HUNTA-775 I was too obsessed with my immature sister's body, so I forced myself inside her and now she's mine! Living together in a cramped one-room apartment with my super defenseless sister whose body is still developing...!?

Still in the midst of development, my defenseless little sister and I are living together in a cramped one-room apartment. Her breasts and ass are so defenseless that I'm constantly hard! My sexual desires are building up to the point of no return! Before I knew it, I was assaulting my sister, forcibly penetrating her and ejaculating inside! I've done something irreparable… Big trouble! But then, my sister, who can't forget the pleasure of being inseminated, has been blatantly seeking out my dick and hinting at sex ever since. I can't help but get turned on and end up inseminating her multiple times, becoming completely obsessed with my sister!!
