Yes, yes YES to all of the above! Once I started to ejaculate around age eleven (just a small pearly dribble then, but by twelve or thirteen getting to be a few good spurts, and by fifteen a series of sticky white jets flying around everywhere), I became obsessed with ‘marking’ my masturbation sessions with liquid evidence of my orgasm. When puberty hit I was jacking off three to five times a day, frequently away from my bedroom, and so I would leave ‘deposits’ in various parts of the house where I had shot my load. Mostly they dried into nondescript spots or stains which were innocuous enough–unless you knew the secret. I would look at an old cum stain on the patio or the front porch and get a secret thrill to remember shooting my spunk onto that spot.
I had a standing mirror in my room which played a big part of my masturbation ritual. Not only did I love to watch myself jacking off in the mirror–putting on a show for myself–I often shot my jizz onto the glass. I don’t know what it is, but I have always had a fascination with seeing my cum on glass. Something about the sight of my pearlescent semen pooled on a pane of glass or flowing down a window or mirror, is hot to me. Sometimes I let the cum remain on the mirror, an overt trophy of my shameless masturbationism.
In my first apartment I had to myself, I had a glass-topped coffee table: guess what kept landing on it? I shot load after load onto that glass top, usually on my knees beside the table. Sometimes i would run the end of my cock through the fresh puddle of cum as I milked out the last drops of spunk. At one point the thing was totally covered in my dried semen.
Mostly these days i jack off and cum on myself. I like the feel of my hot cum drying on my skin. Sometimes I leave it there and go out into the world with an undergarment of dried cum. I see the people passing me on the street and think, “If you only knew: You are in the presence of a true Jack-Off Master.”
