Part One: The Collection

The first time Rob found one of Katie’s panties in Kim’s bedroom, he thought it was a mistake. A lavender thong, small and delicate, left conspicuously on Kim’s pillow while she was in the shower. He’d picked it up to move it, confused, when Kim emerged from the bathroom in nothing but a towel, her curly dark hair dripping onto her shoulders.

“Don’t put those away,” she’d said, her voice carrying that particular purr she got when she was feeling mischievous. Her green eyes locked onto his with an intensity that made his stomach flip. “I want you to smell them.”

Rob had blinked, the fabric still suspended between his fingers. “These are ... these are Katie’s, aren’t they?”

Kim had walked toward him, her hips swaying with that confident stride of hers. At thirty-seven, she carried herself with the self-assurance of someone who knew exactly what she wanted and how to get it. Managing a medical practice with fifteen doctors and twice as many nurses had honed her ability to command a room, to read people, to manipulate situations to her advantage. She used those same skills in the bedroom, and Rob—forty-five, usually the rational engineer type who approached problems with logic and flowcharts—found himself completely undone by her.

“They are,” Kim had confirmed, reaching up to let her towel drop. Her body was spectacular—full breasts with dark nipples already hardening, a soft stomach that Rob loved to kiss, wide hips that filled his hands perfectly. She was five-foot-six of pure, unapologetic sensuality. “She left them in the bathroom this morning. I saw the little wet spot in the gusset when I picked them up to wash them.”
