Watching a Young Woman in The Supermarket

A few weeks ago I went shopping in the local supermarket. It was a hot day, so I was wearing shorts, with rather tight-fitting thin briefs underneath. For some reason I was feeling rather horny, and decided to visit the store's toilet first, to off-load some tension. I took down my shorts and pants and started gently massaging my cock. It felt pleasantly fruity and full, but on bringing myself to the brink I suddenly decided to wait until I got home for an even more satisfying eruption. So I returned to the shopping aisles and began putting items in my trolley. A few minutes later I caught sight of a delectable young woman who looked about 18, pushing a trolley. She had a lovely face, rather refined features, and a slim body. She was wearing a short skirt and one of those tops that looks like the upper part of a swimsuit. What really caught my attention was her breasts, which were very well-developed and, best of all, were partly visible above the thin material of her top. I could see the soft round flesh thrusting out of her chest, and a significant cleavage. It immediately made me want to see her naked breasts and to find out what it felt like to touch them. No chance of that, of course, but my penis was already responding and growing back to the size it had been a few minutes earlier in the toilet. I felt it pushing forward my underpants, its head straining against the thin material, and glancing down I saw my shorts bulging out in front of me. Fortunately the trolley helped me hide my condition from view, as I kept my eye on the young woman. After a while she moved out of sight, but I was determined to see her front view again, so moved round into the next aisle in order to face her. By now I felt I just had to do something about my engorged penis, which was aching to discharge semen, and I just could not resist putting my hand in my pocket and stimulating it. I soon began to experience that irresistable warm, expectant feeling that one gets in this way, and knew an orgasm was approaching. I managed to position myself close to the woman, while pretending to look for more items on the shelves but in reality gazing at her lovely firm breasts. Then quite suddenly I felt the familiar surging of fluids down below as my impending orgasm built, and knew what would happen in a few moments. I completely lost control in my need to ejaculate while staring at her chest, and sure enough, with my penis straining hard against my cotton briefs, its head greatly stimulated by the pressure, I felt a tremendously powerful jet of spunk force its way out, with an absolutely ecstatic throbbing, through my engorged, stiff fleshy tube. I let out an involuntary cry, something between a gasp and a grunt, which caused the pretty young woman to look round suddenly at me. As our eyes met, and of course unknown to her (I supposed), I felt another violent pulsation as a second wad of semen joined the first, doubling the sticky mess in my pants. The sensation of all this stuff trying to escape from my cock against the barrier of my underwear was incredibly intense, and even as she looked at me, another four jets shot out of me, leaving me feeling limp and wobbly as I gripped the handle of my trolley. I saw the girl look down, and realised that from where she stood the front of my shorts was in view. It was then that she smiled, thrusting her elbows back as girls often do to emphasize the shape of their tits, and I am sure she had caught sight of the grey stain which was already spreading in view of anyone who looked. The sad thing about a happening of this sort is that it leads nowhere, but the experience was really memorable. Perhaps a little less pleasant was the feeling of a massive quantity of sticky sperm in my pants, getting colder as I drove home. The next day it had all become caked in a thick yellow layer, and I kept those pants in that condition for several weeks as a reminder of that day.
