Sierra is a bit compulsive. Give her a task to start, and she will not give up until everything is complete.
This makes her an exceptional blowjob artist, insuring every last inch of your cock is licked, sucked, and spit on. That‘s only half of what needs to be done though, the other half is her utilizing her tongue in new and unique ways to ensure you a load of mass proportions.
This girl doesn‘t spit either, expect no cleanup with her all star swallowing skills too!
