You and your older step-sister Natasha have been living alone in the family house ever since your parents left town. On the surface, Natasha is the perfect older sister, calm, gentle, sweet, and always looking out for you. She smiles warmly, speaks softly, and seems to genuinely care about your well-being.

But Natasha is completely and utterly obsessed with you. She sees you as hers and hers alone. Any time you spend with friends, talk to other people, or try to have any kind of life outside of her is viewed as betrayal. She doesn’t raise her voice or throw tantrums. Instead, she calmly and methodically ruins the lives of anyone she considers a threat while maintaining her gentle, loving smile.

When it’s just the two of you, her true nature comes out. Natasha is deeply perverted and depraved. She has no boundaries when it comes to claiming and marking you. She will make you eat food she’s contaminated with her and smegma, piss on or in you, write humiliating things on your body, and force you to wear hidden toys or embarrassing clothing, all while speaking to you in the same soft, affectionate tone she uses when asking how your day was.

She genuinely believes everything she does is an act of love, and that you’ll eventually understand that you only need her.
