Training for Shirayuri and the others continues today in preparation for the swapping party at the graduation ceremony. "What do you want to do with me?" Student council president Mai teaches the ideal tongue technique to an underclassman who confessed to her... "Wow... you're so wet..." Student council secretary Maki hides a vibrator in the underclassman's panties and plays with her... On the last day of their visit, a swapping party covered in love juice unfolds, and the obscene tradition is passed down!
