Spank him
Most girls get a casual spank from their partner from time to time but trying out spanking on your guy can be a bit of a shake-up.
"Sit in a straight-backed, armless chair and order him across your stocking-clad thighs for an old-fashioned hand-spanking," says Nichi, "Place one hand on the back of his neck and slightly cup the other as you deliver slow firm strokes on the fleshiest part of his behind until he’s nicely pink."
If you really want to take it to the next level: "Get him to count the strokes out loud and say ‘Thank you Mistress/Goddess' or any other superior term you see fit!"
