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

Chapter 10

“But mom,” Ben whined as he faced his brown haired mother in the kitchen.

“Don’t you ‘but’ me Benjamin Tennyson,” Ben’s mother said in a tone that meant business. “Your father and I are going to his company Christmas party tonight and you’re just too young to be left home alone. Normally we’d get you a baby sitter but it’s too late to get one now so you’ll just have to go to your aunt and uncle’s house for the night.”

“Yes ma’am,” Ben said as he turned his eyes toward the floor so his mother wouldn’t see the gleam in his eyes as he thought about seeing Gwen.

“Now your aunt and uncle are going to be gone for their own party tonight,” Ben’s mother continued when Ben didn’t say anything more, “but your Grandpa Max will be there so make sure you do everything he tells you, is that clear?”

“Yes ma’am,” Ben said as he hid his smile at the thought of seeing Grandpa Max for the first time since Thanksgiving.

“And one more thing,” Ben’s mother added, “Gwen’s friend Jane just moved in because her parents didn’t want her staying in their house because of her pregnancy. Now I don’t want you teasing Gwen or Jane because of their pregnancies, do I make myself clear.”

“Mom I’m not going to tease either of them because of their pregnancies,” Ben promised. “I like Jane, and Gwen isn’t nearly the geek she was before she got knocked up. I promise I won’t tease them, ok?”

“Very well,” Ben’s mother said as she eyed her eleven year old son suspiciously. “But I expect you to keep that promise.”

“I will,” Ben said as he got his features under control and looked his mother in the eye as he spoke.

“Ok,” Ben’s mother said in satisfaction, “now you better head over there right now so you can be there before your aunt and uncle leave for their party.”

“But mom, that’s what I’ve was trying to tell you,” Ben said. “I need to stop and Keesha’s house on the way. She called in sick today and our Biology teacher asked me to drop off her final exam. Since it’s on the way I thought I’d drop it off on the way.”

“Very well,” Ben’s mother said with a nod after a seconds thought. “But don’t take any longer than you need to to drop off the exam, is that clear.”

“Yes mother,” Ben said as he grabbed his jacket from the chair he’d thrown it on when he got home a few minutes earlier. “I’ll get there as fast as I can.”

Ben was out the door and headed down the street before his mother had a chance to say anything else. As soon as he reached the street Ben turned north and headed for Keesha’s house, he’d never actually been there but Keesha had told him where she lived and he had a good idea of where to go and her address when he got close enough. A few minutes later Ben found himself licking his lips as the approached the door of the beige house with brown trim that had the street address Keesha had given him.

After ringing the bell Ben waited nervously until he the door opened a couple inches and he saw an eye looking at him through the crack. “Yes?” a voice called through the opening.

“Hi,” Ben said to the female voice on the other side of the door, “I’m Keesha’s lab partner Ben Tennyson. Since Keesha was out sick today I offered to drop off her final exam.”

“So you’re Ben,” the tall black woman said a few seconds later as she opened the front door wide enough to let Ben enter the house. “Keesha told me about you, but I guess she didn’t tell me everything. She had a touch of stomach flu this morning so I made her stay home. I figured nothing important would be happening at school today so it wouldn’t hurt to keep her out for today. If you want you can run up to her room and see her for a minute, but only for a minute.”

“Thanks,” Ben said as he headed to the stairs Keesha’s mother pointed out, “I only have a minute because I have to get to my aunt and uncle’s place before they leave for their company party.”

As Ben rushed up the stairs he took a quick glance back to see what Keesha’s mother was doing as he headed for her room. Ben reached the open door leading to Keesha’s bedroom and knocked on the doorframe before he entered. “Ben,” Keesha said with a broad smile when she saw him walk through her door.

Keesha craned her neck to look past Ben and he gave her a smile of his own as he said, “Don’t worry, I saw your mom head for the kitchen after she told me where to find your room.”

“Good,” Keesha said as she fell back into the pillows supporting her head. “Did she tell you I had a touch of stomach flu this morning?”

“Yes she did,” Ben said, “but from the way you’re acting I suspect that she hasn’t guessed the truth yet.”

“You’re right,” Keesha said with a giggle, “mom walked into the bathroom when I was throwing up in the toilet bowl, but I was able to hide this before she noticed it.” Ben glanced at the stick from the pregnancy test and gave the black haired girl a quick smile when he saw the plus sign in the small window. “And before you ask it took the full time for the response to show up so I don’t think I’ll find myself in Jane’s situation. Just a single baby growing in my belly.”

“In that case I guess I have even more good news for you, “ Ben said as he handed over her Biology exam.

“A B+?” Keesha said in shock as she looked at the mark on the first page, “how did you do?”

“I got an A-, “ Ben said with an embarrassed grin, “that gave me a B- for the semester and it gave you a straight B.”

“How did you end up with a higher grade than I did on the final exam?” Keesha asked with a shake of her head. “You struggled through the whole semester.”

“Right up until the end,” Ben said with a nod, “but once I got interested in the subject I threw everything I had into improving my grade during the last marking period. Now I can’t wait to learn more – especially about genetics.”

“Good,” Keesha said, “I guess that means we can be lab partners next semester too then?”

“You’ve got that right,” Ben said. “Sorry to trade good news and run but I have to get to Gwen’s, our Grandpa Max is babysitting us while our parents attend their company Christmas parties. Since Jane’s staying at the house now it could be a very interesting night.”

“I wish I could join you,” Keesha sighed, “but even if mom didn’t think I was sick she’d never let me go. You go ahead and enjoy your little party, and feel free to let Jane and Gwen know the good news.”

“I will,” Ben said as he turned to leave.

“And Ben,” she called before the younger boy had a chance to leave, “how are Angie, Sue, and Tracy doing?”

“How did you know about them?” Ben asked in surprise as he turned back to look at the smiling Keesha.

“Sue’s an old friend of mine,” Keesha explained, “and you didn’t exactly hide things between the three of them. So, how are they doing?”

“Tracy’s a week late and Sue’s a day late,” Ben said with a frown, “but it’s too early to be sure if they’re pregnant. I only popped Angie’s cherry last week but it was her most fertile time so I think there’s a good chance that she caught too, but it’s just too early to know.”

“It may be early,” Keesha said with a smile, “but I think congratulations will be in order where you and those three girls are concerned. Don’t worry, I won’t tell anyone about your three new conquests, but try to keep your libido under control, ok?”

“I’ll try,” Ben said as he thought about the two girls he was planing to fuck after Christmas break. “Say Keesha, what are your parents going to say when they find out you’re pregnant?”

“Well, there’s only my mom,” Keesha said as she chewed her bottom lip thoughtfully, “and I don’t think she’s going to give me too much trouble when she finds out about the baby, or didn’t you notice that she’s only 26? By the time the baby is born I’ll be a year older than mom was when I was born so she can’t have that much to say about it.”

“I’m glad to hear that,” Ben said with a relieved sigh. “And now I really need to get moving – in fact I think I better change into XLR8 if I’m going to get to Gwen’s before I’m really late.”

“Ok, see you at the usual place and time in two weeks?”

“You bet,” Ben said with a broad grin, “I can’t wait.”

As Ben said goodbye to Keesha’s mother at the door he took a closer look at her and realized that she really was in her mid-twenties, he also sensed that the woman was in the middle of her fertile cycle. Ben forced himself to ignore what his senses were telling him about Keesha’s mother and thanked her as she closed the door behind him. As he walked down the street toward his aunt and uncles house Ben looked around to make sure the street was empty before he raised the Omnitrix and dialed up XLR8’s outline before he hit the plunger. Seconds later Ben was speeding along in his lizard like form, his green and black afterimage fading behind him even as he came to a stop just outside Gwen’s home. Since the Omnitrix hadn’t timed out yet Ben took a few laps around the block until he saw his watch flashing red and came to a stop at the end of sidewalk just as it timed out.

“I’ll get it,” Gwen called as she trotted to the front door.

“Gwen,” her mother called as poked her head around the corner, “you’re still in your robe. Don’t answer the door to a stranger dressed like that.”

“It’s just Ben,” Gwen said as she peered through the spyhole in the door. “He’s seen me in a lot less than my robe.”

“What?” Gwen’s mother said, her mouth gaping in surprise.

“Mother,” Gwen said unlocked the door. “We did go swimming during the summer you know.”

“That’s true,” Gwen’s mother said with a relieved sigh as she returned to the other room. “Just as long as he doesn’t see you in anything less than you bathing suit.”

The last sentence was said soft enough that Gwen was able to ignore it as she opened the door to Ben’s smiling face. “Hi Ben,” Gwen said as she took a quick glance around to make sure no one else could see them. Once she was sure Gwen opened the front of her robe so Ben could see what she was wearing under it as she continued, “mom and dad are just getting ready to leave.”

“Gwen,” Ben hissed as he looked at the familiar blue on blue t-shirt the redhead was wearing, “is that?”

“The same shirt I was wearing when you popped my cherry and knocked me up,” Gwen confirmed with a quick nod as she rubbed her swollen belly where the too small shirt left it bare. “I thought you’d like seeing it again – and it looks like I was right.”

As Ben struggled to get his erection under control Gwen wrapped her robe back around her body and tied the belt around her pregnant belly. “The four of us are going to have so much fun after my parents leave,” Gwen whispered to her cousin as she led him into the room where her parents were getting ready to leave.

“Thanks for letting me stay here while you’re off to your party Uncle Jim, Aunt Karen,” Ben said politely as he held his aunt’s jacket so she could slide her arms into the sleeves.

“Well it was the least we could do since we already borrowed your Grandpa Max to babysit Gwen and Jane,” Uncle Jim said as he pulled his keys from his pocket and swirled them around on his finger. “Speaking of your grandfather, he should be here any minute. We expect the three of you to be on your best behavior both before and after he arrives, is that clear?”

“Yes sir,” Ben, Gwen, and Jane responded quickly, doing their best to hide the smiles that threatened to cross their faces.

“Your grandfather is picking up dinner on his way here so you should have plenty to eat,” Aunt Karen said as she fastened her coat.

“Oh no,” Ben and Gwen groaned together.

“Don’t worry,” Karen said with a short laugh, “he’s just grabbing a couple pizzas, we don’t expect you to eat any of the health food he enjoys so much.”

“Thanks mom,” Gwen said with a relieved sigh.

“Yeah, thanks Mrs. Tennyson,” Jane said with a sigh of her own as she patted the swollen belly under her oversize shirt. “I wasn’t looking forward to experimenting with a grub casserole or anything like that. Ben and Gwen told me about some of the meals they had with their grandfather during their road trip.”

“Well you don’t have to worry about that tonight,” Uncle Jim said. “It’s just two large pizzas with everything and a side order of bread sticks. We’ll see you when we get back, but don’t expect us until late. Ben, are you staying for the night or are your parents going to pick you up after their party?”

“That hasn’t been decided yet,” Ben said as he swung his backpack off his shoulder, but just in case I brought something to wear to bed, and a change of clothes for the morning.”

“Good enough,” Uncle Jim said as he flipped his keys up one more time and snatched them out of the air. “We’ll see you later then.”

Ben let out a sigh as the door closed and locked behind Gwen’s parents and turned to give the two girls a broad smile. “I was beginning to think those two would never leave. So, what are our plans for the night?”

“First we wait for Grandpa Max to get here with dinner,” Gwen said as if she were reciting a schedule to a child, “then we have dinner, then we fuck like bunnies.”

“Do we have to wait for grandpa?” Ben grumbled, “I’m ready to fuck now – especially after getting the news from Keesha.”

“You saw Keesha?” Jane asked excitedly. “I knew she was sick today and that’s why she didn’t show up for our fuck sessions, but how is she?”

“Pregnant,” Ben said with a self-satisfied grin. “Her mother walked in on her while she was having a bout of morning sickness and assumed she had the stomach flu, but she managed to hide the pregnancy test and showed me the result when I stopped on the way here. But I’m ready to fuck, and it looks like Gwen is with that old shirt she has on under her robe.”

“Ben, it wouldn’t be fair to start before Grandpa Max gets here,” Gwen pointed out. “Besides, my pregnant pussy may be hungry for your cock, but stomach is even hungrier for that pizza grandpa’s bringing.”

“I have to agree with Gwen,” Jane said with a shake of her brown hair when Ben turned to her for support. “I’m hungry, and I think I should have a chance to know your grandpa a little better before I end up fucking him.”

“Ok,” Ben groaned, “I know when I’m outnumbered. But I expect the two of you to fuck like crazy after we finish eating.”

“I don’t think that will be a problem, Ben,” Gwen said with a broad grin.

All three of them turned when they heard the front door open and Gwen tugged at the belt of her robe to make sure it was tight around her engorged belly as Grandpa Max opened the door and stepped into the living room with two large pizza boxes balanced in his free hand as he shut the door behind himself. “Who’s ready for dinner,” he called as he looked at the three faces turned up to look at his Hawaiian shirt behind the pizzas.

“I am,” Gwen said as she jumped forward to take the top box from her grandfather. “Why don’t we take the pizzas to the kitchen and eat there? No reason to be formal and eat in the dining room, besides, too many people can see us through the dining room windows.”

“That’s true,” Grandpa Max said as he and the others followed the red-head into the kitchen. “And it sounds like you have an idea for something that we might want a little privacy for.”

“Just a little idea,” Gwen said with a grin as she set the pizza box down on the table and went to the cupboard for some paper plates and towels. “In case you haven’t guised already grandpa, this is our friend Jane. Ben knocked her up with twins our second day in school and now that she’s showing her parents don’t want her staying in their house so she’s staying here with me now.”

“And whose idea was that?” Grandpa Max asked as he gave Jane an appreciative look from her bare feet to her already swelling tits before he forced his eyes a little higher to look at the girl’s face. “Was it yours or your parents?”

“I suggested it,” Gwen said with a grin, “but once I told mom and dad what Jane’s parents were doing I didn’t have to work on them too hard before they made the offer to take her in until her babies were born. Of course they don’t know that Ben is the father – or how we’ve been spending our evenings since she moved in.”

“I see,” Max said as he ran his hand across his short grey hair, “and just what have you been doing in the privacy of your room?”

“Let’s just say,” Jane said with a grin, “that I never knew how good it felt for two pussies to rub together. On top of that we would have spent a fortune replacing batteries in our dildos if Ben hadn’t improved them with eternal batteries.”

“I wish I could have been there,” Grandpa Max sighed.

“Well you will be tonight,” Gwen pointed out with a broad grin, “you and Ben both. And to start things out I thought we’d get to know each other a bit better by eating dinner in the nude. What do you think of that idea?”

“I think it sounds great,” Max said as he watched Gwen remove her robe and toss it off to the side. Even as Gwen reached for the tight fitting blue on blue t-shirt with the cat face cartoon he reached for the buttons of his Hawaiian shirt and tossed it on top of Gwen’s discarded robe and Ben and Jane weren’t too far behind them.

As the four naked diners watched each other Ben realized that while his eyes continued to drift toward Gwen and her swollen belly and tits, his grandfather’s gaze stayed on Jane’s even larger tits as they ate. “So, Jane,” Grandpa Max said as he grabbed his third slice of pizza from the box, leaning forward to get a good look at the girl’s tits and swollen belly before he sat back in his seat. “Did Ben really put two babies in that belly of yours?”

“He sure did,” Jane said with a wide grin as she pushed her brown hair back from her face and set her shoulders back so Max could get an even better look at her breasts. “But now that I’ve met you I almost wish that I’d waited.”

“Really?” Max asked as he puffed his chest out proudly.

“Almost,” Jane said with a wink as Ben and Gwen snickered. “Now that I’ve met you I realize that you have a larger cock than Ben and I realize how much I want to feel it inside me, but I was just too horny to wait for you. And once Ben slid into my pussy and filled it with his cum that was all my body needed to start swelling up. I’m happy to have Ben’s babies growing in my belly, but I do look forward to the feel of your cock slamming in and out of my hot cunt.”

“Such a hot dirty mouth on such a young girl,” Grandpa Max chuckled, “it makes me so hot I want to slide my prick into your slit right now.”

“Gwen told me you liked it when she talked dirty,” Jane said with a grin, “and that’s just the response I was hoping for. And who says we have to wait? My stomach’s had enough food for now, and now it’s hungry for something else.”

“Maybe we should move somewhere where we’ll be more comfortable,” Max said as he slid his chair back from the table and reached a hand out to help Jane get up from her own chair. “Why don’t we move into the den?”

“We haven’t fucked in there yet,” Ben said with a smile as he helped his red-haired cousin to get up from her chair and the pair of them followed Max and Jane into the other room. “Do you two want the couch? Or would you prefer the floor?”

“What do you think Jane?” Grandpa Max asked the pregnant brown haired girl as the four of them walked into the den.

“If we fuck on the couch,” Jane said thoughtfully, “then we’ll have a clear view of Ben and Gwen while their fucking, I think I’d like that.”

“So would I,” Max said with a chuckle as he guided the pregnant eleven year old to the couch. Jane stretched out on her belly and raised her ass toward the ceiling as Grandpa Max sat down behind her and lowered his mouth to her juicy pussy and started teasing her slit and clit with his lips and tongue.

As Max continued to eat Jane’s dripping cunt Ben stretched his back out on the rug and helped Gwen as his red headed cousin straddled his hips while she faced the couch so Jane and her grandfather could clearly see her tits, belly, and cunt as she rode Ben’s prick. Gwen was so horny by now that Ben didn’t even have to tease her pussy to get her juices running. Even as she lowered herself on her cousin’s hard cock she could feel her erect clit rubbing along the shaft and sighed with pleasure as she watched her grandfather get up on his knees behind her best friend and fit the head of his cock against the other girl’s pussy.

“Fuck her grandpa,” Gwen gasped as she raised and lowered her pregnant body on Ben’s cock.

“Fuck him Gwen,” Jane moaned as she watched the red-head bounce up and down on her cousin’s erect cock with enough force to make her swollen belly and tits jump with every stroke. She could feel Max’s cock filling her pussy like it had never been filled before, even in his alien forms Ben was smaller than his grandfather – not by much, but enough to make a difference when the person fucking you knows how to use his prick. With every stroke Max shifted his prick so it rubbed against a different spot in the walls of her fuck tunnel and sent a new jolt of sexual energy racing up her spine. As her pussy lips started to quiver with her approaching orgasm she felt Max’s finger stroke her erect clit to send one last bolt of sexual energy running across the babies growing in her swollen belly and up to her brain as her whole body went rigid and she screamed loud enough to fill the whole house with her pleasure.

“I’m cumming,” Grandpa Max panted as Jane’s pussy gripped his prick in a vise and milked the baby juice straight from his balls.

Ben watched as Grandpa Max’s body jerked and shook from his orgasm and Jane collapsed under the older man to look at him and Gwen and smile as the two cousin’s continued to fuck. “Was that hot or what?” Ben asked Gwen as the red head continued to ride his cock. He could feel her pussy quivering around his shaft and he reached around her body to run one hand across her pregnant belly as he reached up to squeeze her swollen tits.

“It’s hotter than hot,” Gwen gasped as she looked down at the tit Ben was squeezing. She thought she saw a drop of milk oozing from the nipple but her tits were bouncing so hard with every stroke she wasn’t sure if it was actually there before it slid down her breast. With every stroke Gwen clamped her fuck hole around Ben’s invading prick and she could feel it starting to jerk around in her belly as his swollen balls bounced off her clit.

“I’m cumming,” Ben screamed as his balls squeezed the juice through his penis and deep into Gwen’s body as he grabbed his cousin around the waist and pulled her tight against his crotch as he gave their baby a cum bath.

“I’m cumming too,” Gwen shouted as she wrapped her arms around her quivering belly as she felt Ben shoot his load into her. Her whole body jerked and spasmed with every wad of baby juice her cousin shot into her body and once she was done she fell to her side with a groan as Ben’s cock popped out of her vibrating slit.

“Don’t tell me you’re tired already,” Grandpa Max said with a chuckle as Gwen lay on her side and tried to catch her breath after her orgasm. “The nights just starting and I for one want to get in as much fucking as possible.”

“So do I,” Gwen groaned, “but I still need time to recover after an orgasm like that – especially since I’m almost seven months pregnant.”

“I don’t know about that,” came a feminine voice from the door, “when I was seven months pregnant I was so horny I thought I’d never get enough cock.”

“Mom,” Gwen screamed in horror as she raised her head from the floor so she could look at the four people standing in the doorway to the den.

“Don’t worry honey,” Gwen’s mother said with a grin as she crossed the floor and knelt down by her daughter and nephew. “We’ve known the truth from the beginning. We knew all about you and Ben and your grandfather. We even knew about Jane and how Ben managed to knock her up with twins. We know about Keesha too.”

“But how,” Ben asked, watching his aunt in disbelief as she spoke, he didn’t even realize that his own mother had entered the room until he felt her hand wrap around his cock. Even as he turned to look his mother leaned forward to run her tongue along the length of his slimy prick as it started to grow hard in her grasp.

“How else?” Gwen’s father said as he and Ben’s father crossed the room, he knelt down by his red-headed daughter and reached out to squeeze the girl’s milk filled tit as he gave her a reassuring smile. “Your grandfather told us everything. About the Omnitrix, Gwen’s magic, about how the two of you were fucking each other silly, and especially about Gwen’s pregnancy.”

“But,” Ben stammered as his mother sucked the head of his cock into her mouth and down her throat.

“Ben, we’re not angry with you,” his father said as he knelt next to the couch and stroked her swollen belly with one hand as he reached down to tickle the girl’s erect clit with the other one. “We were hoping something like this would eventually happen, we were even planing on it, but we thought it would be another two or three years before you and Gwen started fucking. The fact that you managed to knock her up this summer means our plans are a good two years ahead of schedule.”

“Now I’m really confused,” Ben said as his prick started to harden in his mother’s warm sucking mouth.

“You’re not the only one,” Gwen groaned as her father sucked on her nipple to get the first drops of milk that oozed out of her tit.

“Maybe it’s time to tell the kids everything,” Grandpa Max said, running his hand through his short grey hair as he looked at all the naked bodies groaning and withing around him. “It may be a long story, but I think it’s time Ben and Gwen knew the whole truth.”

“Do you think they’re ready for the truth dad?” Gwen’s father asked as he licked his daughter’s milk from his lips.

“Gwen is already carrying Ben’s baby,” Grandpa Max pointed out, “and Jane is carrying two in her belly so I consider her family enough to hear the truth too. I just wish Keesha could be here too.”

“I guess you’re right,” Ben’s father said, “but it still seems strange to let the secret out after eleven years.”

“What are you talking about?” Jane asked as she looked from one adult to another. When Ben and Gwen’s parents had first entered the room she wanted to run and hide before anyone noticed her but when Ben’s father started playing with her pregnant body it felt so good that she’d managed to relax and enjoy it until now her curiosity was much stronger than her fear had ever been.

“It’s like this,” Gwen’s father said with a sigh as he stroked his daughter’s swollen belly. “The four of us were so close that we decided to do everything together – we even had a double wedding so we could get married on the same day. We all wanted children too – a lot of children – but after three years without a single pregnancy we began to think something was wrong. We finally decided it was time to have some tests run so we took advantage of our plumbers health benefits to get things checked out and found out that while your mothers were just fine – the two of us were sterile.”

“You were plumbers?” Ben asked as he looked from father to his uncle and then down to where his mother and aunt were taking turns licking his trembling cock and balls.

“That’s right,” Ben’s father said with a nod, “in fact the doctors thought that it was some of the strange alien energies we encountered as plumbers that made the two of us sterile.”

“But,” Gwen said as she tried to think past the cloud of pleasure that made her ache for a cock in her pussy, “if the two of you are sterile then what about Ben and me?”

“We’re getting to that,” Gwen’s uncle said. “After we found out that your father and I were sterile we thought long and hard about what we were going to do since all of us still wanted children. It finally came down to either artificial insemination or choosing someone else to father our children, and we realized there was only one thing to do if we wanted our family line to continue.”

“Is this leading to where I think it’s leading?” Jane asked as she looked from Gwen to Ben and started thinking about how much they looked alike even for cousins.

“I think it is,” Grandpa Max sighed before either of his sons could speak. “You see, that’s where I came in. You see Ben and Gwen, your parents realized that the only way the family line could continue would be for me to father their children. Your parents knew that I was really wild in my youth and they figured it wouldn’t be that hard to bring out the beast in me again if they could create the right conditions. But they also knew that your grandmother would never approve or understand so they had to wait for just the right time. Your grandmother was off to one of her quilting conventions when Gwen’s parents invited me to dinner one night. I knew something was up because of the way the conversation was going during the meal, but I had no idea what was going to happen when Ben’s parents showed up after dinner.

“I can’t remember who it was who suggested playing poker that night but the next thing I knew things had devolved into strip poker and I was facing two nearly naked girls while my sons watched in anticipation. By the time my two daughter-in-laws were down to nothing but their panties I couldn’t keep my eyes off their naked tits while my own cock twitched at the thought of fucking the two of them. Once they knew that I was willing to fuck your two mothers they told me everything, of course by that time I was so horny I would have agreed to anything for a chance to fuck those two hot girls – and knocking the two of them up was such a small price.”

“Is that why Ben and I have the same birthday?” Gwen asked her father as he sucked on her nipple.

“While you were conceived on the same night,” Gwen’s mother said as Ben’s mother took her turn sucking Ben’s cock, “but it was pure luck that you were born on the same day.”

“Wait,” Ben said with a shiver as his mother ate his cock, “that means Gwen is my sister doesn’t it?”

“Half sister,” Grandpa Max confirmed, “same father different mothers. Your father and uncle are your half brothers for the same reason.”

“This is getting weird,” Jane groaned as Ben’s father finger fucked her.

“If you think it’s weird just think how I feel,” Gwen sighed, “I thought it was bad enough when I was so hot for my cousin I couldn’t stop fucking him – especially after he knocked me up – now I find out that Ben is actually my half-brother and I want Ben’s cock even more than before.”

“But if you wanted a lot of children,” Ben said as he looked down at his mother and aunt, “than why did you stop with just Gwen and me?”

“Well we didn’t plan to,” his mother said, “but no matter how many times we fucked your grandfather after that first time he never managed to knock us up again – not that we ever complained about fucking him time after time.”

“I always suspected there was a reason I never managed to knock your mothers up again after that first time,” Grandpa Max said with a sheepish grin, “so when I took Gwen to see the doctor I had him run some tests on me as well. It turns out that it took longer on me, but the same alien energies that made your father’s sterile affected me as well. And that’s why you never even had a chance for any bothers or sisters – until now that is.”

“What’s changed?” Ben asked as he gave his grandfather a puzzled look, “did the doctor give you something to reverse the sterility?”

“Silly boy,” Ben’s aunt said as she gave him a wide grin, “haven’t you figured it out yet?”

“Ben can be a little slow on this sort of thing,” Gwen said as she gave her mother a knowing wink. “From what Uncle Greg said earlier it sounds like the five of you were planing to have the two of us fucking each other – probably to get us use to the idea of incest before you got Ben to knock you up with his own brothers and sisters. Am I right?”

“Yes you are,” Gwen’s mother said, proud of the way her daughter had put everything together so easily. “The idea was to put you and Ben together for the summer – isolated from other kids your age for the most part – so that when the two of you got horny you only had one person to turn to to satisfy your urge to fuck. We thought it would take two or three years before you were horny enough to start fucking, so imagine our surprise when your grandfather called to tell us that you were already fucking – and when he told us that you were pregnant with Ben’s child we knew it wouldn’t be long before he was ready to knock us up as well.”

“But why did you wait this long?” Ben asked as he looked down at the top of his mother’s head. He was already looking forward to stroking in and out of her wet pussy and he knew that his mother and aunt would both be knocked up after he fucked them tonight.

“We weren’t sure if you were really ready yet,” Gwen’s mother said. “It wasn’t until after I overheard Gwen and Jane talking about Keesha that we knew you were ready for the truth. What do you think Ben, are you ready to fuck your mother and aunt and knock them up?”

“Fuck yes,” Ben said as he gave his mother and aunt a lust filled grin.

“What about you Gwen?” Ben’s father asked as he pulled his fingers out of Jane’s pussy and sucked them clean, “are you ready and willing to fuck your father and uncle even if they can’t knock you up?”

“Ready, willing, and hungry for your cock,” Gwen said as she licked her lips.

“Don’t forget me,” Jane said as she grabbed Ben’s father by the wrist and gave him a hopeful smile, “I want to fuck the two of you too.”

“I was hoping you’d say that,” Ben’s father said as he stroked Jane’s drooling slit.

“You know,” Grandpa Max said as he looked around the crowded den, “it’s getting a little crowded in here, maybe we should split up before we end up fucking on top of each other.”

“Good point,” Gwen’s father said as he stroked the red fur around his daughter’s wet cunny. “Ben, why don’t you go to the master bed room with your mother and aunt, and five of us will go to the girls room to fuck.”

“Ok,” Ben said as he pulled away from his mother and aunt and got to his feet before he helped them stand. And after that maybe we can all get together in the living room for a free for all.”

“Sounds good to me,” Grandpa Max said as he helped Gwen to her feet. “We’ll see you in a few hours then?”

“Maybe we should make that in the morning,” Ben’s mother said before she followed Ben out of the den. “By the time we finish with Ben he’ll need his sleep.”

“And I think we will too,” Gwen said as she gave her father a quick grin. “So we’ll see you in the living room in the morning.”
