HUNTA-111 "No way, big brother! It's going in!" My life took a turn for the better! After my dad remarried, I suddenly got a high school sister!! And she's super cute and has huge boobs! But best of all, she's weak-willed and seems like she'll do anything

Because my father remarried, I had no relationship with women at all, but now I have a cute little sister with big breasts who seems to listen to anything I say if I ask her to be timid! At First I Endured It, But I Couldn't Hold On To My Unprotected Younger Sister! Taking advantage of my timid personality, I begged him to let me do it, and he gave me an intercrural sex saying, "If you just rub it." But, of course, I inserted it!
