I love having my man naked around me. So that I can see all of him any time that I desire, and I can see the mood of his cock as well. Touching is easier, grabbing, too. Grabbing the parts that call to me, whether it's his hair that I want to pull, or his balls that seem to need a tug. Above all, the fantasy that gets me off over and over is the element of surprise in bending him over whatever is handy and just taking his ass, claiming it as mine on a daily basis. Not for his pleasure, for mine. The satisfaction of fucking what is mine. Like a dog pissing on a post. The knowledge that I can leave him wanting or let him come, and he will love it either way. Fucking hot.
