You enter my room to blackmail me: you know my kinky secret and you want to tell everyone, unless I become your slave! I'm reluctant because you're my brother, but I accept to follow your orders! You make me undress and write humiliating words on my body, you want me to be your submissive pet slut! You order me to behave like a dog, you make your sister bark, use a bowl and pee like a dog! As a final humiliation you order me to squirt on my own face fingering my pussy, turning me into a wet slave covered in squirt!
