The art of keeping a girl around to screw when needed.
This is something I shamelessly do all the time. I have my good girl, the one I adore, but sometimes, you need to have something else on the side, the backup plan. I always have time for my good girl, but when there are those days when she does not want to put out, and you need to relieve some stress or just a good old fashioned blow out, you need to use the backup plan.
Now the backup plan will only work if you keep them close, not too close, but close enough. I have 3 different cell phones, my real phone and the 2 I use for the backup plan girls. I always try to keep in touch with my backup plan, just to string them along. Text them, say nice things, make them feel sexy, buy them things when I have to- to keep them sedated.
Reading this story from the OP, I feel its a backup plan.
