"Let me worship you, please. I'd be such a good boy for you." It doesn't take a rocket scientist to figure out relationships, but when Lily-an actual rocket engineer-decides to try something new, neither relationships nor rocket science prove to be easy. When her best friend Tala drags her to the local swinging club, Lily walks straight into a dungeon filled with leather, kinksters, and Mark. Mark stretches on the cross, held by leather cuffs on his wrists and ankles, but Lily is the one that's bound. He's gorgeous, driven, and eager to show her the ropes. There's only one problem: Lily is so new to the scene she's not even sure what "the scene" is, let alone how to be a domme in one. He awakens her desire for dominance, but is it enough to satisfy the darkest of his needs?
