SCPX-298 — My Sister Is So Serious That She Blushes When I Say Dirty Jokes. Even Though She's Beautiful, She Doesn't Seem To Have A Boyfriend, So I Tease Her And Say, "You're A Virgin, Aren't You?" And It Turns Out She's A Real Virgin! When I Ask Her, "Do You Have A Crush On Anyone?", I'm Surprised It's Me! I'm A Brocon!

My sister is a neat and serious girl that I'm proud of. When I tease her about her complete lack of interest in men, she gets shy and angry, which shows that she's still a virgin!? The person she likes is actually me!? When I gently teach my innocent sister how to have sex, she's surprisingly sensitive and my little brother's dick gets fully erect! I repeatedly cum inside my sister, who desperately tries to keep her voice down so our parents don't hear!
