Steam Powered Sex Machine (Steampunk Erotica)

Lily is insatiable. To keep her satisfied, Patrick has no choice but to build something that will never get tired- a sex machine that can keep up with her every tireless whim. Will it be enough, or will she wear it out just as she does him? Warning: this 4000 word erotic short story contains explicit sex, sex toys, multiple orgasms, and a sex machine that just won't stop!
