Hi, I’m mark 16 years old. A normal teen boy with the usual teen interests. I’m about 1,8m tall, weigh about 75kg, blue eyes, dark brown hair. I’m no superman, but keep myself in decent shape.
I have a stepsister, Lisa who is 18. She is tall, slim, with long light brown hair, and beautiful C cup breasts and a nice round butt.

Its Sunday morning, the sun shining trough my window woke me up. I laid dozing in my bed like I always did when I had a free day. Our parents was away for the weekend, so there was no one bugging me to get my lazy ass out of bed.

Around 10 o’clock my step sister came into my room. Without knocking as usual, and smiling like she always do. I love that about her, she is always smiling and she has a beautiful smile too. She was standing in the door frame, wearing a set of black panties and matching bra, apparently just got out of bed herself. She looked incredibly sexy, and my cock started to harden as my thoughts drifted to last nights event. “Good morning lazy” she said, “morning, just got up?” I answered smiling back at her. “yep, I was just heading for a quick shower before fixing breakfast”. She was just about to turn around and leave for the shower when she noticed I starred at her. She took a couple of steps into my room “like what you see?” she asked. “yeah, you look stunning” I said. She stood there looking back at me for a moment, then she came forward and sat on the edge of my bed. “Want to join me in the shower?”, “I would love to” I answered.

She took my hand, and almost dragged me out of bed. We stood looking at each other for a second, then she leaned in and kissed me, “lets go”. We walked to the bathroom, still holding hands. Once in the bathroom, Lisa turned on the shower. While we were waiting for the water to warm up she turned towards me. “What do you think about last night” she asked “was it really your first time?”. “Yes it was” I said “And it was amazing, I cant stop thinking about it. I feel so lucky to have a sister like you”. “I’m glad you think so” she answered, smiling even broader now. “I only wish i had been sober” she laughed. “maybe” I said, “but would you have done it if you were?” “Probably not” she said giggling. She took a step closer and told me to take off her bra. I reached around her, fiddling with the clasp. It was the first time I had touched a bra, and my excitement probably didn’t help either, but eventually I was able to loosen it. Her beautiful firm tits felt so nice against my chest as we held each other and kissed. I let my hand drop down and I cupped her butt, before I let my hand trace over her covered pussy. “mm you’re getting confident” she said, “good I like that”. “Go ahead, take off my panties too”. I hooked my hands inside her panties, and slowly pulled them down over her hips and let them fall to the floor. I looked at her beautiful clean shaven pussy, her sensual clit just visible. My step sister is one of the most beautiful girls i have ever seen. She stepped away and told me to take off my own underwear. I dropped my boxers, and we stood there for a second. Both naked admiring each others bodies. “Come on” she said and stepped into the shower. Our shower was quite big, and could comfortably fit two persons. I have a suspicion that’s exactly why our parents had chosen it.

“You have an amazing body” I told her as i watched the water flowing over her. Her body glistening as she got wet. “can i touch you?” “Of course you can, anyway you want” she said. “And by the way, you don’t look bad yourself”. I stood close to her, close enough i could feel the warmth radiating from her body. I put my hand on one of her breasts, cupping it, gently squeezing it. Then i put my lips to her nipple and kissed it, letting my lips and tongue explore her breasts. I straightened up and asked how it felt. She told me it felt really nice. I continued to caress, kiss, and lick her tits. Enjoying the sounds of her soft moans as I did. Her tits aren’t huge, but round and firm, and the size is proportional to her body. We continued like this for a little while, her hands stroking my hair and back as I enjoyed her tits. Then she gently lifted my head, and we kissed again.

Although this was only our second time together, we seemed to establish a kind of tradition. Ever since, kissing has been a big part of it. We both love it, and it makes everything so much more sensual.

“So you have never licked a pussy” she asked me, and I told her I never had. In fact, until last night I had never seen a pussy in real life. “Do you want to” she asked, “oh yes” i answered eagerly. I slowly got down on my knees, it was a bit awkward on account of the cramped space of the shower. As i leaned in, i sensed the smell of her wet pussy. A smell i have loved and cherished since. I cautiously let my tongue trace up her slit, and discovered it tasted as good as it smelled. As i grew more confident and eager she told me what to do. She told me to lick her clit, gently suck on it, circle it with my tongue. And also let my tongue play with her pussy lips. She moaned between her words, and this made me more eager. I stuck my tongue inside her, and lapped up her juices. After a little while she told me to use my fingers too. I began to finger her, letting two fingers push into her before sliding them out again. While my lips and tongue focused on her clit. I could feel rather than hear her breathing becoming heavier. Her moans became louder and more frequent, and she had stopped talking all together. I realized she was nearing an orgasm, and that made me a bit bolder. I started to finger fuck her a little faster, and as I sucked on her clit I let my teeth carefully scrape it. At that moment she started shaking, and let out a loud moan. Almost a scream. For a second I was afraid I had hurt her, but i soon realized she was having an orgasm. I stopped fingering her, but continued licking her until she sank down on her knees. She sat there in front of me for a moment, eyes closed, breathing heavily. Then she opened her eyes and smiled at me. “That was so good” she told me, and then she kissed me again. We sat on our knees, holding around each other and kissed passionately for a while. “I’m so happy you enjoyed it” I told her between kisses, “I liked it too”. “I want to return the favor” she said, “stand up”.

I stood up, Lisa was still on her knees. I looked down as she gently took my cock in her hand. She slowly stroke my cock a couple of times. she kissed the tip of the head lightly. Then she opened her mouth, letting my cock slide in between her lips. It was so good to feel her take my cock in her mouth. And it was so sexy to see my own step sister on her knees in front of me, sucking my cock. I closed my eyes and tilted my head back. Feeling the water flow over my face and down my body as I enjoyed my sisters blow job. It felt so amazing, and I found I had to concentrate to keep from cumming. I wanted this moment to last as long as possible. My cock slid in and out of her mouth, her tongue caressing the length of it. Occasionally she licked the tip and kissed it. I realized I couldn’t hold it much longer, and told her i would cum soon. “mm good” she said and continued sucking me. Her hand cupped my balls, and massaged them. That brought me over the edge, I had to lean on the walls for support. I felt her lips clam around my cock as i shot my load into her mouth. She continued sucking until my cock started softening, and I kept my eyes closed for a moment longer. Savoring the moment. When I opened them, she was standing before me again. She opened her mouth and I saw she still had some of my cum in her mouth. She kissed me again, and I could feel the taste of my own cum as we kissed. It was a strange salty taste. But not a bad taste.

After that we took turns cleaning each other. I used my hands to soap and clean Lisa s gorgeous body. Using the opportunity to explore every inch of her. Her neck, breasts, belly, back, ass, legs, even her feet and toes. Occasionally kissing whatever part of her I was currently focusing on. And she did the same with me. By this time we realized the water was getting colder, and we had emptied the water heater.

We turned off the water and stepped out of the shower, and grabbed a couple of towels. We dried each other off much in the same manner as we had cleaned each other. Me using the towel to dry her off, this time paying special attention to her butt. And what an amazing ass shes got. Round and firm and beautiful, just like the rest of her. And she dried me off in turn. I enjoyed her touches trough the towel. Then we got dressed. Well that might be a bit of an over statement. She put on a pair of bright red panties and a matching bra, and I put on a pair of black silk boxers (my favorite pair), and we dawned a couple of bathrobes. We realized the clock was almost 11am, and we were both getting hungry so we went down for breakfast.

We made a good Sunday breakfast together. Bacon and fried eggs, toast, orange juice, coffee, the works. It was a nice warm and sunny Sunday in early June. So we decided to eat out on the balcony. Our house is situated somewhat privately at the end of the road. So no one would notice us sitting out there half naked. We ate most of out breakfast in silence, partly enjoying the quiet Sunday, partly thinking about the turn our relationship had taken. I realized I loved having sex with my step sister, but i also discovered my feelings for her hadn’t changed much. I still felt the same towards her, only stronger. I loved her, but I loved her like a sister and not as a girlfriend. This almost surprised me a bit, because I half expected to fall in love with her. And it also scared me a bit, because i was unsure how she felt towards me after all that had happened.

We were enjoying our coffee when Lisa started speaking. “We need to talk about this” she said. “Before we get too deep into anything”. I nodded, and listened. She said she had really loved having sex with me. And I told her I loved it too, “I noticed” she said with a smile. “But” she began, “I need to make sure we don’t do anything that will harm our relationship, we have always been close” she continued. I was a bit nervous now, half expecting her to say we couldn’t do it anymore. “I love you” she said, “but I will never fall in love with you, you are my little brother and you will always be. I hope you understand what I mean”. “I know what you mean” I responded, “I love you like my sister, and I feel our bond have grown even stronger now. But i feel the same way about this as you”. “Great” she said, smiling broadly, “I hoped you would say that”. “Does this mean we can have sex again?” I asked her. “Yes” she answered, “but we need to be careful, it has to be our secret” “Of course, I know that”.

A bit later that day, I went out to visit a friend. It was a beautiful day, with an even more beautiful start. I felt better than i had in a long time as I took my bike down to my friend. We met up with some other friends, and ended up biking to a small Forrest pond to cool off in the water. When the clock neared 2pm we split up, heading home for lunch.

When I home, i found Lisa on the balcony sunbathing. She hadn’t bothered to change out of her red bra and panties. She opened her eyes and smiled as I stepped out on to the balcony. I asked her if she felt like having lunch, but she said she was too comfortable to move. So I decided lunch could wait, stripped down to my underwear and laid down to enjoy the sun for a bit. I laid there beside her, watching her. And I felt the now familiar desire build inside me. I enjoyed the sight of her incredible body. Her ample breasts, flat belly, her curvy hips, long toned legs. I felt myself growing hard from the sight, and the memory of our morning together. I couldn’t keep my hands off her, I let my hands stroke over her breasts and belly. Feeling her warm smooth skin. She opened her eyes and squinted against the sun at me. “sorry, hope you don’t mind, you looked so sexy I couldn’t help it” I said sheepishly. She smiled again “I don’t mind, it feels nice”, she closed her eyes again but her smile remained. I kept caressing her. I was horny, but I also liked the idea of making her feel good. Her eyes still closed, she reached behind her back with one arm and undid her bra. I took it off her, savored the sight of her now free tits. Neither of us said a word. She silently enjoyed my caressing, and I enjoyed the feel of her skin. I paid special attention to her tits. I took one nipple between two fingers, squeezing slightly. And she let out a soft moan, clearly enjoying it. As I continued caressing her, I reached into my boxers. Took out my cock and started jerking. She must have noticed the change of my movements, because she opened her eyes again. She watched me jerk off while my other hand played with her tits. “can I fuck you again” I asked after a while. “mm sure” she said, she lifted her hips, took off her panties, and spread her legs.

I took my boxers completely off, and sat on my knees between her legs. I leaned down towards her, holding my cock. I let the head of my cock stroke up and down her slit a couple of times, teasing her pussy. She moaned. Then I slowly started to push myself inside her. God, it felt so good. I took it slow, I wanted to last as long as possible. Not only because it felt so nice, but also I wanted to give her an orgasm. I started fucking her, long slow strokes in and out. Pausing at the bottom and just before I slipped out of her before pushing back in. I leaned further down towards her, using one hand on the floor to steady myself. The other hand playing with her tits, occasionally i would lean down to kiss her nipples or her mouth. I was able to last a lot longer this time. I kept fucking her, slowly building up speed. Soon we were both moaning loudly in pleasure. This time I didn’t notice her orgasm approaching. She arced her back and let out a loud moan. I had yet to cum, so i kept fucking her trough her orgasm. She looked me in the eyes and told me to fuck her harder and faster. “Come on little brother, fuck your big sister”. I could feel the sweat pouring out. I was going as fast as i dared without letting my cock slip completely out of her. I let out a loud moan, almost screamed. As I thrust into her one final time, our bodies coming together with a loud smack. And I released a stream of cum inside her. Panting heavily i collapsed on top of her, my head was swimming. “wow, you’re getting the hang of it” she said, “good thing I’m on the pill” she laughed. “Yeah” I responded, realizing I hadn’t given any thought that she might have gotten pregnant if she hadn’t been on the pill.

After catching my breath for a while, I went back inside. I needed to cool off for a bit, I had a drink of water before taking a quick cool shower. The rest of the day proceeded like any normal lazy Sunday. I joined Lisa on the balcony sunbathing for a little while, just enjoying the sun this time. And then I went to my room and played on my computer. Normally I would have used the opportunity of a quiet house to surf for porn online, but I didn’t feel the need for that now.

In the evening we made dinner together like we usually did when we were home alone. After dinner we sat down and watched TV together, again like we normally did. It seemed like our new found passion for incest didn’t have much affect on the rest of our life.

It was getting past 9pm when Lisa said “Our parents are coming home tomorrow, who knows when we will get the chance to be naughty again”, “You’re right” I said, “want to fuck again?” “I do” she answered. Then I asked “would you mind if we fuck in your bed this time?” “Sure, why not” she replied, got up from the couch and headed for her room.

This time was a bit less sensual. We basically just threw off our clothes and tossed them on the floor. “Do you think you’re up for something a bit more advanced” she said with a smile”. “I think so” I said, “what do you have in mind?”. “Have you heard of the 69” she asked. I said I had, I had seen it in porn films. And i thought it looked like fun. She confessed she had never done it before either, at least not with a boy. But she would really like to try. I laid down on the bed, and she got on top of me. Her wet glistening pussy right over my face. I grabbed her hips and raised my head up between her legs and started licking her. Lisa was taking my cock in her mouth again. It was really good, but a little awkward on account of us both being new to the position. But we eventually got into a sort of rhythm to it. I was licking, sucking and lapping at her pussy. While Lisa was doing the same on my cock. After a while she sat up, and lifted her pussy off my face. She turned around and lowered her pussy onto my cock. She laid down on top of me, our hips moving in rhythm as we continued to fuck. I put my arms around her and we kissed while we were fucking. It continued for a good while. By far our longest fuck yet. But eventually, after a long, blissful, happy time. The familiar heavy breathing was building. And then it happened. As our hips met, we both came. Almost simultaneously, moaning and panting together. It is a truly wonderful experience to be able to share an orgasm. At the end of a long day of sexual adventures (especially for me, two days ago I had been a virgin), we were both sexually exhausted and satisfied.

We fell asleep next to each other, I’m not sure how long I was asleep. But I woke up around 1am. Realizing our parents would be home in the morning. Lisa must have notice i stirred, because she opened her eyes, and smiled. I told her I should get back to my own bed, and she agreed that was probably a good idea. I got up and kissed her. I turned to leave, then turned back to kiss her again. Before finally getting out of her bed, collecting my clothes. And went off to my room. Back in my room, I didn’t bother to put on my underwear. I just crept naked under the covers. I lay awake for a little while, thinking of all the fun we had that day. And of the fun to come before I fell asleep
