Stroking for an Audience...

I was in my twenties, prior to being married, and was a regular 'Jacker'. I had a small 1st floor apartment, and the bathroom window opened outward, and was partially hidden by a large Podocarpus Bush-like tree. Every night before going to bed, I would open the bathroom window, and brush my teeth in only my briefs, standing at the sink...as I brushed, I would get hard, (still in my briefs) with my good sized Dick growing to the side, anticipating my coming stroke. One night after brushing my teeth, I was standing at the sink, erection growing in my briefs, admiring my bod in the mirror when I heard a slight noise outside the open window. I thought was that the breeze? or was it someone outside watching me??? Anticipating it might be someone, I turned slightly to the side, which displayed my erect Cock toward the open window. Then, I heard another sound; a twig snapped, as if someone was getting closer, positioning themselves for the best view. My heart was racing, as I slowly began to stroke my hardon thru my briefs. I knew they were here for a show, and I was the dude to give them a good one! I continued to play with my erection thru my shorts slowly pulling them down showing some dark curly pubic hair; my Cock was starting to drool pre-cum, making a wet-spot where the head stretched the thin cotton material. I slowly rubbed the wet spot spreading the wetness around, slippery, sliding around and around the bulging head of my Throbber. I slowly removed my briefs, letting my hardon stand straight out, still rubbing pre around the head. I sat down on the toilet, leaned back, spread my legs and started to slowly stroke, while playing with my nipples with the free hand. Then I heard a new sound: It was a slight zipppppppppp-ing sound, as my audience opened up their trousers and started to rub themselves, as well. I was so horned at this point, I knew it wouldn't take long before I was cumming...I stroked it faster, sliding my hand over my seven inches of thobbing meat, and then I was there...cumming rope after rope of hot spurty cum onto my chest and stomach; that's when I heard a slight muffled moan from outside the window, knowing they had cum too. This went on for over 6 months that I was staying there, always the same scenario, me not knowing who it was, but they cumming with me nearly everytime I shot a load. Sometimes I would hear a car drive away, other times someone went into the front door of the House I was staying in. I suspect I was turning on more than one person, maybe they were together, I don't know, but it sure was fun for us all!
