I saw her waving and sitting at the opposite tower but I did not expect her to get into the room. When she opened the door to get in, I was being fucked in front of the window and my face was towards the window. My back was towards the door.
After she got in, her boyfriend switched the position!! He turned my face towards the door so his girlfriend (my friend) could see me clearly. I was shocked and tried to use my hand to cover my boobs because although we were close friends but we never get naked in front of each other. However, I could not cover anything. I was fucked in doggie style and both hands were held tight by her boyfriend. So you could imagine, my boobs moved up and down as he banged my pussy at the same time my friend was watching and cheering her boyfriend. I was humiliated but after a while, I cared no more. She saw only my boobs. The worst (or may be the best) part was that her boyfriend suddenly laid down so I became on top riding his cock. He still banged me from down there holding both of my hands. My boobs waved up/down and my legs were spread wide in front my friend. I was sure that boyfriend intentionally did it so I was naked and spread wide for her to see and took pictures of my spread wet pussy too. It was so much humiliated and I wanted to stop there but, as you know, it would not happen. I was still fucked until her boyfriend unloaded.
