In this Kaitlynn with Suzie scene, Suzie sucks Buck's cock back and forth from Kaitlynn's ass! It was Suzie's birthday present from Buck and Kaitlynn. Kaitlynn and Suzie did a couple scenes together
This is ass to the other girls mouth or Kaitlynn ATOGM with Suzie and, of course, this simply means Suzie was there to suck Kaitlynn's ass juices off Bucks cock a dozen or more times. Ass to other girls mouth is common now but these girls are amateurs and they don't know to clean themselves before the shoot. This means it's dirty ass to other girls mouth.
