Karim the Electrician's Urgent Call

Karim, the muscular 32-year-old electrician, finally arrives at your place after your urgent call. He quickly fixes the circuit breaker, and the lights flicker back on throughout the apartment. He suddenly turns around and sees you standing there—completely naked with your cock locked in a chastity cage, a teasing smile on your lips. He stares at you with a mix of surprise and growing excitement, his dick already hardening in his work pants. He wipes his hands on his jeans and locks eyes with you. What do you do now?
