[F]un with [m]y wife

My wife and I recently got into bdsm. We dabbled once or twice before, but I never understood how much pain she found enjoyable until just recently. This Sunday we had the house to ourselves. She asked for lunch, I told her I already know what I want to eat, which is my typical response, joking but not really. But to my surprise, she lays out spread eagle. I started by handcuffing her over her head, then pulling her shirt up to use as a blind fold. Surprise,no bra! I licked and teased her breasts, alternating pressure and sucking and flicking. My hand drifted down and grasped her crotch firmly, pulling up, rubbing back and forth.I proceeded to pull off her shorts and panties, stopping to inhale her scent. I LOVE a woman's scent. I prefer sex pre shower. I teased and licked but nothing too gratifying. The Wartenberg wheel was next on the menu, but I dipped it in ice water first, dripping some water onto her clit, then each of her nipples. I gently ran the cold wheel around her areola, gently and slowly, then up and over her now erect nipples. The skin of her breasts became taught. Flipping the wheel on its side I dragged it down the center is of her chest, leaving light red trails till I stopped at her pubic bone. I dipped the wheel in water again, rolling ever so lightly down her hood, over her clit and down her labia, continuing down her inner thigh, rolling back up and proceeding down the opposite leg. Sipping from the ice water, I proceeded to envelop her entire mound with my mouth, flicking her clit with my tongue, dragging it over her labia from left to right and back. Then I pulled back and slapped her sex. She snapped back and gasped.
