Under the harsh glare of the dungeon lights, a couple, their identities obscured, indulge in their darkest desires. She's spread-eagled, arms and legs restrained, a ball gag filling her mouth. He circles her, a wicked grin on his face, a cattle prod in his hand. He touches it to her naked skin, and she jolts, a muffled moan escaping. He traces it down her body, leaving red marks, then pushes it into her pussy. Her scream turns to a moan as he turns it on, the electric current pulsing through her. He replaces the prod with his cock, fucking her hard, their bodies slapping together. She bucks against her restraints, begging for more, her eyes wild. He obliges, fucking her harder, their bodies slick with sweat, until they both come undone in a explosion of pleasure and pain.
