Please note that nothing in this story is true - all characters and events - well maybe not all events are a figment of my imagination.
Nikki and I had always had a very open sex relationship. We would share all of our sexual fantasies and, while vigorously fucking her tight pussy, I would tell her that I was imagining fucking my co-worker or next-door neighbor. Not that my girlfriend wasn't sexy - she had 36D breasts, a great set of legs and the tightest, sexiest ass that I had ever seen on a lady. She too, had some really wild fantasies and loved to act them out with me - I remember that on one occasion she borrowed an outfit from a friend and dressed up as a nurse to give me my 'medication.' By the time we were finished, we had messed her friends uniform so badly with her juices and my cum that we had to replace the outfit. But, there was one fantasy that both of us shared but never had the guts to try - Bondage and Domination. (I know for a fact that she used to wet her panties just thinking about it, but she would never admit to that).
Anyway, we were both sitting around and reading one day when she suddenly turned towards me with the type of smile that a naughty teen would have on her face after giving a good blow job and asked me if I would like to try some bondage. I was dumbfounded that she would pop the question to me just like that and just replied with a look of surprise on my face. She laughed at me and simply leaned over and whispered that it was mutually agreed on. Later that night I asked her if she was really serious and without hesitation she replied that she was. There and then we agreed that the next day I would buy what we needed for her discipline and that when I got home from work we would begin to work on our master and slave relationship.
The next day all I could think of was my girlfriend's discipline and when I got home that night with my box of 'tools' my cock was rock hard. I entered the house and when I got to the bedroom, there she was, clad in black underwear and lying sexily on the bed. She said nothing, only that she was ready for her discipline. We quickly agreed on a word which she would say to stop me if the pain got to intense - Pamela, the name of the neighbor who I fantasized about often.
