So very sexy, knowing what you are doing and feeling. If I was sitting next to you doing this I would have to get my cock out and slowly wank with you. When you have to cum, you just have to cum. This must be happening all the time, just not much of it filmed. Please keep on like this to keep us all entertained.
Some years ago, on a rather long, boring train journey, I was fortunate enough to encounter a middle aged lady doing very similar....she was sat across from me, and I was dozing, and my mind wandered to sexy thoughts.....my cock began to swell and stiffen, and had made an outline along the thigh of my jeans, and I noticed she was glancing over, with her legs crossed in her skirt and she was making subtle movements of her hips....she had a misty look in her eyes, and I deliberately tensed my cock, making it move, and I heard her very softly gasp and she stared directly at my outline and squeezed her thighs tighter.....I could see her nipples were very obviously erect under her thin white blouse and bra, and it was clear she was clenching! It was so sexy, I made no attempt to conceal my very obvious outline....!
