FPRE-034 I tricked my rebellious big-breasted sister, whose body has grown into an adult, into raw creampie! ~I punish her by controlling her pleasure by taking advantage of her lack of sexual knowledge~ Mitsuha Nonose

My parents remarried and I, a college student, got a step-sister. Mitsuha, a J-type girl, is in her rebellious phase and seems to hate me. She's cheeky and annoying, but her body is feminine with plump big breasts. However, this younger sister seems to have no knowledge of sex yet, as she wears panty shots and exposes herself a lot. Thanks to my seniority, I'm a little older and cunning, so I tricked Mitsuha into using my pleasure control to have sex with her.
