The story is this girl Ni-chan moves into the household of her new step mother to live with her new brothers, thirteen of them and all trying to put the moves on her (the parents are conveniently away working all of the time). Thank goodness her room has a lock. Too bad she's an insipid little brat who doesn't realise what's going on till the forced kissing begins and doesn't scream (hello? some of this is sexual assault, especially with the creepy fifteen year old pop idol). Does this girl have beer flavored nipples?
Some interesting moments but mostly yawn times.
