Zorrita eats her brother's cock if she doesn't tell her parents

Sibling sex is becoming more common with some zorritas. This piece of slut eats his brother's cock several times because he likes to enjoy having a good dick stuck to his throat. He tells him that all he has to promise is that he won't tell his parents, because they could be in a lot of trouble if they found out. The brother says yes, that he will not tell her, but in return she has to get screwed, so he puts her cock and fucks her sack to end up running in her pussy.
