"No, stop, or this is going to be over very quickly, and the only satisfaction you'll get is having beat me." He dropped the rope to take her hands in his and move them away from his pants. "That might be enough for you, but I enjoy other things."
Holding both of her thin wrists in one large hand, he picked up the rope and tossed the end of it around the bed post. "You don't have to just let me tie you up." He winked. "But think how disappointed you'd be if I didn't play along when it was my turn?"
