Years ago I was single and the air conditioning is my house was on the fritz and my landlord was on vacation so it was going to be a week before my ac was going to get fixed. It was a very hot summer and I had to have my windows and doors open and fans going. I was really horny and I got naked and laid down on my couch and I was stroking my hard dick and fondling my big balls. I was stroking myself for about ten to fifteen minutes and I was oblivious to everything, when I was startled by a voice at my front door. My neighbor who was 19 living on her own for a couple of months now, she was standing there at my front door. She said can I come in to watch you pleasuring yourself. I had been attracted to her and I thought that she was pretty hot looking and very sexy, always wearing those tight fitting shorts and those loose fitting tank tops without a bra. She said that she she has seen me jerking off several times. She said that she loved to watch guys jerking off. I was stunned and kind of embarrassed and I hadn't said anything. She walked in and she sat down on the coffee table and she said don't be shy, and just laying there gripping your hard cock, stroke it for me. I began slowly stroking my dick and fondling my balls while she sat there watching me. After a few minutes I was stroking my dick faster and I was feeling more relaxed jerking off in front of her. I was actually enjoying jerking off while she watched. I was staring at her sexy tits, and she realized it so she asked me if I liked her tits. I told her that I did. She pulled her tank top off and said is that better. I told her that it was, she then told me that now I had her sexy tits to stare at for motivation to jerk off. She told me that when I was ready to cum that I could cum onto her 34C tits. She had light brown nipples that were very hard. As I was stroking myself she asked me on average how long do I stroke it before cumming. I told her that it varied anywhere from five minutes to as long as an hour. She said really, nice. About twenty minutes or so later I was stroking my dick very fast and my balls were bouncing around and she seemed more anxious. She said to let her know when I was about to cum. Several minutes later I was furiously stroking my dick and I began breathing heavier and then I told her that I was about to cum. She then leaned forward and she rubbed her sexy tits against my dick and several strokes later and I was cumming all over those sexy tits of hers. I had completely covered her tits with my cum. She then repositioned herself and she took the head of my dick into her mouth and she licked and sucked on it for a minute. She then told me that I could take a picture of her cum covered tits so that I could have something to jerk off too. I took a couple of pictures of her topless cum covered tits. She then said that she would like to come by sometimes to watch me jerking off. That summer she was at my place almost every night watching me jerking off. The night before she moved out to go back to college she came over and we fucked all night.
