ass blos·som as blos-uhm-n. a burgeoning rectal sphincter. The purtruding rosey inards of a chick that got ass fucked really hard. Sometimes a result of fisting or large object insertion.
...and then Mike fucked her ass right after Joey; she just laid there moaning with her ass blossom all stickin' out n' shit!
