I knew my girlfriend Sarah was a slut from the start. I met her randomly on instagram after i sent her a request. She is 5’4, blonde hair, she has big beautiful boobs and a round butt. It took me three days of chatting with her to get inside her pants. I was sure she was meeting other dudes also but I didn’t care. About a month later we decided to get together. She was 21 at the time while I was 24.
Sarah was the kind of girl who loved to be dominated in bed, she has no gag reflex and she is amazing with deepthroat. Our first month together we used to have sex all day. She was kind of a nymphomaniac as she would ask me for sex even 10 minutes after we finished. At the beginning this was great but as time went by it became a bit too much for me. I always fantasised about cuckolding and more specifically for my girlfriend to be a total slut and being used by bigger men. When I met Sarah and got to know how crazy she was in bed and how much she loved sex I said to my self Bingo.
I started discussing sexual ideas with her in bed and it didn’t took long for her to admit that she would love to be fucked by other dudes and why not even try it with more than one guy at the time. I was super exited about this. In the next 5 months Sarah had sex with three other dudes, but I only heard her stories and got videos of the action.
We moved together in a small apartment which was not that great but we didn’t have much money at the time since I was the only one working. Our landlord lived one floor down from us and every first day of the month he would come to take the rent money. I started to hate that man from the first week there because he was very arrogant and rude. He only cared about the money and when we had problems with furniture and stuff he never wanted to fix them.
Bob, our landlord was a man in his early fifties. Physically he was huge, probably around 6’4 and a bit overweight. I never argued much with him because he was kind of scary, but the thing that annoyed me the most was how he started my girlfriend any chance he had.
Since me and my girlfriend were always trying to find new existing sexual ideas, one night when she was a bit tipsy she told me to imagine Bob fucking her. She created a scenario where we didn’t have money to pay rent and she would submit to him so that he would not kick us out. Although I hate that man, the image I was creating in my head made my dick hard as a rock. This fantasies went on for a couple of weeks and one night we decided to tease him a little.
We knew Bob always came the first day of the month to collect the rent money so we decided that this time Sarah would open the door in her panties. When Bob rang the door around 8 am Sarah followed the plan, she was wearing some pink panties and a short t-shirt. She opened the door while I waited in the bedroom. She made sure to chat with him a bit before giving him the money. As she told me later, Bob really enjoyed the view and looked like he didn’t wanted to leave.
In the next few day Sarah called him a with the excuse that the fridge wasn’t working (which wasn’t working that well since we moved there). After Bob looked at the fridge she offered him something to drink and they both sat on the sofa. I waited in the bedroom while all this happened. Sarah in full acting mode asked him if we had to pay for it and that we were not in a very good financial situation at the moment. Bob took the opportunity and told her that we could always find a way. Sarah thanked him and slowly caressed him arm. She could see the smile on his face and decided to lower her hand. She started caressing his legs while Bob followed by putting his hand between her legs. Sarah decided it was enough for that day and told him it was time to leave.
A couple of days later a technician came to fix the fridge. Bob came with him and after he finished Bob payed him. As the technician left Sarah approached Bob and thanked him. She then fell down on her knees looking him in the eyes and told him she wanted to pay our part. Bob looked so confused since I was also there.
I didn’t say anything and a seconds later he slowly unzipped his pants and pulled out his cock. He wasn’t hard at the moment but his cock was already my length and much thicker. Sarah started playing with it a bit before putting it in her mouth. She sucked his cock very passionately and it didn’t take long for it to become hard. His cock was the biggest I had ever seen. It was at least 9 inches long and super thick.
It was the first time for me watching my girlfriend suck another man’s cock. I felt very embarrassed by the situation and by the fact his cock was much much bigger than mine. Sarah complimented his size telling him that his was by far the biggest she has ever tried. Bob was standing there at the door while my girlfriend was working her magic. She started talking it as soon as she could. At one point Bob started calling her a slut and pushed her to take his cock even deeper.
She sucked his cock for some minutes until Bob told her he was curious to see her pussy. Sarah smiled, turned her eyes at me waiting for some kind of reaction. I just froze there like a statue trying not to cum in my pants. Sarah stood up and slowly moved to the sofa, she turned in a doggy position and told Bob to join her. Bob didn’t think twice about it and immediately pulled down her shorts and panties. He sat on his knees and started licking her ass and pussy. I could see him enjoying that moment as I was sure he had thought about it many times.
He ate her pussy from behind for a couple of minutes before getting up and putting himself in position to fuck her. Sarah told him to go slow as she had never tried one that big. He started rubbing his cock on her pussy before slowly putting it in. I could see my girlfriend’s mouth opening wide as his dick was going in. She started to moan pretty loudly while his cock was not all in yet. Bob started fucking her slowly for some time and then little by little he increased the rhythm.
The view of my girlfriend getting fucked by a man twice her size was amazing. He started fucking her harder while Sarah was screaming. He fucked her like that for about five minutes before he pulled his dick out and came all over her lower back and butt. Sarah lied down on her stomach catching her breath as Bob smiled at me telling me my girlfriend did a great job paying him. I felt humiliated but at the same time super horny. Bob left shortly after leaving us alone.
As soon as he closed the door I pulled out my cock and approached the sofa. Sarah looked at me with a smile while I tried to pull my cock out. I would have loved to fuck her right there but the excitement was too much, I jerked my dick off for a couple of seconds and shoot a load all over her face. She laughed about it and told me it was amazing. She stood up from the sofa heading for the bathroom. I stopped her before she could do so, got down on my knees and started eating her pussy. It was so wet and warm I loved it.
The cum was dripping from her face and back but I didn’t care. I ate her pussy for less than a minute before her legs started shaking and she had an orgasm. That was by far the most amazing sexual experience we ever had up until that point.
