Why does a chick play cards if she loses her mouth every time and gives a blowjob

A babe with a luscious ass loves to play blowjob cards with her brother, for the bitch knows that she will lose and will suck cock. The brunette purposely makes the guy win and reaches for his cock. The blowjob starts with a light licking of the head and fondling of the testicles, and then the hard fir climbs almost into the throat. Sis gets high on incest and even asks her favorite brother to fill her mouth with cum so she can swallow the protein.
