gumhole
A womans sphincter after a long relaxing licking and gentle sucking. Once she is totally relaxed, you can bury your tongue in there and eventually your rock hard cock.
After the concert, we went to a motel. We had some drinks and relaxed. I was getting hard so she started sucking me. I spread her ass cheeks and sniffed and sucked her browneye. It was funky and delicious. After a long session of tonguing her, her gumhole softened up and I buried my tongue deeply in her dumper. After a few orgasms she let me bury my rock hard cock in her ass and orgasmically explode deep in her dumper.
