John and me have been best mates for over 20 years, ever since our first day at school. Over the years we often went out with the same girls, sometimes sharing them at the same times having the odd spitroast and DPing another. If one of us found a girl willing to be fucked by more than one bloke we'd always call the other. It was not a huge surprise then when he called me a couple of weeks ago to tell me he was meeting a woman who was seriously kinky and wanted lots of blokes to fuck her. John has a small business repairing cars and I work in an office in the nearby city. John had told me to come out to to his business premises, on Saturday at 10pm, in a quiet industrial estate, which was unusual for a shagging session and would tell me no more. I arrived and called his mobile to be let in, following him in to the workshop. There were already a couple of mates there, but more interestingly, blindfolded and tied to a workbench was a naked woman. Her head hanging off the edge she was being face fucked, taking the whole length of his cock as she took his prick down her throat, not even gagging. She looked to be in her thirties, small tits, pierced nipples, shaved cunt, clit hood pierced and two rows of thick heavy rings piercing her cunt flaps. "Who the fuck is she?" I asked. "You should know" he quietly replied, "She works in the same place as you". I didn't recognise the body but her red hair had looked familiar as I realised it was one of the Directors secretaries. A right snooty, stand offish bitch who looked down on most of us and, I seemed to recall recently divorced. Fucking great, a chance to fuck the bitch. She's said we can do what we want, bondage, caning, anything as long as we fuck her he told me. At that moment he went and let in six more mates who'd arrived just as she took a load of cum in her mouth and down her throat. Making sure she was securely blindfold I helped untie her, turning her over, retieing her over the bench, spreading and tieing her legs so she was helpless, ready to be fucked from behind. The others were already undressing so I stripped off watching as she was mounted from behind whilst having another cock stuffed in her mouth. Taking me to one side John told me that she had asked to be caned as she was fucked, suggesting I might like to do the honours he handed me a thin swishy cane, taking another himself. Watched by the lads, being fucked and sucking cock John and me stood either side. She was close to cumming as I swung the cane hitting her across the back, leaving a red mark, she flinched as the second cane stung her back. The bloke being sucked, came spraying his spunk in her hair as she demanded to be caned again, getting more aroused and cumming as we swished the canes on her body. The lad stuffing her cunt shot a load inside her moving back, giving us room to cane her buttocks. She writhed as she felt each stroke land, her back and arse covered in weals as she shuddered to another orgasm. We quickly untied her and she was led to the wall and just her arms tied to a hook. She was lifted on to another cock, wrapping her legs round his waist as she was fucked against the wall, while a couple sucked and bit her tits covering them in teeth marks, pulling her nipple rings hard, lifting her tits, extending her erect nipples. 3 or 4 fucked her like that all spunking inside her. She must have had an incredibly sensitive clitoris because she came almost as soon as she felt another cock penetrating her gaping hole. Tied to the wall, spunk running from her used cunt, soaking her thighs, dripping on the floor, not having a clue who'd fucked she looked a right slut. I caned her tits a couple of times then between her legs flicking it against her cunt, rattling the cunt rings. She'd been fucked about 6 times and wanted to be untied, before doing so a couple of the lads scooped the spunk and juices onto their fingers and fed it to her, pushing their fingers in her mouth for her to swallow then released her. She was led to me and John, pushed down to her knees and told to beg to be fucked again. My prick was stiff, listening to her begging for cock then John grabbed her hair pulling her face to his cock pushing it in to her mouth as I lifted her so she was bent from the waist, her legs spread. Standing behind I could see her swollen, gaping cunt, wet and waiting, spunk and sex juices still running out. Taking a buttock in each hand I spread them revealing her tight little arsehole. I'm not usually into arse fucking but for her I thought I'd make an exception. I slipped my cock into her cunt getting it well lubricated then a couple of fingers, followed by two more then my fist, giving her a hard fast fisting before pulling out and pushing a finger in her arse, quickly followed by a second. Her back arched and tensed, guessing what was coming next. John held her head still, face fucking her as I held her shitter open getting the end of my prick in her arse. Spitting on her to add some more lube then as I withdrew my fingers shoved my cock up her arse to replace them. I heard her groan from deep in her throat as she felt my cock penetrating her arse, sliding deeper and deeper in to her shit hole until my pubes were against her bum and I started to arse fuck her. As I pulled out I could see flecks of shit on my prick but just fucked her harder and faster, ramming my cock fully up her arse. John shot his load in her mouth and I could feel my spunk rising, holding her still shooting deep inside her bum. Before she could straighten, I pulled out, turned her round and pushed my shitty prick in her mouth. She took it, licking and sucking her shit off my cock until it was clean. I later fucked her, using the rings to stretched her cunt flaps and open her hole wide, watching as a she was later DP'd and arsefucked again. Before we finished she was led down into the inspection pit and told to lay down in the bottom. Standing around the pit we all got hold of our cocks aimed and pissed on her, soaking her hair, body, piss splashing her cunt then as she opened her mouth aiming a stream of piss down her throat. She was told to stay there as we dressed and all left except for John. As we left I couldn't resist calling out "Thanks Mrs ********, great fuck you kinky bitch, see you Monday". John told me the next day she'd asked who I was but he hadn't told her, but he'd was assured I wouldn't tell anyone. She has even agreed to do it again sometime as she enjoyed it so much. I saw her the next week, her usual bitchy self, although I thought she was sitting a little gingerly, the after effects of having her arse caned and fucked. It's tempting to drop a few hints but I probably won't as she has the Directors ear and could get me sacked and they wouldn't believe that she is such a kinky slut if I told them.
