Two MILF dommes on one man: the first lady is whipping his balls while another is hitting penis with high voltage sparks
Mistress is using balls destruction as a way to stop that man from jerking off: spread-eagle bondage, balls beating and trampling are doing the job fine
Dominant brunette is tying up cock and balls tightly in anticipation of degrading a amn with her strap-on cock
Black slave is cuffed to the bench and whipped by girls while his cock is clamped so he can't move at all
