Part 1
This is the beginning of story. A story of a boy discovering himself. In doing so, I had the help of my 7 year older brother-in-law. I got to do lots of things with him and learned from him.
My sister was 6 years older than me and she had the same boyfriend since she was 15. I considered him my brother. I had known him since I was little, and he spent more time at our house than he did at his own. In summers, when the temperature was very hot, we used to swim in the lake at the back of our house. Afterwards, my sister, my brother-in-law, my younger brother and I would take a shower together in our swimwear. The four of us shared one showerhead. We took turns. My brother-in-law and sister would help me and my brother with washing our hair and toweling us off. Of course, I was already able to do it myself, but I enjoyed it when it was done for me. In my puberty things changed. I grew taller and got more hair everywhere. I also lost the grip on my body. Just looking at my own penis was more than enough to get hard and remain hard for a long time. I began to enjoy touching it. But I was also embarrassed by it. I didn't like the shower parties any longer and tried to stay out of the way as much as possible. The very thought of the four of us in the shower, which used to be so natural and seemed so innocent, had all of a sudden turned into a huge thing. Just taking off my clothes in front of other people would have been enough to get hard. It was also around that time I started to notice how my brother-in-law looked. He was in his early twenties and had a lean but muscular body. Bronzed from the sun and a touch of chest hair. I also noticed only now that when he got out of the water his bulge was way bigger than mine. Or that of my father, who I had of course also seen in his swimming trunks. My brother-in-law never wore any swimwear, but just went in the water in his underwear. When he got out of the water, the wet fabric stuck even more tightly against his body. You could clearly see his penis. It stuck out quite clearly and I was amazed at the size of it. Even out of the cold water his dick was still huge. When I got into the cold water my penis would shrivel up to a barnacle that had just surfaced above the sea. But not his. With each step he took it shifted as if it was a creature of its own. As if he' d dug up something big and alive from the bottom of the lake and put it in his shorts. I was trying really hard to watch him from all angles as discreetly as possible. Even got me a pair of goggles for my 16th birthday so that I would be able to see the beauty of nature that he had between his legs from under the water as well. But it was far too muddy and that experiment failed miserably. But during that summer and the ones that followed, I kept watching him from a distance. Without him knowing it, he helped me with my fantasies in my awakening puberty. But showering together, I no longer had the nerve to do so. As I got older, the craving to take a shower with him grew though.
It never came to the point of showering together. But at night in bed, as I closed my eyes and wrapped my hand around my cock, I would shower with him ever more extensively and for longer periods of time. It was during such a kind of fantasy, that I experienced ecstasy for the very first time. Stroking over the head of my cock had become harder and faster. I could feel my tight foreskin sliding back and forth over my swollen dickhead. A sensation came over me that was indescribable and eventually ended on my stomach in a white sticky pool of wetness. It was then that my body said, " Now you are a man. From now on you can reproduce and all of your fantasies will end up in a puddle of white sperm on your belly." From there on, I also felt like I wasn't a kid anymore. I no longer wanted to play outside, but instead wanted to play with myself. Every moment of each day when I was by myself for a moment I would bring myself to ecstasy. While my body evolved and I became more skilled in playing with myself, the small puddle of thick, snow-white semen developed into larger and thinner jets of cum that frequently sprayed over the top of my head against all sorts of surfaces. I also became increasingly more curious and daring. I stopped taking showers with them, but I tried to watch through the slit of the door whenever my sister and my brother-in-law showered after a swim. Or just occasionally walked into their bedrooms as they changed clothes, in the hopes of glimpsing his bare body. If that worked even a tiny bit, it fueled my fantasy.
