So you want to cum to me, cum to my body? Your only allowed to receive pleasure from jerking off to me if you also receive pain, so heres what your going to do, your only going to touch yourself when I tell you to, your only going to stroke how I tell you to, when I say stop you will stop, when I tell you to punch yourself in the balls you punch yourself in the balls, and then stroke yourself again to bring more pleasure after the pain and then more pain after the pleasure, only when I am satisfied with you following my instructions will I allow you to cum.
