Door 12 - Getting the best boyfriend to wank off

I barely make it in time for the video call with my best mate. We've known each other for a really long time but nothing would have worked out! Unfortunately, he's also a boring, loyal soul and firmly convinced that he wouldn't even get it up with someone else than his long-term girlfriend. I've been teasing him about it for a long time, but today I really want to know. Do you think he has a chance? And what if I suddenly have the most power over him...
