Many decades ago a party hostess would sell Tupperware products, such as cooking utensils and bowls to her friends at Tupperware parties. The women who were invited often dragged their husbands or boyfriends along. The men universally hated this. So now when women throw parties that they don’t want their men to come along they call them Tupperware parties. These parties can consist of all sorts of naughty activities that “good girls” don’t do. This can include everything from drinking, smoking weed, male and/or female strippers, lewd party games and some form of truth or dare. The one constant that defines a true “Tupperware party” is that the women present get partially or fully nude and masturbate together. This may or may not lead to the women having sex together but the defining activity in a a “Tupperware party” is female group masturbation.
