My big O

This was it. My Mistress was at least appeased with my performance and she gave me permission to make myself CUM! At last! But... There was a catch - she forbade me to use my hands, toys or any objects. I could get off only by humping my pussy over furniture, scrubbing against walls and such. Easy deal, I thought. Although I had to get rid of my roomie, who fortunately had her lectures starting early in the morning. I couldn't sleep, tumbling imaptiently in my bed, waiting for the morning and her to leave. I only napped lightly for few times, waking up at slightest sound and checking my phone, if it is morning yet. Then - at last, A. woke up and rushed to bathroom, mumbling something about being late. I murmured from under my pillow I'm sick and I stay home today, and waited impatiently for her to finally leave. When I heard the doors slam, I sprung up from the bed and locked the doors. In a split second I was naked and I quickly throwed a towel over the headrest of my bed. It is simple, metal bar, only slightly lower than my crotch. I straddled it and I began to frantically ride it back and forth. It took me surprisingly long to get off, mostly because of bloody towel, sliding with me. I quickly threw it off and touched the metal bar with my bare slit. It felt cold and hard, but the touch drove me crazy. It took few more minutes, and suddenly, nearly in the instant the world exploded. It happened so fast, I had no time to stuff anything into my mouth. Everything suddenly turned blinding white and violent waves shook my body. I don't know how long it took. When I regained my consciousness I was still screaming, my hands clenched tightly on the metal bar before me. With great effort I let it go and clasped my mouth, turning my scream into muffled groaning. I rode the bar for at least four or five orgasms in a row, before finally collapsing on the floor. I curled and hold the thrown towel tightly against my leaking pussy, trembling and breathing heavily, sweet weariness coming over me. I passed away.

When the torture becomes the source of extasy...

When I woke up it was an hour later. I could only hope none of my neighbours were there to hear me cumming... I managed to reach for my notebook to mail my Mistress about my success, then I slowly gathered up. I could barely stand on my legs and I slowly shuffled towards bathroom.

Thank You, my Mistress for being so generous!
