I made a deal with my dormmate to let them listen in while I was fucking my gf

Not really a deal. My gf and I were students at the same uni, and she would come over to my dorm to stay the night from time to time. In my area, uni dorms usually don't have private rooms, I shared a space with three male mates, sleeping in three separate beds.

At the time, my girl and I had just started going out, and we'd only had sex once or twice. She was still very inexperienced and shy. One day, she texted me saying she was coming over to stay that night. When my two mates found out my gf was coming, they told me I should have sex with her tonight. They had said more than once that my gf was really cute (because she was shy sometimes) and had a great body. I was a bit resistant when I first heard it, but I slowly started to think it might actually work and might be hot

That night, my girl came over to my dorm as usual. When she came in, my two dormmates were already pretending to be asleep, and the lights were dim. I told her they were already asleep, and after chatting for a bit, I pulled her onto the bed and I told my girlfriend I really wanted to have sex, right here, right now. She was very hesitant because the other two dudes were in the same room, but I was already taking her clothes off (we were both under the covers at this point, so we were hidden), and then I slowly started caressing her. She resisted a little at first but then let me carry on, except she kept covering her own mouth, terrified she would make a sound. We really did fuck that night, trying a few different positions, all under the covers. I tried to keep my movements as quiet and slow as possible. When we finished, we quietly got dressed again.

The next evening, those two boys told me they had been silently listening to us and jerking in their own beds. One of them said he saw our duvet moving constantly and even caught a few glimpses of my girlfriend's tits. It was so hot to me, so, before we graduated, we did the same thing a few more times.
