I live on a very busy corner in a small college town and my picture window looks out over one of the nicer intersections. During the Spring, Summer and early Fall months I am constantly treated to the sight of young flesh walking by in the skimpiest of costumes. Since my office is also in my living room I developed the habit of accessing a porn site and stroking my cock for an hour or so while hot young girls would stroll past at the same time. I always kept the blinds in a half-closed position for fear of getting caught, but this fear also helped produce some amazing orgasms
Two years ago, a salesman talked me into getting the window mirrored in order to cut down on utility bills. Shortly after, I found that no one could see in and I could stroke my cock with the blinds wide open. This nearly public display of masturbation produced erections that were hotter, harder, thicker and longer than any I ever experienced in my entire life. I would waste hours sitting at my desk with my hard cock in hand and waiting for any unsuspecting person to walk by.
On the third day after the window had been mirrored, I was sitting at the desk with my hand leisurely stoking up and down my throbbing cock, just bringing my self to the brink and then relaxing. Then this really hot co-ed in shorts and a spaghetti strap camisole top, stopped and looked back at the window. I stopped in mid-stroke for fear she has seen something, but then she walked right up to the window and bent over. She produced a container of lip-gloss and began to apply it while looking at her reflection.
I was at the window in a flash with my cock only an inch from her glistening lips. I was stroking like mad when she pursed her lips to check the application and I imagined my cock was just sliding past that moistness. At the same time, her position had dropped the front of her top and I could see the tiny nipples on her braless A cup tits, just swinging there freely. My cock seemed to grow another inch and I couldn't hold back any longer. Cum just started spraying out the end of my throbbing, flared head. I quickly turned sideways, so the spurts would not hit the glass and alarm her. I was still cumming, as she straightened up with one breast completely out of her top. She put it away and walked off.
I was still weak in the knees from the most terrific orgasm I have ever experienced, as I watched her tight ass stroll down the street. I have two other stories about the picture window and I will post them later.
