Tease her

"Can my girlfriend watch me dominate you while she hurls insults at you and demeans you?"

"Um, sure. I'll do anything."

"Ok, I'm in apartment 7G. Be there at 7 pm with a large mushroom and sausage pizza from Rizzoli's. Wear what you have on now but be sure you have your sexiest bra and panties set on underneath. Knock on the door and kneel. Hold the pizza on top of your head, and whoever answers the door, tell them 'I'm Amber, and I'm here to be a submissive slut.' Got it?"

"You won't fuck me now?"

"No, later. Get going."

Amber turned to leave, and Julius sent her on her way with a smack to her ass.

Julius was on cloud nine, but he had to set up his girlfriend to be sure she was OK with me fucking other women she considered worthless sluts. The door to the office opened. Pamela, still with her blouse tucked into her panties and no slacks on, smiled at Julius, and walked off, seemingly to meet another prospective tenant. He stifled a laugh as he watched her cute panty-clad butt as she walked off, none the wiser about the show she was putting on or that cum was drying in her messed up bun.

Julius decided to have some random fun with random people.
