On the eve of their graduation at Big Boob Finishing School, Sophie Mae expresses self-doubts when Arianna Sinn comes by to see her. Sophie reads an excerpt from Michelle Bond's manual, "The Ultimate Guide To Pleasing Men" about how to properly please a cock. Arianna offers to help. Together they will use a banana as a learning tool. Arianna licks and places the banana between her big boobs and has Sophie do the same. This erotic play and cock instruction turns them on and they take turns kissing and licking each others' large, beautifully shaped naturals. Their make-out session ends and all of the girls meet with Michelle for a final quiz. Michelle has the pleasure of announcing that their graduation will follow after this meeting. The girls assemble in their pasteboard graduation caps and meet on the estate for their final moments as a unique group. They will always remember their special week together at Big Boob Finishing School in Portugal.
