Blowjob with Teeth

In this sadistic session I show my slave that a blowjob from me is anything but relaxing. I warn him right away, that I have the bad habit of using my teeth. Without showing any mercy, I bite right into the sensitive head of his dick and work his shaft with painful bites. His balls aren't safe from my teeth either. While he whines in pain I just laugh at him and make it clear how pathetic his condition is: He would never receive a real blowjob from me! After his orgasm I collect the load and I spit the cum into his mouth. Since he is especially sensitive after cumming, I just continue to bite into his cock and balls...
