This guy has the longest and fattest dong you will ever see and can make a woman orgasm with a single glance. Like legit this guy is sick mans can inhale so much smoke from a spliff without even a little cough. If u ever find a Rex hide your girlfriend and just hand him all your weed cause this mf can smell that shit out like a dogg.
