I had been meeting James for several weeks, it was nothing rushed as we had agreed to to build up confidence and trust with each other. Over that time we had played quite a lot, me always the submissive slut waiting to do her masters bidding, James having taken full advantage of me using my mouth and hole to satisfy my needs. he was a creative master tying me and cuffing me when he wanted no response, training me with a riding crop when he did. I had learnt well I felt and my bum cheeks not getting so sore, though I was often naughty just to get a beating James saw through it and refused me. This changed however when he bought a friend with him one day, we had discussed him surprising me and and that is exactly what he did. Stuart was his name and I had never met him or talked to him prior to finding him stood over me. Stood over me because it was my usual place to be knelt blind folded on the kitchen floor, holding the handle of my leash aloft waiting for James to arrive. "Get up slut" were the first words he spoke to me, I was shocked to here a voice that was not James's as you can imagine, there having been no indication that it was anyone other than my usual guest that had entered the house. I got to to my feet if only to feel less vulnerable, though in my tight corset, and 4 inch heels it was not an easy manouver. As I got part way he yanked my leash, which he had taken off me as i had expected James to do, I lost my balance and fell back to the floor. he put his foot on my back. Pinned as I was I lay still, Panic started to fill me with dread, though I wondered if this guy was my surprise, otherwise how would he have known how to get in. He took his foot of my back, " I said get up slut" I tried again, this time I received a slap on the face, before i was yanked down again. "you forgot to thank me" I was told, " now try again, I said "thank you sir" I felt adding a sir would help, it did no harm at least as i was allowed to stand. "Stand still and do not move" he let go of the leash which dropped to my side. I stood very still though as I was not moving very fast in these heels on a tile floor, it was hard enough to move about when I could see. While I stood it was clear, the guy was at least removing his trousers, though i could not be sure what else. he reclaimed the leash from my side, then grabbed my wrist. he maneuvered my hand to his crotch were his semi erect cock resided. my hand instinctively fondled it and as scared as i was I was pleased it responded. it got harder, as I stroked and it felt large in my hand. " you like that " he asked. " yes sir " I replied. "you fucking slut" was his retort. removing my hand and dragging me across the room. I was forced over the work top, and heard the chain of my leash being wrapped round the taps, securing me in place. I had never felt so vulnerable, my short skirt not covering my ass, my so tight corset restricting my breathing. then the first blow of the crop hit home, I yelped with pain, several more followed, it stung like hell and i cried out. my blind fold had slipped but it hardly helped face down as I was over the sink. I felt my panties being yanked, then from the corner of my eye the scissors being taken from their holder, I held my breath, but herd 2 snips and no pain, my panties fell away. the scissors I saw were replaced, then my panties stuffed in my mouth. "you dirty Fucking Whore" and the beating started over. tears ran down my cheeks. oh my make up I thought, irrationally. Then it stopped.. Silence apart from heavy breathing, Then my hand was guided to that cock again, it was an awkward position to do anything from, but i tried my best. James had been training me to fondle or suck cocks if they were presented in the right place. Agian it grew hard, and again my hand was removed from it. Then movement and it was pushing against my hole. i was already lubed as James had requested this. so it slid easily into me. my assailant fucked me hard. his crotch banging against the swelling on my freshly beaten ass, adding to my pleasure if not his. He soon came, and once he had, simply dressed and left. While he dressed I just stayed still not wanting to antagonise him. I unwrapped my leash from the taps, stood and examined my ass. on the table was a note. "hello Lisa hoped you enjoyed Stuart, Love James X" This was a year or more ago, my surprise was more a shock, but I have now gotten used to the occasional stranger turning up instead of James. it is usually a treat.
