I love the absolute mind fuck that goes with wanting to cum and then regretting then regretting that you did. I fantasize and being post orgasm tortured for around an hour with the entire goal of making me cum a 2nd time. Literally taking no break from stimulating my cock, pushing through my defiance and any safe-words, and working me over until I cum or until I am exhausted.
Since I am not into guy on guy I tired to find some femdom ones. I had mixed results.
