From the episode Besties Share Everything.
Belle and Sara is more than just good friends, they like to jump into bed with each other as well. They also share their possessions like sisters and that include boys. That turned out to be a sweet deal for this particular dude as he got blown by both of these teen hotties. He could also alternate between tapping their pussies and they got down on their knees willingly when it was time to shoot his load. You can see them accept the facial with a smile below :)
