[M4A] Cousin sister – I’ve always known what you are under that perfect act. Time you admitted it.

I’m the older cousin. The one the family already writes off as the problem. You’re the good one. The polite, soft-spoken cousin sister everyone praises. The one who smiles at dinner and pretends you’ve never had a single dirty thought in your life I’ve watched you for years. The way you look when you think no one notices. The way you freeze when I stand too close. The way your voice changes when I call you out in private. You’re not innocent. You’re just careful.That ends now.

I want a long-term, dark, dominant/submissive RP where I am your cousin brother and I own the dynamic completely. You still have to sit at family dinners, still have to smile for the relatives, still have to pretend nothing is wrong… while knowing exactly what I do to you the second the door closes.

I will degrade you. I will humiliate you. I will slut-shame you for every secret wet thought you’ve ever had about me. I’ll remind you that you’re supposed to be the good girl, the proper cousin, the one above this — and then I’ll use that against you until you’re dripping and shaking and too ashamed to look me in the eye.

You will write as the cousin sister (first person preferred). Soft, hesitant, ashamed, but too far gone to stop. I want the internal conflict the part of you that still wants to be “good” fighting the part that gets wet every time I call you a dirty little family secret.

DM me replying as her. Start after a family gathering. Everyone else has gone to bed. You’re still in the guest room hallway. I’m waiting.

Show me how the good cousin sister breaks.
