**very taboo brother/sister roleplay**
Every full moon, brother turns into a beast. And the family ritual must be complete. His desires to breed must be satiated, or he gets out of control.
This is my first time completing the mating ritual with my brother. He's chained, and has a hungry look in his eyes. I have to offer my scented panties to him first, to ignite his hormones and have him ready to breed. And after that.... I'm his to play with.
I have to remember.... this isn't really my brother. He's sick with a curse. My brother would never actually want to inseminate his own sister.... But tonight, I must make him happy. No matter how many times he wants to use my pussy.
