As Leanne and I sat in the back of Don's car, naked but for our loosely tied raincoats, me still with a huge butt plug wedged up my arse, I asked Don what the gang bang party would be like. "Tell the slut Leanne" he ordered. So Leanne began to tell me that there would just be a handful of women and thirty or forty guys, mostly a fair bit younger than us and horny as hell. "So be prepared to be fucked senseless Deb, they'll love you because you're new meat." She then told me something that shocked me, we would both be paid £500 to have sex with all these men! "But i'm not a prostitute " I gasped. "You are now " growled Don "get the butt plug out of the bitch's arse Leanne, she should be nicely stretched by now" Leanne reached under my mac and with one quick twist of the plugs handle pulled the butt plug and it came out with a loud plop. Soon we were driving up the driveway of a huge mansion Don parked the car and told us both to take our coats off. We sashayed naked up the steps dressed only in high heels, clamps and piercings. After ringing the bell we were taken into the house by a butler after Don told him he had brought some of the entertainment. We were taken into a huge ball room in which six naked sluts , one of whom was a regional television weather girl and another the wife of a famous footballer were being spit roast while a crowd of other men, many with their cocks out waited for their turn. Soon Leanne and I were being groped by eager hands and I was having the pleasure of my first double penetration as two well endowed heavily tattooed young studs began to pound my juicy cunt and well stretched arsehole. By the end of the evening nearly every one of the studs present had fucked me , most of them in every hole, I had what felt like gallons of spunk leaking out of every orifice and as well as my first dp I had been triple penetrated and took my first ever double anal pounding. Don had seemed to spend most of the evening fucking the weather girl and the footballer's wife in turn while Leanne like me attempted to fuck every man in the room. After several hours of non stop sex Leanne came over to me and while we gently began to lick the spunk out of each others cunts and arseholes most of the guys began to piss on the weather girl until I thought she was going to drown with the constant torrent . As Don walked our tired aching, naked bodies to the car the butler handed us each an envelope which he said contained our "fees". I was told that I was being paid £250 bonus as I had been such an enthusiastic first time gang bang participant. The butler said that the owner of the house had asked whether I would be back next month. I answered no that I was quite respectable and it had been a one off, never to be repeated performance. Don immediately dropped his trousers, offered me his cock which I sucked on hungrily and told the butler that I was a cock hungry bitch and would certainly be back. The next day my ex brought the children back from their holiday, while in the evening my boyfriend Dave also returned, came round and dropped a bombshell by dropping to his knees and proposing telling me how much he'd missed me in the last week and how it proved to him that he couldn't live without me.To my astonishment considering the events of the past few days I found myself accepting Dave's proposal. He then looked puzzled at the mahogony spray tan and asked why i'd had it done, thinking quickly I relied that I didn't want him coming back from his holidays and finding a pale girlfriend so i'd done it for him. I now had to thinking of a way of convincing Don that my days as his sex slave were over.
