Okay i came across this scene and found a link that has screen shots from it, its a scene with marc davis and taylor "all 45 of me" rain. In the scene she takes it up the ass then he blows a load in her mouth (keeping in mind im not a big taylor or anal fan, call me a quarter pounder with cheese if you must), pretty straight forward, but then marc gets down low , tilts his head and opens his mouth, by now i know whats coming next but hold hope that im horribly wrong, unfortunately i wasn't, taylor then leans over his open mouth and spits the cum back in. Now one of the benefits of being a straight man is that you don't have to taste cum, have it shot on your face or into your mouth. All rainbow kisses, and any form of cum swaping in porn needs to stop before it gets the chance to catch on, unless its a scene that involves max hardcore getting his own piss spat back in his face, i would like to see that, i have added a link with a photo of this disgusting act, in the bottom right.
