I fucked my best friend’s pregnant girlfriend as he let me stay at his place for some days [cheating] [pregnant]

Due to some ongoing renovations at my house, I needed to find a temporary place to stay for a couple of weeks. With the added expenses of the renovations, I wanted to avoid spending a lot on a hotel. I decided to ask my best friend, Ben, if it would be alright for me to stay at his place for a few days. Ben lives with his girlfriend, Anna, who was five months pregnant at the time. I’ve known Anna for about five years, as we all went to college together. However, given her delicate condition, I was concerned about potentially disturbing them during such an important and sensitive time.

Ben and Anna thought insisted I should stay at their place and since Ben was working tow jobs and Anna was staying home Anna loved the idea of having some company those days.
The first couple of days things were pretty normal, I spent all day with Anna helping her around the house and talking.
On the third day though we had a small incident. I woke up from my afternoon nap and went to the bathroom, for a second I thought I was home alose as it was very quiet but as soon as I opened the bathroom door I was Anna completely naked in front of the mirror. She had just came out of the shower. We both froze for a second before I quickly apologised and closed the door.

I immediately run to my bedroom very nervous about what just happened. Minutes later I heard Anna was in the kitchen and I went there to apologise again. She was very understanding and told me it was an incident so it was no problem. She then made a joke about how I didn’t see her in her best form. This really broke the ice and I laughed telling her she looked amazing and that she got that pregnancy glow. She told me how she was used to leave the doors open as she was always alone and that I should bot freak out if I ever find her peeing with the door open or walk around in underwear.

I laughed telling her that after seeing her naked, seeing her in underwear would be a downgrade. She laughed and hit me on the shoulder.
The next day around 2PM I was watching tv on the sofa and Anna joined me. We watched a couple of episodes of a tv show before I crashed and fell asleep. I kinda woke up a bit later and saw Anna was sleeping right next to me. With my brain half asleep I didn’t thought much about it and just spooned at her.
It took me some seconds to realise what was going on. Annas but was pressing at my cock while I had my arm around her. The feeling of her ass started giving me a bonner. I tried to move a bit but there was no more space.

I knew I had to slowly get up and leave but unfortunately I started thinking with my small head. I slowly started rubbing my cock on her. At first I wasn’t sure if she was asleep or not, but then I felt her doing the same thing. She started rubbing her butt slowly. I took that as a yes so I started caressing her belly before putting my hand under her shirt and to her boobs. We went on like that for some time and then I decided to put my hand inside her panties. As soon as my fingers touched her pussy I could feel she was super wet.

I could tell all this was making her horny. I played with her pussy for a bit and she started moaning. After some time of doing so she stood up from the sofa, looked me in the eyes and then started undressing. I asked her if she was sure of this, but she without responding started taking off my pants and grabbed my cock. I told her to get on top of me, so she put herself in a 69 position. My god her wet pussy on my face felt so good. I started eating her pussy and she put my cock in her mouth. All this was unbelievable, I moving my tongue from her clit to her ass hole. I was feeling I was about to cum so I had to stop her. i told her to turn around and she did. She slowly put my cock inside her and she started riding my cock.

As I couldn’t resist too much longer I fucked her for a minute or so before I was ready to explode. She told me to not worry and go on, so I pushed my cock all the way inside her and came. I filled her pussy with my cum as she kept riding it for a while even after I finished.
She then put her head on my chest and we stayed like that for a while. Non of use talked for a while before she asked me if I wanted to join her in the shower.
We showered together and made out. We got so horny again that once we finished we went straight to her room and I fucked her again.

I knew all this was wrong but the idea of fucking my best friend’s pregnant girlfriend without a condom and having the chance to cum inside her was too much for me. That second time I fucked her a lot longer. Putting her in a doggy position and slapping her but until it became red.
That night when Ben came baco from work we both acted normal. It was a strange feeling and I knew the next day I would probably bang his girlfriend again. In the remaining days there I fucked her regularly. She would walk around naked, suck my cock whenever I wanted and she would also text with Ben while I was fucking her from behind.

One day I asked her If it was the first time she was cheating on Ben. She seemed a bit hesitant to respond at first but after making me promise to keep the secret she told me she had fucked 4 other guys before me.
I was very surprised to hear that as I would have never guessed. Anna was always so sweet and she really loved Ben, but apparently she also loved getting fucked behind his back occasionally.
