In our first summer together, my girlfriend [F]25 and I [M]21 stayed at my cousin’s house for vacations.
The three of us spent the day together, on beaches and drinking alcohol out there. When we got to the apartment we had dinner, he went to sleep in his room and we slept on a sofa-bed in the living room.
As we were a little drunk and horny we began to fuck, we covered our parts with a sheet a little and he began to ride me.
After a while I heard the door of my cousin’s room and noticed how he had gone out to smoke at the living room window, 2 meters from us. When he left his room I told my girlfriend to stop but she didn’t even though I repeated it several times, she kept riding me gently and moaning softly, I think he heard us and realized it.
It continued like this until my cousin returned to the room and then we came. The next day I ask her why she continued and she told me that he didn’t realize that my cousin was next to us.
It is the most exciting and embarrassing thing that has happened to us at the same time.
