obviously know what you’re doing.”

“But I still have a lot to learn,” Ben said with a groan of pleasure as he took his mouth away from his aunt’s nipples. “Are you ready to teach me Aunt Karen?”

“Ready, willing, and able,” Ben’s aunt said, repeating his own words with a chuckle.

“We’ll both teach you, Ben,” his mother said as she leaned over to give her son a kiss. “But right now I think you’re doing just fine. In fact I think you’re right about knocking me up already, even if it will take two or more weeks to get morning sickness and a positive result on a pregnancy test. So, do you want a sister to fuck? Or a brother to help you keep up with all the daughters you have to fuck when they get old enough?”

“I don’t know, mom,” Ben panted, he could already feel his balls starting to fill with a fresh load of cum and he knew it wouldn’t be long before he was knocking his aunt up just like his mother. “How would you like to have both?”

“Twins?” Ben’s mother said thoughtfully, “I don’t know if I’m ready for that.”

“Who said anything about twins?” Ben panted as his aunt picked up the pace of her fucking, he could feel her fuck hole quivering around his cock and he knew it wouldn’t be much longer before she had her orgasm. He hoped he’d be able to hold off until she made it. “I just thought we’d have a few more after this one until I had enough brothers and sisters to keep me busy for the rest of my life.”

“I like the way you think Ben,” Aunt Karen said as she pulled her tits out of Ben’s grasp and rode his cock so hard he thought she was going to bounce right off it. Somehow the older woman managed to keep the head of his prick in her fuck hole in spite of her enthusiasm and rode it all the way down to his balls with every stroke. Suddenly Aunt Karen’s head snapped back as she drove her pussy down for one last thrust and held it there as her cunt muscles squeezed his shaft like a vice and she screamed in pleasure as her red hair was flung back and forth with every shake of her head. “I’m cumming,” she screamed.

“So am I,” Ben screamed a second later as his balls clamped tight and he shot the first wad of cum into his aunt’s thirsty womb. “Here cums your baby Aunt Karen.”

“Yes,” Aunt Karen screamed as her body thrashed around in pleasure, her pussy, clamped tight around her nephews spewing cock was the only thing that didn’t seem to be moving.

“Oh my God,” Ben’s aunt said a few minutes later as she rolled off her nephew, her body still quivering from the intensity of her orgasm. “Are you sure you knocked me up?” she asked.

“I’m sure,” Ben said as he looked up and down his aunt’s naked body. He still didn’t know how he knew, but he was sure he’d managed to knock up both his mother and aunt now.

“How are you doing Ben?” his mother asked as she slid her hand down his body until she was able to grasp his wilted cock. “Think you can go another round just to be sure?”

“I’m already sure, mom,” Ben said with a weak grin, “but even if I wasn’t I need to rest before I’m ready for another round.”

“Ok Ben,” his mother said as she snuggled up next to him on one side and his aunt snuggled up on the other, “but remember, if you wake up during the night and you feel horny enough to go again, we don’t mind.”

“I’ll remember that,” Ben said with a yawn as his mother turned off the bedside light and he closed his eyes to sleep, dreaming of the next day and all the fucking he’d be able to do then.”
