Tough lass stands defiant, her nipples hard and ready for the electric punishment she's been promised. The dominatrix, clad in latex, attaches clamps to the vulnerable peaks, causing the minx to gasp. As the current flows, her body twitches, but she remains stoic, refusing to cry out. The mistress, admiring her resolve, orders her to pleasure the thick, hard cock of a nearby stud. The girl, bound and helpless, takes the massive member into her mouth, sucking enthusiastically as the voltage continues to pulse through her nipples.
