A woman in a leather miniskirt and stilettos staggers down a darkened corridor and rings the buzzer beside a bolted door. The man inside interrupts his bare-chested boxing workout to let her in. “I’m busy,” he grumbles. “Please,” she pants through gritted teeth. Then she jumps him. They square off in a round of violent yet balletic sex. He hoists her off the ground and onto a counter; she retaliates by slamming him into a wall. He paws at her breasts while she claws at the tattoos on his back. Off comes her shirt, and he stealthily peels off her underwear. Soon they’re naked on the bed and she’s straddling him. They growl, groan and grunt like the Williams sisters at Wimbledon. As they arch together in one final thrust, the whites of her eyes turn solid black.
