I learned about my flatmate’s cuck fetish after fucking his girlfriend many times

My old flatmate and me met through a social media flatmate searching group. We were both newly graduates with shitty paying jobs so we became flatmates before we properly got to know each other.

Back then I used to spend weekends at home gaming because I didn’t want to spend the little money I had going out, and he usually spent them going out with his girlfriend. Every now and then she would come and stay over at ours especially if they got drunk.

One of these nights she came into my room on her tippy-toes as I was watching series on my phone in my bed, whispered me that my flatmate’s asleep she can’t get no sleep and asked me if she could join me. I nodded and said “sure let me turn the pc on” but she insisted snuggling in my bed and keep watching on my phone.

As we were watching the show I felt her feeling my arm with her hand and putting her leg on top of mine. Then she started running her fingers around the waistband of my shorts, and I started feeling her legs. As we went on I snuck my hand inside the basketball shorts that she borrowed from my flatmate and started sloppily kissing her. The night went on with a cautious sneaky fuck in my bed with her trying hard to hold her moans and me trying hard not to groan.

This turned out to be a usual thing we did, fucking behind the doors as my flatmate was sleeping, at least that’s what I thought so. One of these nights I realized every time we had sex she had her phone facing downwards. As we were cuddled up, recharging for a second round, I picked her phone up saying “what time is it” and saw that her phone was on an active call. I asked her who is it, she panicked and then grabbed the phone from my hand only for me to see it was my flatmate.

After a confused, weird and stressful conversation with her and my flatmate I learned that he’s been awake, listening to us fuck as well as recording the sound through the calls. This relationship lasted until I changed locations for work.
