What a summer this has been so far!!
First, a little about me: I'm 18 but have always looked much younger. I'm 5'10' and weigh just under 150 pounds. I must be a late developer, because I still look like a 12 year old. My blond hair is long and I have no other body hair except for a small patch of pubes above my genitals, but it's very soft and hard to see.
In spite of my looks and size, my genitals are fully developed and look huge. Showers at school were always a problem because the other boys couldn't take their eyes off my equipment, and would make comments about the size of my balls and penis. My penis, when soft, is quite large and hangs down way below my ball sac. When hard, it stretches to 7.5 inches, and stands straight up against my belly. No one in the showers ever saw me hard, but I was asked a few times to get a boner, so they could 'see'. I prefer jerking off alone, lubed with the large amounts of pre-cum I produce, and usually shoot quite a load when I come.
I always had a lot of male friends, and occasionally jerk off with some of them when the need arises. During these sessions my partners are always amazed at how my cock looks in proportion to the rest of my body, and usually shoot their loads very quickly.
My friend Sean has to be the fastest shooter I've ever seen. Yesterday he came over while my parents were out, and soon the talk turned to sex and masturbation. He loves to see my cock and didn't waste any time pulling down my shorts to expose my rapidly growing monster.
Sean now had a big bulge in his white gym shorts, and a wet spot was clearly visible. My throbbing member was soon at attention against my stomach, and he started rubbing it with the palm of his hand. The feeling was terrific, and it wasn't long before pre-cum was flowing, causing his palm to slip and slide over my incredible boner. I was moaning with pleasure, and all of sudden Sean's mouth opened and he let out a gasp, as a load of cum shot through the fabric of his shorts onto his arm as he rubbed me up and down. Two more jets shot out before the pulsations in his shorts stopped.
This was incredibly erotic, and I let out a yell as my load began spewing out, hitting me under the chin and coating my left ear. My stomach cavity took the rest, causing a large pool of cum to settle into my belly button. I looked at Sean's shorts and saw they were completely soaked with the outline of his softening cock clearly visible.
We cleaned up in the shower, and I gave Sean a pair of my shorts to wear home. I couldn't wait for the next visit!!
