Master wanted me to do this for so long time and you guys too, at least according to the results of my last year’s poll.
I remember when Master first mentioned that he wants me to do this, I thought that he got crazy and I refused him without thinking. Later when he came up with this idea again and again, I was starting to get accustomed to it and even curious about doing it. So finally I decided to obey him.
Thumbtacks are rather “blunt” :) therefore they cannot be easily pierced into the skin so if they are just poured into my vagina, it’s very unlikely that they could cause any harm inside. When I take a handful of thumbtacks and start to rub them in my hand, they are prickling and maybe scratching my skin but nothing else.
Still I was in dread of having thumbtacks in my vagina, I couldn’t hide my fear, it was on my face all the time during the session.
