Most men can be very sensitive about having their assholes fingered. Their masculine pride rejecting anything that even gets close to their virgin ass. Well, to be my slave, you have to be able to take what ever I dish out… even if that means forcing my entire into that tight manhole, thrusting my arm in and out like a piston. Your moans and screams only fuels my desire to keep plunging my hand deeper into my pathetic whimpering puppet.
