Vacations, beach and cuckolding with my girlfriend.

Mariana is my girlfriend, she's one of those dark-haired girls that make you turn around to look at her on the street. Thin, medium height, very pretty Booty, normal-sized tits, nice face.

We've been together for more than 7 years and about 2 years ago we started practicing cuckoldry.

We had an excellent first experience that almost didn't plan itself (here's the link to the report of that experience)http://www.poringa.net/posts/relatos/3084384/Mi-novia-y-su-primer-amante-experiencia-real.html) and since then we've had a few more experiences. In most cases these experiences are quite simple although not for that less gratifying, but they're about her going out with some ex-boyfriend, some acquaintance, someone who's into her, we'll go get something to eat, then to a hotel and that's it all over. But this experience I'm about to tell you has several details that take it out of the ordinary and make it quite interesting. In February of this year, both of us went on vacation from work. To not make the story too long and focus on the important parts, I'll get straight to it, we decided to go to Brazil, got a place in Buzios and hit the road. We arrived and the first three days were normal... beach, walk around, go out for something to eat at night... usual stuff. Neither of us knew Brazil, and Mariana was thrilled with two things; beaches and blacks. She had always fantasized about being with a black guy. The truth is she tried to hit on two or three guys we had some conversation with but it didn't work out. Mulattoes didn't catch the vibe we had. One afternoon while at the beach, we met an Argentine, a skinny guy around 32 years old, named Marcos, who had lived in Rio de Janeiro for a while and taken a break to visit Buzios. We spent the afternoon together on the beach and agreed to meet up that night to go out. Mariana liked him. That night we went out the three of us, but nothing happened, Mariana tried to hit on him but it all stayed at that. With Mariana, we knew there was a nude beach, and she came up with the idea to invite him to join us the next day. We messaged each other that same night and agreed to meet up the next day. We had agreed with Mariana that I would try to leave them alone for as long as possible, so she could hit on him and if he seemed interested, I'd tell her about our relationship. tomorrow Mariana will shave her pussy well and put on a white bikini that looks spectacular. We'll go looking for it, asking questions until we arrive at the secluded nudist beach that's a bit of a walk from here.

We arrived, the beach wasn't very big, about 200 meters long, there were quite a few people but not too many, you could sit pretty far away from others.

We chatted for a while, had a couple of beers, Mariana was still wearing her bikini.

We had left the sunscreen in the car on purpose and Mariana asked me to go get it.

When I got back, Mariana had already taken off the top part of her bikini and we were chatting, sitting on the sand.

I told them I was going to the water and left them alone.

I stayed fooling around in the water doing snorkeling about 50 meters away from them for a while. Later when I looked back, Mariana was lying face down on the towel with Marcos rubbing sunscreen on her back. It seemed like things were going well.

I went back, sat down, and we kept talking. She said her nipples were burning from the sun and put two nipple shields on.

Half an hour later Mariana said she was going to the water and asked who would accompany her.

I didn't say anything, Marcos didn't either, so she told him: 'Come on, Marcos, come with me!'

Mariana quickly took off the bottom part of her bikini and turned towards the water with Marcos by her side. The skinny guy didn't dare take off his Bermuda shorts.

We fooled around in the water for a bit and suddenly I saw them embracing and starting to kiss. They were like that for about 10 minutes. After that she got out of the water and came over to where I was.

She told me she had already said what our vibe was, at first it seemed surprising but then it relaxed. She said she'd touched me badly in the water.

Mariana stayed naked and lay down next to me to take some sun. Later Marcos showed up and we started chatting nonsense. We stayed until 7. Mariana put on her bikini, and in the car she changed right in front of us, putting on a thong, a jean mini-skirt, and a sleeveless shirt. We went to get something to drink and then left him where he was stopping. Mariana was really hot, she told me that she had put her fingers forward and backward when they were in the water. That night we got it all. She wanted to do it with Marcos but it was kind of complicated, he was staying at a family house, and at the inn where we were staying we couldn't make him enter. The next day it was pretty much the same, nude beach, Mariana was naked, Marcos was more confident and put his hand on me in front of her while I was putting on sunscreen, they both went into the water naked, franeleo.......and when they came back Mariana told me to give her the car keys, that she would go get the towels we had left there, and see if we could do something in the car that we had left in a somewhat hidden place or if we got lost among the abundant vegetation. They took about an hour and a half. It was already late so we left Marcos at his house and went back to the inn. Mariana told me she had sucked his cock in the car, that she had made him cum, but they couldn't do it there. So they went about 50 meters into the vegetation, where she got naked and he screwed her in several positions on the towel. The next day the plan was to do something similar but it rained all day and the weather was really bad. The other day Marcos was going back to Rio and we couldn't concretize other encounters. We left his number and the promise of trying to arrange something someday to meet up again in BS.
