Lemme get this straight. Noelle got so fucked up from losing Dess and Kris becoming distant that, as a coping mechanism, she became a masochistic bislut that projects her dead sister's traits onto Susie, because she misses the excitement those two brought into her life and years for a powerful, protective female figure.
This would lead to varying degrees of kinky H scenes in any other story. I'm shocked Toby can restrain himself.
