I have seen quite a number of animes out there, and I know the animators were doing all they could to get those jugs on those gals to go free. Demon King Diamo, Heaven's Lost Property, Needless. All of them are full of fan service scenes.
And it is wonderful! xd
So go watch them all. They are full of fun and perverted jokes.
Things like flying panties that two episodes later become pantie bombs, or porno magazines that come alive and hold a parade.
