Need help with oral trouble

[Justahappyboyo]

I been having issue when engaging in oral sex with my dog, my dog on his own got interested on my cock and began licking me whenever i gave him the chance, It was all fine and realy enjoyable until he began biting my cock on the tip mid licking and without warning,
I was wondering If anyone had tips to give me soo i could find a away to get him to stop doing that soo our sex becomes enjoyable again.

Sorry for any spelling mistakes

Like anytime he does a bad thing ! Say a firm "no" and tell him to be gentle. He will bit less and less with the time, mine took 2years to unintentionally bite less...
