CAWD-539 Deceiving the sister from the same father but different mother

It's been two years since I became a "sex tool" for my closed brother. The other day, after being caught sucking a cock full of unbathed cock, she ejaculated on her face. Yesterday, my nipples and pussy were licked until I drooled. Today... "I don't like it, stop it." The piston of the brother who didn't want to feel it. "I don't want to anymore... Uh..." I want to run away. But I can't escape Because he's family.
