My boyfriend (27M - bottom) and I (28M - top) have been dating for 2 years. I have gradually started fucking him harder and harder. He loves it when we are not using lub, when I pound him extremely hard, when I do whatever I want to him. He loves it when I talk dirty to him, he has asked me to call him my whore. He has asked me to bite him and to practice consensual non-consensual sex with him. I honestly love it. The thing is, I'm not very creative, so I'm running out of ideas of things I would like to do to him. We agreed that we'll fuck on Friday, and he ask me to be more "sadistic".
I need ideas. As a sub bottom, what thing does a top do that turns you crazy? What do you like? Do you have any reference on porn videos that showcase a very Dom top using his bottom?
