For many years my normal way of masturbating was to hump my pillow or bed. One day when I was exploring in the attic above our garage, I found an old foam rubber pillow my mother had put up there along with a lot of other old bedding she no longer used. The pillow had a zipper, and for no reason I can think of I unzipped it, and noticed a hole in the foam rubber. Of course, with the pure logic of a young boy, I figured my penis would fit into that hole quite nicely, so I dropped my pants and mounted the pillow, slowly inserting my erection into the hole. I was probably 11 or 12, and to me this was sheer bliss. Pretty soon I was pounding away to a very strong, but dry, orgasm. When I was done, I zipped the pillow back up and hid it away, knowing I'd be back to visit that pillow in the near future.
The attic soon became one of my favorite hideaways for my furtive afternoon recreation. When I started ejaculating, I found that it felt neat when my penis rubbed around in my fresh semen inside the pillow. Of course, after a while the inside of the pillow became pretty crusty, so I made a new hole. I used that pillow for a bunch of years, making new holes whenever I needed to. I eventually ran out of places for new holes in that end of the pillow, so I pulled the pillow out of the zippered case and turned it around, and enjoyed it for a long time.
One day my mother had a cleaning up spree, and tossed out most of the junk in that attic, including my favorite pillow. I missed that pillow very badly; it was an old, dear friend that gave me a lot of pleasure.
