I'll have a go.

For the small segment of the population who are unnaturally squeamish about sexual intimacy, watching an attractive, semi-literate middle-class white girl get repeatedly sodomized by Brazillian trannies who deposit loads in her ass (followed by her shitting it into a martini glass and drinking it) is a way to demystify the sexual acts and make normal (normal?) sexual activity seem less obscene.

In the alternative, by masturbating furiously to gag-factor and Max Hardcore movies, my desire to forcibly sodomize "Lisa", the neighbour down the hall, abates temporarily, thus allowing me to again become a loving husband, father and contributing member of society (at least until Lisa where's that top I like again )

Have a good weekend everyone!
