This happened when I was 15. I had been jerking off for about 7 years, but didn't ejaculate until I was almost 14. By he time I reached 15, I was so horny I jerked off every chance I got.
It was a languid hot summer Thursday afternoon, and I was home alone. My parents and sister had left to visit my grandparents, and would be gone for another 10 hours. I had already jerked off twice and was ready for my third. My 15 year old pecker was always raring to go, so just at the thought of my next go it began to harden. I had been naked since I began my first work out at 8 that morning. At the sight of my red hard penis, I lay down on my bed, spread my legs with the knees up and bent, and started jerking my swollen 7 incher. As I got deeper into the session, I closed my eyes and began fantasizing, the first vision was my hard prick getting slowly stroked. From that delight, I went on to imagine that I had the naked tits of my sister's friend Gail in my grasping hands. That inspiration brought me just up to the point of no return, so I stopped thinking I would rest for a minute or so and start again. When I opened my eyes, I was startled to see Gail sanding at the foot of the bed smiling knowingly at me. My pecker immediately lost its hardness; I stammered embarrassedly, and tried to hide my engorged penis from Gail.
Don't be embarrassed, she said; I do it every day.
How long have you been watching? I asked.
About 5 minutes, where's Sue?
She and my parents went to visit my grandparents.
While this talk was going on, Sue was removing her shirt and shorts and sat down on the bed next to me. I felt her hand wrap around my now shrunken pecker and begin stroking it firmly. Soon I was hard again and writhing in the third orgasm.
After I began to recover, I asked Gail how she learned to give such a good hand job.
I've had a lot of practice, she said, while slipping out of her bikinis and bra. You owe me a good orgasm; get to work.
As she said this, she rolled onto her back, spread her gorgeous legs, and I began stroking her clit lying on my side facing her. It only took about 2 minutes of this when she had her first come. I didn't stop with that, but kept stroking until she had another come. Then she reached for my hand after the last pussy eruption and said, That's enough for now.
We were laying next to each other resting on our backs when she said, I'll have to talk to Sue about her little brother's talents, we should put them to work.
Perhaps I'll continue this in a later post.
