I witnessed Carla's betrayal.

First of all, let me describe you: I'll call myself Carlos (the names are fictitious); I'm a lawyer; 35 years old, 1.70 meters tall, and good-looking, although not the type <unk>sarado<unk>; my wife, Carla, is much younger, 25 years old, has now graduated in law, but still does not work. Although not so pretty in the face (just nice), she is really very sexy, like a little girl, short, dark jambo (or mulata), curly hair, teenage breasts and a big ass (spectacular and perfect!), and really attracts the attention of men and the envy of women wherever she goes. The story I am about to relate took place in January 2009, when we stayed for a week in a vacation camp in the interior of the state of Rio de Janeiro. Well, we went to this vacation camp with two other couples of friends, whom I will call André (28 years old) and Andréia (26), and Beto (33) and Bia (30). We arranged to meet at a road stop and went by caravan to our destination. It happens that Beto, whenever he goes on vacation, carries his mother-in-law with them, and. this time, to my disgrace (or maybe not), he also took Bia's brother with them. Arriving there, we were introduced to them. Beto's brother-in-law is named Ricardo (real name), he is 27 years old, about 1m 90 tall, dark, really very handsome in face and with an impeccable body, quite strong and athletic. I learned that his girlfriend would also go, but due to a last-minute fight, he decided not to go. In the course of the presentations, I paid close attention to Carla's reaction, because it was inevitable to feel a little insecure around the boy who looked more like a model. She, on the other hand, showed no interest, was only polite. That immediately reassured me. In fact, I was never jealous, I always felt quite confident about our relationship and the fidelity of the young woman, but the presence of that young man bothered me. The next day, we all went to the pool. It was a cloudy day. Besides us there was only a boy accompanied by his mother, but they were in the part reserved for the children. Beto, André and I were next to the pool, next to a barbecue, roasting meat and drinking beer. The mother-in-law was sitting on the edge, just wetting her feet. Carla, Bia, Andrea and Ricardo were in the water, playing "bobinho" (a game with a volleyball or football). I began to worry again, because I noticed that every time Carla was with the ball, Ricardo surrounded her with his arms and sometimes even embraced her under the pretext of taking the ball from her. It seems that Beto understood my fear, because he called Ricardo to join us. Ricardo only looked with a sad face. The women immediately interceded, asking him to stay in the game. He smiled and returned to play. Carla, this time was in charge of taking the ball from the other participants. Each participant threw the ball to the other when Carla approached, except Ricardo, who used his great stature to prevent her from reaching her. He raised his arms and Carla stood in front of him, resting his arms on Ricardo's chest and shoulders. Her body stretched in his eyes, everyone seemed to notice no harm. I tried to talk more with André and Beto so as not to show my distress. Even because it was not in my nature to be jealous. Sometimes, when the laughter was very exaggerated, I looked at them and pretended to find all this mess they were making funny. In one of my glances, I saw Ricardo with his hands raised, holding the ball, with his back to the women. Carla, behind him, struggled to get it, jumped and leaned her breasts on his back. After the thought, I saw one of her hands jump through the boy's sarcastic abdomen, stopping at the height of his swing. It was for a fraction of a second, but I can swear that I saw a volume on the swing. It was not possible to be sure. The water was only a little below the height of his navel, two centimeters above the boy's navel. The two boys with the illness followed each other as if nothing had happened. Ten minutes later, Ricardo's mother asked him to go to the room and get a sunscreen for her. He immediately agreed. At that moment, Carla interrupted: she told the lady that Ricardo did not need to go, because she would already have to get a sunscreen for me, and that we could share the same sunscreen. She still smiled and said that I was a false brunette and that I would get all burned by the strong sun; that she was quite brunette and was not in such danger. The lady agreed and thanked the kindness. Carla then came out of the pool with an enviable butt in a tiny bikini. Ricardo asked her to wait for him, because he would have to go up to the room to call his girlfriend. They went together. The pool is in a lower part of the plot, which looks like a valley. To get to the apartments you have to climb a staircase, ten meters above there is a cobblestone street, crossing that street, you reach the apartment building where we stayed. I kept looking at them until they disappeared. Carla was so small near Ricardo, I could barely reach his shoulders! My mind was torturing me. I could barely disengage. I figured it was time to take my medicine and I said I would go up, but I would come back soon. André then asked: I didn't say anything, just smiled. I went up the stairs in a hurry; I ran across the street; but I didn't enter the building, I went around it. Right behind the building a hill already begins, so at the back of the building there is only a ravine and a forest. My room was on the first floor and had no view to the pool but to the ravine. Richard's room was on the third floor, if something happened there, I wouldn't know. But to my luck (luck!), they were in a hurry, and then they went to our room. Even before I peeped out the window, I could hear both of them breathing heavily, the sound of kisses. They were even talking. I only heard one say: I'd like that very much. "Me too", the other replied. I still can't describe the feeling I had at that moment. For one second I thought I was going to faint, the next I felt like throwing up, the third I felt a mixture of sadness, disappointment, jealousy, anger and passion. That's right: I was excited about it. I was surprised by myself. So I decided to peek in, and Carla was pulling his penis out of the swing, and all she said was, Oh, my gosh! He just grinned maliciously, he was a jealous cunt, he must have been about 22 centimeters, Carla's hand, tiny, couldn't even close on that cock, she made like she was going to suck, but she only gave one kiss. "We don't have time, let's go". She said, getting into bed. I moved away from the window so they wouldn't see me. Then I peeked back. They were too busy to think about the open window, where there was only bush and ravine. Ricardo went over to her. When the bastard came in, she said: Oh, my God, it's really great! Oh, how delicious! He started a slow, but firm, strong back and forth movement. He seemed to be shoving all that shit into Carla's "teenage" sketch. She let out a restrained groan with every incoming movement. I seemed to be feeling her hard-on. It was a huge hard-on. I didn't know how I was going to deal with it in the future, but I was seeing my wife, really, delighting in another man, as female and as excited as I hadn't seen her in a long time. It didn't take five minutes and the strokes were already faster and more violent. Carla groaned loudly, and begged not to stop. She was already announcing a joy that didn't take long to arrive. By the sound of the strokes it was possible to tell that she was full. She groaned and twisted like never before. I've never seen Carla enjoy so quickly. I'm used to seeing her mock three, four, six times, until that orgasm convinced me of that boy's lightning. He smiled with satisfaction at seeing her so delivered and so ecstatic, and went back to concentrating on the strokes, but she interrupted him: We've been here too long, Carlos is going to get suspicious. He still protested that he hadn't joked, and Carla grabbed his face and said, I know, my angel, but we still have five more days to make out together. Another time I'll give you the reward. Let's not spoil everything in one go. I still want more of that tasty stick. They kissed, he put on his sunglasses in a hurry and left. He must have gone up to his room. Carla got dressed, took the sunscreen and left right away. I ran to meet her in front of the building. I asked angrily the reason for the delay. She said that she took the opportunity to rest a little because of the heat. We went back to the pool together. And Ricardo returned about 15 minutes later. For the rest of the week, Carla must have kept her reward promise to Ricardo, because three times, on three different days, the two of them disappeared for a while. Then they came up with ridiculous excuses that didn't convince me. I couldn't spy on them, but I'm sure they had a lot more sex than I did that week. What if my marriage is over?
