An Electrifying Science Experiment

Our step-brother’s body is bound from his feet to his Adam’s apple, every strap pulled tight. The plastic table beneath him squeaks when he tries to move. His cock stands hard and exposed—circumcised head already glistening. We touch the first electrode to the shaft and fire a quick jolt. He bucks against the straps and spits out a curse. The word hits the air like a slap. Blond hair sticks to his damp forehead as he twists. His brunette stepsister doesn’t like rude language, so she twists the dial higher. The next shock lands dead-center on the swollen head, and the sound that rips out of him is half-scream, half-prayer. We hold the contacts on his balls this time, draw out the current, and watch his whole body lock rigid. Every muscle stands out while the current runs its cruel path. When we finally let go, spit drips from his open mouth. His chest heaves. The room smells like ozone and sweat. We smile at each other and lower the contacts again, hungry for another filthy word so we can punish him harder.
