Chris and Bruce Sitting here embarrassed with myself again but realising I can't stop myself with what is happening but I have promised I would tell you all. Chris rang me up on Wednesday told me to wear trousers blouse with ordinary undies and buy a dog collar to fit me this obviously was the first part of the blackmail and humility and to meet him at his small garage with Bruce. I will be honest that Thursday morning seemed to fly because next thing it was time for me to walk with Bruce the short walk across town to meet Chris. My heart was pounding by the time I got there and feeling that everybody I saw on the way knowing I am willingly going to let another man other than my husband watch me strip but also Chris watching me having s** with a dog. He had the garage set out just like a rest room with sofa a couple of chairs with a coffee table complete with water and kettle even a small mattress. At first the conversation was just about normal sort of things leading me into a false sense of security but after about 5 min he reminded me about the blackmail and controlling I had agreed to when he caught me with Bruce telling me also he was looking forward to a repeat performance (he really knows how to get me embarrassed) He told me put on the collar myself I had bought and then strip so he could see me in the flesh and to get down on all fours just like Bruce and to crawl across to him so he could have a feel before I have to get ready for Bruce but by now Bruce was starting to get frisky because nowadays when we are alone at home he knows when I strip off he knows it is "playtime" although I have only let him have me three times but already he knows what is coming. Chris was made up watching meaning Bruce prancing about but adamantly saying not to let Bruce Mount but first for me to work on his D*** which was really starting to stick out of his "sheath" all the time really getting worked up himself to the point of unzipping his trousers waving his rock hard D*** at me saying something like he wants sorting out as well afterwards but at that particular moment my priority was Bruce because he was really licking deep in my F**** and although Chris was watching I was getting more and more worked up and I have got to admit right at that moment I could feel myself trembling with the organism which felt like a steam train hitting me when I started to actually C** at this point I was completely out of control of my own feelings and Bruce was also getting out of control because all he wanted was to mount me and I should be ashamed of myself but I actually wanted to feel him inside me. I could feel him actually start to jump up with his front legs wrapping around my fat belly his D*** starting as usual prodding against my bottom until he actually started to push inside I know it is very morally wrong but at that point all I wanted was Bruce inside me once he was "connected" as the last previous times the frantic humping started until I could feel him actually growing inside me until I was completely stretched this is when he stopped humping but also embarrassingly he actually like last time jumped off but staying "knotted" we were bottom to bottom and this is when Chris started wanking furiously over my head and face openly describing what me and Bruce looked like and holding onto my nipples describing how hard they were the next thing he actually started coming but Bruce was still "knotted" but I could feel him starting C** and then fall out of my F**** this is when yet again Chris took delight in watching Bruce's s**** dribbling down my legs but also saying I hadn't done as I was told meaning I had let Bruce have me before I had sorted Chris out but next time I better do as I'm told (h*** I didn't think there would be a next time) but he was quick to remind me what had just happened and that I was his slave on a Thursday afternoon from now on and actually secretly I suppose I wasn't going to argue but found it a turn on but right at that moment I was still completely naked on all fours with s**** all over me off Bruce and Chris fortunately Chris had bought a bowl for some water which I boiled in the kettle to wash all the s**** of not being still naked Chris took delight in describing what I looked like and what had just happened and next time he wants to see Bruce take me face-to-face so as to speak Thursday finished off with me having to walk back to my house through the town with Bruce obviously reflecting what I had just done and agreed to carry on doing and yet again here I am a 30 year old chubby married woman being ordered by a much younger guy
