ok this is what you do....
go to the girl you've been fuckin... tell her you want some bondage action (hopefull she's into it or this whole plan goes to shit) handcuff her to a bed and put a gag in her mouth... then fuck her, then nut in both her eyes.... leave her there..
go get the other one... cumm in both her eyes while driving back to the house with the other one...put a gag on her as well

tie her up in a corner... go sleep on the couch.. problem solved...
