My super serious and kind older sister failed her exams and ended up in a slutty girls' school, turning into a super slutty gal! Naturally, all of my sister's friends are also sluts, so they come to play in the room I share with my sister and make unexpected sexual advances from the top bunk! They flash their panties non-stop from above, making me get an erection. Of course, once I'm erect, I get easily attacked and devoured! And it's not just her slutty friends; even my sister attacks me…
