It's called Taimanin Asagi - hottest series I've ever seen. And there are 4 of them... all filled with gigantic cumshots.
Another movie like it is called Kengoku Senkan. By the same director. Even though it has only one volume so far (out of possibly 4 more to be made), it's similar in style.
TONS of cumshots, huge tits and the animation and sound effects are top notch.
