Great Jack-off Day

I had no classes last Monday due to a school affair during the weekend. Since I was all alone in my house and I was really horny(I haven't jacked-off for more than a week then), I quickly removed my boxers and shirt and decided to give myself a good time. I then decided not to go through the usual routine(using my hands) and I searched around the house to find something as replacement. I then found a huge ziplock bag in the kitchen counter and I quickly brought it up into my room. I then filled it with some lubricant, placed it between two large pillows, and stuck my 8 1/2 hard dick into it. I then pumped in and out of it slowly, trying not to arouse myself too quickly. After about an hour of intense pumping and perspiring, I could not take the intensity anymore and so I decided to end it. As I was reaching my orgasm, I saw through my window a hot lady passing along the sidewalk. I then pumped hard and at that moment, I moaned with an intense orgasm. For about 10 seconds, I could hear my cum squirting from my dick into the bag and I continued to moan loudly under the intensity until it all ended. During that time, I think the lady heard my moans for I heard her footsteps stop for a while before continuing on. After some minutes of panting and with perspiration dripping from my chest and abs, I reached for the bag, which is half-filled of my white cum, and I quickly threw it into the garbage bin.

It was truly a great jack-off day and I wish I could repeat it again sometime!!
