Rencor's Frenzy - an Alien Slime Humiliation Erotic Short

This is a 3,000 word erotic short with themes of humiliation and BDSM
Terra had thought she had figured out living with an alien parasite. Life had been what she now deemed normal and she didn't think the alien could think of anything to surprise her anymore. 
Until Rencor told her that it had a mating season.
For a few months, she would be driven to near-madness with desire, with only her parasitic paramour to ravish her. Just how far will lust drive both human and alien?
