“Likewise if the pain of me punishing your balls has made you lose your erection then you have 60 seconds to get it rock hard for me again or else you can get out of here. I need a man who can not only take a little pain, but who actually gets off on it!”
“If you’re still here, then I have 20 more expertly-placed kicks for you!”
