Ore no Imouto ga Saikou no Okazudatta

My younger sister walked in on me pleasuring myself while playing a sibling-themed adult game. To my shock, my usually composed sister offered to assist me in the act. Things escalated when she involved my friends and even convinced the school’s most attractive girl to join in. Now I’m left wondering—can I ever have a normal relationship if I’m only turned on by my sister? And why does she keep staring at me while I do it? The whole situation is beyond bizarre, leaving me confused and questioning everything. How did things spiral this far out of control? Her unexpected behavior has turned my life upside down, and I don’t know how to handle it. The more I think about it, the stranger it gets. What’s her real motive behind all this? Is she just messing with me, or is there something deeper going on? One thing’s for sure—nothing will ever be the same again.
