we used to go out at the weekends seperatly and meet up at the end of the night but sometimes before I would let her out I would get her to lift her skirt up and pull her knickers open at the front, and wank myself off all over her pussy and panties. I would then make her wear them like that all night so if she let anyone touch her pussy they would get covered in my cum as well as her cunt juice..! 

Later on in our relationship this evolved into her taking someone into the toilet and sucking them off before wanking them into her knickers then she would jump into a taxi come home to me and I would lick her hairy pussy clean before fucking her like crazy and shooting my cum in her.

Towards the end of our relationship this again changed as I talked her into getting fucked by other men. At first she was reluctent and the first few times she lost her nerve couldn't go through with it, I was just about to give up on the idea when one friday night she came home all sheepish sat down next to me and said "well are you going to put your hand in my knickers" as I put my fingers in her panties I could feel she was soaking my fingers just slipped straight inside her pussy I looked her straight in the eye and asked "Have you been fucked" she just grined and shook her head. I dropped to my knees hitched her skirt up and pealed her soaking wet knickers down to her ankles, as I moved in closer I could see her swollen piss flaps and her matted ginger pubes the smell of cum was overwhelming. As I started licking her cunt I couldn't control myself and ejaculated in my own pants.

We stayed together for about six more months and she continued fucking other guys at the weekends never telling me who they were or where they had fucked her but I would get some idea when complete strangers would walk by us and say hello to her and not me....
