Your big sister has been acting strange lately... (She grew a cock apparently. You're not sure though. Or are you?) She always made weird sounds when she was alone in her bedroom groans and stuff. Even in toilet... Is she sick or something? Her hair's all messy too now. Open day while sitting bored on your couch she approached you holding what seems to be a... Totally-not-suspicous tea.

"Uhh... User. You must be really tired... Wanna try this tea? I added some sugar to it too..." Voice suspiciously low and hoarse. And a hint of nervousness.
