My sister-in-law on the nude beach - part 1

At that time, I was 19 years old, and my girlfriend, Isabela, and I had been together for a little over a year, and her sister, Carolina, had always been a constant presence in our lives, and Carolina, who was 18 years old, was only a year younger than me, and from the very beginning, I noticed something different in the way she looked at me. There was another occasion that left me even more confused. We were all in the room - me, Isabela and Carolina. Carolina was wearing a short skirt, and when she bent down to pick up something on the floor, it seemed like she was doing it on purpose. She had no panties, and her butt was completely exposed, right in my face that fleshy little finger is her pink ass. This happened right in front of Isabela, who didn't notice anything. These moments made me restless, but I had never done anything about it. Once, Carolina had suggested a trail that led to a beach, and she knew the path very well, and Isabela was excited about the idea of spending the day outdoors, so the three of us agreed to go. However, on the day of the trail, early in the morning, Isabela received an urgent call from the internship asking her to cover for a colleague who was missing. <unk> I think we'd better cancel, so <unk> I said, as I watched her hurriedly pack. Isabela shook her head, smiling. No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, not not not not not not not not not not not not not not not not not not this is not not not this is not not this is not this is not not But... there's no point in going without you, Isa. I insisted. She put the bag on her shoulder and came over, giving me a quick kiss. You'll have fun, and besides, Carol knows the way. I hesitated, but I knew that Isabela didn't think it was wrong to leave her sister with me, and deep down, I wanted to go too, and the beach seemed like a good idea. It's okay, I finally agreed. I'll go with her, then. <unk> Thank you, love <unk> she smiled, already leaving the door. <unk> Send me pictures later! I finished dressing shortly thereafter, wearing a black thong under a bermuda, and the heat was unbearable, so I tied a T-shirt to my backpack, knowing that I would only need it for the return trip. When Carolina appeared, ready for the trail, my heart raced slightly. She was wearing only a dental floss bikini, which was so small that it barely covered her cheekbones, and I could clearly see the outlines of her lips through the thin fabric, and the white thong tied loosely around her waist. She was short, with red hair that contrasted with her light skin. Her breasts were small, but her nipples were clearly visible through the bikini. On the way, we stopped at a little market to buy a few things, and we got some biscuits, a few bottles of water, and, of course, some beers to cool off on the trail, and Carolina was excited, and I was trying to keep the conversation casual. Arriving at the trail, she took the lead, saying that she knew the way well. I followed her, letting her guide me. As we walked, we talked about trivial things: the weather, the beach, college. But, in fact, I hardly paid attention to what she said. My focus was elsewhere - on the way her ass rolled at every step. The white thong that she wore was almost imperceptible under the sunlight, and the dental floss bikini seemed to disappear into the middle of her ass, accentuating her curves in a way that was impossible not to notice. Every move she made, my gaze was automatically drawn to that hypnotic swirl. "It's too hot, isn't it?" Carolina commented without looking back as we climbed a steeper part of the trail. "It's"... I answered, trying to keep my voice steady. We decided to open up a few beers to cool off, and the alcohol helped take the heat off a little bit, and halfway through, I decided to take off my bermuda because of the heat, and Carolina, who wasn't stupid, used that as an excuse to get rid of her thong. "Ah, what a relief!" she said, with a mischievous smile, as she tied her thong to her backpack. I soon regretted taking off the bermuda. My dick began to harden from seeing Carolina's practically naked ass rolling in front of me. The light mark on my thong was harder to disguise without the bermuda, and my dick, which had always been large, made a sharp protrusion. When we finally reached the end of the trail, the dense vegetation opened up, revealing the beach. The scene in front of me was truly stunning: the white sand extended to the blue sea, and the place seemed almost completely deserted. The sea breeze was refreshing. But then I saw the plaque, and right in front of us, in large, conspicuous letters, it said: "Warning: Nudism beach <unk> Forced nudism". My heart raced. I looked at Carolina in disbelief. <unk> Carolina, what the fuck is this? <unk> I asked, pointing to the board, my voice charged with surprise and irritation. <unk> Did you bring us to a fucking nudist beach? She looked at the sign for a second, and then made an expression that bordered on comical, as if she were completely surprised. <unk> Ah... what the fuck, I think I've got the wrong track... <unk> she said, without the slightest conviction, as if rehearsing the excuse. <unk> How did I get the trail mixed up? <unk> I exclaimed, now even angrier. <unk> You said you knew the fucking way! She shrugged, with that smile I knew well, a smile that indicated that none of it was really a mistake. <unk> Yes, I know, but, I don't know... I think I messed up today. <unk> She looked around, unconcerned, and then she looked at me again. <unk> But since we're here, we're not going back, right? The walk was too long for that. I was about to protest again, but the truth is that the fatigue began to hit me. The walk had really been exhausting, and the heat was absurd. Returning to the trail, at that moment, seemed like a nightmare. I looked at the sea, feeling the refreshing breeze. Maybe it would be better to rest a little right there, without entering the beach, and then we could decide what to do. <unk> Look, Gabriel, there's no point in us going back now. <unk> She continued, realizing my hesitation. <unk> The beach is beautiful and it's almost empty. Besides... <unk> She paused, giving me that provocative look. <unk> Isabela doesn't need to know. The place was beautiful, and the idea of walking all the way back seemed worse and worse. But before I could finish processing the situation, Carolina was already acting. Without thinking twice, she began to take off her clothes. She untied the bottom of the bikini and her round butt was completely exposed. Then, with the same naturalness, she began to untie the top of the bikini. "Carolina, what are you doing?" I protested again. Without stopping, she just pointed at the board with a mischievous smile. <unk> Didn't you read, Gabriel? <unk> he asked, with a voice full of provocation. <unk> "Mandatory nudity". I knew she was having fun with the situation, but I still tried to argue. <unk> That doesn't mean we need to... <unk> I started, but Carolina interrupted me with an even bolder smile. <unk> Of course it means. <unk> She laughed, already letting the top of the bikini fall next to the other. Her small but firm breasts were completely exposed, her pink, erect nipples pointed directly at me as if to provoke me, her pale skin contrasted with the redness of her hair, her face, now fully visible, was smooth and well-groomed, with fleshy lips that seemed to be calling to me. She just turned and stooped to grab the bikini off the floor, sticking her ass up and making her ass visible. Her ass was small and tight, with a soft pink skin that contrasted with the whiteness of her ass. Her already moist cheek was glowing in the sun, and I could clearly see the contours of her swollen and excited lips. I swallowed dry, trying to control my thoughts and my body. <unk> Come on, Gabriel, don't be shy. <unk> She got up and walked to the beach naturally, calling to me with a gesture. <unk> The beach is ours, and no one needs to know. I knew I had no choice, and that if I came back alone, she would find a way to make a villain out of me. I took a deep breath, trying in vain to loosen my dick before sliding the swing, making it jump out. My dick was big and thick, the pulsating veins running along its entire length. My head was pink and swollen, and my balls, heavy and full, hung down below, ready for action. I stooped down to pick up the sandbag and put it in my backpack, and I was surprised by a breeze on my ass. My butt was firm and muscular, with smooth, tanned skin. I poured the rest of the beer out of the can and then opened another one, taking half in two sips, gathering courage. Before I got up and headed for the beach, I took another deep breath, feeling the alcohol begin to take effect. The sexual tension was still unbearable, but now I was determined to face the situation. And I followed her, trying to hide my dick with my hands, without much success. Carolina made fun of me and invited me to go to the sea, but I refused, sitting on the sand next to our backpacks. "Come on, Gabriel, don't be shy", she said, with a mischievous smile, as she walked away toward the water. I just shook my head, feeling more and more uncomfortable, the sea breeze caressing my skin and I could feel every hair on my body tingling, my dick throbbing painfully, and I knew there was no hiding my excitement. Carolina turned to me, her eyes shining with desire. "You're missing the best part", she said, in a provocative tone, before diving into the crystal clear waters. I watched her as she dove, her naked body shining in the sun. I finished my beer before I could open another one and light my soda, I laid down, pulled her thong to cover my dick, and took my T-shirt to cover my face, finished smoking the tip, trying to sleep so that this moment would soon pass. The sea breeze kept caressing my skin, and the sound of the waves crashing on the beach was almost hypnotic, and I could feel the effects of alcohol and base began to relax me. I woke up with a wet feeling rising from my balls to the head of my dick, and I took my shirt off my face, and I saw Carolina licking my dick, and I tried to walk away, but the dizziness of the sunlight coupled with the effect of the marijuana helped her hold me by the waist, sliding her tongue down to my balls again, and I tried to protest, but the words didn't come out. "Carolina, what the fuck are you doing?" I finally managed to say, my voice numbed by excitement and confusion. She smiled, her eyes fixed on mine as her tongue continued to explore every inch of my cock. "Oh fuck no, I know you're eyeing my ass from back home, and you want it as much as I do, your dick doesn't deny it's hard as stone", she said, in a provocative tone, before slapping my dick, sliding her lips to the base. I cried out, unable to control my body. Before I went to bed again, I knew there was no turning back, the feeling was overwhelming, and I surrendered completely to the pleasure she was giving me, her warm, moist mouth wrapped around my dick, and I could feel every movement of her tongue, every pressure of her lips. Carolina began to move her head up and down, her lips sliding down my dick with maddening precision. With each movement, I felt a wave of pleasure sweep through my body, leaving me more and more excited. She would stop every now and then to lick the head of my dick, her tongue twirling in circles. The saliva ran down my dick, making it even more slippery and sensitive. She then lowered her tongue down to my balls, licking them gently, while her hand continued to masturbate me with steady, rhythmic movements. The feeling of her warm, moist tongue on my balls was indescribable, and I moaned with pleasure. She would stop from time to time to suck them, further increasing the intensity of the pleasure. She walked away slowly, her eyes fixed on mine, with a smile of satisfaction on her face. "You liked it, didn't you?" she asked, in a provocative tone. <unk> Very <unk> I answered, my voice charged with gratitude and desire. <unk> I even want you to suck me, but I've been wanting to sit on this stick for a long time <unk> she said, with a malicious smile. <unk> Light the base for us. I took the base and I lit it, taking a long puff before I passed it to her, and the smoke filled my lungs, and I could feel the tension starting to dissipate. "Are you ready?" she asked, in a provocative tone, as she sat on top of me. <unk> More than ready <unk> I answered, my voice charged with desire. She took her position on my dick, sliding slowly down. The feeling of her warm, wet mouth wrapping around my dick was indescribable. She started moving up and down, her big ass banging on my lap. I could feel every inch of her, every movement, every contraction. The scene of her riding on my dick, with the sea at the bottom, was wonderful. Carolina picked up the pace, her hips moving with increasing intensity. Her groans mingled with the sound of the waves crashing on the beach, creating a symphony of pleasure. I held her by the hips, guiding the ride and following the movement, punching even deeper, the pops became louder than our groans, the bands of her butt opened and closed with the movement, and I could see her ass winking with pleasure in the same rhythm as the muzzle squeezed my stick. When I was about to make fun of her, she pulled my dick out and leaned forward, and I poured on her ass, leaving her all fucking hot, and I don't think I've ever had so much fun in my life, and a roll was like a drizzle, and the sight of my dick running down her pale skin was exciting, and I felt a wave of satisfaction sweep through my body. After the transaction, Carolina lay next to me, not caring about the fucking dripping down her ass, quietly smoking base, and I, in the shock of realizing what we had done, turned to her and asked: Carolina... what have we done?
