It's not like I really try to think of new raunchy things to do every time we walk in the bedroom. More like I'm up for almost anything, I trust him, and occasionally he orders me to get on all fours with a blindfold on, or something comparable, and I let him do what he wants. Giving up control is my game, and taking it is his. We are perfectly sexually compatible, and that is what will keep it interesting and exciting.
As for the slap... I'm actually a little surprised I'm about to share this, but I got my first face slap a few weeks ago. It wasn't hard by any means, but it was sure firm. He was fucking me from behind, pulled my hair a little, and reached around to slap the side of my face and told me I'd better come for him. Naaauuuughtyyyy!
