One evening while relaxing in front to the TV, my girlfriend comes down, dressed in a tight black, slinky dress, her hair is all done up, she looks exquisite. She stands with one hand on her hip, her long legs, enhanced by the shear stockings she was wearing; she takes a sip of wine and then tells me to go upstairs to the bedroom… At last I think, my luck has changed, tonight will be a night of passion, oh if only I had known. I go upstairs and wait, she soon appears in the doorway, walking in she instructs me to remove my clothes and sit on the chair at the end of the bed. Not wanting to miss a thing I quickly do as she asks. She moves behind me stroking my chest, then pulls one of my hands round the back of the chair, quickly snapping some cuffs on, thinking that I was in for a kinky session with her I gladly let her take my other arm and place it in the cuffs, I try to pull my arms away, but she has linked them through the back of the chair so I am now secured to it. She is not finished, she takes a scarf and ties my left leg to the chair and then the same with the right one. Noticing that I am hard by this point she starts to stroke me, my breathing becomes heavy and she says “you’re enjoying this aren’t you?” “oh yes” is all I can manage to reply. Suddenly she stops, stands goes to my bedside draw and pulls out my stock of her dirty knickers, stunned, my heart starts to race. She simply says “So?” I mumble and babble trying to make a coherent excuse… “Enough” She dumps the pile on the bed in front of me. Telling me that tonight will be a change in our relationship and that tonight will be a change in my life forever. She gets up and walks out of the room. She is soon back carrying another pair of her knickers… “These are the ones I wore at work and to the gym today” she says, taking them she pulls them over my face with the crotch over my mouth and nose. She sits on the bed in front of me, her legs slightly apart, I can see up her skirt, and I notice the damp patch appearing in her white panties. She looks at me with a smirk on her face, “I have been looking on your computer” again my heart starts to race, oh my what has she found, “Very interesting, very interesting indeed!, We are going to talk about this later, but just be sure, I now know what you really want” and with that she walks out the room, closing the door behind her… “I’ll be back in a while honey… enjoy!” My mind is in a spin, wondering what had just happened, what was going to happen next, had she really found everything on my computer, I had been so careful to hide everything away, the stock of stories I had downloaded, videos, and pictures, my kinky secrets stored, my private collection, the life that I am so ashamed of. Soon I hear the front door slam shut and then silence. Minutes turn into hours, the night draws in outside, and all I can do is wonder, left with her scent with every inhale of breath, keeping my aroused and in a constant state of frustration. My mind continues to race, what is she going to do with me? Is she going to leave. I continually tried to analyse if she was happy or mad with me, she had held herself together so well, not giving anything away. What did she mean by a change in our relationship, and a change in my life, was she going to leave me? All these questions combined with the constant state of erotic frustration I was in was driving me mad. About 3 or maybe 4 hours later, I hear the front door open, and voices, my girlfriend and was that another mans voice? Surely not, she had brought friends round and was leaving me here while she entertained her guests, how wrong I was. The door opened and in walked my girlfriend followed by a stud of a man, who was smirking at my predicament, stunned I asked what was going on, she simply sat on the edge of the bed in front of me, after pulling her panties off my face she hitched up her dress and removes her panties, which were clearly wet, rolling them into a ball she rubes them over my face, and then shoves them in my mouth, her scent on my face was over powering. She then took a stocking out of the draw and tied it as a gag. All the time, her friend simply smirks at me. Standing up she takes him by the hand to the bed, and they started to kiss, soon clothes were being ripped off and they are both naked apart form my girlfriends stockings. Soon she is giving him a blow job, sucking him for all she is worth, it looks as if he is about to blow, but this man has stamina, soon they are making out, to my horror they do not use a condom. I can see clearly his large member stretching her, I can see how wet and turned on she is, ravaging every inch of him, their bodies entwined; now glistening with sweat from their exertions. After only minutes she starts the first of many orgasms, they carry on for what must be nearly an hour, most of which my girlfriend is riding the crest of orgasm followed by orgasm. His thrusts become more laboured and I can see that he is near, but what happens next shocks me, even with everything what has just transpired. I clearly her hiss through clenched teeth “cum inside me, cum deep in side me, I want your cum now”. Soon he is pumping for all his is worth, leaving his seed deep inside my precious girlfriends’ pussy. She rides to yet another climax and they lay entwined in each others arms, him still inside her. I was so shocked, she had never allowed me to cum inside her. I see he is whispering something to him and he gets up and comes my way, removes the gag, grabbing the chair he spins it round so that I have my back to the bed, then simply pushes the chair over so that the back is resting on the bed, with this view I look directly up the bed into the cum soaked pussy of my girlfriend, who then states “you are about to start the life to which you are best suited, that of a cum slut” and with that she carefully crawls down the bed and before I know what is happening she jumps over and sits on my face. “clean me out, clean me out now and clean me out good, I don’t want to be getting pregnant, do you duty cum slut and get used to it as you will be doing this when I am with all my boyfriends from now on” The musty stench of his cum and her pussy are intoxicating, the cum dribbles out of her and I get the first taste in my mouth, the humiliation is intense, and the sexual frustration too much, I am soon eagerly licking and sucking every inch of her, brining her to one last orgasm over my face. After she has recovered she stands and asks me how I like my new life, the humiliation is too great, I just look deep into her eyes, she can tell how much I enjoyed submitting to her in that way. She smiles, takes her friend by the hand, saying “we will talk about your new life later” and with that they go downstairs.
