As a teenager I lived with my large family in a contemporary home with many decks all around the house. Whenever I was home alone, I would strip naked and parade my near-permanent erection around the house and onto the decks. We lived in the woods, and the house was about fifty yards off of the street. I convinced myself that I would not be seen, and I would lean against the railing, by body arched from my tip-toes, and fuck my fist until I ejaculated into the woods. I must have done this a thousand times over the course of several years. One day I met a girl who lived a few streets over from my house and when she found out where I lived, she immediately said 'oh, the naked people house!' I claimed that the naked people must be some of my many siblings, and carried on masturbating in view of cars passing by. I realized that I must have been seen by all of my neighbors, but no one ever said anything.
The bottom floor of our home had a 'playroom' across one end and a central hallway that led to the other end of the house with three bedrooms, a bathroom and a laundry room off of it, and a stair immediately off the playroom. I and my five brothers shared the three bedrooms, my two sisters lived upstairs. We all used a mirror that was across the hallway from the laundry room. From the time I started masturbating to ejaculation, around thirteen, I would stand in the hallway, usually naked, and look at myself in the mirror while I masturbated. Sometimes I would come on the mirror, ejaculating all over it, as I came with tremendous force. (I could lay in bed and, arching my body in orgasm, I could hit the ceiling with my ejaculation, or, if I leaned to my right, I could hit the opposite wall.) To not hit the hallway mirror, I would back into the laundry room as far as I could, a good nine or ten feet, and lay down a trail of semen from me to the wall below the mirror.
I would frequently stand in front of the mirror and edge, when I knew that there were people in the playroom, or the other bedrooms. If someone walked into the hallway, I would scoot into my room on tiptoe, and many times I would be ejaculating into my cupped left hand while stroking in a frenzy. Sometimes, if I was too far gone, I would just stand there, arching from my toes, my whole body vibrating, and ejaculate onto the mirror and wall.
