Gakuen de Jikan yo Tomare(2015)

学園で時間よ止まれ

The bastard son of a rich aristocrat is hellbent on seeking revenge ever since his father abandoned him and his mother. He decides to teach his father a lesson by destroying what he treasures the most, his two daughters. He infiltrates their prestigious school with a magical time-freezing device he received from a witch — and proceeds to repeatedly rape his half-sisters, leaving them confused, helpless, and begging for mercy.
