My bf wants me to poop on him

Holy moly, where do I start. My bf approached me today with a wild proposition. He said it’s been his lifelong dream for me to drop a hot load on his chest. That is quote for quote what he said! I’m speechless, and scared tbh. I obviously said no and he started pouting saying I don’t love him. Ladies what do I do? I don’t want to leave him, but this is crazy! Should I pay someone else to do it?
