Between A Rock And A Hard Place
Years ago I used to often go for a walk in a nearby park, taking paths not many other people took and exploring off paths as well.
Back then I was not in the greatest place mentally, just out of a bad relationship and feeling a lot of guilt and shame about where my life was going. In the intimate side of my life, this manifested as me having loads of deprived, kinky and degrading sex with different men, but also doing humiliating and degrading things to myself while I masturbated, as if to punish myself.
One day, off the path, I found a rock jutting out of the ground, kind of narrow and flat at the top. As I was walking, I was thinking about one depraved thing or another and by the time I saw the rock, I was already sufficiently wet. So I thought to myself, look how convenient this rock is, I bet it would be good for humping. I was in the middle of this secluded wooded area, nobody around, so I dropped my pants and underwear far enough so I could crouch above the rock and rub my clit against it until I came, ass out in the cold and everything. It took no time at all, the rock was cold and the way my clit rubbed against the edge of it felt just right. I was filled with adrenaline too, afraid somebody might hear me or see me. I think it was a minute, at most two of humping that rock before I orgasmed, quite hard. It felt so good physically, but emotionally I felt awful about it! I guess the action served the purpose of making me feel punished and humiliated. And I did this on multiple different walks after that first time, maybe five or six times in total.
Crazy thing is, if I was out and about with my Master, and he ordered me to do it or something similar, I'd probably love every second of it, despite the humiliation.
Since then I've stuck to humping objects at my home, when the mood strikes. My favourite is the dining table corner. And no more guilt!
