MOST BLATANT CONFESSION !!! How severely will he punish me for this?

OMG!!! I think I really messed up. That wasn't at all nice and good of me. And because I now have a guilty conscience, I'm going to tell him everything. The scalding truth!!! After all, I'm always honest with him. Fuck, I'm a bit excited though. No, excited is not an expression at all: I'm really nervous!!! As the ultimate proof, I even switched on the camera to record everything!!! Phew, what's the best way to start? My hands are already sweating with nervousness. I call him in and tell him everything!!! But his reaction is worse than expected!!! How hard will he punish me now? Can he ever forgive me?
