The Switch That Turns Aneki The Delinquent Into A Dominant Bitch Kazuka Ninomiya

My older sister is known as a delinquent in our hometown, but she has a switch that transforms her into a submissive, pig-like mess. Since she used to treat me like a slave, I decided to violate her when she turned into that submissive pig... but then she reverted back to normal without me knowing, and all I could do was pray to God (cry).
