This is one of the most vile and illegal sex moves that can be performed. First you need a very unintelligent girl that trust you and you can have sex with, then you cook her coos coos with saw dust in it so she gets very constipated, then after a week, start having sex with her put two large sewer rats on her back in a cage that is opened on one side to the girls back, then put napalm on the rats, light them on fire forcing them to scratch into the girl. This will cause a vibrating sensation that is very pleasureable for the man.
