Asswhore could be considered a supreme insult. It refers to somebody that is such a whore, that the term "whore" alone, does not justify the magnitude of their whorishness. Therefore, they may be dubbed "asswhore", as they will take it up the ass from anyone at anytime.
"Man, that chick is such a whore"
"She is beyond that, she's an asswhore"
An ass whore loves getting fucked in her tight little ass. Sometimes she likes it even more than in her wet cunt. She is often married and doesnt care whos cock is pumping her dirty ass. She never says no to a hot hard cock in her ass.
Kathy is a total ass whore. She is 54 now and married but has loved letting men fuck her sexy ass since she was 17 when her uncle started pumping her in her asshole so he wouldnt get her pregnant. She loves the feeling of a hard cock sliding deep in her tight ass as she rubs her clit and begs whoever is fucking her to do her harder.
