I recently found this site, and am enjoying it very much. It goes without saying that it arouses me to the point of masturbation, but it also brings back fond memories of long ago.
My first introduction to masturbation was when I was about 12, by a male cousin who was a year older than I. I had gone to spend a week with him (and his parents). The first night I was there, I found out we would sleep together, in the same bed.
As we lay there, he asked me if I ever played with myself. I hadn't, and told him so. He then told me he often played with himself and proceeded to show me. I saw his penis grow and at the same time, felt something similar happen to me. I was in awe as I watched him jacking himself. He then reached over and started jacking me. It was a feeling I had never experienced, and I didn't want it to end.
He took my hand and placed it on his penis and told me to do to him what he was doing to me. As we lay there, he told me to do it slowly so it would last, as he was doing to me. He proceeded to tell me how he masturbated quite often, and what the feelings were that he experienced. Also telling me what I would feel. He explained how to do it, and told me what would eventually happen, the orgasm. He kept jacking me until I felt the most wonderful feeling I ever experienced course through my body. It was a 'dry' orgasm, but as he explained, when I got older 'stuff' would come out. He then proceeded to show me, by masturbating himself until he ejaculated. I was amazed to see the white liquid spurt from his penis. I had never seen anything like this before.
Suffice to say, we spent every night of that week doing the same things to ourselves and to each other. This was my introduction to self-pleasure, and I loved it. It was a great vacation and we did this for a couple more years, until we got older and I no longer vacationed with them.
