My proud, clear-headed and serious older sister. She gets embarrassed and angry when teased for having no masculinity at all, could she be a virgin!? Could the person she likes be me!? I gently teach her how to be H with her innocent older sister, and she's surprisingly sensitive, making my little brother's ● fully erect! I commit incestuous sex several times with my sister, who desperately tries to stifle her voice so our parents can't hear!
