Spanking is erotic enough at the best of times but spanking in the shower. Get him to suds you down in the shower, massaging every inch of your body in the warm water, without touching any of your most private parts. Then, turn away from him, still standing, and put your hands against the wall. Next, jut out your ass into the stream of the warm water and have him spank you with his bare hands until you tell him to stop. The combination of your wet ass, the feel of the water and the sound of the wet slap will be a huge turn on for both of you. From here he can do whatever he wants, we’re more than sure you’ll be ready. Depending on the size of your bath or shower, you could also do this by lying face down across his lap in the water in your bubble bath. With just your booty popping out from under the bubbles, have him spank the soap away.
