This is how i was introduced into tease and denial about 10 years ago. my Girlfriend had convinced me to let Her tie me up,i was bound naked to a chair gagged and told i had to beg Her to let me cum. Well i am gagged with a hand towel and duct tape so i can't speak and this is when She began. She brought out a small make up brush and started slowly running it up and down my cock the feeling was like nothing i had ever experienced,She would tightly squeeze my cock in Her hand and lightly run the brush over the head of my cock, the desire to cum was almost instant, it was just a few minutes and i was squirming in the chair trying to talk through my gag. She kept asking me if i wanted to cum and i kept shaking my head yes,Her reply was you have to beg Me not shake your head at Me. After about 30 minutes She stopped smiled and said thats all for this week if you are good for the next 2 weeks W/we will try again, but the rule is you have to beg for release
