Ojou won free tickets at a raffle the previous episode, so the girls are going to a water park. Fun and fan-service to be had in the sun! But this excursion led to puzzling questions.
- Is it true that really big boobs float in water? It's true!
- If you use a tampon in the pool, won't it absorb water and expand inside? Otako, the Tampon Professor, explains that the vejay-jay naturally tightens up in water and the tampon string is waterproof so it won't absorb water, so no.
Galko has glisteningly smooth armpits but forgot to shave her pubes for her bikini excursion, but Otako provides a disposable razor. That's just not good enough. Proper pube shaving should be done by a professional or a snatch-shaving servant and with scented shaving leather and strap straight razors. Galko then befriends a young boy who ditched his Mom after some catty grade school girls teased him but then he lost his wallet. So when you see some mean girls tormenting a boy, smush his face into your enormous breasts to drive the girls away. Unfortunately, Galko got sunburned because she used what she thought was her sister's spray-on sunscreen but it was a pheromone spray. The diminutive Otako got sprayed with it and was hit on by grade school boys.
- Is it true that your boobs grow bigger if you drink milk? An unanswered mystery at the end of the episode.

how annoying! i though some complain in that first comment only to be a COMPLETE spoiler.
