Masturbating Under My Coat

Last winter I was walking along a dimly lit street in the early evening wearing a fairly heavy overcoat which has pockets with slits allowing access to both trouser pockets. I realized that night that I could reach in and unzip as I walked along, and no-one would know. Then I could pull out my cock.

I did that for the first time last winter and it felt wonderful. I walked behind two young women who were engrossed in conversation. They both had coats on but they were short coats and their legs were exposed. They must have been wearing skirts, and quite short ones I guessed. Just that thought made me stiff and I began to rub myself gently.

To begin with I masturbated slowly but as I got wetter and stiffer I increased my speed. I tried to keep my right arm from moving too much so it wasn't obvious what I was doing. As we walked along, I got closer to them and the speed of my masturbating increased. I began to hear what they were saying, and it almost felt like I was part of their conversation. By the time I got close enough to go past them I was wanking fast, and my legs were weak with excitement. I wanted to cum so much and I was very close.

As I drew level, I stumbled slightly, and gently nudged one of them. She turned to say something but quickly I apologized, even though my voice came out slurred as if I was drunk. She half smiled at me in acceptance of my apology and as she did so I came. My cock was rigid and pointing straight up, under the undone buttons at the bottom of my shirt. I shot three big spurts straight up, spraying my stomach with hot streaks of cum. Oh God, it felt good.

I couldn't help groaning out loud as I shot my load, and even after the third big squirt I could feel two more smaller ones spurt on to my hand. I was covered in cum but still walking alongside the two women. The one nearest to me glanced again at me when she heard me groan and I don't know what she thought. But if she's ever heard a man making a noise when he cums, she will have known what just happened.

I masturbated again that night in bed, thinking of her looking at me and guessing what I was doing. It feels lovely thinking of her hearing me groan. Did she know I had cum? Maybe not for sure but hearing me and seeing the look on my face, she probably suspected.
