My BBW Stepsister

Literotic asexstories – My BBW Stepsister by Thrognar,Thrognar “CJ, I need to talk to you.”

“Just a second mom,” I said, not taking my attention away from the online game of Crash Team Racing: Nitro Fueled I was playing with my friends. “Yes! First place. I got this in the bag! What the…? Who the fuck…? Oh you bastard! NO! Oh my god, I hate you!”

I had been sitting in my room playing with my friends online for the last half hour. I heard the front door when my mother came home, and I heard her footsteps on the stairs. However since I was engrossed in the game, and was in first place I kept my attention focused on the game. One of my friends hit me with a powerup, knocking me out of first place allowing him to pass me and win. He was laughing at me.

“I’ll get you next time. Look guys I gotta go. My mom needs to talk to me.” I said, “I’ll catch you assholes later.”

I logged out of the game, took my headset off and turned my attention to mom.

“So what’s up mom?”

“You know that guy Dean I’ve been seeing?” she asked, sitting down on my bed.

I guess I should give a little background here. My mother Donna and my father Ethan had gotten divorced seven years ago when it came out that my father was having an affair. He had managed to keep it a secret from mom and I for almost two years. Then one day dad left his phone unattended and unlocked (which he almost never did) and his mistress texted him. I happened to be in the room when the text came in so I grabbed the phone and walked into the kitchen where my parents were, where I unknowingly exposed my father for the cheater he was.

“Hey dad, who’s Christina and what does she mean by ‘Have you told her yet?'” I asked, “Oh wait, another message just popped up, ‘I can’t wait until you’re all mine. Divorce that bitch already’.”

Dad tried to snatch the phone out of my hands, but mom was standing closer to me, and beat him to it.

“CJ, go to your room.” she said, looking at the phone before staring daggers into my father.

I was only fifteen at the time, so I did as I was told, but I wasn’t stupid. I knew full well what those messages meant. Even if I hadn’t, I could clearly hear the shouting match (well, mom shouting) even though I was upstairs in my room with the door closed. My mother demanded the truth and eventually my father broke down and admitted everything. He had been seeing Christina behind my mother’s back for almost two years. She was also married, but she was ready to divorce her husband (in fact, she had already set the wheels in motion) and marry my father. All he had to do was divorce my mother. When he didn’t immediately comply with her demands to leave my mother, Christina gave him an ultimatum, either he tells my mother about them… or she would. Once he confessed to the affair my mother immediately kicked my father out (the house was in her name) and filed for divorce the next day.

I was old enough to decide which parent I wanted to stay with, and since I had always been closer to my mother, I opted to stay with her. Don’t get me wrong, my father didn’t neglect me, in fact he was a very good father. When I was little, we did all the typical father/son bonding things. He taught me how to ride a bike, played catch with me, taught me how to swim, and things like that. But my mother was the one who would do things like take care of me when I was sick or hurt, comfort me whenever I had a bad dream, help me with my homework, would take me to meet my friends for things like birthdays or sleepovers, went to all the parent/teacher meetings at school, took me to the park, the zoo, and things like that. If I had to break it down to percentages, I’d say it was a 60/40 split in favor of mom.

For the next few years it was just mom and I. After a rather ugly divorce, dad only stayed in touch to pay the alimony, but that was pretty much it. My parents mostly talked through their lawyers, and that was only when they had to. Once everything was settled the only contact we had with him were the monthly alimony checks, and a couple of birthday cards. My parents haven’t spoken to or seen each other since I was sixteen. Last I heard Christina went through an equally ugly divorce with her husband, and she and my father eventually moved out of town. I have no idea if they actually got married or if they’re even still together, nor do I care. My mother was my main concern, I did my best to be there for her when she would bounce back and forth between angry, depressed and hopeless. She often told me if it wasn’t for me, she wasn’t sure she would have made it through with her sanity intact.

Mom decided to get back into the dating scene just before I left for college. While I was away at school, we would talk on the phone about 2 or 3 times a month and of course when I came home for vacation but she didn’t really talk much about her dating life. She would occasionally mention some nice guy she’d met, but things never seemed to work out. Until she met Dean. She admitted it was love at first sight, and had sent me a couple of pictures of him. I had to admit, Dean was a pretty good looking guy, and I had to laugh when my mom would talk about him like she was a teenage girl instead of a middle aged woman with a college aged son. She had started seeing him full time a few months before I graduated college.

After college, mom let me move back in with her until I could get a job and move out on my own. I was actively looking, but nothing had come up just yet, and mom wasn’t rushing me to get out on my own. She had gone out several times on dates with Dean since I had come back home, but I had yet to meet him.

“Yeah, what about him?” I asked.

“Well, I figured it’s about time you met him. So we’re having dinner at his place tomorrow.” mom said.

“Wow, you’re really serious about him aren’t you?” I asked, “I mean you’ve been with him for what… eight months now?”

“Nine,” mom corrected me, “But yeah, I am pretty serious about him. This is the longest relationship I’ve had since the divorce. He’s got a daughter your age too.”

“Yeah, I remember you mentioned her a couple of times before.” I said, “Sheila? Shirley?”

“Shelby.” mom said, correcting me again.

“Right, Shelby.”

“She’s going to be there too.” Mom said, “So I hope you don’t have any plans.”

“Well you know, I was gonna sit around, watch some TV, maybe play some video games, surf the net and scratch myself, but I can cancel.”

Mom laughed, “If it’s not too much trouble.”

“I’ll pencil you in.” I said, also laughing.

The next night we found ourselves outside Dean’s house, mom seemed a little nervous as she knocked on the door. I guess she was hoping I’d like Dean, she hadn’t actually said as much, but her body language gave her away. Dean opened the door with a big smile on his face.

“Hi babe,” he said to mom, giving her a quick hug and turned to me, extending a hand, “And you must be CJ.”

“Nice to finally meet you. I was beginning to think you didn’t exist. I figured mom just took a stock picture of a guy off the internet and photoshopped herself into pictures with him.” I said, shaking the offered hand.

“CJ!” mom said, laughing and giving me a good natured swat on the arm. Dean just laughed.

“Nice to finally meet you too,” he said, “Your mother’s told me a lot about you.”

“Not everything I hope,” I said, smirking, “Because those farm animal stories are NOT true!”

“See? See what I mean?” my mother said, gesturing at me, “He’s been like this ever since he hit puberty.”

Dean ushered us inside.

“This is my daughter, Shelby.”

My eyes went wide and a smile spread across my face. Shelby was absolutely gorgeous. She had captivating hazel eyes, an addictive smile, and her dark brown hair with purple highlights framed her face perfectly. She was also fat. Which was fine with me.

I’m a self admitted chubby chaser. I can’t explain it, but I’ve always been attracted to bigger women. Every girl I ever dated was a self-admitted fat girl. My first girlfriend, Jill (well it wasn’t really official, since we were both 10 years old) was a big girl. Then there was my first real girlfriend when I was 13, Marissa, followed by Kelly, Charlene, and Erin. All of them had a little extra cushion for the pushin’, if you catch my meaning.

While none of my girlfriends fit into the “conventional standards of beauty” that the media, TV, movies and magazines forced on us, I learned from my mother that it didn’t matter what a person looked like on the outside, but who they were on the inside. I learned pretty quickly how true that was. Most people who fit into the aforementioned “conventional standards of beauty” were (at least in my experience) some of the meanest, rudest, most self centered people I have ever met. While people who didn’t fall into those standards were just the opposite. But like I said, that’s just my experience, your mileage may vary. Not to say that any of the girls I dated were ugly (at least not by my standards), they just weren’t built like supermodels.

Shelby’s eyes lit up when she saw me. Now I’m not some buff guy with movie star looks (the aforementioned “conventional standards of beauty”), but I’m not ugly either. I sometimes undersold myself saying I was just average looking, but my mother and my girlfriends told me I was not “just average”. Mom always told me I was very handsome, while my girlfriends always told me I was pretty hot. Even girls who were just friends of mine told me I was pretty good looking.

“Hey, how are you?” I finally managed to say.

“Good,” she said, “Nice to meet you.”

“You two go and get acquainted,” Dean said, ushering us into the living room, “Dinner will be ready soon.”

Shelby and I made ourselves comfortable on the couch and started talking about anything and everything. Much like me, Shelby was living with her dad until she could get a job and move out on her own. We discussed our interests and found we had several in common, however some things I was into didn’t interest her and vice versa, but we still had a lot to talk about while mom and Dean worked their magic in the kitchen. About a half an hour later we all sat down to eat. All four of us just making pleasant conversation, with mom and Dean peppering in embarrassing stories about me and Shelby. When we were just about done, mom and Dean looked at each other and then at Shelby and I.

“Kids, there’s something we need to tell you,” Mom said, reaching over to take Dean’s hand, “The reason we brought you here tonight is because, well… Dean and I are getting married.”

My eyes went wide, I opened my mouth to say something, found myself at a loss for words, closed my mouth again, screwed up my face into a look I got when I was trying to understand what was going on, glanced over at Shelby (who had a similar shocked look on her face), opened my mouth again, and finally said, “What?”

“We’re getting married,” Dean repeated.

“Married as in ‘Till death do us part’ and all that?” Shelby asked.

“Something like that.” Dean said.

“Mom, I know you’re a grown woman and all, but you’ve only known each other for a few months,” I said, “Don’t you think you’re rushing things a little bit?”

“Your grandmother said the same thing,” mom said, “So I’m going to tell you the same thing I told her. It just feels right, I feel the same kind of connection to Dean that I felt when I first met your father.”

“And we saw how well that ended,” I said, smirking, then I turned to Dean, “Look, you seem like a really great guy, my mom sounds like a lovesick teenager when she talks about you, but this is a lot to take. You can’t just drop a bombshell like that on us. You didn’t even try to cushion the blow, you could have eased us into this. This is why you were so nervous, wasn’t it?”

“We just felt it better to lead with that, instead of bullshitting around,” Dean said, “We figured you’re both smart enough that if we tried to sugarcoat it you’d figure it out, and wonder why we didn’t just tell you.”

“He’s got a point,” Shelby said. “One thing I can say about my dad is he’s always been a ‘get right to the point’ kind of guy.”

“Just promise me you won’t give me the ‘I’m not trying to replace your dad’ speech,” I said, “Because my dad was kind of an asshole.”

“CJ!” mom yelled at me.

“Well he was,” I said turning back to face her, “If he wasn’t you wouldn’t be with Dean right now. I mean he cheated on you for two years! That’s an asshole move in my book.”

“Don’t worry,” Dean said, “I’m not going to give you that speech because I already made your mother promise she wouldn’t give Shelby a similar speech about replacing her mother.”

Dean’s wife had died when Shelby was only ten years old from breast cancer. It took him a long time to even consider dating, and in fact, my mother was the first serious relationship he’d had since her death. I let out a long breath and realized I had tensed up and relaxed.

“I’m sorry mom,” I said, “I shouldn’t have reacted like that. I guess I’m still a little sore over what dad did. But if Dean makes you happy, then I’m happy for you.”

“Yeah,” Shelby said, “Same goes for me dad. You’re both consenting adults, and you seem to be happy together.”

“This is going to sound kind of weird,” Dean said, “But we did kind of want your approval on this. This is a big step for all of us, and as comfortable as Donna and I are with each other, it would mean the world to us if you were on board with this too. We’re going to be a family, and I’d love it if we all got off on the right foot, so there’s no underlying tension.”

Shelby and I looked at each other.

“You wanna be my stepsister?” I asked her casually, as if I was asking about the weather.

She smiled, “Sure.” she answered, just as casually.

I turned back to mom, “Ok, we’re on board. So when’s the wedding?”

It turned out to be two months later, and mom and I would be moving in with Dean and Shelby. In fact mom had already started working with a realtor to put our house on the market, and over the next couple of weeks we moved our stuff into Dean’s house. Anything we didn’t need or want was sold, given away or donated. Mom got a pretty good deal on the house too. Dean’s house had three bedrooms, the third had been a combination storage room/office but became my bedroom, which was right next door to Shelby’s. The wedding was a small affair held in the backyard with a justice of the peace. Not counting Shelby and I, mom and Dean’s parents, there were only about ten guests total.

In the weeks leading up to the wedding I wasn’t sure if I was imagining it or not, but it seemed like Shelby was teasing me. Maybe it’s because I was infatuated with her and it was just wishful thinking, but it seemed like she would wear shirts that showed off a generous amount of cleavage, and most of the time she wasn’t wearing a bra. A few times she would bend over and show off even more cleavage, or would have her back to me so I could admire her ample ass. If she was doing it on purpose, she managed to play it off like she had no idea what she was doing. If she wasn’t doing it on purpose, I always averted my eyes before she could notice me staring. During most of our conversations she would make raunchy jokes, and drop sexual innuendos. She would go out of her way to be next to me if we went out together as a family, she would snuggle next to me when we watched TV, and when she would hug me she would hold the embrace for a few moments longer than was probably necessary.

In the days leading up to the wedding she would ask my opinion of different dresses she was considering.

“It’s not easy to find nice dresses when you’re a fat girl.” she said one day as she modeled for me. “At least not ones that don’t look like a fucking circus tent. I mean I know I’m fat, but I’m not huge.”

This was not the first time Shelby had referred to herself as fat. She had made several self-deprecating fat jokes the first night I met her, and in the weeks since.

“Don’t be ridiculous,” I said, “You look fine.”

“You really think so?” she asked.

“Yeah,” I said, “And I still like that blue dress you showed me yesterday.”

After the wedding it became apparent to me that she was in fact teasing me as we became more comfortable around each other. It was very obvious that she wasn’t wearing a bra most of the time, and the incidents of her bending over to show off her cleavage or her ass happened more frequently (especially when she didn’t need to). She would make a big show out of letting the steam out of the bathroom when she finished showering, pretending to check herself out in the mirror wrapped in a towel that barely covered her pudgy body making sure I could see her, and she would come to my room to say goodnight to me wearing a nightshirt, that much like the towel, just barely covered her crotch. I started teasing her back, for example whenever I was getting dressed, I’d make sure to pull my shirt on once I determined Shelby would be able to see me without it on for a few seconds, making equally raunchy jokes during our innuendo laced conversations, pressing my body into hers when we hugged, and “accidentally” brushing her tits with my arm when we would sit and watch TV together. I’d also let the steam out of the bathroom after my showers with just a towel wrapped around my waist making sure she could get an eyeful, and since I only ever slept in just a pair of shorts, I would sometimes go to her room just wearing my shorts to say goodnight to her. Somehow our parents never picked up on this, or if they did suspect something was going on between us, they never said anything since we hadn’t actually done anything.

I had broken up with Erin after college as she lived several states away and neither one of us were interested in trying a long distance relationship, so I was currently single. Shelby mentioned an ex-boyfriend during our conversations, but never mentioned a current one. So with the teasing driving me crazy, my only release was masturbation. Almost every night before going to sleep, I would whip out my dick and masturbate to a myriad of sexual fantasies starring Shelby and I.

A couple of weeks after the wedding fantasy would become reality.

“Hey mom,” I said, finding her in the kitchen, “You remember my friend Jay?”

“Is he the tall one with the lisp?” Mom asked.

I laughed, “No, that’s Justin. Jay’s the tall lanky one who looks like Trent Reznor.”

“Oh, right, him.” Mom said, “What about him?”

“Well today’s his birthday, and he’s having a little get together at his place tonight. So I was wondering if I could borrow your car?” I asked.

“How little?” mom asked.

“About ten or twelve people.” I said, double checking the text Jay had sent me.

“What time?”

I again glanced at the text, “It says here it starts at eight, and you know us, it’ll end whenever.”

“I remember your friend’s parties that went until ‘whenever’.” Mom said, “That means you might not be back until tomorrow morning. I’ve still got to go to work, you know.”

Shelby had walked in during our conversation, “I don’t have any plans for tonight. I can take him.”

“I should be able to crash there, and Jay’s mom can drop me off in the morning.” I said.

“Is that okay with her?” mom asked.

“Lemme ask.”

I sent a text to Jay asking if his mom would be cool with it, he answered back saying his mother had the day off from work so she’d have no problem bringing me home. I relayed that information back to mom who agreed to let me go if Shelby was willing to drive me.

“Thanks again for doing this,” I said, later that night as we drove to Jay’s house, “I really appreciate it.”

“Oh it’s no problem,” Shelby said, “I don’t mind, after all you’re my brother now.”

“That’s his house, up there on the left.” I said, pointing. “You wanna come in for a minute? Meet my weird friends I’ve been telling you about?”

“No, that’s okay,” she said, “I know me and parties. Get a couple of drinks in me and next thing you know I’ll be twerking on the coffee table or something.”

“Really?” I asked, arching an eyebrow.

“Really.” She said, “You haven’t lived until you’ve seen a fat girl twerking. Especially when you’ve got an ass like mine.”

“Oh, you and I have to go out drinking sometime. I want to see drunk Shelby.” I said, laughing.

She laughed as well, “Maybe some other time.”

“I’m gonna hold you to that.” I said, leaning over to give her a kiss on the cheek. “Thanks again.”

I got out of the car and headed inside. Justin and I ended up staying after the party to help Jay and his mom (who spent most of the time in her room watching TV) clean up and I crashed on the living room couch and Justin took the couch in the den.

The next morning as promised Jay’s mom drove Justin and I home, dropping me off first. I noticed both mom and Dean (I still hadn’t gotten around to calling him dad yet) had already left for work. I was humming to myself as I let myself into the house and headed upstairs with the intent of getting out of the clothes I’d slept in and getting in a quick shower. That thought died in my mind a few steps from the landing as Shelby emerged from the bathroom naked as the day she was born, also humming a tune to herself. Due to the way the house is set up, the top of the stairs directly faced the bathroom that Shelby and I had to share. Mom and Dean’s bedroom was to the right, and it had its own bathroom. Directly opposite their room was Shelby’s room with mine right next to it. So far there hadn’t been any “accidents”, just the teasing after showers. As much as I wished for a little more, I wasn’t crazy enough to try anything. Sure, she and I weren’t being subtle anymore with teasing each other, but what if my mother or Dean caught us?

We both abruptly stopped humming and were frozen in place. I took the moment to drink in the sight of her gorgeous chunky body as she made no move to cover herself or close the short distance between the bathroom and her room. I could feel the blood rushing to my cock as I finally laid eyes on the body I had spent almost every night fantasizing about. Shelby, figuring since she was home alone, didn’t need to worry about wrapping herself in a towel or her bathrobe as she took her morning shower. She definitely wasn’t expecting to be caught by me. I finally broke my paralysis and climbed the final three steps to the landing, closed the short distance between Shelby and myself, took her face in my hands and leaned down to kiss her. She wrapped her arms around me and pressed her plump naked body against me.

We broke the kiss and looked longingly into each other’s eyes, and without a word, Shelby took my hand and led me into her room. She sat down on the edge of her bed and without hesitation started working on getting my pants off. She pulled my pants down and her eyes went wide at the sight of the bulge in my underwear. She quickly pulled those down and gasped in surprise as my fully erect cock sprang into view. She looked up at me and smiled as she wrapped her hand around my member. Then without a moment’s hesitation she engulfed all of my eight inches in her sweet warm mouth. I moaned in pleasure and my head lolled back and I closed my eyes. I let out a long gasping breath as Shelby started eagerly sucking my cock like I had dreamt about for weeks.

She wasn’t being elegant about it either. She was literally drooling and making obscene slurping noises as she inhaled my cock. I reached down to fondle one of her massive tits that she had been teasing me with for the last few months. She moaned as I pinched her nipple, but didn’t stop her head bobbing back and forth as she greedily gobbled my tube steak. I pulled my shirt off and tossed it off to the side, kicked my sneakers off and Shelby caught on and pulled my pants and underwear off so I was just as naked as she was.

She went right back to hungrily stuffing my cock into her mouth. I reached down and grabbed her head and started controlling her movement. I noticed her hand had slipped down between her thighs and pulled her off my cock. She gasped in shock but realized what I wanted without me saying a word. She scooted backwards until she was in the middle of the bed, and I followed, crawling over her voluptuous body, hovering over her before we kissed again, this time with the same ferocity Shelby had used on my cock. I lowered my head a bit and took one of her massive tits into my mouth, sucking on her thick nipple, earning a moan of pleasure, before she pulled my face back up to hers and planted another steaming hot kiss on my lips.

When we broke the kiss I licked a couple of my fingers and slid them between her legs. Not that I needed to, she was already soaking wet with anticipation. I slid my fingers into her warm opening, and she squealed with pleasure as I pushed my fingers as far into her as they would go, pulled them out and with my cock still sufficiently lubed with her saliva, I parted her thick thighs, and slid my cock into her, both of us moaning with pleasure as I pushed my dick all the way inside my stepsisters steaming slit.

I started fucking Shelby, slowly at first, but picking up the pace as we worked together, still not having said a single word. She wanted this just as much as I did, and we quickly found the perfect pace. Me on top of Shelby’s plush body, slamming my cock into her, and her moans of pleasure intermingled with the slap of our hips meeting and my grunts of pleasure. We alternated looking deep into each other’s eyes and passionate kisses as we fucked. I could feel the sweat forming on my body, but it was barely a concern. I watched Shelby’s body jiggle underneath me as I continued driving my cock into her. The look on her face said more than any words ever could.

“Oh god,” she moaned, the first words either one of us had said, “That feels so fucking good, CJ. You’re gonna make me cum.”

“Cum for me Shelby,” I grunted, “Cum all over your stepbrother’s hard fucking cock.”

“Oh my fucking god!” Shelby groaned, and a moment later she let loose with a wordless scream of pleasure that I was sure the neighbors heard.

I felt Shelby’s cunt contract around my thrusting cock, and the warmth as her orgasmic juices leaked out, further lubricating my pumping member. Shelby pulled me down for another kiss, moaning into my mouth as she came down off her orgasmic high.

“Your turn,” she said breathlessly as we broke the kiss, “Cum inside me. Pump me full of your fucking cum. Cum inside my fat juicy pussy.”

I was already pretty close to the finish line, and the look in her eyes, the sight of her beautiful buxom body underneath me, the warmth of her pussy and her words all combined to push me past the point of no return.

“Oh fuck, I’m cumming!”

I roared in pleasure as I slammed my cock deep inside Shelby and exploded, firing what felt like 7 or 8 blasts of cum inside her warm, receptive pussy. I buried my face in her fleshy shoulder and moaned as I drained myself dry before slowly pulling out of her. I picked my head up and we exchanged another kiss, with less ferocity than before as I rolled off of her and onto my back next to her.

For a few moments we just lay there, I stared at a slice of sunlight on the wall as I tried to catch my breath. Finally we turned to look at each other.

“I’ve been wanting that ever since I first laid eyes on you.” she said. “My first thought was ‘Holy shit, he’s cute’, immediately followed by ‘I wonder what he’s like in bed’.”

“I was thinking the same thing.”

“Then why did it take you so long to pick up on the hints I was dropping? I was thinking I would have to take off my clothes in front of you for you to get the hint.” she said.

“Because I’m kinda stupid,” I said, being a little self deprecating, “I wasn’t sure if you were doing it on purpose or if I was just getting lucky and you honestly had no idea your tits were practically falling out. Once I was sure it was on purpose, I started reciprocating.”

“So is it just me, or do you have some kind of fat fetish?” she asked, “Because I’ll admit, most guys were turned off by my weight. They’d always say shit like ‘Shelby, you’re cute and all, but you could stand to lose a few pounds’, and it always pissed me off. My last boyfriend was the same way, he’d drop subtle hints about wanting me to lose weight. It’s one of the reasons we broke up.”

“Well to be totally honest, I like you because of your weight,” I said, and she looked at me with surprise, “So yes, I do have a fat fetish. I always have. I can’t explain it, but BBW’s turn me on. All my girlfriends have been big girls like you.”

“BBW’s?” Shelby asked, looking over at me.

“Big beautiful women,” I said, “You mean to tell me you’ve never heard that term before?”

“No,” she said, “I guess no one ever had the guts to say it to my face.”

“I didn’t upset you did I?”

“No,” She said, brushing a lock of hair out of her face, “You can call me whatever you want.”

“I can’t tell you how many times I’d be laying in bed on the other side of that wall and masturbating to thoughts of fucking you.”

“Probably about as many times as I did,” she said, “Every time I would hear you get up in the middle of the night to go to the bathroom, I was hoping you’d come in here and fuck me. You have no idea how much self control it took for me to not go to your room in the middle of the night and have my way with you.”

“Honestly I’m surprised our parents haven’t picked up on our not so obvious flirting with each other,” I said.

“I know right?!” Shelby said, throwing her arms up, which made her massive tits jiggle, “I’m thinking I could have probably given you a blowjob in front of them and they wouldn’t have batted an eye.”

“Well, I wouldn’t go that far, but it’s gonna take a lot of self control not to grope you when we sit and watch TV together.” I said. “Our parents may be oblivious to our flirting, but I draw the line at fucking you in front of them.”

Shelby laughed, and again I watched her thick body jiggle, “Okay, maybe not that far, but yeah, it’s gonna be hard for me to keep my hands off of you from now on, even when they’re around.”

“Well, they’re not around right now,” I said, smiling and wiggling my eyebrows.

“No, they’re not,” Shelby said, also smiling.

“So lemme ask you,” I said, eyeballing her tits. “You ever been tit fucked?”

She pushed her massive mounds together. “No, most of the guys I’ve been with just wanted to fuck me or have me blow them. They liked playing with my huge tits, but that was about it. Like I said, most of the guys I’ve been with would always make comments about how much better looking I’d be if I lost weight. They’d fuck me first, probably because they correctly assumed that saying something like that wouldn’t get them in my pants. Then after the fact they’d tell me I need to lose weight, we’d argue and eventually break up.”

“They don’t know what they’re missing.” I said, “Well fuck ’em, their loss is my gain.”

“Exactly,” Shelby said, “Us fat girls need dick too.”

I got up and straddled Shelby’s chest. My cock was already back at full mast, and I placed it in the sweaty valley between her impressive fun bags.

“I can’t believe you’re already hard again,” she said, pushing her tits together around my cock, engulfing it in the warmth of her bra busters.

“I usually just need a little rest before I’m ready to go again,” I said, grabbing the headboard of her bed to steady myself. “Plus, it doesn’t hurt when I’ve got someone as hot as you to fuck.”

“It doesn’t hurt that I’ve got someone as hot as you fucking me. Especially with that huge cock of yours. Exactly how big are you?” she asked.

“Eight inches.” I said.

“Definitely bigger and thicker than any other guy I’ve fucked.” she said, “Now how about you slide that eight inch cock between my big ol’ titties.”

“Exactly how big are we talking here?” I asked, “I’ve seen some big tits in my life, but yours are enormous.”

“38F,” she said proudly. “Now stop talking and tit fuck me. I want to know what it feels like to have a huge cock sliding in between my huge tits!”

So I did. I was still slick from fucking her, I used that and the sweat on her body to lubricate my cock as I tit fucked my stepsister. She teased me by occasionally sticking her tongue out and licking the head of my cock as it peeked out from in between her mammoth mounds. She moaned with pleasure and my cock slid back and forth between her gargantuan gazongas. She was only the second girl I ever tit fucked, out of my past girlfriends only one let me tit fuck her, and she sported an impressive pair of 36DD’s.

I don’t know what it was about Shelby that had me hooked, but something about her had me hotter for her than any of my past girlfriends. It wasn’t just her thick body, or her gorgeous face. It wasn’t just the fact that she found me just as attractive as I found her, or the fact that she wanted my cock as much as I wanted to give it to her. Whatever it was, I silently thanked whatever cosmic forces had bought my mother and Dean together. Because if it wasn’t for that, I never would have met Shelby, and I wouldn’t be sliding my prick between her fucking massive mamarries. Check that, I wouldn’t be about to cum all over her huge fucking knockers.

“Oh fuck, Shelby, I’m gonna cum again!” I groaned.

“In my mouth,” she panted, “I wanna taste your cum.”

I pulled my cock out from the warm embrace of her fleshy globes and aimed the head of my cock at her open mouth. I groaned as I fired off my second load of the day into her mouth, the first spurt of cum flew from my cock before I got my dick into her mouth, and she eagerly swallowed the rest of my cum as I filled her mouth with my seed. When I finally finished emptying my balls into her mouth I collapsed on the bed next to her again.

“Holy fucking shit.” I gasped, “You are fucking amazing.”

“So are you.” she said, “We’re gonna do that again, right?”

“That and so much more.” I said.

“I think I’m gonna need another shower.” she said, looking down at her sweat covered body.

“Not before I eat your pussy.” I said.

“Really?” she said, legitimately surprised.

“Don’t tell me no one’s ever eaten you out before?” I asked, just as surprised.

“No, like I said, most guys wanted me to blow them, but would never return the favor.” she said.

“Well, allow me to show you what you’ve been missing.” I said, making my way down her body.

She parted her thighs for me, and squealed in pleasure when she felt my tongue touch her clit. I could still taste her juices from her first orgasm, and as I licked and sucked every inch of her honey pot, more leaked out. Shelby was writhing and squirming, moaning in pleasure as I ran my tongue over her thick pussy lips. She gasped in pleasure as I eased two of my fingers inside her and started finger fucking her while I sucked on her hard little clit.

“Oh my fucking god,” she gasped, “I… I… OH FUCK!”

She grabbed my head and held me in place, wrapping her sizable thighs around my head, and screamed in orgasmic bliss as she gushed into my mouth. I wasn’t prepared for the amount of pussy juice she released. I did my best to swallow all of it, but a lot of it ended up running down my chin and dripping onto the bed sheets.

“Goddamn, I’ve never cum that hard before, or that quickly.” she gasped, finally releasing me. “That was fucking amazing. You’ve got it all, a hot body, a huge cock and a talented mouth. You’re the best stepbrother ever!”

“You’re not so bad yourself,” I said, wiping my mouth, “You’re gorgeous, you’ve got huge fucking tits, a delicious pussy and a body that won’t quit.”

“Now about that shower. Care to join me?”

“Try and stop me.” I said, as we got out of bed.

By the time our parents got home that night, Shelby and I had agreed that we would do our best to control ourselves around them. Because we had already tasted the forbidden fruit and given in to our impulses, we were (mostly) able to control ourselves for the rest of the night.

“Don’t forget that next week we’ll be going away for our belated honeymoon.” Mom said at dinner that night.

Since the wedding was a small affair, mom and Dean had decided to hold off on a honeymoon. The wedding had taken place on a Saturday and they were planning to go back to work until they could coordinate their schedules for a honeymoon. Dean had booked them a week’s stay at a resort and spa just outside of town. Since Shelby and I were both 22, they had no problem leaving the two of us alone for the week they’d be gone

Shelby and I shared a devious look.

“How’s the job hunt going?” mom asked.

Like I mentioned before, mom wasn’t rushing me to get out on my own, and likewise Dean wasn’t pushing Shelby out the door, but they did want us making the effort to find jobs.

“Well I have a couple of interviews lined up for next week.” I said.

“And I’ve got one this Friday, and I’m supposed to hear back either tomorrow or Monday from an interview I went to a couple of days ago.” Shelby said.

That night before we went to bed, I was sitting up in bed wearing just my shorts, checking my Facebook feed on my phone, when I saw movement out of the corner of my eye. I turned to see Shelby standing in the doorway, wearing her nightshirt.

“I had fun today,” she said quietly.

“Me too.” I said, smiling.

Shelby flashed me a mischievous smile and pulled up the front of her nightshirt enough to show me she wasn’t wearing any underwear. The sight of her neatly trimmed bush, that I had been balls deep in earlier in the day, made the blood rush to my cock. I could hear our parents moving around downstairs, it sounded like they were getting ready to retire for the night. I quickly pulled my now erect cock out for Shelby before we heard the sound of footsteps on the stairs and quickly covered up. Again I was amazed that mom and Dean didn’t notice us adjusting ourselves.

“So anyway, I just wanted to say goodnight.” she said, managing to sound casual.

“Night Shelby,” I said, with an equal amount of calm in my voice.

She winked and blew me a kiss and I heard her and our parents out in the hall exchanging goodnights. Mom poked her head into my room.

“Hey, hon, you got a sec?” she asked.

“For you mom, I have two.”

She rolled her eyes and smirked as she came over and sat on the edge of the bed next to me.

“I’m so happy to see that you and Shelby get along so well.” Mom said, “Dean and I were worried that since you’re both only children, that you might have trouble adjusting to having a sibling around, even if it is just by marriage.”

“Well, she’s a great girl,” I said, “We have a lot in common, and we have a bit of natural chemistry. I don’t know what it is, but we just click. Plus, I think we’re both past the sibling rivalry stage.”

“Well whatever it is, I’m glad everything worked out.” Mom said, leaning over to hug me, “Goodnight sweetie, I love you.”

“I love you too, mom.” I said.

Mom and I broke our embrace and she left the room, shutting the door behind her, I turned off the lights, pulled my shorts off and furiously masturbated while remembering what Shelby and I had done earlier that day, and what I planned to do with her in the future.

The next morning I felt someone shaking me awake.

“CJ? CJ, wake up!” Shelby’s voice broke through my sleepy brain.

“What, what is it?” I asked.

I opened my eyes to see Shelby standing over me, naked, shaking me awake, her tits jiggling as she nudged my shoulder. My cock immediately jumped to attention. I noticed her other hand was between her legs.

“Our parents just left for work, and I’m so fucking horny.” she said. “I’ve been thinking about you all night, I need to fuck you.”

I hadn’t bothered to put my shorts back on after masturbating last night, so I threw back the covers to show Shelby my erect cock, pointing at the ceiling.

“I’ve been thinking about you all night as well,” I said, “I’ve been dying to get back between your legs.”

Shelby quickly climbed into bed with me and straddled my hips, she leaned down, crushing her huge jugs into my chest and planted an urgent kiss on me, her tongue forcing its way into my mouth. I could feel the heat radiating from her pussy, and the hunger in her kiss. She pushed herself up, grabbed my cock and guided it into her already wet pussy.

“Oh my fucking god,” she groaned as she lowered herself on me until I was all the way inside her. “My fingers are no substitute for you. All I could think about all night was getting your cock back inside me. I must have masturbated to three or four orgasms, but it wasn’t the same. You’ve spoiled me, I don’t think I’ll ever be sexually satisfied again by anyone but you.”

“Well, like I said, I’ve been dreaming of the same thing too. I must have replayed yesterday 20 times, while also imagining everything else I’m going to do to you.” I said.

“Like letting me ride your thick fucking cock?” Shelby asked, slowly starting to do just that. “Watching my fat fucking body as I suffocate your cock inside my juicy cunt? Is that what you’ve been thinking about? Watching my big juicy titties bounce while I fuck you?”

“I’ve been thinking about sucking on those huge fucking tits,” I groaned, “All that wonderful warm tit flesh in my hands, those thick fucking nipples in my mouth, while I stuff my huge cock in your fat fucking snatch.”

“Like this?”

She hoisted one of her magnificent melons up to her mouth, and with a sultry look, stuffed as much as her tit into her mouth as she could. Much like when she sucked my cock, she made obscene slurping sounds as she sucked on her own boob.

“Is that what you wanted to do?” she asked, releasing her tit, her nipple and huge areola now covered in a thick coat of her own saliva. “You wanna suck on my huge tits?”

She lowered herself down, until her tits were in my face. She kept up the pace on my cock, making her tits sway as she lowered them towards my hungry mouth. I eagerly took the same tit that had been in her mouth into mine and she moaned in pleasure as I started teasing her nipple with my tongue. She started riding me harder as I switched to her other tit, and alternated, going back and forth between them.

“God yes,” she said, through gritted teeth. “Suck on my fucking fat titties while I ride your cock. I’ve been waiting all night for your cock to fill my pussy.”

“I could do this all day,” I said, finally letting myself come up for air.

“Good,” Shelby moaned, “Because we are. They won’t be home until well after 5pm and it’s only a quarter to nine… and holy fuck, are you making me cum already? Jesus, we just got–”

She was about to say “started”, but what came out instead was “staaaaaaaaaaaa–” and trailed off into an orgasmic scream as Shelby’s thick body was rocked by an orgasm. I watched in awe as her body jiggled as her orgasm ripped through her. She was alternately gasping for air and loudly moaning in orgasmic pleasure. Her pussy clamped down on my cock, and I could feel her juices leaking out of her, down my shaft, over my balls and down my ass to the bed.

When her orgasm had run its course, she threw her head back to get her hair out of her face.

“See what I mean about you spoiling me?” she said, “I’ve never cum like that before, and never so quickly. I mean usually it takes me a good few minutes to even get close, but with you, it’s like as soon as you get in me, I’m already on the edge. None of my other boyfriends could get me off that quickly.”

“Well you did say I was bigger than them.” I said, with no small amount of pride.

Shelby slowly pulled herself off my cock, now coated with her juices. She grabbed it and stroked it. “You are, but I never realized that a bigger cock would make me cum faster. Promise me something.”

“Anything.”

“That this is mine from now on,” she said, “That I’m the only girl who gets to suck your cock, the only girl you’ll ever fuck from here on out. My pussy, my huge tits, they belong to you now. I don’t want another man to ever touch me again. I just want my big dicked stepbrother.”

“And I want my BBW stepsister.” I said, “I promise. I’ve waited my whole life for a woman like you, and now that I’ve found you I’m never going to let you go.”

She smiled, released my cock, and kissed her way up my body until she was face to face with me. Our lips met and we exchanged another smoldering kiss. I rolled us over and pushed Shelby’s thighs apart, exposing her juicy cunt.

“God that’s fucking beautiful,” I said, looking not just as her pussy, but at her. Her thick body laid out for me, and only me.

“Fuck me,” she said, “Fuck that fat juicy pussy.”

“Roll over,” I said, “I wanna fuck you from behind. I want to look at your big juicy ass while I fuck the shit out of you.”

Shelby eagerly assumed the position and squealed in pleasure as I sank my cock into her warm opening. I grabbed her hips and she gasped in pleasure as I started hammering her for all I was worth. We didn’t say anything as we fucked, just a lot of moaning and groaning in between the sound of my hips slamming into her bountiful butt cheeks. The world faded away and all that mattered right now was fucking Shelby.

I was getting close, but this time I wanted to cum on her huge globes, and I wanted to see her face. I wanted to make her cum again before I came on her tits, I wanted to see my gorgeous stepsister’s o-face again. I pulled out, and Shelby let out a grunt of disappointment, until she felt me slap her ass.

“Flip over,” I said, “Spread those luscious thighs for me.”

Shelby immediately rolled onto her back and spread her legs again, allowing me to once again gaze upon her slick, juicy cunt. I surged forward, buying my cock deep inside her with one smooth motion. Shelby screamed in pleasure as I went balls deep in her.

As I started to fuck her again, she pulled my face down to hers and we kissed again.

“You feel so fucking good in me,” she moaned, “I’m so fucking lucky you came into my life. Now fill my cunt with your cum.”

“No, I’m gonna cum on your huge fucking tits.” I said, “But first I’m gonna make you cum again.”

“Then fuck me harder,” she said, wrapping her thick thighs around my waist.

I hammered Shelby as hard as I could, I could feel the sweat dripping off my face, and looked down at her, she was looking up at me with lust burning in her eyes. I moved my eyes down to watch her 38F’s bounce around on her chest as my cock penetrated her over and over again. Within no time, Shelby hit her breaking point.

“Oh fuck… I’m cumming! Oh shit!” she screamed, and let loose with an ear splitting scream of pleasure as she came again.

I could feel her clamp down on me again, and the warm flow of her pussy juice as her body vibrated beneath me as she rode out her second orgasm of the morning.

“I am never going to get tired of that,” she moaned, once she came down off her orgasmic high. “Now, you said something about cumming on my huge tits. Get that cock up here.”

She sat up just enough for me to get my cock into her mouth and started giving me another sloppy blowjob. She loudly slurped and slobbered all over my cock, licking her own juices off of it (she would later tell me she always licked her fingers clean after masturbating). The sounds she was making, along with the sight of her eagerly sucking me off was incredible. While my previous girlfriends liked sucking my cock, they were nowhere near as eager as Shelby was. She sucked my cock like it was an Olympic sport. She did things with her tongue that I didn’t think were possible. It felt like her tongue was everywhere at once, licking the vein along the bottom of my tool, wrapped around my shaft, teasing the head. If it were an Olympic sport, she just won the gold medal.

She looked up at me, and I lost it. I pulled out of her mouth and she pushed her tits together as I grunted in orgasmic bliss, stroking my cock over her titanic tits, shooting rope after rope of cum onto her mountainous melons. When I had drained myself dry, I rubbed the head of my cock on each of her cum covered nipples, before she took my cock back into her mouth and cleaned me up.

We lay in bed in post orgasmic bliss after that for a few minutes, talking over our new relationship.

“So what are we now?” she asked.

“What do you mean?” I asked, “I’m your stepbrother.”

“I know, but I mean beyond that.” Shelby said, “We can’t have a normal brother/sister relationship. I love you.”

“I love you too,” I said.

“No, you idiot. I’m IN love with you.” Shelby said, “Am I your stepsister or your girlfriend? Am I both?”

I opened my mouth and then paused, “I don’t know,” I finally said, “I guess I never thought about that. I mean what we did is technically incest even though we aren’t biologically related. I think just to be on the safe side, we should just refer to each other as step siblings so we don’t slip up and say something we shouldn’t.”

“It does make me feel a bit naughty if I just think of you as my brother.” she said, smiling and giggling a bit, “My big dicked, chubby chasing brother.”

“And you’re my big boobed, cock hungry sister.” I said.

We shared another kiss and decided to hop in the shower, although we didn’t get much washing done. After soaping up her huge tits, I ran my hand between her legs and fingered her to another intense orgasm, and she paid me back by soaping up her hands and masturbating me to a satisfying orgasm of my own.

Despite having seen each other naked, we felt weird walking around the house naked, so I threw on shorts and a t-shirt, and Shelby threw on a pair of shorts and a tank top that barely contained her huge tits. We made ourselves some breakfast, watched a bit of TV, fucked on the living room couch, cleaned up the house a bit, fucked again, this time in her room, and by the time our parents came home Shelby had changed into a t-shirt (since her tits were practically bursting out of her tank top) and we had dinner started.

The next couple of days (except Friday, when Shelby had her job interview) went pretty much the same way. Shelby and I would fuck 2-3 times a day, but always have composed ourselves by the time our parents got home. We had to fight to control ourselves over the weekend, since mom and Dean spent most of their time at home getting ready for their trip. When they left for their honeymoon Shelby and I took full advantage of having the house to ourselves. We fucked all over the house. My room, her room, the bathroom, the living room, the den, the kitchen, the backyard, hell, once, because Shelby was feeling particularly naughty we fucked in our parents bed.

We also started getting calls from jobs we’d applied to, and the week after our parents came back, Shelby had a job, and a week later so did I. This of course cut down on our sex life, forcing us to be sneakier, but we always managed to find time to fuck a couple times a week.

Shelby and I had decided that once we made enough money we’d move in together. We presented the idea to our parents as a money saving idea, and to our surprise they had been thinking the same thing. They told us they’d even help us out by helping us look for a place and once we found something, they’d put up half the money for a security deposit.

So now, with our parents help, Shelby and I are looking for a place together. Mom and Dean have no idea they’re helping us look for our own little love nest. In the meantime we’re still having to be careful when we want to fuck, we’ve even managed to do it right under mom and Dean’s noses. Not literally of course, usually once our parents go to sleep. We’ve mastered the art of being quiet, while still having satisfying and intense sex. I can’t wait until we find a place and can go back to having wild passionate sex whenever we want.
