GF and her Sister [MFF] [Teen] [Threesome] [Incest]

A girlfriend and her sister unbenounced to all fight for attention in a guy’s head. What will pan out after a wild day.

I walked into my girlfriend Anastasia and I’s house with one thing on my mind. Sex. I was going to lose my virginity today to her, and her to I, when she got home from work at 4:30, in a half hour. We might not have picked the best night to do it, seeing her younger sister would be home later that day (their parents didn’t usually want them around since Anastasia had turned 18, and sadly the feeling was shared) so we had to do it in daylight. I had been with her only 3 month, and I have learned she is an independent woman. I felt more strongly than anything that I loved her. I walked to my room upstairs and changed into more comfortable clothes, making sure to not wear underwear. I still had my mind on my girlfriend, and how we both got tested for STDs and came up negative. She even said she would go on the pill, so that meant we could fuck raw. My mind changed to the Olympics to kill some time. I wanted to see the soccer match going on right now. I laid down on the couch and started watching. It just hit the 10th minute when I turned it on, and within 2 minutes Anastasia’s sister appeared. She was 15, but didn’t look much like her 3 year older sister. She had blond hair and fairer, softer skin as opposed to Anastasia’s brown hair and tanned skin. She had blue eyes, yet Anastasia had brown. “Hey Danielle. Didn’t think you’d be here so early.” I said, realizing I might not get the sex I was hoping for tonight. “The longer away from my parents the better.” Danielle had a simple bath robe on, she usually wore casual clothing even when I was around. Thanks to this, I found out she has small tits, probably around a-b cup, and has a cute firm (from what I could see) ass. I didn’t know her exact height, but her head came up to about my nipples, and I am around 6’. She was slimmly built, and was pretty fit. Anastasia, had c cup firm boobs, and a rounder, slightly more firm ass. She was around 5’9, and a skinny build like her sister, but a bit more muscular. They do share one thing, they are both intelligent, and smart for their age in good ways and bad. To be honest, though I find Anastasia to be immeasurably beautiful, I always thought Danielle was cute. Really cute. I understood I was almost 5 years older than her, but still. We seemed to get together well, maybe as much as Anastasia and I. We occasionally flirted, sometimes even when Anastasia was in earshot, but it never got too serious; it was always just messing around. Anastasia didn’t seem shy about talking about love and sex with her sis, so Danielle was pretty comfortable when it came to talking about it too (another reason Danielle was smart for her age). “Can I have the remote, I have a show I wanna watch.” She asked “As a matter of fact, you can’t.” I replied. “Why not, you can just tune back in at the second half.” Both sisters were sports savvy, but only Anastasia cared to watch them. “If you want it so bad, take it from me.” I taunted, waving the remote around. She lunged for it, but I pulled it away. And like that, the hunt was on. We started wrestling on the couch for the remote, and I have to admit, it was kinda hot. Quickly she got it from me, and started to walk away, but I wasn’t done with the fight. I went to get off the couch to pursue her, but my pants fell below my knees. Forgetting I had no underwear on, I lunged for her and grabbed her robe and pulled, but it just pulled with me. Another grasp and I had the remote. I scrambled back onto the couch, and suddenly found myself dick out in front of a 15 who only was supporting an open bathrobe. I accidentally pulled the knot in the front off when trying to get the remote. We sat there for a second, my penis almost touching her perfect vagina, without knowing what to do. Finally I said “Anastasia will be home soon, so if we are doing this, we are doing it now.” Without saying anything, we both got out of the remaining clothes we had, and she knelt down and started putting my dick in her mouth. My dick is larger than average, but not by much. She seemed to have no trouble getting her mouth around it and giving me a pleasurable experience; her lips felt amazing on my cock. I was stone hard in seconds; sure this could be wrong, but it sure felt good. I went to go lick her pussy, to find she was already pretty wet. The second my tongue touched her clit she was letting out high pitched moans. After a bit of that, I thought I would explode if I didn’t get inside her. I stood up, as did she, and I realised I was staring at my girlfriend’s 15 year old sister and was about to have sex with her. “I don’t have any STDs, I already checked.” I said. “I don’t have any either.” She replied. I stared at her tits. I was right about the size, but somehow they were better that I imagined, rivaled only by her sister’s assets. “Could you turn around for a second?” I asked. She obeyed, and I got a glimpse at her beautiful butt. Firm and plump, the perfect size to be as cute as possible. “Thanks.” She turned to face me, and I saw the grand prize. Her pussy was perfectly shaved, and looked like heaven on earth. “Fuck me.” Was all she had to say for me to get going. It wasn’t said seductively, or timidly, and it certainly wasn’t commanding. It was just a request, one that I was happy to answer. I layed down on the couch, and she started getting on top of me. I saw my cock slowly slide into her pussy, and I thought I would cum then and there. She slowly raised her pussy up until just the tip of my penis was inside her. I almost thrust my penis back in right there, but I knew to wait. It took her three more down-ups to get the hang of it. Each time, I felt her tight pussy grip my penis, and yet my penis could slide in and out effortlessly. She started picking up the pace, so I started playing with her tits with one hand, grabbing her ass with the other. It felt as firm as it looked. She was starting to moan, and I finally took my eyes off her pussy. I looked her in the eyes, and she returned the glare. Instantly she started leaning into me, and I started joining in in the lower half. My hands flew around her body, mostly from her boobs to her pussy to her ass. I just couldn’t get enough of her. All the while I was fixated on her eyes. Then we kissed. Her lips were soft, yet commanding, and mine met hers eagerly. It didn’t matter that our lips were touching, or that our tongues were dancing with each other, or that we were having sex. Us being entwined was all that matters. Suddenly, my body felt all the physical joy, and we started truly making out. I brushed her blonde hair to her back as I held her neck. She held mine, and I could feel her perfect boobs on my chest. We had one long kiss, then went back to the furios kissing. We couldn’t get enough of each other. Each thrust was the best yet, each piece of skin we touched was better than the last, each kiss more passionate and more loving. My heartbeat matched with hers, and I remembered again the feeling of her my dick inside her. We had slowly, without realising it, started to pound each other. Being that we were both athletic (she mostly did running, I did a bit of everything) we could thrust with incredible speeds, always timing it so we slow down when we are about to hit each other. “I think my orgasm is coming!” She moaned between kisses. “Mine too. Where do you want me to cum?” I got out through heavy breathing. “I take pills, so anywhere.” She replied. We both knew that meant inside her, preferably as deep as possible. I took hold of her rapidly moving ass and helped with the thrusting. Then, both nearing orgasm, we kissed and held our kiss. At the same time, her legs gave way and put my dick as far in as it could go, and I came, shooting my sperm into her 15 year old pussy. It felt like all the sexual energy we had was gone, but I felt more attached to her than ever. We sat there for a minute, our naked bodies touching each other as much as possible, but not moving, my cock still in her. We kissed for who knows how long, and I had never felt more in love. Nothing else mattered. Finally, she got off of me, and I got up off the couch. She was someone different than I had seen before. Not because she was tired, not because her hair was frazzled, not even because she was nude. Suddenly, she was my lover, and that’s the only thing I saw. “Don’t let Anastasia know this happened. Or anyone else. ” I said after catching my breath. “I’ll get dressed then leave out the backdoor, then you two can have undisturbed sex.” She said matter-of-factly “How did you know.” I asked somewhat shocked. “I guessed, but I don’t mind, not even now.” I was absentmindedly putting on my clothes when I heard the back door shut. Do I love her more than Anastasia? How could I tell her? Am I cheating on Anastasia, or about to cheat on Danielle? How could I tell either? Would that drive them apart? I didn’t even know if I still loved Anastasia. My thoughts were interrupted by the front door opening. There came in Anastasia, with subtle but perfect makeup on, and a normal, everyday outfit on. We talked for some time, but I didn’t pay attention to most of it. At around 5:30, we started getting naked. It wasn’t like Danielle, this was slow, methodical, and sensual. I slowly unbuttoned her shirt, then she took off mine. We unbuttoned each others pants and pulled them down, revealing my newly hard cock. This was enjoyable, but my mind still went to the questions that barrated it. She went, moving her hands to brush past my cock, the slowly got a grasp on it. She faked putting her mouth onto it, then did, and it felt as amazing as when Danielle had it in her mouth. This time, her lips were not as soft, but were stronger. She slowly got me to rock hard, and I started to get down on her. Following the trend, I started by kissing her, all over. Then I removed her bra, and kissed her breasts. Next, I took off her panties, and licked her thighs, slowly making my way to her vagina. I liked it meticulously, getting every spot at least twice, taking my sweet time. She would moan and say yes every lick. I got up when she was incredibly wet, and I looked at her. First her tits (I had seen them once before [with her permission] but I hadn’t seen anything else) which seemed perfect like her sister’s, yet different. I asked “Do you mind turning around?” She did, and I got to see her naked ass. Dissimilar to her sisters, but just as perfect. “Thank you.” She turned to face me, and I stared at the second trophy that I had today. Her pussy was again perfectly shaven, and a mirror image of her sister’s. We went up to her room, she sat on the bed. Instantly, I knew I wanted missionary, and she did too. I rubbed my cock head against her pussy lips, not putting it in yet. Finally, I spread her eager pussy, and put my penis in. All doubts of loving her were erased from my mind immediately. For a second time, I felt like I would burst with cum that second. Despite that, I took my time getting into a rhythm, slowly getting faster, keeping my eyes on her pussy at all times. I groped her butt and breasts, massaging them, squeezing them. She started moaning approvingly, as my cock rubbed against her strong, lubricated walls. They weren’t as close together as Danielle’s, but they were stronger. They still felt great but not as great as… I looked into her eyes, and I couldn’t resist kissing her. I couldn’t restrain and go slow with this. I leaned in so I was laying on her. We kissed, one big, loving, passionate kiss. Nothing in the universe existed except for her lips and mine and our tongue dancing in each others mouths. I started kissing her more and forgot about Danielle entirely. I moved my hands around her body slowly, and hers moved around mine. We kissed slowly, but never allowing any break in between, not even to breath. All of these feelings of love were accompanied by the feelings of making love. It was painfully slow, but that was all I wanted to do. It didn’t take away from the experience, it made it perfect. “I want your cum inside me.” Was all she had to say, and I fulfilled it. We kissed each other and held it. At that moment, her legs shook and I pushed impossible deep into her and came. Then we just layed there, me on top of her, kissing, loving. At some point I got off her and we both got dressed (me with underwear this time). I felt romantically attracted to her more than ever. But the real question is was it more than Danielle.

It was around midnight, but none of us had to wake up before noon tomorrow, so it didn’t matter. We were and had been for a long time talking in Danielle’s room. Having them both with me made me realize that I love them both. At least, I think so. Neither is better than the other, neither is worse, but they are somehow different in their perfection. Spending time around both of them solidified that what I was feeling was love, not sex drive. The problem was, I couldn’t decide which was better because of their perfection. I couldn’t choose between them. I was thinking about this when someone decided to share their own thoughts. “I have been thinking about this for a while,” Anastasia started. “I think I am bisexual.” That snapped me to attention. “I am romantically and sexually attracted to both girls and guys. I am almost sure about it.” “I actually feel the same way.” Danielle said quietly. “I don’t know for sure though. What would mom and da…” “They couldn’t care less, what does it matter to them.” Anastasia cut her off. “Right.” Said Danielle, not with pain, but with something like it. They both turned to me. “Hey, no offense, but I’m not bi. I am straight, and I know it.” I said slightly defensively. “We didn’t want your confession, we wanted an opinion.” Anastasia said “I support it, it’s just…” “What” Danielle piped up. It all clicked. Then I did something I never imagined before this moment. “Let’s all fuck.” “What!” They said in unison. “You two love each other don’t you?” “Well, of…” “Not like that, you are so close because you had to be. You always do things together, and always enjoy being in each other’s company.” They looked at each other, then nodded. I was glad I was right, if I wasn’t I would have been in big trouble. “Ok, but why have sex?” Anastasia said. “I love you,” she said looking at me “ and you.” She turned to Danielle. “But.” She didn’t finish. “I love him, and he loves me” Danielle said. “We all love each other.”

“They why sex?” Anastasia asked. “Why not.” I said. In seconds we were all stark naked, looking at each other. We all got on the bed, then things were a mess. They both started blowing me while I fingered them both, and they rubbed each others clits. I was dying to get inside one of them, so they laid on the bed, Danielle on top of Anastasia, and I fucked Danielle doggystyle. She started moaning, and they started rubbing their vaginas together at the same time. They were both kissing each other, and moaning in between kisses. My hands felt Danielle’s ass while I pounded her. She seemed tighter than before, and I was loving every second of it. Her ass rippled with every stroke, not much, but a little. They switched, and I started doggystyling Anastasia. She was moaning louder than ever, and every stoke thwapped against her ass. I manhandled her ass, all the while them still kissing and fucking and groping each other. “I’m gonna cum.” They yelled again in unison, and I started rubbing my dick between their two clits, and they fell onto each other in a heap of orgasmic happiness. My cock, having been through a long day, wasn’t ready to cum yet. I layed down on the bed, and immediately Anastasia jumped on my cock, her ass facing me. Her perfect ass looked impossibly beautiful dropping on my cock, and her insides were as pleasing as ever. Danielle jumped on my torso, rubbing herself against me, and kissing me furiously. She was fingering herself, and getting quiet the pleasure out of it. I started rubbing her pussy, and the other hand found its way to slapping her ass. She moaned so loudly and so happily, I thought she was going to orgasm again right there. I kept slapping her ass (occasionally gripping it) until eventually we switched. Danielle’s tight pussy found its way on my cock, again ass facing me. It seemed so unbelievable to see another perfect ass, this time younger, bouncing up and down on my cock. Anastasia took Danielle’s former place and kissed me furiously. She rubbed her body on mine, wrapped her legs above my waist, and started grinding on me. One hand I put between their asses, which fingered their asses whenever they moved into it. The other one I used to spank Anastasia. She screamed yes when I did it, so I kept going. Eventually, they both orgasmed again in unison, and ended up sitting on the bed. I was about to cum, so I said to both of them “How do you think your sister will look with cum on her face.” And they got the hint. They both kneeled down infront of me and jacked me off at a rapid pace. I came, and got cum on each of their face. I layed down on the bed, and they both laid down on top of me. We were done all the sex and groping, but we kissed each other. I looked at the clock to see it was 1:39, so we kissed and kissed and loved each other until we slept.

The next morning we figured out a couple things. Danielle would permanently live with us (the only reason against it was because they didn’t have an excuse to take her from her parents, but it turned out their parents hate the LGBTQ+ community so that was a good enough reason). None of us would marry another, just live together and be as spouses without any weddings. We also agreed they would need more birth control pills, because we would be having a lot of sex. Also, our relationship could never be shared for fear of judgement. But we lived happily and loved each other, and most importantly, never lost our love for sex.

The End
