FemDom Beginner

So... My man wants me to dominate him. The fact of dominate my bf sounds very fun to me and something new for both of us. We’ve been dating for a year in a long distance relationship, never ever met in person, and now he’s moving to the same place as I’m living now. He wants me to humiliate him, fuck his butt hole with a panty that also has a dildo on it. It excites me just thinking about riding on him with the fact that I’m gonna be the one inside him. He showed me some videos of FemDom but I want it to make it as sexy and sensual as possible and BDSM. If any of you ladies had this experience already or you still doing it give me some advice to drive my man crazy with FemDom. I want our first sexual encounter to be perfect as he was expecting it.
