That her own brother’s pussy penetrates her is not something that makes this slut any grace, but she is between the sword and the wall because she desperately needs your help. The brother is very bastard and asks at the beginning for a straw that ends up turning in a blowjob and in a full blow.
She knows that her little sister is desperate and that she would do anything to do the favor she has asked for, so she goes through her pussy and destroys her. When she has already fucked her well, she releases a good corridon on top of the tits.
