this is true
When I was 18, I had never been caught masturbating before, nor did I have to worry about there being bad repercussions if I did. For the most part it was just me my mom and sisters who were at home, my dad worked out of town a lot. So my mom ad I had discussed masturbation, she was cool just that I would do it in private and she would respect my privacy, and if the door was closed then she or my sister would always knock.
So it went on like this for years I would go to my room close the door and jerk off. My main way of doing it was that I would hump my bed before I would go to sleep, but one day was really horny and I had read on a web site this interesting method to masturbate, and I decided to try it out.
I found the stuff I would need, a plastic sandwich bag, a long tube sock, and some lube (petroleum jelly). The idea was you took the lube put it in the bag and put over your cock. Then you put the sock over it, and put your dick between your mattress and box springs and hump. Your weight on top of the mattress would feel like you were fucking.
I was also into wearing pantyhose while masturbating at the time and I had a pair that I had torn a hole in so my cock could stick out the front that, I decided to put on for this as well. I had everything ready, so I put porn in the VCR and dick under the mattress, and started humping. It felt good, and I started to get into it. I was fucking my bed hard, grunting and moaning with pleasure, when my Mom busted into the room.
'Are you all....' She trailed off. I looked back at her, bent over my bed still humping, as the look on her face went from worry, to confusion, to rage.
'Pervert!!' She yelled as she shoved my face into the bed, and started to spank me hard on my ass. It was more than I could take, I came long and hard. My mother must have known what had happened because she stopped and let me go. I slumped down to the floor tears streaming down my face, my body shaking form the orgasm. My mother left me there. Later she said she was sorry, about her reaction that she did not know what came over her.
I have never stopped thinking about that day when I fucked my bed.
