CAWD-539 Cheating on his half-sister

It's been two years since I became a "sex tool" for my closeted brother. The other day, after being forced to suck a cock covered in unwashed cock, she ejaculated on her face. Yesterday, my nipples and pussy were licked until I was drooling. Today... "If you don't like it, stop it." Who Doesn't Want To Feel His Piston Wheel? "I don't want anymore... Uh..." I wanted to run away. But I can't escape Because he's family.
