The stupidly powerful Shirogane Group.
Trina is the daughter and heir to this group.
As the heir, she seeks perfection in everything she does, making it no mystery that she is adored by everyone as the school president.
On the other hand, she is also a masochist bitch who faithfully pleases the master she chose, Sado Yuuji.
As she gives a speech on stage to all the students in the school about the rules of the school, a huge vibrator is fucking her underneath her skirt...
She tries her best to keep it in while on stage, and once she is off stage, she enjoys herself as she moans in pleasure not being able to hold it in anymore..
