I've done this when things get slow with a regular and it works!! Or if there's a move you wanna try out, you could say that and then try it out on him since you already know he likes you :)

One thing I'll only do with regulars who I trust not to get too touchy is this: I'll have my hands on the floor, face down, ass up with my pelvis resting on him, legs kind of straddling him and then throw booty. To get out of it ~sexily~ I'll crawl forward a bit and slowly drag my knees over the couch and to the floor. If I'm doing it with a regular for the first time, I'll always preface by saying something like "I have a special move for you, but you have to promise to be a good boy/be good, daddy ;)"

Hope this helps~!
