what is "solo queen"? today i found an abandoned little ad card outside my door. both sides of it have girls wearing only underwear. seeing phone numbers on it i knew it was not underwear tag. at first i thought it was some kind of illegal (or legal?) porn service, but i saw the words "only delivery solo queens" so i Googled but there was no useful results. any ideas what that is? i'm not gonna call the number. thanks.
