Get the Rupert Brainmug. Rupert is a man who LOVES dogs. Sometimes he slips it in just to see what it feels like. The dogs don't enjoy it though, they prefer when Rupert is the one who is getting penetrated. When Rupert is not blasting his dogs anus he takes up hobbies in watching dog porn. He performs this live on his social media every Thursday for all his fellow dog fanatics to see.
