After our pool party, we were so hungry that my friends, Valentina—my sister—, and I decided to go out for lunch. We all took a shower and met at 1 pm. We drove to a restaurant that was on the beachside and had some tasty meals there. The seafood there was amazing, and we were all very happy about having chosen that place.

Later, we drove to another beach that was kind of isolated and spent the afternoon swimming. In the evening, we went to another restaurant, had dinner, and then went to a rock bar to listen to some music and drink some beers. We went home late, and as were exhausted, we went straight to bed. Valentina and I slept in a king-size bed in one of the rooms of the country house that belonged to Matt, one of our friends.

The next morning, I woke up next to my sister, who was naked, as this summer had had very elevated temperatures. I lay behind her, so I pressed her big tits and kissed her neck. She was half-awake now. She grabbed my cock and held it tightly. I began to dig into her pussy until I could penetrate it with one of my fingers.

She had been the center of attention on this trip so far, and I could tell how much Matt and Daniel (Matt’s cousin) desired her. Both had fucked her on a couple of occasions now, which didn’t make me jealous as I could enjoy her all the time.

After some seconds, her pussy was wetter, so I penetrated her. She was still half-asleep, but I knew she would enjoy this early sex. We spent the next six minutes in that position, and when she grabbed my testicles and rubbed them, I was in ecstasy and came inside her vagina.

What a great way to start the day. Some minutes later, we went to the kitchen and met our friends. Some of them were there. Matt, his girlfriend —Joanna—, and Daniel were fixing some sandwiches and pouring juice in some glasses. Alejandra, another friend of ours, came later. We had breakfast together, laughed a little bit, and then Matt asked if we wanted to go on a hiking trip to some nearby mountains. We all agreed it would be a good plan, so we quickly packed our backpacks with some provisions, put on the adequate clothes, and set off.

It was a one-hour drive to the site where we would start climbing. The day was sunny and very hot, and the landscape was beautiful. We arrived at the place, parked the car, grabbed our stuff, and began our walk. It was a mild climb, so it was not going to be so demanding. We went uphill for almost two hours until we reached a peak with an amazing view. There we could see a nice valley on one side and the ocean on the other.

We unpacked some sandwiches, ate, talked, and then went to a kind of cave Matt had discovered with some friends some years before. The good thing is that the place was not a tourist spot, so nobody was around. We reached the cave after a while, took some photos, and had some snacks.

It was 5 pm when we decided to go back. On our way home, we stopped in a restaurant and had dinner. We also went to a supermarket and bought more beer. Back at home, we had some drinks, listened to some music, and when it was time to go to bed, Matt said we should swap sleeping partners.

I knew he wanted to sleep with my sister, and my prediction was confirmed when we said we agreed with his proposal because immediately he grabbed my sister’s hand. Alejandra, who had slept with Daniel these days, came with me to my bedroom, and Joanna went to sleep with Daniel.

As soon as we closed the door of my bedroom, Alejandra got naked, and we began to have sex. I really loved Alejandra’s body. She was a slender brunette with curly hair and sexy small breasts, who was addicted to sex. We fucked for almost thirty minutes, and it was a good time to enjoy each other’s bodies.

When we were done, we lay in bed and spent some minutes cuddling and talking. However, in the room next door, I could hear the screams of my sister Valentina who was being fucked by Matt.

The next day, we woke up late, had breakfast in the kitchen, and later Matt, the leader of the group in this trip, presented the plan for the day.

“Guys, we are going back home tomorrow, so I think we should put an end to this adventure with an unforgettable show. I want us to have an orgy tonight. I was thinking of inviting some friends over so that we can fuck other people.”

We were surprised, but we all thought it could be something fun to bring a conclusion to this cool trip. We discussed the pros and cons, and after several minutes, we were all in.

Later, Matt and I went to the supermarket to buy some things for the evening. Once we were there, we grabbed some beers, snacks, and he also went to the pharmacy to buy other things. When he left the pharmacy counter, I saw he had some packages and some boxes.

“What’s all that?” I asked.

“Condoms and Viagra,” he explained.

“What?”

“Well, as more people are coming, we need to take precautions, so we need the condoms. And as it’s going to be a long night, I think it would be good to have some extra boost, don’t you think.”

“How did you get the Viagra?”

“A friend of mine is a doctor, and he did me a favor and gave me a prescription.”

We went back home, had lunch with Daniel and the girls, and spent the afternoon in the pool. Later, around 6 pm, we started to get ready for the wild night.

At about 7 pm, some friends of Matt’s started to arrive. There were some hot girls there, which increased my excitement.

I didn’t see my sister for a while, but some minutes later, she joined us. She looked stunning. She was wearing a semi-transparent strappy black dress that gracefully revealed part of her big boobs and made her look hotter than ever. Her hair was wet, which made her look wild, too.

By 9 pm, all the guests had already arrived. We were all in the living room, talking and having some drinks. At that moment, Matt took the floor.

“OK, ladies and gentlemen, we are here to get to know each other and have fun. There on the dining table, there is a tray with condoms, please use them. There’s plenty of beer in the fridge, so help yourself if you are thirsty. Be free to do what you want. Tonight, we are young and free and wild.”

We all expressed our agreement with a wild scream. Matt proceeded to tell us we had to remove our clothes, and then he gave each other a number. Guys received odd numbers and girls even numbers. Apart from my four friends and my sister, there were four other guys and four more girls.

Once we were all naked, Matt brought two bags. He explained he was going to draft numbers from the bags to match odd and even numbers. He also said we had fifteen minutes to share with the assigned person, and then we were free to do what we wanted to.

Matt picked the numbers, and we were all assigned couples. Mine was a nice, kind of chubby girl with tan skin, Latino traits, and big boobs. She said her name was Natasha. My sister was joined by a tall muscular black guy with a huge thick cock. They moved to a sofa, where my sister sat. The guy kneeled on the floor and began eating her pussy.

Natasha and I lay on the floor in a sixty-nine position.  I grabbed a cushion and set my head there. Natasha got on top of me, and while I licked her tasty pussy, she sucked my cock softly and slowly. I tried to look around and noticed everybody was taking care of each other.

After three minutes, we stood up. I brought Natasha toward the fireplace, made her place her hands on the wall for support, and introduced my penis in her pussy. As I began to thrust, I got hold of her big boobs, and squeezed them gently.

I looked around and saw my sister lying on the couch while the black guy was kneeling holding her thighs as he fucked her. She seemed to be very aroused.

Alejandra was being fucked doggy-style by a short thin guy, and Joanna was lying on the carpet with an Asian guy on top of her, fucking her very fast. Matt was entertained with a short thin blonde girl with small tits who was sitting sucking his cock.

Everybody was fucking and having a good time. My partner, Natasha, was exquisite. Her huge boobs bounced back and forth when I didn’t hold them, and her pussy was so tight that I felt like coming a couple of times. At those moments, I had to slow down a little and even take my dick out of her pussy. Anyway, I guess the blue pill I had taken an hour before was going to be a big help.

After a while, Matt’s stopwatch beeped. He stopped fucking the petite blonde, stood up, and told us to listen to him.

“Hey, guys. Our warm-up has finished. From now on, do what you want, join who you want to fuck, and have fun!”

I caressed Natasha’s jugs one more time and moved toward the girl who had come with the black guy. She was black, too, and had an amazing body with a round big ass and firm medium-sized boobs. I approached her, she greeted me, grabbed my cock, and asked my name. I told her my name was Andrew, and she said hers was Selena.

Selena stroked my cock a couple of times while I fingered her wet cunt. I turned my head and saw Matt and Joanna kissing another girl, a tall, short-haired blonde with big bell shape boobs, who I had seen at our university. I also saw my sister with the Asian guy and a Mexican dude who was caressing her while she grabbed their dicks.

Selena and I touched each other and kissed, and then I asked her where she wanted to fuck. She proposed to screw on the table, so we went there while I hugged her from behind and touched her amazing tits. She lay on the dining table with my help, I grabbed a condom, put it on, stood in front of her, rubbed her clit, and fingered her for a minute, and then I penetrated her pussy, which happened to be tighter than Natasha’s. It felt so fucking good. Selena spread her legs wide and I pushed hard.

I touched her delicious tits and bent my trunk to suck her thick erect dark nipples. She was so hot! After a while, she wrapped my waist with her strong legs and made me push harder. I did, and in a couple of seconds she had an explosive orgasm.

I slowed down, almost stopped, so that she could rest for a second. Then, I took my dick out and went down on her. I began eating her pussy, and immediately her legs go so tense that she began shaking making way to a second orgasm. That was so arousing.

I jumped onto the table, landed on my knees, and crawled until my cock reached her mouth. She removed my condom and began sucking it with strong and fast movements.

On my left, some meters away from where I was, Valentina lay on her side on the couch with the Asian guy behind her fucking her pussy. The Mexican guy was standing next to them. He was bending his knees a little bit so that she could suck his cock.

Matt was on the floor with Joanna, who was sitting on his face while the tall busty blonde rode his dick. The black guy was banging Alejandra, who was lying on a couch while the guy was standing thrusting really hard as Alejandra screamed frenetically. At some point, I noticed the guy came on her belly, and as if nothing had happened, after just a couple of seconds, he penetrated her again and kept moving inside her pussy.

Selena kept sucking my dick, and at some point, I had to tell her to stop because I felt I was coming.

“Do you wanna change partners?” she asked me.

“Sure thing,” I replied.

I stood up and got close to the blonde who was riding Matt’s dick, the busty one. Right after she saw me, she took my hard cock and put it in her mouth. I touched her nice big bell-shaped tits and made them bounce. Joanna was moaning louder now, and after a couple of seconds, she came and dripped some liquid on Matt’s face. Joanna stood up, walked slowly toward the Mexican guy, kneeled down, took his dick, kissed my sister, and began sucking the guy’s cock.

At that moment, the Asian guy took his dick out of my sister’s cunt, removed his condom and released a stream of cum on my sister’s belly. The pressure was so strong that it even reached her chin. Valentina sat down, tried to remove the semen from her body, and walked towards the short guy who was on top of Selena fucking her on the floor.

She sat on the carpet next to them and began touching Selena’s firm boobs and the guy’s back, starting with his neck until she reached his ass. She introduced her hand through the line that separated both cheeks and began caressing his balls and anus.

The guy immediately stopped, moved to my sister’s side, touched her juicy boobs, and tasted them. Matt had left a mattress on one side of the living room, so this guy took Valentina there, and pushed her back gently. Now she was lying on the mattress, spreading her legs, waiting for him to penetrate her. He immediately kneeled and began fucking her. Valentina screamed wildly. The petite blonde approached them, got on all fours, and began kissing my sister’s tits.

The tall blonde girl made a pause, took Matt’s dick out of her pussy, and stood up. She looked at me and told me to sit on an armchair. I sat there, and she immediately climbed and surrounded my neck with her legs inviting me to eat her cunt. My strong arms supported her back so that she would not fall.

I licked her pussy, which now had a bitter taste, I guess because of the condoms, and tried to penetrate her hole with my dick. She hissed and arched her back. She let her body fall until her head touched my dick. I kept licking her cunt until the black guy got close to us. He let his huge dick lie on the busty blonde’s forehead, so she straightened her back, made my cock get inside her pussy, and inserted his huge dick into her mouth.

I thrust while I rubbed her clit with my finger. I rubbed it rhythmically, which increased her moaning, until she came. She took the black guy’s dick out of her mouth and told him to help her stand. He gave her a hand, and as soon as she stood up, she turned, sat on my dick, again and began riding me reverse cowgirl style. The black guy walked away, and I focused on enjoying this moment with this sexy girl.

I looked around and saw Matt eating Natasha’s pussy. Alejandra had brought an inflatable mattress and was lying there with the Asian guy on top of her. The petite blonde was on all fours next to them, and she was being fucked in the ass by Daniel.

The busty blonde girl stopped and told me she wanted to go to the swimming pool for a quick dip since it was very hot in there. I stood up and went to the pool with her. She told me her name was Alexis.

Once we were there, she told me to sit on the edge. She got into the water and began sucking my erect cock. She combined this with an amazing boobjob.

After some minutes, she told me to join her as she wanted to feel my cock inside her cunt again. We got into the water, hugged, and kissed, and then, she put her legs around my waist and made me penetrate her. I screwed her rhythmically, trying to enjoy her pussy and the sensation of our bodies in the water. Her boobs were so hot, so I spent a long time with them in my mouth.

I kept thrusting, a little deeper now, and a hot sensation invaded my insides, to the point of not being able to take it anymore, and so I came. We remained there in the pool kissing for a little while and then rejoined the party.

Inside, Valentina was being fucked by the short guy. The black guy came close to them and made a gesture.  Immediately, the short guy stood up. The black guy said something to Valentina, and she nodded and smiled. The black guy sat down. Valentina leaned forward and placed her ass close to the guy’s face. Immediately, he placed his long tongue on my sister’s asshole and licked it. He did that for a while, and then he used one of his fingers to dig into her asshole. After a minute or so, he made Valentina sit on his lap, and she began to introduce his massive dick into her anus. She did it gradually until it was completely inside. Then, she began riding his cock slowly, while the short guy tried to penetrate her pussy, something he achieved after a minute or so.

Valentina was enjoying being fucked by these two strangers, and I felt happy about her. Soon, she would be mine again anyway. Only mine.

I looked around and saw the short blonde with the small tits. She was lying on another inflatable mattress with the Mexican guy on top. I kneeled down next to her and caressed her face with my flaccid dick. She turned her face right away, stuck her tongue out and licked my tip. Within a couple of seconds, my weak cock turned into a hard bar again.

The Mexican dude stopped thrusting, stood up, and joined my sister’s party. He grabbed my sister’s hair gently, removed his condom, and made her suck his thin cock. She gobbled his shaft frenetically, while the other two guys filled her holes. It took her less than a minute to make the guy come. My sister swallowed his cum, while some drops went down her chest.

The short blonde girl stopped sucking my dick and told me to penetrate her. I told her to lie on all fours. She moved next to a couch and put her hands on the base for support. I went behind her and put my dick into her super wet pussy. It was ultra humid as if it were a deep well. Although her boobs were kind of small, they felt nice, plus, the girl was cute. She said her name was Geena. I thrust for a while, and then I began fingering her asshole. After a minute, she asked me if I wanted to fuck her little hole. I was surprised, but I did feel like fucking some anuses before the night ended.

I put the tip of my cock on the base of her asshole. I put some of her pussy wetness into the tiny hole and began pushing. In less than a minute I was already inside.

Matt lay on the carpet next to us, and Alejandra sat on top of him. She looked so gorgeous. She started riding his cock at a fast pace. I touched her cute boobs, and she bent and kissed me.

At that moment, I saw the Mexican guy moving around with a cell phone as if he was recording the live action. I told Matt, and he told me to chill out because he was a good friend of his, and he would not do anything with the footage or photos. I looked at the guy again and wanted to tell him to stop recording, but a sweet kiss from Alejandra made me forget about it.

I kept moving inside Geena. I touched her small tits and pressed her delicious taut nipples. I kept pushing my cock inside her tight hole. I was in heaven.

Alejandra kept riding Matt, and at the same time, got hold of my balls, pressing them gently. I kissed her again, and that was the moment when I came for the second time.

I lay down and Geena told me to eat her pussy. She sat on my face, and I used my magic tongue to give her a couple of successive orgasms. Then, she lay next to me, and so did Alejandra, who had also had an orgasm. Alejandra hugged me and kissed me passionately.

In front of us, my sister was still being double fucked, only that now the short guy was fucking her ass while the Mexican was penetrating her pussy. It seemed that the black guy had already come (inside her ass, I guess).

I stood up, joined them, caressed my sister’s hair, who immediately grabbed my cock and put it in her mouth. Soon, my cock was semi-hard, so I told the Mexican guy to move. He stepped aside and put his cock on my sister’s hand, who stroked it gently. I went inside her pussy and thrust a little bit.

I couldn’t keep it up for so long though, and so, I came again, this time inside my sister’s pussy.

Some seconds later, the short guy increased the pace and uttered a loud roar, a signal that he had come, too. For the first time, my sister seemed tired. She stood up and went to the dining table to grab a beer.

I was exhausted too, so I joined my friends. Most of them were now chilling out after this frenetic session, sharing some drinks and talking. My sister joined us and sat next to me. Some of the guys, especially the guests, went to the pool area and continued the orgy outdoors. Daniel and the Mexican guy came to the living room a couple of times and insisted on us going outside. They especially wanted my sister to be there, but we all said we needed a rest. Thus, we spent some time there just chilling and talking while I caressed my sister’s boobs, and she stroked my cock.

We spent the rest of the night listening to music, talking, drinking a lot, and soon many of us were drunk. Some of the guests left, and others passed out in the living room.

At 5 am, Alejandra told me to go to her bedroom. I went to bed with her. We kissed for a while, but we were too tired to have sex again.

The next day, I woke up around 8:30 am because I couldn’t sleep anymore, even though I had gone to bed very late. I walked around the house. The whole place was a total mess. Nobody was around, so I supposed all the guests had left. I decided to go to my room, but Valentina wasn’t there.

I sneaked into some rooms and finally found her lying on one of the beds, her big tits uncovered. Behind her were Matt, Joanna, and the black guy. I wondered if they had had a final sex session after I had gone to bed.

I went to the kitchen, grabbed a bottle of water, and took a sip. I had a terrible hangover, so I decided to go to the poolside and lie on one of the pool chairs to have a rest.

It had been a crazy night, without any doubt. All restrictions and inhibitions had been left behind, and we had enjoyed each other’s bodies and sex.

Our lustful trip was coming to an end. Soon, a new year of college would be starting, and I wondered what I would do with my life. I mean, I could not continue fucking my sister and my friends forever. I was going to grow up, and I had to get a life. Well, at some point. For now, I was going to enjoy these crazy moments.
