It was turning from a bad day to a very bad day at the office, too many problems to list, most of them caused by irritable men. My period was due and I could feel the tension building, that feeling of needing a release, a relief and an urge for calm was wanted. I had spoken to my FB earlier and he was being high maintenance, demanding too much of me. After much mulling over I decided to meet him, if nothing else it got me out and distracted from my day. I arrived at his flat, at least it was tidy, he'd made an acceptable effort. As I finished my wine I looked in his eyes and got a look from him I'd never seen before, animal like, instinctive. I stood up infront of him and as I did he tried to drag me back down onto the sofa, he triggered something within me, an instant aggression. As he tried to pull me onto his lap I grabbed his hair, his head swung back and I felt a rush of power. It was amazing, the blood pumped through my veins. I stood and lifted him from his seat pushing him back towards the wall, pinned against the wall, feeling his cock as I kissed him, the power was intense. Suddenly he pushed me back, grabbed my hair and dragged me into the bedroom. I wasn't expecting a return and the pain from my hair ran down my back. He flung me on the bed and straddled over me with his knees on my arms, I tried to shift him forward but his arms fell to the wall stopping my motion. My breath was short and shallow, my eyes fixed on his as he moved his hands around my neck, clenching tightly then letting go, I got the relief but not the sort I intended. I was pinned to the bed, helpless and losing the feeling in my arms, my legs of no use and yet aroused and getting moist, my heart began racing. The power exchanges where amazing, I'd never experienced anything like it, electric. He brought out the cuffs and chained my arms to the head of the bed. The leg spreader followed making me useless from head to toe. After a long and agonising session of him licking my pussy, inserting his fingers and teasing, he eventually grabbed his throbbing cock and thrust it within my pussy lips making me groan with much anticipated pleasure. He kept thrusting in me to the brink of orgasm then slowing down. Suddenly he moved away, unleashing my legs, then my arms, I pounced up and swung him around so he was laying down, the power was now mine. The roles reversed, he was strapped and helpless, he was mine. I began by biting his ear, kissing his neck and stroking his cock. I moved south licking his nipples and rubbing and rocking my clit against his leg, letting him feel how wet i was. His breathing became deep and slow, he was in another place. I knelt up and straddled across him facing the opposite direction, I began to ride his hot hard cock lettintg him watch my arse as i pumped up and down moaning in pleasure. He was close to orgasm, I could feel his cock tensing and his legs twitching. I jumped off and stroked him fast and furious, I needed to see him explode. It happened, he was full and it flew everywhere, his stomache was covered. I rubbed my fingers through it, massaging it into his skin and over my breasts, it was warm and silky, like velvet. Once we had calmed I felt instant relief, the anger had subsided, my needs had been met and it was time to go.
