Capybara
The chuuni Haein became pretty submissive and obedient after that night.
Well, if I really did what she said I did I suppose there would be no other way for her.
But she wasn't the only one traumatized after what happened. Although I somehow ended up emerging out of the whole ordeal intact (literally), it was such a disgusting and frightening experience.
Too frightening in fact that the first thing I did the morning after was killing the landlady again so I could start gaining power as soon as possible to ensure that nothing like that could ever happen again. I felt a bit sorry for the kind lady as I could foresee that this becomes my routine for every cycle.
