i'm sure she looks terrible naked.
i would tell her to pull her top down below her breasts but not to expose her gut while i smashed.
then i would try to eroticize her feelings of embarrassment, shame and anger into a fuel that would sustain my sexual impulses.
at some point during sex i would eventually start feeling up her gut and get angry...soft touches would turn into a rain of heavy blows.
non stop uppercuts to the ribs as i pin her legs behind her head with my feet and continue to do jumping jacks in her anus.
