A Sassy Big-breasted Sister Who Came Home Soaking Wet In A Guerrilla Downpour Is Locked Up And Raped By Konatsu Kashiwagi!

My little sister "Konatsu" has a bad personality, is cheeky, and pisses me off. She always looks down on me, her older brother. It also pisses me off that she has a pretty face and a plump F-cup big tits. Over the past year or so, her body has been growing more and more, and I've been wanting to fuck her all along... Then one day, "Konatsu" got caught in a guerrilla downpour and came home soaking wet, with her see-through bra state... I reached my limit of stress and pent-up horniness, and before I knew it, I was restraining, imprisoning, and raping her... #ChinP
