My Beloved Sister's Sudden Marriage... Driven Mad with Anger and Jealousy, I Turned My Sister into My Personal Sex Pet for the Days Leading Up to Her Wedding! Kijima Airi
I thought my sister was truly mine...! After losing their parents, she devoted herself to supporting her reclusive younger brother—kind, caring, and selfless. But between this sister and her incest-obsessed, hyper-sexual virgin brother, a secret physical bond had quietly taken root. When he learns of her engagement, jealousy consumes him and he spirals into depraved obsession. For the days leading up to her wedding, he takes complete, unrestrained possession of the sister he adores. Turning her into his personal sex pet, he jokes cruelly that if she gets pregnant with his baby, she'll have to break off the engagement. Unable to withstand his relentless desires, she screams desperately for him to stop—but he continues, thrusting inside her again and again, flooding her with creampie after creampie.
