M35, wife left me with morning wood

M35, wife left me with morning wood and I can't go to work like this.

I woke up throbbing today which is pretty normal. When my wife saw it, she joked "is that for me?" before she got up and started getting ready to hang with her girl friends for brunch. I thought maybe she'd come back to it, but nope she just left and I'm still rock hard. So no, this throbbing cock is not for you anymore dear, I'm now stroking to redditors. She views watching any porn as cheating, so it feels kinda wrong but oh so good at the same time. I know I should stop before I take it too far and actually cum for someone else. But my cock won't go down otherwise, I don't know what to do.
