The view of her breasts and the view of her nipples over her wet shirt made my man stand erect. I controlled myself somehow.“Aare how am I going to ...pply the spray on my back? Amit ektu help kore debe please?”“Yeah sure. Ok”I took the spray from her and thought how to tell her to lift up her shirt a bit so that I could put it on her back bone. She said how foolish of her and lifted up her shirt more than what I needed my eyes were stuck at her shapely waist. Sweat was trickling down her back. I. With her bend over, her ass was right in front of me and I couldn't resist the urge to keep spanking her ass, quietly of course, as I didn't want to wake anyone in the apartment. As we were facing a mirror, we kept making eye contact in the mirror, but all I could look at was her huge tits bouncing while she bounced on my dick! I could tell she liked it, as she was moaning but trying to keep quiet to not wake anyone. We kept fucking for another 10 minutes before I could take it no more. It was. I answered probably way faster than I should have. I was just so relaxed, so horny, and the idea of helping my brother in such a public place ... with my parents right there... I couldn’t resist.“Shhh,” was my only reply, and as the giant robots battled before me, I tried to be as subtle as I could, reaching over and unzipping my brother’s pants, guiding his erection out into the cinema where anyone could see.I was so turned on by the idea of what we were going to do - on one hand, I wanted to. Once done, she pulled my wrists behind my back and tied them between them. M then resumed the work of the nipples by pinching and twisting them after removing the clamps that she immediately put back in place. As I moaned, M ordered me to suppress him. Then M took a dog leash which she attached to the loop of the clip of my penis and pulled on it to get me up. The pain made that I could not suppress a cry but M tugged harder on the leash until I dragged me to the bedroom. The was waiting for me.
