Bakunyuu Bomb aka Exploding Tits BOMB. Its a series of 3 episodes involving women with really big tits who dont wear bras. Story: the 3 stories are independent. The first one with the nurse is funny and the best out of all 3. But with many hentai they ruin it with rape: The second episode involves rape (its not brutal). And the third episode involves rape and humiliation (not brutal). You think after trying rape in the second episode they'd try something different for ep3. Ep 3 is so full of hentai clichés we've seen before, very predictableCharacters:
A nurse, a house wife, a teacher. They are likable characters. With adorable faces.

Animation:
First of all its censored. But the animation style is good. Folks may complain about the freakishly large boobs but the theme of the hentai is large breast, it says so in the title.
But the women's vagina is really well drawn and is very hot and arousing the way they are drawn. The sex scenes are hot.

Its a good hentai. Would have been better without the rape.
