She thinks they're done. He says, "Not so fast. Now, on your knees."
Sybil Anderson is caught in a dilemma. She's been in the BDSM scene long enough to know what she needs, but the man she wants doesn't want the same things she does. Oh he's dominant; there's no doubt about that. He'll demand, he'll tie her up, he'll torment her with pleasure, but he refuses to lay a hand on her lily-white rear. And that's what she wants most.
Concerned that he'll lose control, Kellon Marecek has always avoided the spanking part of BDSM, but when he meets Syb, she wants more than he's ever given. He'll need to change now or lose her. And he's not giving up Sybil for any reason, not because of his reluctance and definitely not because of her rampant disobedience.
