Its interesting that you've taken an orgasm denial approach and it definitely is fun. With the ending, are there going to be any sensory deprivation scenes, where only her coupling areas are exposed?
I generally write stories with a reluctant ENF (embarrassed nude female) with public nudity & sex theme, but other things will creep in there from time to time, even a little femdom. I write more of a dark comedy with a sci-fi and erotic twist rather than straight out erotica....
