Mark was getting annoyed. With those pictures hanging over his head, and Diana using him at her whim, life was getting annoying. Even the substantial raise that had accompanied his servitude was little compensation for being, essentially, a call-girl-boy. What could he do, though? All he knew is that he had to think of something.
At that moment, his phone rang, and Diana's voice greeted his ear. "Sapphire. Mark, I'm taking a client to dinner at 6pm, and you're coming with us. Dress as sexy as you can. Meet you at the restaurant at 5:45 for drinks. Bye."
Mark showed up at 5:45 on the dot, ready for whatever was to come. He had changed into his best suit, which fit like an old glove, showing off the contours of his muscular body. He wore a tight t-shirt underneath, black, that showed off his six-pack and pecs. He was definitely dressed to impress.
At 5:50, Diana walked in with her client. Her client could have been Diana's twin sister in most respects. Tall and dark, with skin the same shade as Diana's, they were even dressed alike in professional business suits, except Diana wore slacks while the newcomer wore a short skirt. The only difference was that the client was more voluptuous than Diana; Mark estimated her breasts at least a 34c, maybe larger.
"Cassie, this is Mark. Mark, this is Cassandra, CEO of the company that supplies us with all of the proprietary hardware that makes us great."
Cassandra laughed and extended her hand, which Mark shook cordially. "Pleased to meet you," she said huskily, her voice a low growl that Mark loved immediately.
The dinner went splendidly, Mark, Cassie, and Diana hitting it off wonderfully and having a great time. Most of the way through the meal, Cassie excused herself to visit the rest room. Diana slid her chair next to Mark and reached under the table, grabbing his genitals in her hand and squeezing softly. She leaned close and whispered in his ear "I know you want her. How could you not? She's gorgeous. And you get to have her, tonight. When she comes back, I'm going to go to the rest room. One minute later, you will too, only you'll come into the women's room, I'll be waiting, and I'll tell you what you're going to do." When Cassie returned, Diana left, followed shortly by Mark.
When he walked into the women's room, Diana grabbed him and pulled him into one of the stalls. She wasn't wearing anything below the belt. Working quickly, she yanked down his pants and underwear and pushed him down on the seat. She straddled him and lowered herself onto him, facing away from him. She spoke back over her shoulder as she ground into him. "You're going to take my limo... oohhh... and you're going to find a way... oh, yeah, there... to fuck her... in the limo... aaaahhhh... it has to be... in the limo...I won't accept failure. And it should be as kinky as possible. Do you understand?" Mark grunted a reply, and Diana shuddered as she came. Climbing off, she reached into her purse and pulled out a towelette, and tossed it at him. "Wipe yourself off and rejoin us at the table" she said as she redressed quickly and stepped out the door. Mark rejoined them at the table a few minutes later.
