My revenge from Carla

In my last story I told how my ex-wife induced my girlfriend to cheat on me. Let's give people names: My name is Carlos (fictitious), I am a lawyer, 36 years old, 1.70 meters tall, good looks but no athletic physique. My former wife is called Carla, a young nymphomaniac of 26, law student with the appearance of an adolescent girl like ninfa, short, brunette (or almost mulatto) curly hair, only nice in face, but with a perfect body, small and hard breasts and very large, rigid and steep ass. My current girlfriend's name is Sandra, a 29-year-old attorney, beautiful, light brown, short and petite. And finally "Ricardão" has the name of Marcos (Marquinho for those who are close to him), a tall skinny black man looking like a basketball player with 26 years old and an exaggerated dowry of 26 cm. He is Carla's boyfriend, also brother of Julio, which in turn is godson of my parents and childhood friend.
I learned about the betrayal from Carla herself, who sent me by e-mail photos of the suruba in which she, Sandra, Marcos and Júlio participated. This revelation led to a big fight between Sandra and myself. We even exchanged some pushes, but we managed to understand each other. She swore that she would never cheat on me again, and it was a moment of weakness. Afterwards they stopped talking (but still work in the same office).
It seemed that we had succeeded, until on October 3, we went to my father's birthday barbecue. There were Julio (who is his godson), Marcos, Carla and her sister Cida. In the story "second betrayal of Carla" I already mentioned about Cida . She is the whitest and shortest of the three sisters (1.49 meters tall) as well as being the most naughty too (obviously more offered than Carla). She's betrothed, but she betrays the poor man with everything he is in front of everyone.
Well, we arrived at the party and everyone was already there. There were so many people that no more chairs to sit on. We stood for a while until Julio's father asked me to go to his house to get some plastic chairs (in my parents same street). He told me where they stayed and he said I should bring as much as possible because other people could still come.
I was picking up chairs in Julio's backyard when I heard a noise coming from the kitchen. I looked out of my glass window and saw Cida stretching to reach the door above the kitchen cabinet. I thought about offering to help, but then Mark came quietly into the kitchen; he leaned behind her who let out a scream of fright. He smiled at him and she scolded him by pushing him away. He asked what she was doing there, and she replied that his mother (Mark's) had told her to go get a can of soybean oil. Mark took a step forward, pressing it against the kitchen sink; he reached out his hand and grabbed for the can. She pushed him again and reprimanded him.
If Carla sees this, she'll kill me.
She's not jealous.
She already warned me not to get too close with you.
"Well, I'd like a little more privacy.
"If that's all Carla said, I would love to but I can't", she says as she pushes him away and looks at his shorts.
She was clearly excited, but she left quickly. I had been peering out of the window and preparing to go back into the chairs when I heard Sandra's voice.
Marcos, have you seen Carlos around? He said he was coming here.
No, I didn't see no.
Carlos doesn't want me talking to you, after that whole thing Carla pulled.
Carla really hesitated, but we don't have to stop talking about it.
"No, of course not. You haven't done much", she said as she stepped back to walk away.
He pulled her by the arms against his body, and pushed her up against the wall in a place where I could no longer see but only hear their voices and their shadows cast on the floor.
"Didn't I do anything too much?" he said seductively.
Carlos could be here any minute.
- Says he didn't like it, says he doesn't want any more.
Oh, my God.
I heard the sound of gasping breaths and kissing noises that lasted about five to 10 seconds.
I'm not used to a stick that big.
After that, there were about five minutes of moaning and the sound of bodies beating. Marcos announced he was going to make fun. There was silence for a few seconds until Sandra asked him to put her on the floor. Then I heard his feet banging against the ground. She should have been hanging in his lap.
"This time you joked too fast. You didn't even give me a chance to joke".
- If you want, we can stay here all afternoon.
No, of course not that's crazy someone could have seen us but you owe me and I will collect i want more from this break
- And when will I see you again?
"I'll call you next week. I will find a way to get Carlos". She said maliciously.
And then they left, and I waited a little bit longer, grabbed about six chairs and went back to the party.
Your girlfriend just showed up with my boyfriend, and I wonder what they were doing.
- I don't know, ask your boyfriend.
I only stayed for another 30 minutes at the party. This situation bothered me so much that I left right away, took Sandra with me and we ended our relationship on the same day. She didn't say anything about what she had seen but just said there was no more to be done.
The story could have ended here, had it not been for the happy coincidence that I found Cida walking home alone on my way back from Sandra's house. An idea came to me quickly: this might be a chance to get revenge against Carla. I parked the car next to her and offered her a ride. I figured she could still refuse but never mind. She immediately accepted and got in the car. I asked why she was coming home so early and by herself. She replied that she had become bored with Carla because of jealousy over some joke Marcos made about her. So I invited her over to my house for a couple of beers and continued the conversation.
And it was just as easy, after a couple of beers that we started kissing. I took off her clothes without any resistance on her part. Then I could see her spectacular body: very thin but with everything in place, impeccable proportions, rigid flesh like a teenager's. I came to think she was hotter than maybe Carla. No, I don't know. They are both perfect and how well she fucks! We had sex right there on the couch at home where we were. Cida showed that she knows about oral sex almost getting me an orgasm within the first few minutes from the best blowjob I ever got. I warned her that she couldn't resist. She then pulled a condom out of the pocket and dressed me with her mouth, then went on all fours. She rolled around masterfully and compressed my vaginal muscles almost strangling my cock, which became hard as rock. I could not hold it for more than 5 minutes, enjoyed myself. I sat down to rest but Cida did not give me any respite. He put my whole dick in his mouth (everything anyway), still half-hard, half-soft, swallowing all the shit he had therein. Sucked very strongly until it started puffing up again. When I felt the head of the bowl go past the starches. I thought, "What girl is this?! She's better than her sister". I was impressed by such a skill. My dick ended up hard right away. I could feel it going through Cida's throat. Not that my cock is so big -- 18 centimeters long -- but we are talking about Cida who is less than 1.5 meters tall. When that happened, she seemed to like it even more.
All of a sudden, her phone started ringing. She warned me that it was her fiancé on the telephone and she began to roll over slowly while I talked with him on the phone explaining where he was etc., then told him to wait because there was another call waiting. Then put his cellphone in "mudo" and exploded in deep joy shaking my whole body and wetting my lap. She quickly recovered and went back to talking to her fiance telling him that she was a friend on the line and kept chatting for about two minutes as if nothing had happened. When I hung up, I could tell she was even more aroused... as if the pleasure of betrayal were greater than sex.
We lay on the living room floor, exhausted. I had never thought that Cida, so tiny, such a little girl, could be this devious. After one minute she stood over me and opened her legs and let the rest of my cock fall from its vagina onto my chest. She sat down upon it and rubbed her cheek against it licking my breasts and belly with my sperm. Then to my amazement, she looked at me in extreme malice as if possessed, and (still sitting on my breast) started urinating. I reacted to get up, but she held my shoulders without any force, just gesturing for me to be still. I let it roll. It oddly aroused me. She kept looking at me in the eyes with that malicious expression, reached her hand over to my penis and squeezed it to check on my erection. I was surprised because I don't remember ever having such an immediate erection after orgasm. But there I was lying pissing, a little nympho sitting on my chest and sticking out hard after playing twice.
She then slid slowly until she sat on my dick, rubbing her pissy little cheek all over my belly. Looked at me with an extremely exciting smile. Grabbed hold of my cock and guided it to the ass. It was sitting down slowly. He closed his eyes and felt my penis coming in. Not difficult. It is clear that he had already been having anal sex quite frequently. Started a very nice ups-and-down while masturbating. The scene was wonderful. I lifted myself up and put the foursome on the couch. She asked him to fuck her hard and I answered. I ate this cuisine as violently as possible. But she kept asking for more, and after a few minutes of that, she started laughing at me... but I could only hold my orgasm back long enough to make her laugh.
We took a shower and I drove her home. The rest of the day, I was thinking about that fuckin' thing. Thought if I had photographed that trance then maybe I could send those pictures to Carla. It would be a good way for me to get back at myself. But I missed my chance. So I called Cida the next day asking her out again. She refused. Said she was engaged and couldn't go on dating me anymore. I took the pictures that were meant, but ended up saving them to send later.
