Its been a week since I lost my virginity to my step sister Lisa. Since our parents have been home, we havent had the opportunity to have sex again. But we have talked about it a lot. I have always been very close to Lisa, ever since our parents started dating. We have always spent a lot of time together, and our parents havent noticed any change in our relationship. But our conversations have changed, to the better.

On tuesday we sat and talked in my room. Our talk started out about our weekend home alone. And about how we couldnt wait to have the house for ourselves again. Lisa told me she thought it was such a turn on she got to be my first. She had never been with a virgin before, but it was something she had wanted. I asked if she could tell me about her first times. She told me her first sexual experience was with another girl. Her best friend Tina. They had started out of curiousity, and they still played together sometimes. Friends with benefits she called it. This intrigued me, I had always liked watching lesbian porn. And Tina was at least as good looking as Lisa. The thought of them together made me hard.

Over the next couple of days Lisa told me more about her experiences. She had quite a few of them. Lisa is not a slut, im sure some would say she was. But she loved sex, shes bisexual and likes both girls and boys. But she was also very picky about who she let into her panties. I was really turned on by hearing about her experiences, girls, boys, threesomes, outdoors, fitting rooms in clothes stores, public bathrooms to mention some. Needless to say, I jerked off a lot thinking about it all after going to bed.

The next Saturday our parents told us they were going to a party at some friends of theirs. That meant we were home alone for the evening. They left at about 6 in the evening, and wouldn’t be back until well past midnight. Lisa had spent the day with Tina. She told me about how they had fingered and licked each others pussies. She showed me some pictures she had on her phone. They were nudes of both of them. Not having sex, but still very sexy solo pictures. I was starring at the last photo, Lisa was lying naked on a bed, her legs spread and her fingers spreading the lips of her pussy.

“I want you” I said to her “now”. I put my arms around her and kissed her. As we kissed I felt her rubbing my cock trough my pants, “I want you too” she said. We went up to my room, since my bed were the closest. Once in my room we undressed. We had waited for a new chance for a week, and were too horny to take it slow. When we were naked, we kissed again. As we kissed I put one hand between her legs, and rubbed her pussy and clit gently. While she had her hand around my cock stroking me slowly. We stood like that for a while. Kissing and pleasuring each other with our hands. I broke the kiss and told her to sit on the edge of my bed. She sat down, and I got down on my knees in front of her. I started kissing the inside of her thighs, slowly making my way up to her pussy. “mmm that feels so nice” she said, her voice laced with pleasure and lust. My lips reached her pussy, and I licked her clit before taking it between my lips. Gently sucking on it. I enjoyed the sounds of her soft moans as I licked her. I slowly inserted two fingers into her, my lips and tongue continued to play while i fingered her. I loved the taste of her pussy, and knowing it gave her so much pleasure made it all even better. After a while her moans became louder and more frequent, and her breathing got heavier. I knew she was getting close, and I started going a bit faster. I felt her legs clamp around my head, but i continued as best i could while her orgasm started flowing trough her body. She let out a long loud moan as she came. After a bit she relaxed. I pulled my fingers out of her, gave her clit a final kiss. Before climbing on to the bed next to her. I lay down beside her and kissed her. While we kissed I caressed her round firm breasts.

Lisa rolled over, ending up laying on top of me. She kissed me again before sitting up. She sat up on her knees. Took my cock in her hand, and guided it in her while lowering herself down on me. I placed my hands on her sides while she rode me, enjoying the sight of her tits swinging in rhythm with our fucking. I moved my hands and started playing with her breasts. Cupping her tits, lightly pinching her nipples. Lisa moaned and leaned down. I took one nipple in my mouth, sucked on it, licked it. I could feel Lisa rising and lowering herself on my cock while i played with her breasts. We moaned together as we fucked, passion and lust building in our bodies. I could feel the pressure building in my balls as my step sister kept riding me. As our bodies came together one final time, I let my cum shoot into her wet heaven. I grunted and closed my eyes as the buzz of my orgasm filled my body. Lisa sat still on top of me until my cock started softening. Lisa layedown on top of me and kissed me. I put my arms around her, and we kissed like that for a while. After laying like that for a little while, Lisa got up “thank you, that was great” she said smiling. “it really was” I answered grinning back to her as she walked out of the room.

A short while later I decided i needed a shower. I walked to the bathroom, still naked as i hadn’t bothered to dress after we fucked. I turned on the shower, and when the water was warm i stepped in. While I stood there cleaning the sweat of my body, my thought turned to Lisa and our activities. I closed my eyes and pictured her body as i had seen her on top of me earlier that day. I felt a cold draft, as if someone had opened the shower door. I opened my eyes and saw Lisa stepping into the shower. I was about to say something, but she stopped me by kissing me. Then she knelt down and took my hard cock in her mouth. Her lips felt amazing around my cock, and it was so hot to watch her finger herself while she sucked my cock. I just stood there enjoying the feeling and sight of my step sister sucking my dick. I have never been able to last long when she sucks me. And after a while i came in her mouth. Lisa swallowed my load and stood up to kiss me. We kissed and masturbated each other for a long time. My cock was getting hard again. Lisa looked down at it and smiled. “I want you to fuck me again” she whispered. She didn’t have to ask me twice, I grabbed my cock and moved in close to her. I slid my cock into her and started fucking. It was a bit awkward the first few seconds since it was our first time fucking standing up. But soon i was able to build a strong steady rhythm. I held her hips as I thrust into her again and again. Kissing her lips and tits while I fucked her. “God your pussy feels so good big sis” I told her between thrusts. She smiled back, “mmm and you have a good cock little bro” she answered. We were standing there in the shower moaning and fucking together. It was one of our best fucks since we started having sex together. And since I had already came twice that day I was able to last a good while. But eventually I felt the familiar sensation or an approaching orgasm. I started fucking her faster, making loud smacks as our bodies came together. And then I pulled her in hard and released my cum. Moaning loudly and panting as the cum shot out of my cock and into her pussy. By the time we came out of the shower, it was already past midnight. And though we wanted to spend more time kissing and fondling each other, we decided it would be best to go to our separate rooms before our parents came home.

It would be some time until we had the chance to fuck again. It was the beginning of summer, and close to end of the school year. As a result we were busy with exams and stuff. And our parents were home most days. We were able to sneak away for a quick session of mutual masturbation. But no actual fucking. After a couple of weeks like this, we started to become desperate for each other. I spent almost every waking hour thinking of my sisters beautiful pussy.

It was a Tuesday afternoon, and a beautiful warm and sunny day in mid June. We had a barbeque dinner out on the porch. Lisa and I were relaxing in the sun while our parents cleaned up after dinner. Our house was sitting on the edge of a forrest. Lisa suggested we should go for a walk in the woods, there were plenty of hiking trails trough the forrest. Our parents thought that sounded like a good idea. They told us not to be home too late, since it was a school night. Obviously they didn’t realize the purpose of our walk.

We put on our shoes and started walking towards the woods. I was wearing blue Bermuda-shorts, and a black t-shirt. Lisa was wearing a white skirt that reached half way down her thighs, and a tight pink sleeveless top. As soon as our house disappeared behind the trees, she lifted her skirt to reveal she didn’t wear any panties. We walked beside each other in silence, and i put my arm around her waist as we walked. We shared an occasional kiss on the way, and my arm wandered down to her ass a few times. I had a massive hard on that was clearly visible trough my shorts. As we got further into the woods, I let my hand slip up Lisa’s skirt. Caressing her butt, and between her legs. She was wet, very wet. And while we walked she caressed my dick trough my shorts. We had both grown up around this area and new every inch of the woods. After a while we left the trail, and walked in trough the trees. And eventually we reached a secluded clearing beside a small pond. Lisa turned towards me and removed her top. She wasn’t wearing a bra either. I pulled her close to me and kissed her. We kissed passionately while I fondled her breasts. While we were kissing, Lisa pulled down my shorts, released my cock and started jerking me. We stood there for a long time, kissing and fondling each other. My hands moved to other parts of her body too, her firm butt, and her shaved pussy. But her tits got plenty of attention as well. My step sister has one of the most amazing bodies I have ever seen.

I told Lisa I needed to fuck her now, and I wanted to take her from behind, doggy style. She smiled, her eyes full of lust. She evidently like the idea as much as I did. She got down on her hands and knees. Pulled the skirt up around her waist, and I dropped down on my knees behind her. I eased my cock inside her tight pussy. She was so wet it was almost dripping, evidently as horny as I was. Once I got my cock in her, I grabbed her ass and started fucking her. Lisa pushed her body back to meet my strokes as we fucked. We fucked hard and fast, like only a couple of sex depraved lustful teenagers can. We had waited so long to get another chance to fuck. We moaned and grunted in unison as I pushed my cock into her again and again and again. Filling the woods with the sound of our lust. Since it had been a while since last time, i wasn’t able to last very long. And soon I shot my load in her pussy. I kept fucking her until my cock softened. I sat on my knees behind her panting for a moment. I realized Lisa hadn’t cum yet. So I lay down on my back and positioned my head between her legs, and raised my head. I started eating her pussy while my own cum dripped out of her. That didn’t bother me at all, it kind of added an extra kink to it all to eat my own cum from her pussy. I used my fingers to pleasure her in addition to my tongue. And before long she was moaning lustily again. Lisa stood up for a bit and turned around. Laying back on top of me in a 69 position. I continued to lick and finger her as she played with my cock, which was now starting to get hard again. Lisa’s moans came louder and faster now. And I intensified my efforts. I loved making her cum, and soon she did. She had her hand around my cock when she let out a long scream like moan. Her grip on my cock tightened so much it almost hurt. I kept eating and fingering her while her body trembled with the orgasm. The intensity of her orgasm turned me on so much. She collapsed on top of me, but I continued. She lay still on me, her moans almost a whimper now. I was so horny now, my world was reduced to only our bodies and sounds of our lust. It didn’t take long before she was hit by a second orgasm. Not as powerful as the first one though. I was so horny I couldn’t stand it. I rolled her over so I was on top. Moved around so I was in missionary. She looked up at me and saw the lust in my eyes. Her chest still heaving. She looked my in the eyes and said “fuck me little brother”. And I did. I fucked her like a bull in heat. As hard and fast as I could. After cumming in her a second time I collapsed beside her. We were both exhausted, and just lay there panting and heaving for a while. “That was fantastic” I told her. “Yes it was” she replied, “my best orgasm ever, I never felt so satisfied”. We realized we should be getting back home soon. We gathered our clothes and started walking. We walked back hand in hand, and frequently stopped to kiss. We didn’t say a word, just walked back in blissful happiness. It was almost 10pm when we got back. And we almost imidiently went to bed, as we were both almost completely exhausted.

The rest of the week went pretty much like normal. It was hard getting away from our parents without them getting suspicious about what we were up to. But it was the last week of school, and the week after we started our summer vacation. But our parents still had to go to work during the days.

I woke up early on Monday. I had started to sleep naked, having sex with my step sister had made me discover how nice it felt to be naked. It was around 7am when I heard our parents leave for work. I knew we would be home alone until around 4 or 5pm, but I didn’t want to waste any time. Jumped out of bed and walked out into the hall, planning to wake Lisa. But she had apparently had the same idea, because I met her in the hall. She was naked too. We started laughing as we embraced and kissed each other. I let my hands play over her body. I started kissing her body, starting with her neck. Then moving down her chest to her breasts. I spent some time kissing and licking her breasts, while my hands fondled them. Next I kissed down her belly, leaving a trail of wet spots of my spit. Lisa leaned against the wall as I kissed the inside of her thighs. First one, then the other. Slowly working my way back up. I eventually reached her pussy, now glistening with her sweet juices. I started licking and fingering her. She began moaning as I circled her clit with my tongue. I licked and sucked on her clit while Lisa moaned. “mmm so good” Lisa said between moans. I noticed her breath quickened, meaning she was nearing her orgasm. Our adventures had made me bolder and more confident. And I decided to try something I had seen in a porn movie. I continued to lick her, and let one hand caress her butt. Slowly I put a finger between her butt cheeks, and began stroking and pushing on her butt hole. Lisa stopped moaning and stiffened for a second. But then she relaxed and started moaning again. I took that as a sign to continue. Her moans were getting loud and fast now. Encouraged by this, I pushed one finger inside her butt. Pushing my finger up her ass brought her over the edge. And she let out a loud orgasmic moan.

I stood up and kissed her. “Time to fuck” I said to her. She smiled and nodded. I took her hand and led her back to my room. We lay down on my bed. We held around each other kissing for a while. Then I mounted her. I pushed my cock inside her, and started fucking her with long slow strokes. I took it slow, making it last as long as possible. Every now and then I leaned down to kiss her. I loved watching her smile and hearing her moan as I had sex with her. I moaned as I kept fucking her, savoring her tight pussy around my hard cock. I could feel the pressure building, and slightly increased my speed. Going a little faster, but not too fast. Letting my orgasm build up slowly. I could sense Lisa getting closer as well. I used my thumb to gently massage her clit while I fucked. And after a short while we were both able to cum together simultaneously. As we both orgasmd, and my seed filled her pussy. I lay down on her, and we kissed passionately while we came down from our orgasmic high.

We lay naked beside each other savoring the pleasure of our receding orgasms. We lay in silence for a while. “I think this will be a fun summer” I said to her. “definitely” Lisa said, “I’m so glad we started fucking”. I asked her if she had any plans for the day, and she told me she would visit her friend Tina a little later. “Are you going to have sex with her too” I asked. “Maybe” she replied, and the tone in her voice made it clear the idea didn’t displease her. I asked her to tell me if she did. When she asked why, I told her it turned me on to hear about her sexual encounters. Especially with other girls, she already knew this but asked anyway. To be honest, I think she enjoys telling me about it as much as I enjoy hearing it. We lay there a bit longer, talking about our plans for the summer. Sexual and other plans. Neither of us had anything special planned, except from hanging out with friends, enjoying the warm summer, and generally being lazy. And lots of sex of course. Lisa eventually got up, kissed me, and told me she would take a shower. After watching her gorgeous body walk out, I dazed in bed for a few more minutes. I put on a pair of boxers and a T-shirt, and went down to fix some breakfast. I made some fried eggs and bacon, and had breakfast ready when Lisa came down. We ate together, before Lisa went out to meet Tina. She was wearing a light summer dress, and as she was about to walk out the door she lifted it to show me she wasn’t wearing anything under. After she left I took a shower, jerking off to the mental image of the two girls together.

I went out too, seeing if any of my friends were up to anything. It was the first day of our summer vacation, so everybody didn’t feel like doing much. We spent a couple of hours walking around town, checking out the girls in there light summer outfits. We joked about the girls we saw, who would fuck who and how. All the stupid things teen boys say about girls. One of my friend even said how he would like to fuck my sister. It was good fun, but I couldn’t help feeling a bit silly. Especially about the comment about Lisa, if only they knew. We settled down at the park, got some ice cream and relaxed.

When I got home I found my step sister sunbathing on the balcony. She had changed into a bikini. It was small enough not to leave much to the imagination, but not so small it seemed slutty. Lisa had fallen asleep in the sun, and for a while i just stood there looking at her. She looked so incredibly sexy. I knelt down beside her, and reached out and caressed her breasts. My hand slid over her belly, feeling her warm soft skin. Lisa opened her eyes, smiled and then closed her eyes again. I caressed her pussy trough the fabric of her bikini panties. She moaned slightly, barely audible. Slowly and carefully I slid off her panties. I leaned down and kissed her wet pussy. “Don’t” she whispered, still smiling. “I had enough tongue and fingers for today, I want your cock in me again” She said spreading her legs.I positioned myself between her legs, and pushed my cock inside her. “Did you have a good time with Tina” I asked her while I fucked her. “Oh yes” she moaned back, “We had so much fun licking and fingering, and fondling each other. Tina has an amazing pussy and a beautiful body” she said. Hearing her talking about Tina like that brought me over the top. And I came inside her.

After that last session we realized it was getting close to the time when our parents would come home from work. I took a quick shower and then relaxed in front of my computer. Lisa jumped in the shower after me, and was still showering when our parents came home. During dinner we talked about how our day had been. Obviously keeping some of the details out of the conversation. Lisa had put on a light summer dress, and drove me crazy by discretely showing me she didn’t wear any panties. Most of the evening was spent in front of the TV, and nothing more exciting happened that day,

I woke up Tuesday morning to the sounds of our parents getting ready for work and then leaving. When I looked out my bedroom window, I saw it was cloudy. I seemed like it would start raining at any moment. It was still early morning, around 6.30 or so. So I just turned around and went back to sleep. A couple of hours later, I woke up to the feeling of Lisa’s hands on my dick. Like all teenage boys I often woke up with a hard on. “Good morning little brother” she said when I opened my eyes. I just smiled back and enjoyed the feeling and the sight of her slowly stroking my cock while she rubbed herself. She lay down beside me, and we kissed. I put my hand between her legs and started rubbing and fingering her pussy while she jerked me off. We lay there a long time kissing and masturbating each other. Then she climbed on top of me, her pussy was hovering temptingly over my face as she took me in her mouth. I started eating her pussy, savoring the smell and taste of her juices. As I did, I remembered her reaction when I had eaten her the previous morning. I let my finger tease her ass a bit before I slowly pushed it into her ass. She didn’t orgasm right away like the last time. But it was obvious from the way she moaned that she enjoyed it. We kept going like that, and after some time I inserted a second finger in her ass. It was a bit difficult to focus on both licking her and fingering her ass at the same time. But I did my best, and after a short while her body started shaking as the orgasm hit her. When she came down from her orgasm she continued the blow job. It didn’t take long before I rewarded her efforts, shooting my cum into her mouth and she swallowed it down.

Lisa turned around, lay down on top of me and kissed me. We lay in my bed for long time, kissing and talking. And caressing each others bodies. I asked her if it felt good when I fingered her ass. And she told me it felt wonderful. She told me I was not the first to finger her ass, but she had never been fucked in her ass before. We kissed and caressed some more in silence. I could feel my cock waking up again. Lisa noticed that. She stopped kissing and looked at me, clearly making up her mind about something. She kissed me on the lips, then the tip of my cock. Then she got up and told me to stay before she walked out of the room. A minute or so later she was back. She was holding something in her hand, it was a bottle of lube. “I want you to be the first to fuck my ass” she said, “would you like that” . “I would love to” I replied. She put a generous amount of lube on my cock and stroked me slowly a bit to get it evenly all over. Then she gave me the bottle and sat on her hands and knees. I poured some lube on her ass, and spread it around her ass. As I did that I teased her hole with my fingers. Lisa moaned in pleasure and anticipation. I got in position behind her. “Are you sure you want to do this” I asked her. “Yes I am” she replied. “But please go slow and gentle”. I was so horny my body almost trembled as I placed my cock against her butt hole. My cock slid up and down her ass a bit before I started to push it in her. At first it almost seemed her ass wouldn’t open to let me in, but after a moment I was able to enter her. She groaned as I slowly pushed myself inside her. “Does it hurt” I asked her. “A little, but don’t stop” she answered, her voice was a bit strained. I continued to push inside her. Her ass felt so tight and good around my cock. And soon my whole cock was in her ass. I held still for a moment, and I could feel her ass relax a little. I started to gently fuck her, short slow strokes at first. “How does it feel” I asked her. “It still hurt a little, but it feels so good too” she said between moans. I kept the same pace for a while. She got used to the feeling of my cock in her ass, and told me to go a little faster and harder. “God sis, it feels so good to fuck your ass” I said while I slowly built up speed. I fucked her faster and used longer strokes, my cock almost popping out of her before pushing it back in. Lisa didn’t last long this time, and soon she let out a scream as she came. Her ass clenched around my cock and the combination of that and her orgasmic scream made me shoot my load into her ass.

After we finished fucking we lay down and relaxed next to each other. I asked Lisa how she liked being fucked in the ass. She told me it hurt a little, especially in the beginning. But it felt really good too. She wanted to do it again some time, but it would have to wait a little while. We spent the rest of that day relaxing around the house, hoping for better weather. We didn’t have any more sex that day, I think Lisa was a bit sore.
