Not to rain on your hate-parade, Mori, but that "filthy american pig artist" is Japanese. Everywhere I've seen him post anything, it's either in japanese or in such broken english that there's no way it's his native language.
I could never participate in something like this. If a woman is going to drink a mug with my semen inside it, that mug better be all of my semen or none of my semen at all. ======= UPDATE :: The only possible (emphasis on possible) exception I would make is if the other guys are very, very close friends of mine and they each also have a sexy, beautiful lady whom I want to guzzle my gravy.
I would be like, "You want my lady to swallow your jism, you best believe your lady is gonna swallow mine!"
