Well I suppose it turned me on that whilst I was fucking sue her ex husband was watching ... I took her upstairs where we spent the night . Things were going well and enjoyed going out with her. I was her guest at her Christmas works function. All the men in tuxedos and the women in cocktail dresses, she looked extremely sexy. There were a lot of very wealthy businessmen and concluding the meal they had an auction to raise money for some charity. I felt a bit out of my depth as I'm in the forces but just rolled with it. She was looking stunning and after the meal she went to chat business with a couple of her clients while I went to the bar to get a round of drinks in and chat to her friend. I noticed she was laughing and joking with a couple of very good looking slightly older gentlemen. I lost track of were she had got to as I was chatting to one of her friends, so I decided to look for her. I couldn't see her but I needed the toilet so as I walked in there were a few others were stood at the urinals. As I was taking a pee I realised someone was in the cubicles behind me getting a seeing to ! A man's deep guttural moan and a woman's voice, saying in a whisper fuck me fuck me fuck me .... We all started laughing and the lads started egging them on ... go on son, give her a good seeing to ... I walked out of the gents smirking to myself and carried on looking for sue. All of a sudden it dawned on me that sounded like her voice in the cubicle .... I turned around to see her sheepishly leave the gents adjusting her dress and hair. She didn't see me and walked past in the crowded bar. Oh my god my cock sprang to attention. I met up with her at the bar with a group of businessmen she had been chatting to before. They were all smirking and laughing as sue gave me the naughtiest kiss ... I could smell and taste cock on her breath and noticed a couple of small damp patches on her dress. I should have been angry but something inside made me feel so turned on. As we made our way back to her house at the end of the night we got through the door and into her kitchen where she sat on her kitchen table and pulled up her dress to reveal her see through black knickers and her soaking wet pussy underneath. I sank to my knees and kissed her shoes and worked my way slowly up her legs smelling her sex and the potent smell of another man's cum in her ... her pussy was soaked and she placed her hands on the back of my head as I nuzzled and kissed her wet panties ... I ripped one side then the other pulling the front and the gusset sliding out from under her so I could use my tongue on her clit over and over until she came on my face ... I took her upstairs stripping each other as we went I bent her over and slid my huge hard cock into her ... she was loving it as I fucked her doggystyle hard and fast. I held her hair whilst my other hand played with her nipples and teasing her clit as I slid in and out of her knowing how much of a dirty naughty slut she had been. She started to cum on me and this set me off as I added my cum to hers and her clients. We collapsed together and ended up having a few more sessions before we drifted off to sleep. This was all new to me, however I was enjoying it and after a 15 year sexless marriage sue was definitely catching up for lost time ... There are a lot more adventures to come ...
