When we returned from our holiday we agreed that everything should to return to normal as much as possible and for a few weeks everything was. Our sex life was as passionate as ever and we would fuck in risqué places as we always had but it was just us two and her trusted dildos. There were subtle changes in Lucy though. Her clothes became a little more revealing, work skirts a little shorter and tops slightly more sheer and she mostly stopped wearing knickers except when she wore her white trousers to work when she would wear the darkest or brightest coloured thong she had so you could make out the shape of it through her trousers. A few weeks back from our holiday we met up with Simon and Dan to go clubbing in Kings Cross. Lucy wore skin tight super low hipsters that exposed her pelvic bones and a tiny boob tube. She looked amazing and the guys were clearly impressed as they greeted us. The club was dark and sweaty and the music was getting everyone worked up. As the night progressed we all got pretty wasted and at the end as Simon lived not too far we all headed back to his. When we arrived back we sat chilling out in Simons lounge listening to music. Lucy was fidgeting a bit so I asked what was wrong. The trousers whilst looking amazing were beginning to be a little restrictive. Simon offered for Lucy to grab something of his to change into so she headed off into his bedroom. I was thinking sweat pants and t-shirt or something similar but when she returned she was just wearing one of his t-shirts, her bare breasts moving under the flimsy material and it barely covered her arse. I knew she had no knickers on so any careless movements and she would be flashing her pussy at the guys. She came and sat next to me and raised her legs up onto the sofa almost certainly giving Dan a bit of a flash. ‘So Simon, when I was looking for something to wear I stumbled across a rather interesting video collection!’ ‘Did you now?’ Simon replied with a cheeky glint in his eye ‘Want me to put something on?’ ‘Sure, pick something I’ll like’ Simon returned after a couple of minutes and pushed the video into the player. He then sat on the sofa with Lucy and me so that Lucy was in between us both. The movie started slowly with a guy and woman on screen kissing and removing each others clothing, then after a few minutes the camera panned round to show a room full of naked guys all stroking massive hard-ons. The guys all then moved in on the lady and began to roughly grope her body and pass her around, mauling her tits and arse. Lucy was breathing more deeply and had moved in the seat so that the t-shirt had ridden up, slightly exposing her pussy lips. ‘So you think I like this Simon?’ asked Lucy. ‘I think you’d love it’ said Simon, a cheeky smile on his face. Lucy reached across and placed her hand on the growing bulge in my jeans. ‘Looks like you like this as well’ she said to me. She unzipped my cock, released my erection and lowered her head onto my swollen member, at the same time opening her legs slightly further and exposing her glistening twat. Simon took that as an open invitation and ran his hand up her thigh and on to her pussy. He slowly ran his finger up her slit parting her pussy lips before easing one finger inside her and pressing his thumb on her clit. He slid his finger back out and you could see how wet she was. Lucy was sucking my cock hard whilst keeping an eye on the screen as the woman was pulled from one cock to another gagging on each cock as her body was groped by the hoard of men. With the angle of Lucy’s body Simon was struggling to work his fingers in her so he dragged her body round so that she was more laying on the sofa. Lifting one leg up over his head so she was now fully exposed he could slide two then three fingers inside her before frigging her pussy to a screaming orgasm. ‘My turn now’ said Simon as he released his cock from his trousers. Lucy swivelled round on the sofa pointing her wet open cunt at me and taking Simon’s cock into her mouth. I positioned myself between her legs and slid my raging hard cock up her in one swift hard thrust making Lucy gasp as I did. Her pussy was so wet that I was almost sliding in and out too easily so I pulled out and pressed the head of my cock against her arsehole pushing slowly but firmly until her sphincter gave way and I slid inside. Her arse was much tighter than her pussy and the combination of the porn on the TV and the sight of my cock sliding in and out of her arse whilst she sucked on Simon’s cock had me ready to cum in no time. I wanted her to swallow my cum so I pulled out of her arse and offered her my cock. Lucy stopped sucking Simon and took my cock that had just come out of her arse into her mouth grabbing my arse cheeks and pulling me towards her. A couple of thrusts from me and I was groaning and emptying my sack into her mouth. I affectionately called Lucy a filthy whore as she licked my cock clean. She licked her lips and smiled at me before getting up off the sofa and stepping one leg over Simon to straddle him, her back towards him and her facing out towards me. With her feet on the sofa and her legs apart I could see Simon holding his rigid cock as Lucy lowered herself down towards his shaft until the tip met her body. Simon ran his cock along her slit, moistening his cock, but Lucy adjusted her body position so that he was pressing against her puckered anus. She slowly lowered herself down, her mouth opening wide as she felt the burning sensation of having her ring stretched by Simon’s extra girth. As she slid down she never broke eye contact with me, gazing passionately at me as she took another mans dick up her arse. ‘I’ll show you a filthy whore’ Lucy said to me, ‘Come on Dan, come and fuck me’. Dan, who had been quietly watching from the sidelines seeing Lucy with her legs spread and moist cunt open quickly responded to her call. He stripped his remaining clothes off and approached her with his cock standing to attention, knelt between her legs and easily pushed inside her. Dan lifted her legs higher so he could get deeper inside her and began to pound away at her pussy his muscular body contrasting against Lucy’s softer feminine form. Lucy was loving this double helping of cock but wasn’t satisfied yet. ‘Come on you bastards, fuck me harder!’ Dan and Simon increased their intensity and began to fuck her with all the force they could. With one hand supporting his weight Dan began to maul Lucy’s tits, squeezing her nipples hard between his fingers. Lucy yelped at this but was clearly getting closer to orgasm. As Dan was fucking her he would grind against her clit each time he was fully impaled in her. This was clearly working, Lucy’s back arched, her eyes rolled in her head and she squealed with delight as her orgasm ripped through her body. Her body shook uncontrollably as these two guys fucked away for all they were worth, Dan’s strong hands squeezing both her breasts, until with one final thrust he groaned out loud and shot his cum inside her. Lucy by now was pretty much a rag doll, entirely lost in the moment, Simon controlling the movement of her body on his cock until he also shot his load deep inside her. Lucy looked so fucking hot slumped on Simon’s body cum oozing from her cunt. I realised how much I got turned on watching my amazing girlfriend behave with wanton abandon and my jealousy was dissipating each time we indulged her increasing demands. After that night we agreed Lucy could fuck whoever, whenever she wanted. Ideally I would be there as well but, to be honest, I was struggling to keep up with her increasing sexual demands so was happy enough for her to satisfy her urges without me from time to time. That usually meant that once a week or so, and particularly if I was busy with work, she would stay over at Simon’s which was good as I knew she was safe over there. One Saturday morning after a night at Simon’s she returned home with even more of a glint in her eye than normal. She gave me a big passionate kiss on the lips and squeezed my cock through my sweat pants. ‘Hey baby, Simon came up with a fun idea for me’, ‘Oh yes?’ I asked. ‘Well, you know Simon is best man for that guy at his football club and that he is arranging the stag night?’ ‘I know’ I said, ‘I’m going to it’ ‘He asked if I would turn up and do a striptease for them. What do you think? Me naked in front of all of those guys, is that ok?’ I had slightly mixed emotions as she had met one or two of the guys before in normal times and I didn’t necessarily want everyone at the club knowing that Lucy was a total cock whore these days, but she assured me she would try to disguise herself and only be there for a few songs and then leave again. So the following Saturday rolled around and Lucy was clearly getting excited at the prospect of showing off in front of so many guys. I was told that I wasn’t allowed to see her costume ahead of time so I was shipped off to the club at about 6pm and waited with anticipation for Lucy to arrive to put on her show. At 8pm the music stopped and Simon grabbed the microphone calling the stag, Greg, up to the front before introducing his ‘entertainment’. At that Lucy strutted out from the side corridor dressed as an almost naked cat woman, complete with mask, whip, long black gloves, lacy black underwear and thigh high PVC stiletto boots enticing wolf whistles and cheers from the 30 or so inebriated lads. She pulled a chair into the middle of the floor and sat Greg down, slowly peeled off her long gloves with her teeth and used them to tie his hands to the chair behind his back. She slowly danced around Greg, occasionally sitting on his lap and gyrating herself against him. She reached round behind her back and unclasped her bra releasing her small pert breasts to more cheers from the crowd, then offered her breast to Greg’s mouth. He hungrily sucked her nipple and breast into his mouth as she gyrated against the growing bulge in his trousers. She then stood straddling him, her high heels and long legs meaning that her butt was inches from Greg’s face. Lucy then bent over and reversed her crotch into his face running her hands up his thighs and squeezing his hard on through his trousers. As she wiggled her pussy in his face she undid his belt, then his zip, pulling his hard cock out of his pants. Greg tried to resist slightly but was helpless with his hands restrained. Lucy then sat on Greg’s lap wiggling her black thong clad pussy on his naked cock. At this stage Lucy turned, back to the crowd and slid her knickers down her long legs, bending at the waist exposing her pussy and arse to those stood at the front. Poor Greg was looking a little anxious about what was going to happen next, obviously worried there was going to be some very incriminating stories about what he got up to on his stag do. Knowing the Lucy of late I could have easily believed that she would have fucked him there in front of everyone but she dialled it down a notch and expertly licked around his helmet and then the full length of his shaft before taking his cock in her mouth. More raucous cheers. I think the rest of the guys thought this would soon end but Lucy stayed crouched in front of Greg, head bobbing up and down faster until Greg’s facial expression changed, he tensed and came in her mouth. From my position at the side I could see Lucy swallowing, not wanting to spill a drop or leave any incriminating stains on Greg’s trousers. Lucy stood, turned to her audience and blew kisses to them as Simon appeared at her side with the microphone again. ‘Now guys, our lovely pussy cat here is scheduled to leave now but I’m sure if we have an extra whip round we can get her to hang out with us for a bit longer, what do you say?’. Big cheer from the lads and with that Simon hands her a pint glass, slaps her on the bum and sends her round to do her collection. As she moved around the room collecting her money naked part from her mask and boots a few of the more drunk lads had a quick squeeze of her boobs or bum not that she objected in the slightest, if anything it just made her more aroused knowing she was the centre of attention. Finally she came up to me at the bar and gave me a wink. ‘Nice show’ I said as I deposited a fiver into her glass. ‘Thank you, I’ve only just started’ she replied winking at me. A couple of lads arrived either side of her offering her a drink as they felt up her arse. ‘Tequila please boys’. The shots arrived, Lucy licked her fingers and moistened her nipples before sprinkling salt on them. She offered a nipple to each of the lads before they all knocked back their shots. The plan was for us all to head into town at about 9pm so Lucy had about 40 minutes of play time with the guys. She spent 20 minutes or so wandering around in her birthday suit chatting to the guys and getting felt up by their wandering hands. I even saw her take one guys beer bottle and thrust it in her pussy before taking a swig and handing it back to him. Shortly after that I’d lost track of her but I knew she’d be up to no good somewhere so set off towards the changing rooms. Most of them were locked but I could see light coming from the furthest one and, no surprise, when I entered she was sat on one of the benches with 6 hard cocks around her. She already had one in her mouth and one in each hand and the guys were squeezing her tits. This was new territory for me as I’d only seen her fucking with friends until now and I don’t even know these guys. She was working her usual magic on the one in the middle taking his cock deep in her mouth, then switching to one of the cocks to the side. What a sight, my slutty girlfriend sucking and wanking these cocks until one by one they shot their loads over her face and tits, as they finished I stepped forward and thrust my cock into her mouth grabbing the back of her head and fucking her face, her almost gagging with each thrust. I couldn’t last long with this action and with Lucy covered in sticky cum. Just as the call came that the cabs had arrived for us I pulled my cock out and wanked it into her open mouth, hitting her face and tits with my cum. Knowing that the club would be closing up soon I walked her back into the bar, grabbed her coat and sent her out into the night to make her way home as the rest of us jumped into our pre-arranged taxis. The lads had clearly enjoyed themselves and kept commenting what a slut she was. They were right, she had become a total slut, but she was my slut and I loved her for it.
