In the dimly lit playroom, a dominant figure attaches a TENS unit to a shallow urethral probe inserted into their submissive partner. The sub, bound and gagged, squirms as electric pulses course through their sensitive genitals, their pussy leaking with arousal. The dom expertly adjusts the settings, drawing moans and gasps from the sub as they edge them closer to orgasm, only to back off, prolonging the intense, electrifying pleasure.
