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 parent's remarriage gave me a step-sister while I was a college student. 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 wears panty shots and exposes herself a lot, and it seems like she doesn't know anything about sex yet... Thanks to my seniority, I'm a little older and cunning, so I trick Mitsuha into using pleasure control to make her my sex doll! “Damn brother, is it really okay for brother and sister to do this?” “Mitsuha, sex is amazing!”
