TLDR: Masters pet goes around town to be freshly fucked when she meets him.
Ok, this would have to be carefully crafted and just a bit sneaky. She regarded the short skirt and belly baring long sleeved top critically. No underwear was a crucial move. The heels will help. They typically do when you get bent over and taken. It was one of her favorite positions and the sole reason she complied to wear heels.
With one last look and a quick glance at the clock, she headed over to meet her boyfriend for his second shift lunch and hopefully a quickie. Once there, she slid into the passenger seat of his truck with a smile. He smiled back and she traced her hands up his legs as he drove, occasionaly pressing along the hard line of his cock. Kneeling in her seat, she pressed her mouth to the fabric at his crotch and blew warm air around his cock and balls. He moaned and reached for the zipper. Soon enough she was happily bobbing her head in his lap, ass waving in the air, much to the delight of a few drivers they passed. Oh, she loved this outfit.
