My name is Sam, I'm 30 years old and a size 20. I've not had a boyfriend for a while, people tell me i'm pretty but I can't help but feel that my size puts some men off. Last night was the Christmas party of the office where I work as a sales manager. I found myself chatting to one of the IT guys, a silver fox in his fifties called Bob with more than a passing resemblance to George Clooney. As the wine flowed, Bob began to flirt with me telling me what a gorgeous woman I was and how he couldn't believe I didn't have a boyfriend. To cut a long story short I invited him back to the room I was staying in at a local hotel, Bob said that he'd love to but that he had a couple of errands to do and that he'd see me in my room in an hour. I thought he was letting me down gently and wouldn't turn up, but sure enough after an hour there was a knock on my door and when I opened it Bob was standing there with a wicked grin on his face telling me he'd brought me some presents. He opened his bag and to my astonishment produced a huge bottle of baby oil, some nipple clamps , a butt plug and a bottle of champagne. I asked him what sort of girl he thought I was , he replied an insatiable one, and within five minutes he had me naked, covered in baby oil with my nipples clamped and the butt plug wedged up my arse . He proceeded to fuck me for hours in every orifice, he later told me he'd taken a viagra tablet, before phoning one of the other girls from the office, a tall leggy brunette called Debs who is a few years older than me, when Debs arrived he took turns fucking both of us up the arse with his rampant cock. When Bob finally left me and Debs were both sore and covered in spunk. As we lay there naked, Debs told me that Bob had been fucking her for a couple of months now and that sometimes he took her to sex parties and occasionally they went dogging. Debs then told me that I could become a dirty bitch like her and started fisting my well fucked cunt, before squatting over my face and pissing in my mouth. Bob rang this morning and asked me if I fancied going dogging tonight , of course I said yes, i'll let you know what happens.
