There's something really hot about buff or twink porn stars who start their careers in successful mainstream safe sex porn as versatile tops then "cross over" to the Dark side and get downright filthy as bottoms. Here are some of examples:
Carlos Morales: ff, bb, piss, cum eating
Jeff Palmer: bb, piss, cum eating
Drew Peters: ff, bb, scat
Jackson Price: ff, bb, cum eating
Josh Weston: ff, bb
Mason Wyler: bb, piss
Sean Storm: bb
Joey Milano: bb
Brian Mark: bb, piss, scat
Allan Gregory: ff, bb, cum eating
And some other versatile (so far non-bb) dirty whores:
Eric Rhodes: ff, piss, cum eater
Francesco Dimacho: piss, cum eater
Francois Sagat: piss
Any others to add to the list?
