Lesbian Human Toilet
A sweetly perverted lesbian, girl or woman who offers HER mouth, lips, throat and stomach to other lesbians, girls or women for use as an actual toilet. Activities include spitting, pissing and sometimes even shitting (and vomiting) into the toilet girl's mouth. 

Sometimes a mouth/jaw vice is applied to force the toilet girl's mouth open for extended periods of time. Usually when she is consuming the excretions of 2 or more lesbians.

Many Hollywood actresses and female musicians use hot lesbian groupies as Lesbian Human Toilets.

Did you hear the hot-gossip rumor that Paris Hilton regularly requires her lezbo groupies to be a "Lesbian Human Toilet" before Paris will grant them girl-sex with her?
