I love humiliating slaves and I've got this loser already serving as My human footstool, but that's not enough humiliation for him. I tell him to jerk off whilst I dig My heels in and he of course immediately obeys. he starts to jerk off and he becomes instantly hard. After a while I order him to stop and he does, he lays there hard and in pain under My heels, so I start to play with his cock with My boots heels, as close as he'll get to Me touching it.
