I was a shy, geeky teenager. I was a really good swimmer and competed on my junior high and high school all-boys swim team. Being in all-boys schools and being a programming geek, I just really didn’t pay attention to girls much, or even have much of an opportunity to meet them. That changed the summer I graduated from high school and turned eighteen.
Up until then, my parents drove me everywhere. To practice, swim meets, etc. I was always too busy swimming or programming for hire to be bothered with learning to drive. Since I made good money programming, money wasn’t the issue of getting a car. Plus both of my parents had great jobs, my Dad ran his own insurance agency and my Mom was the head nurse at a hospital. It was just… well, I didn’t really see the point. I loved swimming and the solitary pursuit which was a lot like programming. Set a goal, achieve it, go to the next level.
My parents had enough and told me to get out of the house for the summer and stop working as a programmer. Get a driver's license and buy a car. Go do some living, with real people.
So I got a summer job as a lifeguard. I was the youngest one on the staff. While I may have been the youngest staff member, I was far and away the best swimmer as I had been competing on teams and at school since I was eight years old. I was very tall for my age at 6’4”, muscular but pretty thin. The fact that my penis was about eight inches long while flaccid, and as everyone wore the same kind of speedo shorts, well, my big dick on my thin muscular body, well, I kind of stuck out. Then my penis started getting hard at even the merest look at a young girl or woman emerging from the pool wet and dripping. Thankfully, when I was on the guard stand I was required to wear a lifebuoy and I could use it to shield somewhat and keep me from showing too badly. But every break, I’d have to jet into the restroom and pound my dick into cumming so I could go back outside and work the next shift. I was doing that three to four times a day at least. My dick was raw and sore all the time.
My mother had to drive me to work each day as I was still looking for a used car to buy. It was no biggie as she always left for work around 10 AM, so it worked out perfectly. Then my Dad would come pick me up at 4 or 5 PM depending on when he was done at work.
It had been raining for a day or so, so when that happened I did’t have to work. I slept late and headed into my parent’s bathroom through the hallway to take a shower as it was nicer and bigger than mine and my mother would already have left for work. One of my friends had texted me a link to a porno vid so I was leisurely watching that, getting harder by the minute and started to jack off. I put some lotion on my sore dick just to help it along. Just as I was getting ready to cum, the door to my parent's bedroom swung open, and there was my mother with just panties on. I proceeded to cum on her face, a couple of times on her breasts, her stomach and missed her a couple of times as well. I don’t think I had ever cum so much ever.
