After our first sexual encounter, my sister and I tacitly decided not to talk about what had happened. It felt really weird. On the one hand, she was my sister, and all of a sudden we had ended up having sex. That wasn’t totally okay. I guess our hormones had rushed us into having this kind of contact. On the other hand, the whole experience had felt great. I had really enjoyed touching her body, her big round boobs, her ass, and her pussy. It had felt amazing banging her.

I had been thinking about it a lot for the past days, and I kind of wanted to speak about that situation, but I just didn’t have the guts. Plus, I didn’t know what to say. I was so confused that I even thought about talking to my best friend, Freddie, but in the end, I decided not to say anything and keep the whole thing for myself.

Two weeks had passed since the incident when a friend called us. He asked if we wanted to go out and have dinner with a couple of friends from college. We thought it would be a good idea, and we agreed to meet downtown on Friday night. The day came, and Valentina, my sister, and I went to meet them.

The restaurant was nice. It was a place where they sold hamburgers mainly while they played rock music and showed videos as well. The decoration was really cool, sort of vintage Pop Art, I would say. We arrived there at 7 pm, and Matt, one of our friends, was there with Joanna, another good friend of ours. It seemed that both of them were going out though none of them talked about it. They didn’t show any kind of affection to each other either, at least not in public.

We entered the place, and some minutes later, Freddie, my best friend, and Andrea joined us. We ordered food and some wine, and we all gossiped and laughed. Dinner was complemented with a really dark coffee that was just amazing. After that, we ordered another bottle of wine and kept on talking. All in all, we had a nice chat and got to catch up with the latest events in our lives.

We said good-bye at around midnight, and Valentina and I went home. It was totally dark when we got there since we had forgotten to leave some lights on. Our parents had moved abroad a couple of years ago, leaving me and my sister in charge of the house.

We were kind of very energetic due to the coffee, I guess, so my sister proposed watching a movie. We were a little drunk, and we felt like drinking some more wine.

“Bring a bottle and I’ll set the movie,” demanded my sister.

I went to the kitchen, grabbed a bottle, and went upstairs towards our parents’ room. We had decided not to move anything from their room, so we still had a king size bed there, along with a big TV. When I entered the room, I saw my sister connecting a wire to the TV. She was wearing nothing but a short white top and some tiny green panties. I tried not to focus on her body just to avoid feeling any kind of desire.

Valentina had brought her laptop and now was getting everything ready to play the movie while I concentrated on opening the bottle of wine: a delicious Merlot.

“What are we watching?” I asked curiously.

“Nine Songs.”

“What is it about?”

“It’s about a couple who like to go to concerts, or at least that’s what my friend Gina told me. She sent me the movie yesterday,” replied my sister.

I poured the wine, gave a glass to my sister, and we said “cheers” and had a sip. Valentina got into bed while I took off my shoes, my socks, and pants. I only left my t-shirt and boxers on.

We played the movie, but immediately Valentina stopped it.

“Hey… I have felt like… you know… talking about the… I mean… do you wanna talk about the other day?” she asked me.

“What… day?”

“About the… shower… the… sex.”

“Yeah… I guess we should… talk,” I said timidly.

“Say… I don’t think it was… totally wrong… I mean, I had a good time and…”

“Me too!” I said enthusiastically.

“So, what I mean is… I don’t want us to feel bad about it. I think it was a natural thing… I mean, society doesn’t think that’s natural or okay, but we are mature enough to deal with that.”

“Sure… I… completely agree.”

I didn’t know what else I could say, so I just looked at her. She stared at me too, and somehow there was this sensation that something was going on again. Then, Valentina said, “alright,” and turned her face towards the TV. 

She played the movie again. It turned out that the whole plot was about this couple who went to concerts, yes, but also had sex all the time. And here the thing was that these sex scenes were explicit. Totally explicit. At some point, I felt my penis was starting to grow, so I tried not to get so excited. My sister for some reason was sighing a lot, and at some point, I noticed she was breathing faster than normal.

“I would say this is a porn movie disguised as an independent movie, don’t you think?” she asked me.

“Yeah… I guess.”

“Just look at that. That’s porn!”

She referred to the girl stroking the guy’s cock until she made him come. She sighed again, deeper this time while on the screen, the guy licked the girl’s pussy.

Immediately, my sister grabbed my cock and started to stroke it. I took my eyes off the screen and looked at her. I was stunned, but somehow, I just adored the view. Her hand was moving my dick, and part of her breasts were visible through the top. I moved my arm, grabbed one of her boobs, and took it out of the top. I touched her nipple and it got so hard.

Valentina kept working on my dick, and my mouth got close to her boob and started licking it. It felt so good. I really liked my sister’s big tits, so round, so soft, so arousing. I moved my right hand towards her pussy while I kept holding that boob.

I touched her cunt and rubbed it, and my sister started to moan. I introduced my index finger and discovered how wet she was. It was impressive. There was humidity all over, it even spread to her ass, which I started to feel too. I moved between her ass and her pussy, to focus on the latter again.

I introduced my middle finger this time and fingered her for a minute or so. Then, I introduced my index finger as well, and she started to moan louder. I took off her panties with my left hand, and then moved her hand away, the one that was holding my dick.

I spread her legs and put my face near her pussy. My tongue reached her lips and started to lick them. She moaned more and more. I ate her delicious pussy while I touched her boobs. Her body was so hot that my only desire was to be inside of her immediately. I tried to introduce my tongue into her hole, and I could tell that action drove her crazy.

I took off my t-shirt and my boxers, and held my dick and stroked it to make it harder. I put the tip on her pussy and rubbed it a little bit. She rolled her eyes, and I could tell she was completely horny.

“Get inside, please,” my sister said.

Getting inside was an easy task because she was so wet. I began moving slowly while I caressed her body. I also put my mouth close to her ear and started to breathe heavily and to lick it. She moaned louder.

“I like it… I really like it,” said my sister as if she were out of breath.

I kept on moving, now a little faster, and she continued telling me things, which made me feel so good. I looked at her mouth and thought I wanted her to suck my cock.

I stopped. I got on my knees and moved towards her head. I put my dick between her breasts, and she pushed them towards the center to press my shaft. That was heaven. I moved my dick up and down, and finally reached her mouth.

She licked the tip and then grabbed my penis with both hands and pulled it towards her. My dick was inside her mouth for the first time. She sucked it gently, slowly, and I was in ecstasy. It was the best blowjob I had ever received. Sis was so talented at that.

She also used her hands to give me more satisfaction. First, she rubbed my cock, up and down, and then she moved them to work on my balls. She used two fingers alternately to move my testicles, and I must admit it felt amazing. Then, she lifted one of my balls and introduced it in her mouth. She sucked it really well.

Then, I moved my head towards her feet and went back to her pussy. She put my dick into her mouth again while I licked her hole. At the same time, I grabbed her ass and started to move to the center. I used my index finger to collect some of her wetness and put it in her anus. I rubbed it for a couple of seconds and then introduced my finger. She moaned in ecstasy. I fingered her anus while I licked her pussy.

After a couple of minutes, she told me to penetrate her again. I held her waist and made her turn around. Then I lifted her ass and penetrated her pussy from behind. On the screen, the couple went to a concert, and a band that I like, The Von Bondies, started playing a fast song. That turned me into a machine that moved very quickly inside my sister’s pussy. My sister screamed and moaned, and asked me for more. I licked her back from her anus to her neck. It was the wildest sexual act I had had in my entire life. The best one, it didn’t matter it was my sister I was fucking.

I kept on penetrating her and while I did, I put my right thumb into her wet anus. She screamed several times, and that made me feel more aroused. I slammed her ass with my free hand and then grabbed her tits, which were hanging and moving at the same pace as I banged her. Then, I used the same hand to rub her clit, which just drove her crazy to the point she could not take it anymore. Her thighs contracted, she screamed louder, and then she fell on the bed as I kept my dick inside and inserted it as deep as I could, which also made me reach heaven, or hell, as I was doing my sister.

I stayed on top of her, kissing her back, touching her boobs while she moaned and breathed fast as if she had been running a marathon. She told me to lie by her side and so I did. We looked at each other’s eyes, and then we kissed and caressed our bodies.

The next day, I woke up naked next to Valentina. We made love one more time and talked again. We decided we could continue having sex and exploring our sexuality. This could be regarded as a preparation for our future life. We agreed on a couple of rules also: we would not have sex more than once a week, no anal whatsoever, and we could see other people as long as we told each other about it and took precautions. And the most important thing: our parents should never know what was going on.
