Kenkou Zenrakei Suiei-bu Umishou EP10 - Breast Massage?

It's time for the Ono Island Summer Festival. Amuro and Kaname are enjoying the sights when they are mey by Maaya, who insists that Kaname spend the festival with her instead of Amuro. However, Kaname still has bad recollections of Maaya bullying her as a child. His refusal is interpreted by Maaya as an insult towards her small bust size and she runs off. Kaname and Amuro are then joined by the rest of the female members of the team, while the angry Maaya is met by Makio. Makio confesses to Maaya that she is also concerned about her small bust and that she "would just once like to zip through the wind with her boobs". While she initially dismisses the idea, Maaya becomes intrigued when Makio tells her about a "secret technique" to increase bust size, and the duo retires to the ladies' room. Meanwhile, the rest of the members find Ikamasa manning his father's fishing booth at the festival. While the fish are expensive (Ikamasa's father will cook any fish caught) the games are rigged. That is for everyone except for Amuro. Through a turn of events Kaname finds himself competing against Amuro and her father at a watermelon eating contest. Back at the ladies' room, Maaya and Makio corner Shizuoka on why her bust is so large. We return to the watermelon-eating contest where Kaname is determined to win -- the penalty for losing is a drop into a dunk tank! The episode post-script follows male swim team members Takeda, Tsunime and Jun through the festival on their quest to meet "cute girls". The girls they meet, however, are not who they expected...
