An Unusual Family

The first time I suspected my family was not like every other family was when I was 18. Being a teenage boy, I had all the normal hormones and urges, and I had become fond of masturbating. It wasn't something my family talked about a lot, and I knew that my older sister on occasion played with herself. But it was certainly not discouraged, and to me it was normal to fondle myself in my pants or even out in the open while we were watching television or sitting outside on the patio. In my family, people just did things like that in the open, and no one ever said anything about it. That was how it had always been, and I had even busted my nut in front of my family before. They obviously took notice and would even smile while I groaned and shot a healthy load of cum all over my stomach, but they never said anything bad about it or acted like it was unusual to do that sort of thing in front of them. I somehow knew better than to do it when other people were around, but around my family I was very casual.

My sister Stephie, who was two years older than me, would usually watch me while I did it, and sometimes my Mom would watch for a bit. It was natural for them I suppose to enjoy seeing a penis, especially one that was erect and shooting cum. Stephie would usually stare right at my dick as I would beat it, jerking my dick up and down, up and down, until I would tense up and spew. Sometimes her neck would flush red, or her hand would drift down her stomach towards her thighs. If we were inside the house, a lot of times we would wear as little clothing as possible. Eventually we had become nudists of sorts. We would never go outside naked, but inside the home we would all strip down to nothing and just lounge around that way. If I was lucky, and Stephie was the only one around while I would be masturbating, she would join me and either sit right next to me or right across from me so we could watch each other. We would make small talk or even just stare silently at the other person while they played with themselves, but we never actually spoke about what we were doing. Again, I never thought anything of this, it was completely normal to me. But I would eventually find out just how special our family was.

When I started dating girls from high school, we would do the usual thing of making out or fondling. I remember vividly the girl who opened my eyes to the abnormality of how my family lived. Her name was Liv, and she was a really hot, skinny girl from my Spanish class. I finally had the guts to ask her out, and it turned out that she had liked me all year. After one date of keeping my hands off of her, we ended up kissing pretty heavily from then on. She would even let me feel her breasts while we did it, though they weren't nearly as big as the women in my family. My sister Stephie had pretty decent C cups and my Mom had very motherly D's, despite how slender they both were. Liv was just an A cup, but with her small frame it just made her all the more cute. She would moan so sweetly when I would slide my hand up her shirt and touch her nipples while I sucked on her neck. After a few dates of this, I was ready to move things right along.

Every night after our dates, I would go home and take my clothes off, sit down in front of the television where Stephie would usually be hanging out, and jerk off my throbbing erection until I came in thick heavy spurts all over myself. Stephie would be torn between watching me and the tv. Sometimes she would ask me about my dates, while I masturbated. I enjoyed that, because talking about how we would kiss and touch each other would get me off even faster. And though I didn't know why quite yet, I found myself unusually aroused when my sister would watch me jack off. To me, it wasn't uncommon at all, and I didn't see anything wrong with it. But there was this feeling I had that I would later realize was attraction to my sister. I hadn't been raised to think that incestuous feelings were wrong, though I knew how other people were generally disgusted by incest. Still, I didn't equate masturbating in front of my family as the same thing.

I would soon make the mistake of revealing my naivety to Liv, one night when we were out on the patio at my house. It was not quite dark yet, but we were alone out there sitting together. I couldn't understand why she didn't want to make out like usual. She said she didn't want anyone to see us, but I couldn't figure out why. What difference did it make if my family saw us? I honestly didn't understand. Finally, when it was obvious that for some reason she just would not respond to my touch, I figured I would take care of myself right then and there. She had seen my penis before, and though she had never fully masturbated me, she had fondled it while we were making out. It didn't seem like a big deal to me. But when I unzipped my pants and pulled it out, Liv looked shocked.

"What are you doing, Brian?!" she hissed, glancing around frantically as if someone would see us.

"What?" I asked, grabbing my semi-erect dick and pulling at it.

"You can't do that out here," she said, though I could tell she was aroused seeing my penis. She told me on our last date, after squeezing it and touching it for a good five minutes, that it was the biggest she had ever seen before.

"Why not?" I genuinely didn't understand what she was worried about. I was completely hard now, and slowly jacking myself.

"Your family could come out here any second!" She seemed truly worried, even ashamed for some reason.

"So what? They see me masturbate all the time."

That was pretty much the line that changed everything. Liv's face was a mix of horror and disbelief.

"What the fuck does that mean?" she finally asked.

I stopped beating my meat for a second. "They're not going to care. What's the matter?"

Liv didn't say anything, she just watched me jerking off with her mouth hanging open. Not a minute later, the patio door slid open and my Mom popped her head out.

"Everything okay out here?" she asked.

Liv spun around in terror and stared at my Mom with frightened eyes. Mom frowned, wondering what was wrong, but then she glanced over at me and saw what I was doing. She just smiled and shook her head.

"Brian, that's rude," she scolded in a half hearted tone. Then she went back inside.

Liv turned back to me, and had the strangest expression. "Oh my god, I have to go."

She stood and walked back inside the house.

"Wait, Liv!"

I went after her, my dick still hanging out of my pants. She was already to the front door by the time I made it over to her. She turned finally to let me talk to her, but when she saw my penis still hanging out, she fumed and ended up slamming the door as she left.

"Way to go, Brian," Stephie said from the living room, watching what happened.

"Whatever," I said, and plopped down on the couch next to her.

She eyed my dick, and smiled at me. "Wanna talk about it?"

I sighed, and noticed that my erection came back to life. I grabbed my dick and started masturbating. "Okay, sure."

Chapter 2

That night, I couldn't sleep. I wasn't bothered so much by Liv not wanting to talk to me as I was by the confusion I felt. I couldn't understand why she had been so mad at something so normal. Or at least what I thought was normal. As I was talking about it with Stephie, who had taken her top off while she listened, she didn't say much. I got the feeling she knew something she wasn't telling me, but the closer I got to orgasm, the less I began to worry about it. I had a huge orgasm, despite the rejection I had felt from Liv, and even splattered a bit of my copious load on Stephie's leg. She laughed it off and slipped out of her pants, and we just sat there and finished talking while I wiped my stomach and chest with some tissues.

"You should talk to Mom about it," she finally said, openly sliding her finger between her pussy lips now that she was free of her jeans. "She'll make you feel better."

"Maybe," I replied, watching her finger herself. I was reluctant to approach Mom about this, but later that night when I couldn't sleep, I figured I might as well try.

Dad was working out of state for a few days, so Mom was sleeping alone. I crept into her bedroom at about 2am, still naked since I usually slept that way. I could hear her softly breathing, so I carefully slipped under the covers and cuddled up against her. I used to do this all the time when I was younger. When Dad would leave for work, I would sometimes sleep with her. She enjoyed it, and I enjoyed it too since she always slept naked like me. I loved when she would put her arm around me and her big soft breasts would press against my back, or she would roll over and let me press up against her backside, and my erection would nuzzle warmly against her butt. My young urges often got the best of me, and I would sometimes thrust softly against her while she slept. If she was ever awake while I did it, she never let on. After I would work myself up to a throbbing erection, I would move my penis so it was right between her buttocks and literally fuck her cheeks, gently so as not to wake her, until I couldn't hold back my orgasm anymore. It was the most blissful feeling ever, and in a strange way it made me feel close to her, like we were bonding as mother and son.

I hadn't slept with her in a few years now, but had often thought about whether she missed that as much as I did. She was laying on her side facing away from me, so I sidled up to her and pressed myself against her body. I put my hand on her hip and pulled her against me, though I wasn't quite erect. I just wanted to feel her warm body close to mine. My hand drifted up her side and rested just below her breast, and I hugged her tightly. She moaned softly in her sleep, and I felt her ass move against me. She was instinctively trying to feel for my erection, or maybe my Dad's I guess. I was instantly rock hard when I felt that, and almost like we had never stopped doing this, I found my body moving right into place. My penis was between her buttocks, and my hand groped at her breast before I knew what I was doing.

"Mmm," Mom sighed, stirring a bit. "Brian?"

I was surprised she knew it was me. "I was having trouble sleeping."

She smiled, her eyes still closed. She was only half awake. "I used to love when you came to sleep with me."

"I miss doing it." I thrust my hips forward unintentionally, grinding my hard dick into her ass.

She moaned. "You always used to make such a mess of me."

Oh my god, I thought. Did she really just say that? So she must have known what I had been doing all those nights. I suppose it was foolish to think she wouldn't, considering the "mess" I would make.

"I won't make a mess this time, I promise," I whispered, a bit embarrassed. Still, it was not the scandalous act in my mind that it probably was to the rest of the world.

"I don't mind," she said sleepily. "If you need some relief, I'm always here for you."

Wow, that was such an arousing statement that I almost came right then and there. I gritted my teeth, feeling the pleasurable tinglings in my balls as they tightened up. I held it back for now, but I was glad to know that she would let me get off with her before I left. I would probably need it.

"I was hoping we could talk, if you're not too tired," I said.

Her eyes opened finally. "Sure, honey. What's the matter?"

"It's Liv," I said.

I moved back a bit while Mom turned over to face me. It was rare that we had ever slept facing each other, but at the moment it was very exciting to see her naked like this. She was gorgeous for a woman her age. Her breasts looked amazing, even in the dim moonlight from the window. Her beautiful eyes were looking right into mine, and she showed nothing but motherly concern as she faced me and scooted closer so that our bodies were touching once again. She stroked my face with her fingers, and my penis pressed right against her stomach. I was nearly trembling with arousal, and I knew I was leaking precum onto her. She did absolutely nothing to show that she noticed.

"Is it about earlier?" she said.

I nodded, but I was looking down at her breasts. She moved up just a bit to give me a better view of them, but she stayed on subject.

"It's partially my fault," she said, with a sad expression.

I frowned. "What do you mean? How could it be your fault?"

She sighed, and her fingers drifted down from my face to my neck and chest. "I've always kept you a bit sheltered. I always loved how close you and I were, and I didn't want to spoil anything between us."

"What does that have to do with anything?" I was confused, but partly because my aching erection was twitching against Mom's stomach.

"Most families aren't like ours, Brian. They're not close, they don't talk to each other, and they certainly don't do...'things' with each other like we do. And I didn't want our family to be like that, I wanted us to be close. Your Dad feels the same way. He grew up in a divided family, and all of his siblings fought with each other and grew up to hate each other. I never had siblings, and my parents were very repressed from the way they grew up. When we got married and I was pregnant with your sister, we decided that we would do our best to raise our children in a loving, open and honest home. I think we've done a pretty good job of that."

"I do too, Mom." Her fingers trailed down even further from my chest to my stomach, tracing around my belly button.

"But it's my fault that I didn't do much to warn you about how other families are."

I shook my head. "It's not your fault."

Her fingers grazed through the trail of hair from my belly button down to my groin, and her fingertips just barely touched the root of my shaft.

"I thought maybe as you got older, you would start to understand other families more. Your sister was quick to pick up on it, and she learned early on that she couldn't tell anyone about the things we do differently."

"She never said anything to me about it." I clenched my teeth as Mom's fingers drifted down my thigh and moved underneath my balls, her knuckles gently bumping against them.

"Did she leave you frustrated?" Mom asked, referring to Liv. Her eyes reflecting a look of motherly love and worry.

I nodded. I didn't mention that I unloaded with Stephie right after Liv stormed out. But I was far more aroused and excited now than I had been back then.

To my surprise, Mom leaned forward and kissed me on the lips. It wasn't a deep kiss, but it was very intense for me. I kissed her back, and when I parted my mouth to snake my tongue out, I found hers already on its way into my mouth. In one giant sensation of sexual pleasure, I thrust myself against her, and her fingers wrapped sensually around my penis and squeezed softly. We kissed somewhat passionately, but I was fully submitting to her now like an obedient child. With her tongue in my mouth and her hand jerking me off gently, I came with such force that it took my breath away. I grunted and groaned into her, weakly thrusting my hips forward while she firmly held onto me, milking me of semen and pleasure as I twitched and shook, all the while still kissing me. I whimpered as she pulled her face away finally, but kept my penis in her loving grasp. She slid her thumb under the head of my dick and stimulated me in that sensitive spot, literally coaxing another jet of sperm from my balls. The experience was just as emotional as it was sexual, and I couldn't have felt more love for my mother.

"Mmm, good boy," she purred, kissing my forehead. "Does that feel better now?"

I nodded, but my breathing was too ragged to speak. She lightly ran her hand along the length of my shaft, and I looked down to see what a mess I had made of us both. There was cum everywhere, but neither of us cared.

"Don't worry about Liv," Mom said, laying on her back but turning her head to smile at me. "I know her parents, and they're good people. If she says anything to them, and they call to talk to me or your father, we'll smooth things over."

We just laid there for a while, Mom gently stroking my slimy erection while I pawed at her breasts. There was something so innocently arousing about the situation, I couldn't see why anyone would see anything wrong with this.

"Mom?" I asked, after a few minutes.

She had closed her eyes, but opened them again and looked over at me.

"Would it be wrong for us to have sex?" I said boldly. I suppose I shouldn't have been greedy, but I felt so much love for her that I had to know how far she would allow things to go so I wouldn't betray her trust. And even though I had just came spectacularly, I was still really horny laying next to her naked while we touched each others' bodies. And of course, I had never had sex with a woman before.

Mom allowed a smile to creep at the corner of her mouth. "You're still not satisfied, huh?"

I shrugged, but my hand dropped from her breast and slid down her body past her stomach and towards her crotch. Her reply had told me pretty much everything I needed to know, at least at the moment.

"I just want to be inside of you," I said. But when my fingers felt her small patch of pubic hair, which she regularly shaved, she stopped me.

She looked at me seriously. "Just hold me. For now."

I was disappointed, but wasn't about to protest. I loved her, after all, and would never do anything to hurt her. She rolled into me and we embraced. Her leg wrapped around my hip and pulled me into her. I could feel her nipples poking me, and my penis slid down between her legs to rest against her crotch. When I felt her pubic hair against the top of my shaft, I was surprised that she allowed me so close to her vagina. It was practically mashed against the top of my dick. Mom kissed me again, and then nuzzled her face into my neck. I thought we would just go to sleep like that, but after a few peaceful moments, her hand reached down to grasp my penis.

She smiled. "You're so big."

I got hard quickly after hearing her say that. When I was at full mast again, she moved the tip so that it was resting against her pussy lips. I was so shocked I didn't say or do anything. I let her be in full control. She gently rubbed the tip of my cock against her pussy, moaning as she basically masturbated herself. I could have let her do that all night, but after a few minutes of playing, she split her lips open and began to feed my thick cock into her body. I couldn't believe this was happening! We were actually having sex, or at least something like it. Mom didn't have any trouble taking my size, and after a minute of soft thrusting, I was buried all the way inside her pussy.

I surged with love for her, and felt so powerful now. I wanted to grabbed her wrists, throw her back onto the bed, and fuck the shit out of her right then and there. But instead, we held each other tight and just laid there like that. Her vagina clutched at me, her muscles literally milking my cock inside of her. I didn't move much, just an occasional involuntary thrust as she carefully and methodically worked her pussy on me. But we never left our embrace, and it never became heated. It was a simple, gentle, loving act. Still, the excitement of it all was getting to me.

"I'm going to cum soon," I said, warning her well ahead of the explosion.

She didn't say anything, she just kept her face nuzzled into me and worked me over with her pussy. Soon I could hear her breath quicken, and she started making little grunts and noises that told me she was getting off. As I felt her pussy clamp down and quiver in climax, I couldn't hold back my thrusts as my cock exploded inside of her. The room seemed to be spinning and my vision went blurry. My body was on fire as my penis began firing off endless jets of thick white fluid into my mother's vagina, filling her up and claiming her body with my seed. She cried out as her pussy submitted to my pounding, accepting everything I could give her. I could feel her meaty lips mashed against my pelvis as I crushed my body against hers, our pubic hair tangling together in a slimy mess of our fluids. She was making so much noise I was sure Stephie would hear us. Her guttural moans were broken by the force of my thrusts, until finally she was an exhausted and sexually dominated animal, curled up in my arms.

either of us said anything before we drifted off to sleep. I stayed in her bed the rest of the night, feeling that our relationship had grown immensely. But there was still a lingering feeling of confusion about how to deal with people outside our family. Surely there had to be others like us, who showed the same kind of love to each other. I awoke early in the morning, only a few hours after our sex, and Mom was quietly nursing on my penis. I had never had a blowjob before, since I had been a virgin until last night. I was amazed at the incredible sensations her lips and tongue were giving me. She sucked my dick softly and wetly, rubbing my balls and even below them in a place I never knew could feel so good, and when she began jacking my shaft while her mouth sucked on the head, I moaned loud enough to let her know that I was cumming. She pulled her mouth back just far enough that my sperm could shoot out onto my stomach, and her tongue darted all around the tip while I came. She seemed to enjoy watching me cum, as I had always suspected when I would masturbate around her and she would often smile when I unloaded all over myself.

"Oh god," I sighed. "That was incredible!"

Mom smiled brightly as she continued to suck on me until there was no more cum for her to taste. She licked her way up my body, snaking her way through the cum trails until she was resting next to me, her arm across my chest.

"Thank you, for last night," she said.

"I love you, Mom."

She kissed my arm, and we both waited a while before getting up. She didn't want Stephie to feel awkward if she knew we had slept together, but I was certain that after last night she would be fully aware that something sexual had happened between me and Mom. Still, I only wanted Mom to be happy, so I quietly crept out of her room and back to mine. I laid on my own bed for a while, replaying last night in my head and remembering my first real sex. I wondered if she would tell Dad, though I wasn't scared of him by any means. It sounded like he would feel similarly about sex between family members, from what she had told me.

The next time I saw Liv at school, I could tell things were awkward. But she didn't try to avoid me, which I was thankful for. I apologized to her, and promised that I would be a gentleman around her if she wanted to keep going out with me. I didn't even touch the subject of masturbating in front of my family, which she was probably thankful for. It was still strange to her, I could tell. But I was surprised at how well she was taking it.

"I overreacted," she admitted, as we stood off in a corner where no one would see or hear us.

"I guess I was just horny or something," I said, making her smile. "I just really think you're cute."

"I have been teasing you, I guess." She looked up at me sheepishly. "I've just been afraid because your cock is so big."

I had to fight against the erection forming in my pants. "I can't help that, sorry."

She giggled, but then turned more serious. "I'm not sure how to talk about this, but do you really...you know, jerk off...in front of your family?"

I felt really uncomfortable, especially after what Mom told me last night about other families and how they viewed that sort of thing. But I wanted her to like me for who I was.

"It's not like that," I said. "We're just really open about that kind of thing."

Liv seemed interested, but quiet. After an awkward moment, she spoke up. "Are you guys nudists?"

I shrugged. "Something like that. Not around other people though."

She nodded, thinking it over deeply.

"Why?" I asked. "Does that bother you?"

"No, I'm fine with that," she said. "Actually, I know some people who are into that kind of thing."

We had to stop talking while some kids walked past. Afterward, Liv leaned close to me and kissed me.

"I was just surprised by it all," she said, "and that's why I left. But seriously, I am dying to know what that thing feels like inside of me."

I groaned with arousal at hearing that, and we kissed again. "Come by again then."

"When?" she asked. "Your family is always around."

"They won't bother us," I assured her. Then I took a real chance. "Doesn't it excite you when other people know what you're doing? Even watching you?"

That was a big gamble, but Liv didn't recoil in disgust. She just looked at me, biting her lip.

"I've never done that kind of thing before," she whispered. "I just don't know."

The bell rang, and we had to go separate ways. I just smiled at her.

"Think about it, and come by if you want."

She was silent as I walked away, and I had a feeling that she would never come over to my house again. But I had to be honest with her about myself. I couldn't lie to her or hide a part of my life that I loved. I couldn't wait to get home later and talk to Stephie about it.

Chapter 3

"So what are you gonna do?" Stephie said, her legs spread wide and her bare pussy clearly visible to me.

"I don't know," I replied, stroking my dick in front of my sister. She wasn't masturbating herself, just letting me get an eyeful while I jerked off.

"Imagine she was here right now then," she said, completely serious. "What do you think her reaction would be?"

I just stared at my sister for a moment, taking in the sight of her gorgeous body. I had to admit that I was probably more attracted to her than I was to Liv.

"God you're hot," I said after a while, ignoring her question.

Stephie was surprised to hear me say that, since I had never spoken to her in a sexual manner before. She was obviously flattered, though. Something in me wanted to take advantage of this situation.

"She told me once that she really gets off on oral," I said, breaking the silence. "And she likes watching someone get it, too."

Stephie kept her legs open, and her smile told me that she was playing along. "Really?"

I nodded, less involved in my own pleasure now. "We haven't done it yet, but I am dying to eat a pussy finally."

"You've never done that?" Stephie said, truly surprised. "Wow, I can't believe it."

"Does it feel good?" I asked, moving the conversation in the direction I was hoping it could go.

She nodded enthusiastically. "It feels so good, a lot of girls get off on that more than fucking."

Hearing her swear made my dick lurch. She made that word sound so dirty and sexy. "What about you?"

She knew where I was going with this, I was sure of it. "I love oral sex. Receiving and giving."

She caught me off guard with that, and I had to slow down my pace otherwise I might cum before we could play around with each other.

"Your pussy looks really nice," I said. "I bet it tastes good."

Stephie scooted forward on the sofa across from me, and pulled her ankles behind her head. I never knew she was so flexible. That pose opened up her pussy completely, and I could almost see inside of it.

"Do you wanna see what it's like?" she asked nervously, despite her obscene posture.

I stopped jerking and just sat there. "Really? Are you sure?"

She nodded, her eyes sparkling with excitement. "I would really love that."

I couldn't believe I was going to have my mother and my sister all within a 24 hour period. I got off my ass and knelt in front of Stephie. My mouth was watering as I approached her beautiful cunt.

"I'll do you after, too," she said. "If you want."

I was so turned on I didn't even know what to say. I just inched my face closer to her beautiful thighs and started kissing all around her crotch. I purposely avoided direct contact with her pussy for a good minute, teasing her and making her giggle. She smelled so good, I was getting dizzy from her sweet scent. Her pussy was oozing by the time I closed in on it with my lips, and I gave her a firm, broad lick with my tongue. She gasped, but kept her body still for me. I even loved the way her asshole looked, and dared to dart my tongue down to it a few times before really digging into her sweet wet flesh. She never objected to anything I did, and I just kept lapping at her and sucking on her clit while she moaned and her pussy convulsed. I had seen a lot of internet porn, so I knew somewhat how to eat a pussy. I think I could have been the worst pussy eater in the world at this moment, and still made my sister cum.

"Oh god, Brian," she gasped. "I'm cumming!"

I kept assaulting her clit with lashes of my tongue, and a bit of extra fluid oozed out of her pussy why she climaxed in my face. I buried my mouth in her and just kept sucking on her, driving her crazy until she was out of breath. I backed off a bit, and she just smiled down at me.

"You're good at that," she said, her chest heaving.

I trailed my tongue back down to her sphincter, and her smile turned into an expression of pure lust and arousal, her jaw jutting out slightly as she groaned at the forbidden touch. Her asshole didn't taste at all like I imagined it would, it was just like the rest of her skin. The tight opening gripping my tongue was exciting as I tried to penetrate her, but she was so tight I would need something much firmer than my tongue.

"I've never had that done before," she said, her head falling back and her eyes closing in pleasure. "It's really nice."

"It really makes me horny," I said, going from her ass to her pussy and back.

"Do you want to fuck me?" Stephie asked. "Or do you want a blowjob?"

I felt so lucky to have such a hard decision to make. I couldn't believe she was so open to having sex with me. Maybe she had felt the same way about me all this time as I had felt about her.

"Imagine Liv was here," I said, referring to her earlier question. "Which would you prefer to show her first?"

She loved that I was playing on her scenario from before, and literally pushed me back onto the couch. "She's going to want to know how to blow a cock as big as yours, I bet."

For the next three minutes, I was in heaven. My sister really knows how to suck a dick, I discovered. She gave my balls a quick licking and sucking, and then took my meat straight down her throat. I discovered how good deepthroating felt, and when she started to play with my balls and ass, I could feel my resolve giving in. At first I wanted to show off how long I could last, but now I wanted her to know how wonderful she was doing, and how good it made me feel. I had already been masturbating too, so I was about to blow. I didn't even warn her that I was cumming, I could tell by her skills that she was a true cocksucker, and would gladly eat my cum. I forced myself not to thrust into her face, and fought off my orgasm as long as I possibly could before it burst forth and erupted from my body.

Stephie groaned as she felt the first ejaculation hit the back of her throat, and she kept eagerly sucking at me while I continued to blast her with sperm. I couldn't move for a good long minute afterward, as she leaned back and smiled at me, quite happy with herself. There was cum smeared across her mouth and chin, but she looked absolutely gorgeous like that.

"Wow," I said, my dick twitching and bouncing. "That was incredible."

"I can't believe we never did this before," Stephie said, leaning forward again and softly licking at my shaft.

"I didn't know you would want to," I said, staying immobile while she continued playing with me.

"I've wanted to for a long time," she admitted. "But I guess after last night when I heard you and Mom, I decided I would finally go for it."

I turned red, somehow embarrassed despite what had just happened between us. "God, I was hoping you didn't hear that."

"No, don't be mad," she said, frowning. "I think it's sweet. Mom gets lonely when Dad leaves. I've slept with her on rare occasion, but she really needs a man's body to make her feel good."

I was surprised. "You slept with her too?"

"Sure. But we never fooled around like you guys. Once we masturbated together when she had a hard time falling asleep. But that was it."

"Wow, that is so hot!"

"Really?" Stephie seemed surprised that I would find that arousing. "Huh, I guess I thought with all the masturbating that goes on around here, you wouldn't really care too much about that."

"No way, I think that's really sexy. Next time, let me watch."

She laughed, and we heard a car door shut in the garage. Mom was home. Stephie looked at me awkwardly, not sure if she wanted Mom to see us like this.

"Should I hide?" I asked, not wanting her to be uncomfortable in front of Mom.

"Um, it's fine." She was hesitating. "I just...I don't want Mom to feel weird about it. Since you two are...uh, you know..."

I laughed. "It's not like we're dating."

Mom came in from the garage, carrying grocery bags. I jumped up to help her, and she just smiled at us. She didn't seem to notice, or at least make it known that she noticed, how suspicious we might have looked. Especially with cum all over Stephie's face.

"Thanks, dear," she said. "How did things go with Liv?"

I honestly forgot about her for the last little while. "Oh, well, I think things might be okay now. I don't know if she still wants to date me, but she's not mad anymore. I don't think she really was."

I helped Mom with the rest of the groceries, and thankfully she had already closed the garage door since I was totally naked. Stephie had disappeared, probably to clean herself up from our playing around.

"So did you explain things to her?" Mom asked, still interested in Liv. "About our family?"

I shrugged. "I didn't really go into it, but I think she knows that we're different. I hope she's okay with it, but if not then it's probably good that we don't keep dating."

Mom glanced down at my dangling penis, and smiled at me. "It would be nice if she would understand. There are so few people like us. Every time we can help someone to appreciate us, we have to do everything we can to hang onto those people as friends."

"Yeah, that would be great."

"I'm glad you think so. Now that you're of age, I think you might be ready for our special family parties."

I raised an eyebrow. "Huh?"

Mom smiled, and started putting the groceries away. "Usually about once a month, there's a family a few towns over that hosts parties for families with children 18 years old and up."

"Why is it adults only?" I asked, though perhaps I was answering my own question.

Mom just smiled. "It's a nudist party."

My eyes shot open. I didn't Mom and Dad did that outside of our house. "Really? That's pretty cool."

"Glad you think so. We took Stephie last year, but made her promise not to tell you. We weren't sure if you were ready for that."

"What happens at these parties?" I was curious now, and my penis was starting to stiffen. Mom noticed.

"There's no sex, if that's what you're asking." She gave me a funny expression. "At least in front of anyone."

"I guess I just meant, what does everyone do? Just sit around naked?"

"It's a party. We talk and laugh and have fun. The Christiansen's have a pool."

"Christiansen?" I asked, surprised. "Mark and Jennifer?"

"Yes, they were the first nudists in our group."

I couldn't believe that tight-ass family were nudists. They had kids, though I think one was married by now.

"How many people go to these things?"

Mom thought for a moment. "Maybe twenty? I don't know, it's a lot. Some come from out of state even. There's not many nudist events around here."

"And no one calls the cops on you guys?"

Mom laughed. "Mark is a senator, dear. I think the cops know not to interfere. And they never have. But that's why we don't allow anyone under 18 to attend. Just so there's no legal trouble."

Interesting, I thought. I knew he was a connected man, so I shouldn't be surprised that he was into some weird stuff. Of course, to me it wasn't that weird, it was a normal part of our family. But I didn't think other families would be like ours. I was actually excited to go, now. The Christiansens had some really hot daughters.

"What about the guys?" I asked. "What happens if they...you know..."

Mom was busy rummaging around the kitchen, but she didn't bat an eyelash. "If they get an erection?"

I nodded. "Yeah."

She shrugged. "After you've been to a few, it's no big deal anymore. But if it happens, it's polite not to stare or talk about it."

Whew, so if I got one, they wouldn't kick me out. That's all I needed to know.

"When is the next one?" I asked eagerly.

"Next week, Friday night. Keep it open, okay?" She winked at me.

I would definitely do that, I didn't want to miss this!

Chapter 4

The next night, I couldn't sleep at all. I was too excited about this upcoming nudist party Mom had been talking about. Dad was gone for one more night, so I started down the hallway towards Mom's bedroom. I passed by my sister Stephie's room, and my naked penis started to get hard, as if it was telling me something. I had planned on getting off with Mom, but then again, Stephie and me were now progressing to the same level of our relationship. Why not have both?

I opened her door quietly, not wanting to wake her. She was sleeping soundly in her bed, tucked under her blankets and breathing gently. I closed her door behind me as I entered, and crept up to the side of her bed. I started jerking myself as I watched her sleep, admiring how beautiful she looked. I was really getting horny being here with my sister. I had always secretly thought she was sexy, and loved when we'd have our masturbation sessions while we chatted about stuff. I hadn't really appreciated how much my infatuation for her had grown recently, but right now I was almost as horny for her as I had been for Mom the night we had sex.

Stephie must have heard me beating my meat, and her eyes blinked open. She struggled to see in the dark what was going on.

"Brian?" She sounded so tired, I worried that I might be bothering her.

"I couldn't sleep," I whispered, still wanking.

After a moment of comprehending what that had to do with my presence here, a huge smile came across her face and she pulled her covers back, revealing her wonderful naked body.

"Come join me then," she said excitedly, motioning for me to get under the blankets with her.

I climbed in, though her bed was just a twin and there was no way we could lay next to each other. She wasn't moving anyway, so it was obvious she intended for me to lay on top of her. I almost laughed at how obvious she was being, but I knew she would let me fuck her if I asked her. It appeared that asking wasn't necessary. She covered both of us with her blankets, and spread her legs underneath me so that I could lay comfortably with our bodies lined up together, my big penis resting on her stomach. My balls rested right on her pussy, which was perfectly smooth and bare.

"This is nice," she said, enjoying the warmth between us.

"Yeah, I'm glad you're not upset that I woke you up," I replied.

She put her arms around my back and just smiled up at me, our eyes locked on each other.

"You were masturbating while you watched me," she said, alluding to moments earlier. "Did you need some help with that?"

I didn't bother to answer, instead I lowered my face to hers and kissed her very wetly and very passionately. She moaned when we kissed for that first time, her body responding to my movements. Her hips began to thrust up at me, and I was grinding my cock into her pelvis. We dry humped for a few minutes while we groped each other and sucked at each others' mouths. I couldn't believe how frisky my own sister was for me, and it made me feel really good that I would have a fuck buddy when Dad came back and I couldn't sleep with Mom anymore.

Finally, I couldn't take it anymore and I just had to taste her pussy again. The other day when we had traded oral favors, I couldn't believe how sweet she had tasted. This time was no different, her pussy was still intoxicating and fresh. I smeared my tongue and mouth all over her cunt, sucking on her clit and penetrating her with my tongue as far as I could stick it. When I let my index finger trail down her inner thigh and graze her ass cheek, she bucked underneath me. I took that as a good sign, and I began to explore her ass with my finger. I trailed along her crack, and slowly moved inward to her sphincter, and she began making the most wonderful sounds. I was still eating her out madly, but finally I worked my finger into her tight butthole and just held it there while she convulsed and cried out, climaxing hard in my mouth. I removed my finger, but moved my tongue lower to lick her where I had just penetrated, making her purr. I could lick her pussy and ass all night, they tasted so good.

hen I finally moved up and positioned my aching erection at her oozing hole, Stephie eagerly thrust at me, trying to get me inside of her. I didn't hesitate, I plunged right in and took her with one thrust. Her jaw dropped open, and she just laid there tensed up, feeling the pleasure that came from me claiming her pussy. I held myself deep inside of her, noticing how much tighter she was than Mom. I was going to enjoy this.

For nearly an hour, we just fucked and fucked. I thought she would get sore or tired after a while, but just when I thought I felt her begin to slow down, her pussy would start to quiver and she would cum in violent waves, clawing at my back and holding me tight with her legs. When she finally climbed on top of me, and let me grope at her tits while she rode me, I came forcefully inside of her, filling her cunt with my semen. I loved feeling her tight sheath caressing me while I emptied myself into her. It was so intense and forbidden, I thought she was going to drive me insane when she began riding me again, not satisfied with what I had given her.

"Wait," I said, five minutes into our second fuck.

She looked disappointed, but I had a delicious idea.

"Get on your knees," I ordered.

She smiled, and with a renewed burst of energy, buried her face in her pillow and lifted her ass in the air. She reached her hands back and spread her butt for me in an obscene display. I grabbed her hips and lowered my mouth onto her ass, licking her little pucker hole with firm, wet lashes. She was going crazy as I ate her ass out, getting it nice and wet for what was about to come. She wasn't hesitant at all, making me wonder if she had done this before. It didn't matter, I was going to fuck her ass regardless of the lack of experience from either of us.

My dick was slimy with her pussy juice, and combined with my saliva, I was able to push my head right against her anus and slide a few inches in. She groaned loudly, and I waited for her to calm down a bit before going further. It was hard to wait, though, with her tight little asshole clenching at my dick. I put one hand on her shoulder and held her hip with my other hand, and very carefully slid my big cock up into my sister's butt. I didn't stop this time until I was all the way in.

Stephie was practically in tears, but not from pain. This was so intense, she was loving it as much as I was. The whole scenario, being butt fucked by her brother, was enough of an arousal to counteract any discomfort. I never would have thought that anal sex could really happen just like in porn, without lots of preparation and slow stretching.

"You've done this before," I said.

She just nodded, much too involved now to speak. That just emboldened me to keep going strong. I pulled out of her ass a few inches, and then plowed right back in. Every time I thrust into her, she grunted loudly. Eventually it became a weak moan as I made her cum like that multiple times, each time making her pussy squirt from the intensity. She had completely soiled her sheets by the time I was close to my own orgasm, and I had to decide between cumming inside of her or pulling out and spraying her backside. Eventually my instincts won over, and I groaned deeply as I buried my dick in her ass and let my cum spew forth, filling her bowels with my seed.

With my dick still inside of her, we both just laid there panting. It took a few minutes to recover from our sex, and Stephie was a sweaty mess. I stayed hard inside of her butt, though I knew I should pull out and let her relax. My dick slid right out, and her anus looked so stretched and abused that my dick lurched and twitched at the sight. After a while, Stephie crawled over to me and we embraced weakly, drifting off to sleep amidst the pungent smell of sex and sweat. It was the most satisfying experience of my young life.

Chapter 5

Liv came over the next day, after I had gone the entire day at school without seeing her. I was honestly surprised she came over to my house, but I worried that she felt she needed to break up with me here rather than at school. That would explain why she avoided me all day.

But to my delight, she was not breaking up with me.

"I love being with you," she said, as we sat out back on the patio. I was on my best behavior, unlike last time.

"I love being with you too," I said. "But I'm very sexual, and I don't know if I can keep myself from expressing that when we're together. Even if it's in front of my family."

She nodded, carefully considering that. She knew I jacked off in front of my family, but she didn't know that I had fucked both my sister and my mother. That would come in time, if we continued dating for that long.

"I thought a lot about that," she said, fidgeting in her seat. "I guess part of me just can't get used to it, until I see it."

What exactly was she saying? My face must have shown my confusion.

"I'm kind of interested in seeing you do...that," she continued. "In front of your family. It turns me on to think about how open you all are."

I was starting to get hard, but I resisted the urge to whip it out and start beating off. If it was just me and my sister, then I definitely would have.

"You want me to call my Mom over?" I laughed.

She smiled, still a bit nervous. "No, no. I just mean, I want to hang out more with you. Here. And if you guys are naked, and you masturbate, then that's fine. I'm very curious about it all."

I kissed her, very grateful that she was so accepting of this. My Mom was right, if we found someone to share our lifestyle with, then we had to hang on to them. Friends like that were rare.

"You said you had friends that were nudists," I said, referring to something she had said last time we talked.

"The Christiansens," Liv nodded. "I'm friends with one of their daughters. Becca."

Christiansens! They were the nudist family that was hosting the party on Friday. And Becca was really hot, I had beat off to the image of her sucking on my dick many times. I had even told Stephie once while I was masturbating next to her that I was thinking of that. She had been very intrigued, and dare I say aroused when I shot off a nice big load a few moments later.

"We're going to their house for a nudist party on Friday," I said. "Have you ever been to one of those?"

Liv shook her head. "No, but I knew they had them. Becca talks about them, and how there's no young guys that go to them. If you're going, I may have to keep an eye on her."

Now I was really excited to go, since it sounded like I would be the only young guy there.

Liv and I talked about it for a while, and then she had to go home. I walked her to the door and kissed her goodbye, and when she was gone and I closed the door, Stephie appeared behind me.

"How'd it go?" she asked, perhaps anticipating that I would want to talk to her about my relationship problems again, which generally meant she would see me jerk off.

"Great," I said, not oblivious to her desires. "She sounds like she might want to hang out with us more."

Stephie seemed interested. "Really? She's not grossed out by what we do?"

I shook my head. "I think it's starting to turn her on. And it turned me on a lot hearing her talk about it."

She smiled, and cocked her head a bit. "Do you need me to suck your dick? To relieve the pressure?"

I swallowed nervously. She had never been so forward, though after last night, there were certainly no inhibitions between us anymore. I just nodded dumbly.

"Let's go upstairs," she said, taking my hand and leading me to my room.

Dad came home a few minutes later. I heard him downstairs while Stephie was deepthroating me. Her chin was resting against my balls, and her saliva was dripping down them. I held her head firmly against me, literally mashing her against my crotch. I fucked her throat slowly, probably choking her a bit. She never made a sound or complained, she held herself down on my dick obediently. I finally let her off, and she excitedly gasped for air and went for my balls, licking and sucking on them while I jerked my cock over her face. I came heavily onto her forehead and nose, coating her lovely features with my thick cum. She moaned in appreciation, enjoying the warm feeling of my fluids painting her skin. Her mouth found its way back onto my dick and she sucked on me for a good few minutes afterward, while I leaned back and enjoyed the relaxing sensations. God, I loved her.

After cleaning her face up, we both went downstairs completely naked and greeted our father. Mom was making a nice big dinner which smelled great, and for some reason my Dad smiled really big when he saw me. He slapped me on the shoulder like he was congratulating me for something, but he never said what. He just acted genuinely happy. Mom just winked at me when I looked over at her, and I figured she had already informed him of the latest sexual developments in our house. I think she knew Stephie had been upstairs sucking my dick.

After dinner, I noticed Mom excused herself. I knew she was going to change into my Dad's favorite sexy robe of hers, just like she always did when he came home after being away. I felt genuinely happy for him that he was going to get really laid tonight, I wasn't jealous like I thought I might be. But I did have a delicious idea.

I went upstairs to my parents' bathroom and found the door wide open, and my mother pulling her robe over her shoulders. She saw me in the mirror and smiled.

"Don't get any ideas," she said. "I've been doing Kegels all day to get my pussy tight for your father, and I don't want it all stretched out by your big cock."

I just shrugged. "I don't have to stretch your pussy, I can stretch something else."

She raised an eyebrow. "You've been playing with Stephie, haven't you?"

I nodded. "Have you ever done it?"

Mom turned and faced me, her robe totally open in the front exposing her gorgeous naked body. "Go get the lube from my drawer."

I excitedly ran to her nightstand and fetched the bottle of lube, which was almost empty. Were Mom and Dad freaky? Good for you Dad, I thought.

Mom had turned back around and was leaning forward over the sink, and had drawn her robe aside to expose her backside. When she spread her ass cheeks for me, I thought I was going to die. I could tell her tight little butthole was used to being penetrated, but it still looked exquisitely small and delicious. I smeared the lube around my dick and approached her with shaking hands.

"You can enjoy it," she said, smiling back at me, "but do try to hurry. I'll swear a lot for you if you like."

I simply nodded, and positioned my aching penis at her forbidden entrance. I pushed the head up against her pucker, and gently pushed. Her sphincter gave way almost immediately, and she moaned in pleasure. She liked having her ass stuffed! I wish I had known that when I was younger, although I probably never thought about anal sex until I discovered porn. Still, hot-dogging her when I was a kid didn't come close to this experience.

I slid further in, beginning to claim her butt with my thick shaft. As I gently fed it into her, Mom just grunted sexily and would quietly say "fuck" and whisper things like "oh yeah, do me in my naughty butt Brian" while I tried to hold back from thrusting too hard. I wanted to enjoy the feeling of her experienced asshole gripping and tugging at my dick.

"Does Stephie fuck Dad?" I blurted out while I began to thrust with more power, getting a fuck-motion going.

Mom laughed. "Are you jealous, after all you get to do with both of us girls?"

I wasn't jealous, just curious. "Just tell me."

She took a few moments to savor the feeling of her son filling her tight rectum with cock meat before answering.

"They have never had sex," she said finally, surprising me.

"Why not?" I was really getting into it now, and could feel an orgasm building even though Stephie had drained me quite expertly before dinner.

"Stephie wanted to do you first," she replied, and I could feel her legs quivering. She was going to cum just from having her butt fucked.

I let her enjoy it without saying anything more, feeling her body tighten and her ass clench impossibly hard on my dick as she squirted on the bathroom floor. She groaned loudly as she came, and with such force that I couldn't help but cum myself as her ass clamped down on me. I poured myself out into her bowels, filling her back door with my sperm. I had claimed both her holes now, squirting my cum deep into her like very few sons got to do, I imagined.

"Is that true?" I said with ragged breath.

Mom nodded, rubbing her pussy in the afterglow of her climax. "Your father is so busy, and I keep him pretty well fucked."

"I can imagine," I said, smacking her ass and withdrawing from her tight little butt. My cum dripped out, and Mom wiped at it with some tissue until it stopped leaking. I enjoyed watching her clean up after our naughty act. She just smiled lovingly at me when our eyes met.

"Stephie is a lucky girl," Mom said, and kissed me quickly on the lips before heading back downstairs.

Chapter 6

Liv texted me that night and asked if she could come over late and fool around with me. I wanted so badly to see how open she would be to including my sister, but I didn't dare say anything before she was actually here. Mom and Dad were already in bed, and Stephie and I were downstairs watching tv. We actually weren't fooling around for once, since I was exhausted and she seemed satisfied with what we had done together earlier. When I told her that Liv was coming over, and her intentions were sexual, Stephie was visibly excited.

"What do you want me to do?" she asked. "Want me to leave you two alone for a while, and then just walk in on you? Or should I just hang out here naked and see what she does?"

I laughed at her excitement. "Let's just see what happens. She's probably horny so I'm sure if things are relaxed enough, she'll want me to start masturbating in front of you."

Stephie rubbed her crotch through her pajama pants at the thought. "I can't wait! Do I pretend I don't notice you? Or do I smile and make it seem normal?"

"Make it 'seem' normal? Isn't it?"

"You know what I mean. It won't be to her, and I know more about how other people perceive this kind of thing than you."

"True, I guess just do whatever you think will help the situation more."

She clapped her hands together. "Ok!"

After about a half hour, there was a soft tap on our front door, and Stephie literally leapt from the sofa to answer it.

"Hi, Liv!" Stephie greeted a little too loudly. Even if she woke our parents, they wouldn't care. They were probably so exhausted that they didn't hear anything anyway.

Liv stepped inside, a bit awkward in front of my sister. "Hi, Stephie right?"

Stephie nodded, grinning from ear to ear. "Yep, come in. We're just watching tv."

I stood up and gave Liv a small kiss and hug, and she sat down with us. I felt oddly excited as well, as if something big and important was going to happen if everything played out the way Stephie and I hoped. Not just in a sexual way, but more important. Mom's words about finding people who accept us, and hanging onto them, suddenly flashed in my head. I really wanted Liv to accept us, and we had to play it cool for that to happen. If I just whipped my dick out and started beating off, it would be blatantly about the sex and not the overall relationship that our family had cultivated. Liv had to come to appreciate that we were normal in every other sense, and that our open sexuality was the only thing that would come as a shock to people. She could still feel comfortable and enjoy just hanging out here at our house. We didn't have to do anything else, unless she wanted to.

Liv and I cuddled close while Stephie sat on the other couch, not crowding in on our personal space like I figured she would. But she was genius, because from this angle Liv would be able to see her without staring right at her, and if she started taking her clothes off or touching herself, Liv could pretend she wasn't watching even if she was. My sister was pretty smart, I had to give her credit.

"Let's watch something else," Stephie said after a while. She found some rated R movie that I knew had some sex scenes. Maybe that would work, even if it was a longshot.

I was rather surprised at how well Stephie and Liv were getting along, making small talk about people they both knew. The atmosphere was very relaxed, and while she had been an excited mess earlier, my sister was a cool customer when it came to acting out the little scenario she had planned out in her mind. I even noticed that it was getting warm in here, and wondered if she had gone so far as to turn up the heat to get us to take off our clothes.

Liv was wearing jeans and a cute little white blouse, which I couldn't foresee her taking off to cool down. But I knew Stephie would work something out. I was wearing gym shorts and a t-shirt, and nothing under my shorts. If I lifted my leg just right, and my dick was flopped across my thigh, you could see it plainly through the legs of my shorts. I knew Stephie saw it a few times, and she just smiled like she was trying not to laugh. For some reason, even though my girlfriend was sitting right next to me, I just wanted to fuck the life out of Stephie right now. It wasn't so much that I was horny, I just felt this intense emotion toward her. I restrained myself though, obviously.

When the first sex scene started in the movie, Liv blushed a little. I moved her hand slowly to my crotch, and she let me place her palm right over my dick. When her fingers tightened around it, it started to get hard. Stephie didn't notice, at least it appeared that way. I knew she would pull something out of her sleeve any minute to get things rolling.

"God, I hate this movie," she said, making me frown. What was she doing?

Liv looked over at her, temporarily ignoring my shorts. "Why? I think it's kind of hot."

Stephie smiled. "That's why I hate it. It always gets me worked up and then I can't sleep. I don't have a boyfriend right now, so I don't get much relief...outside of the shower head."

I found myself laughing, and not as part of an act. But a brother probably shouldn't be laughing at his sister saying that, I thought. Still, it had the desired effect, and Liv giggled.

"That's too bad," she said, looking at me for a moment. She started to speak, but changed her mind.

"I'm so jealous of you two," she said, but kept her attention on the tv.

"Well actually," Liv said, showing a bit of boldness, "we haven't really gone that far yet."

"Really?" Stephie finally looked over at Liv. "With your hand on his dick, I figured you were getting it regularly."

Liv whipped her hand back into her lap, but it made all three of us burst out in laughter. Liv was totally embarrassed, but it might have been the perfect thing to break the tension and allow our night to progress.

"I'm sorry!" Stephie said, out of breath from laughing. "Sorry, bro. Didn't mean to ruin your fun."

"I think you get off on it," I ventured, hoping it wasn't too bold of me.

Liv's eyes widened, but she just kept laughing. "I think you're both definitely related."

Stephie's eyes twinkled as she grinned. "It's our parents' fault. They didn't raise us with much dignity, we're practically uncivilized with the way we act around each other."

Liv's demeanor changed slightly, as she pondered the overtones of what that might mean, considering what I had already told her about our habits.

"Yeah well, careful what you reveal," I said. "I haven't told her everything about our family, otherwise she'd never date me."

Again, Liv seemed to be picking up on the subtle hints of our words, and since I had revealed something very private to her, she was now wondering what I could have left out. But I knew she wouldn't imagine that I was speaking of incest.

'll keep my lips sealed then," Stephie said, and made sure Liv saw her wink at me.

Liv let out a chuckle. "It's warm in here, isn't it? Or was I just laughing too hard?"

"No you're right, it is warm." Stephie stood up and walked over to the thermostat. She pretended to study it for a moment. "I bet the air conditioner stopped working again."

"That sucks," I said.

Stephie came back and sat on her separate couch again. "Did you warn your date about our amateur method for fixing it?"

I just smiled when Liv glanced nervously at me. "Don't embarrass me, now..."

Stephie pulled her shirt off and flung it across the room, leaving her completely topless. Liv's mouth opened in surprise, but it wasn't the utter shock and repulsion that I imagined in my worst-case scenario. Still, it was a bold move on Stephie's part, and she would have had to pay with her ass if Liv had reacted badly.

"Wow, you weren't kidding!" Liv said to me, and stared in disbelief at my sister's wonderful tits. "You guys are pretty open with each other."

"It's kind of a requirement for this house," Stephie said, hooking her thumbs into her waistband and flinging her pajama pants off. She wasn't wearing panties, Liv and I discovered.

Liv gave me a brief glance, a mix of confusion and reassurance. I just shook my head, like this was normal and to be expected. I think she was starting to get it. The next move would decide everything.

"I know Brian told you that we're partial nudists," Stephie said, looking more serious than before. "You don't have to do it with us, but we almost never wear clothes at night. It's just a tradition in our house. Can you keep it a secret?"

That was it! I was amazed at my sister's genius once again. Liv probably would have just played along and let us do our thing, but not participated, had Stephie not added the layer of secrecy. Liv's initial embarrassment and shyness would have kept her from participating, but her comfort with us on a personal level would have allowed her to accept it. Now though, with my sister asking her to keep our secret, and thus adding her to our circle of trust, Liv would feel grateful that my sister was befriending her in such a way, and would feel honored that her boyfriend's family was entrusting her with a secret that would potentially ruin their reputation. To top it all off, Liv was horny. So any misgivings about the whole thing would easily be smoothed over with her physical cravings for the kind of closeness that we were offering her.

I could have kissed Stephie, but I was too engrossed in watching Liv's reaction.

She looked at both of us, glancing back and forth, and then just nodded. "Of course I will, I would never tell anyone this kind of thing."

Stephie and I beamed, and my dick was at full mast by now.

"Come on, Brian," Stephie said, sitting cross-legged on the couch naked. "Your turn."

I pretended to be reluctant, but quickly peeled my strained shorts from my body. My dick was pointing at the ceiling.

Liv covered her mouth, almost laughing in embarrassment.

"Don't worry," Stephie assured her. "I'm not bothered by that tiny thing."

I shot her a funny look, and we all just laughed. Liv was touching her stomach now, as if her clothes were starting to itch. She was about to join us, I could tell.

"You don't have to, babe," I said softly to her. "But it would be really fun if you did."

Liv was fighting her inhibitions, never having done this before. But she had said she knew some girls who were nudists, and I think she was beginning to feel like the odd person out.

"Come on, Liv!" Stephie said. "It'll be fun. I promise not to look at you two getting frisky."

Liv sighed. "I don't believe that for a second." Then she stood and unbuttoned her jeans and blouse.

I swear Stephie licked her lips when Liv's naked body was revealed. She might not have been into girls, but just the reward of getting Liv to strip for us was enticing. She quickly sat back down next to me, as if hiding her pussy. But she didn't try to cover her cute little tits from us.

"Yay!" Stephie was excited. "Another member of the club. You can come over to our house anytime."

Liv smiled. "Thanks! I just know your parents are going to come down here and chase me out any minute."

I ran my hand over her thigh. "Don't worry. You can trust us."

That was what this all boiled down to, in the end. Mom was right, if people accepted us for who we were, then that meant they trusted us and required our trust in exchange, to keep our mutual secret. It didn't mean we were doing anything wrong, but keeping it a secret made it more special. Now I would do everything in my power to keep Liv around, to build up our relationship and hopefully integrate her into our family.

We somehow went back to watching the movie, and Liv and I were cuddling very close. I was hard the whole time, and she openly played with my penis in front of Stephie. Stephie played it cool and didn't make a big deal of it, but I knew she was dying to come over and help her. I would have to give my sister a special treat later...

Before the movie ended, and I was about ready to blow, Liv stopped touching my boner and leaned close to whisper in my ear.

"Jerk off for me," she cooed.

My dick twitched, and my hand found its way instinctively to my cock. Liv wanted to see what Stephie would do, and I could see her eyes darting over to my sister. Stephie knew what was going on once I grabbed my dick, and couldn't have paid any less attention to the tv.

"You're learning fast," she said to Liv, giving her a warm smile.

Liv smiled back, and before her attention moved back to me, I saw her hand reach for one of her small breasts. She was getting off on this! I felt like things couldn't get any better, and that pushed me over the edge way too soon. I groaned and began spurting fluid all over myself. It was a huge load considering how much I had spent myself already today. Liv's eyes were glued to the sight of my ejaculations. Stephie slowly moved off her couch and crawled a few feet closer, not saying anything, just following her interest in what was happening.

"Oh my god," Liv said, seeing me cum for the first time.

I grunted as the last few spurts left my dick, leaving me exhausted but completely satisfied. I wish I could have lasted longer though, so that one or both of them could have joined me.

"Good boy," Stephie breathed, for the first time betraying how turned on she was. She wasn't holding back for Liv's sake anymore. "That feel good?"

Liv watched us both carefully, her arousal high but her curiosity winning out. Did she think we were incestuous now, based on how turned on Stephie was? I was worried for a moment, but so satiated that I didn't really care at this point. Even if she thought that, I knew she wouldn't freak out and spill the beans to anyone.

I nodded. "That felt great, I can't believe I came so soon."

Liv gently touched my chest, comforting me almost. "That was really sexy."

Stephie inched forward more and squatted right next to where Liv was on the couch. "That's the benefit of having a close family. You get to be totally open with everyone. And it feels good!"

Liv was still wary, but beginning to let down her guard. "You masturbate for him too?"

Stephie nodded, waiting for Liv to react. "We don't do anything the other person doesn't want, we're just open with each other."

Liv touched her breast again, her nipples hard and her hands shaking. She was so turned on, but still so nervous. I had to do something to ease her fears.

"We're not expecting you to just jump right in," I said, sitting there covered in my own cum. My dick was still dripping as I spoke. "We can still have fun by ourselves if you prefer, or we can just hang out and not fool around too. We're not just all about masturbating."

Liv nodded, and I could tell that she needed to hear that. She wasn't going to masturbate with us tonight, and that was perfectly fine. The next time, Stephie and I could do whatever we wanted in front of her, and when she felt comfortable, she could join in. There was no pressure, and that was going to help out in the long run, especially if my parents were involved.

Not long after, since it was so late, Liv decided to dress and leave. I walked her to the door, still naked, and made out with her for a long few minutes in front of Stephie. She was already less inhibited around us, I could tell. After she left, Stephie just looked at me intensely.

"I know your dick is spent," she said, her eyes piercing into me. "But I need your body tonight."

"I owe you big," I said, walking over to her with my dick swinging between my legs. "I'll give you everything I can."

She grabbed my hand and led me upstairs to her room.

Chapter 7

Stephie was awoken by something shaking her, or rather jolting her rather consistently. It took her a moment to realize she had fallen asleep face down on her bed, and something was moving on top of her. It was me, her brother Brian, and I was humping her. When I thrust sharply, she felt my cock buried all the way up her asshole. I wasn't cumming, but I stopped for a moment when I saw that she was awake.

"You fell asleep," I said quietly, but without reluctance or hesitation. Then I resumed butt-fucking her, but a bit slower now.

"I can't believe it," Stephie sighed, that wonderful feeling of fullness making her body vibrate with pleasure. "I guess I passed out."

I kept up a nice steady pace, driving my cock back and forth, sawing my way in and out of her body. I hadn't cum since earlier when I had jacked off in front of her and my girlfriend, Liv. That was hours ago, and since then the two of us had been fucking like rabbits. Stephie had more orgasms than we could count, and I was still rock hard. When she had passed out, I was so worked up that I couldn't stop. I had to cum, and besides it turned me on to be doing my sleeping sister, in the butt no less. I knew she wouldn't mind.

"I can't believe it feels so good," Stephie sighed contentedly, relaxing even though I was getting forceful again.

"You mean in the ass?" I asked, gritting my teeth with every thrust.

She nodded, purring as I plowed into her. "I feel like there's nothing we can't do with each other."

"Yeah, I know," I replied, feeling my balls begin to tighten finally. "It's great."

"I've never felt like this before," Stephie continued. "My body is on fire when we have sex. I think about fucking you all the time now."

"What about Dad?" I asked, knowing I was ready to cum soon but it would still take some work.

"Mmm, how would you feel about that?" she replied.

"Well I've already fucked Mom, so I can't complain. She says that you were waiting until we got together."

Stephie turned her head around to look at me, but her body remained still while I ravaged it.

"Cum in my ass, Brian," she said, looking me right in the eyes. "Fill me up with your sperm."

I groaned, her words spurring me on, and finally after the longest fuck of my life, I felt myself begin to cum. I almost roared as the white hot pleasure shot up my shaft, and I began pumping my sister's cute little butt full of my seed. I held myself deep inside of her, feeling her ass clench around me, and she groaned with me as I helplessly spewed jet after jet of gooey cum into her bowels. It was so naughty for me to be doing this, but that only made it feel better.

"That was awesome, Brian," Stephie purred. She reached back and touched my face. "Please, promise me that you'll do that whenever you feel the slightest urge."

I kissed her back, and slowly withdrew my slimy dick from her. "I promise."

That Friday, I was so nervous I couldn't even get hard to jack off like I did every morning. I just sat awake in bed as the sun was beginning to rise, though I thought about waking my sister Stephie up for some sex. Instead, I just sat and wondered what the nudist party would be like.

I was most worried about getting a big erection in front of everyone there. Mom had assured me it wasn't uncommon, but that everyone just ignored it when it happened. And maybe that was true with the adults, but what about the other teenagers like me? The Christiansen's daughter Becca was a total fox, and if she saw me with a huge boner it just simply couldn't be ignored.

And even aside from that one worry, what about the interactions of all the families that would be there? Were they like my family? Did they "express" their close feelings in the same sexual way? I couldn't just go up to Becca and ask her if she fucked her parents. Mom had said that we had to be careful around other people so as not to reveal too much about our special relationship. But did that include the families that would be at the party?

All morning, I couldn't help but worry. Stephie had gone out, and of course Dad was at work. It was just me and Mom at home. With very little resistance, she had agreed to talk with me about my concerns. In her bedroom, of course.

Before I even knew what was happening, Mom was naked and spreading her legs for me. I melted into her and within moments I had sunk into her tight pussy. I drove myself deep to the hilt, and just stayed like that. Mom smiled up at me, and started to gently stroke my face.

"Are you nervous about tonight?" she asked, as if having this conversation with her son, while his cock was buried inside of her, was a normal and maternal thing.

"Yeah," I answered, resting my face next to hers on the pillow. I tensed my cock inside of her, and I felt her pussy respond with a nice firm clench. "I'm worried about embarrassing myself."

"Oh, don't worry," she said, undulating her hips a bit. "You can let off some steam right before we go. Or..."

The way she said that, and left the word hanging, enticed me. "What? Or what?"

Mom just smiled and patted my head, kissing my cheek. "I don't want to spoil it, but you seem so worried I just can't bear it."

I propped myself up on my elbows and stared at her. I forgot my cock was buried in her tight cunt for just that moment.

She sighed. "Your father will kill me, so don't say anything. There's a tradition at these parties."

That got me excited for some reason, and I started fucking her finally. She moaned and seemed to be enjoying it a lot. I had a morning load of cum to rid myself of, and it looked like I would be filling up her pussy with it. I didn't ask any more questions, I just kept fucking. We didn't kiss or anything, and it wasn't especially intimate. It was just rutting and our bodies pushing against each other. When I finally spewed, it was fairly intense but mostly just a relief. I emptied my balls with a deep groan and Mom purred approvingly.

"What's the tradition?" I asked, rolling off of her and lying next to her.

She just laid there, with my cum leaking out of her pussy. "You're the first new guy to go to this party in a long while. I wasn't entirely truthful with you about what goes on there. I wanted it to be a surprise."

"Is there...sex?" I asked, sheepishly for some reason.

She nodded. "We eat dinner and talk and just have a good time. But it ends in everyone getting off one way or another. In fact, no one is allowed to leave unless every single person has had at least one orgasm. Women included."

"Wow." I had to think about that for a while. I imagined Stephie going to these parties, as Mom had said she had done already. Who had she fucked or sucked or whatever at these things? Or Mom for that matter?

"We didn't tell Stephie for her first time," Mom said. "She was very surprised, but she acclimated very nicely to the scene."

"Do family members have sex, like us?" I asked.

Again, she nodded. "Yes, it's all people we can trust. We're very close. I usually get a good five or six loads in or on me at these functions."

The mental image of Mom covered in other guys' semen was making me hard again. I got back on top of her, but this time I stuffed a pillow under her hips and held her legs up. I pointed my slimy cock at her little pucker and pushed it inside of her. My dick slipped right into her ass.

"Ooh," Mom said, moaning in pleasure. "Again? So soon?"

I buried myself in her butt and held it as far as I could get it, and smiled as she began to masturbate while I filled her bowels. I kept fucking her ass for a good few minutes, getting more details out of her between her climaxes while I did that.

"So, is there a game of it?" I asked, thrusting sharply into her anus. "Or is it just straight fucking?"

Mom rubbed one out just then, and waited for the orgasm to finish washing over her before answering. "You'll get teased. Becca, the Christiansen's daughter, is the worst."

"She isn't that much older than me, how many of these things has she been to?"

"A few," Mom answered, clenching hard on me with her ass. "She usually has the record for most orgasms given."

"You guys keep track?" I could feel my balls tingling again, not just from the anal sex but also from the naughty details I was getting from Mom.

"She does," she replied, and started flicking her clit again. "God, my ass must still be all worked up from her father this morning. It feels so good!"

Picturing my Dad fucking her ass only a short while ago somehow turned me on, and I came again. It felt glorious to cum inside of my mother twice in one morning. I could do this everyday.
