That didn't mean they couldn't be useful, and if they lived they were going to be useful. I didn't intend to make slaves of them, but I was going to e...d up in charge of them and they were going to do things I wanted done, if they got to live.Caloe and Shata finally decided they had all the information that I had, and they left me in peace. I was glad about it. I didn't mind telling them what I knew but I didn't know enough about it to matter. They kept coming up with questions that I couldn't. Then one night she took it one step further by saying that she had just heard her father go into the bathroom. It was about 1 am and she asked me what she should do. I was a bit lost for what to say as I didn't want to be guilty of grooming her so I asked her if it happened often and how did she know it was her father and not her mother. She then startled me by saying that she had, on occasion, peaked out of her bedroom door and seen him.I then asked her if she thought her father had any. The important thing was that we stripped in the room and then strolled to the scaffold naked before climbing up and fucking our brains out. After an extremely satisfying fuck session, we got down from the scaffold. I started the pump and we bathed in our open-air super size bathtub.Next day, I fucked Mansi in our open-air bathtub. It was a great feeling of fucking my sister under the hot sun while fresh cold water from the pump was splashing over our bodies.And probably we overdid that day. We. But the fact of the matter is that shame within the context of BDSM has the effect of producing a brain chemical cocktail. I'm not sure exactly what chemicals are involved. Maybe it is a cocktail of adrenalin, serotonin, norepinephrine, endorphin, etc. But being shamed or humiliated by a Mistress can induce a sexual rush. Not all men get the rush, but for those who do, it is a powerfully addictive d**g. Humiliation is also a way of desensitizing ourselves to the things which shame us and trap.
