That was funny. I laughed a good deal. It's a hentai comedy.

Our hero is Motoki, a long-suffering schoolboy who wants to be allowed to do his homework and have a quiet life. His sister Megumi's noisy lesbian love life? It's annoying. Motoki wishes they'd shut up, or for preference leave the house and stop interfering with his studies. "Every day, they're like that. Help me, I can't take it any more!"

When Megumi's girlfriend invades his room, Motoki yells at her. "This is Eika. She's my sister's girlfriend and the main culprit in messing up my daily life."

Eika assumes Motoki's gay because of his best friend, Yuuji, who has a comedy crush on him and is introduced on top of a rock at sea, screaming that "MOTOKI IS MINE!!!!" As far as Yuuji's concerned, the idea of a heterosexual Motoki is unthinkable, illegal and not even worth acknowledging. When Motoki tries to explain that he's straight nonetheless, I laughed at Eika's "oh, really?" She then fellates Motoki, sticks a vibrator up his arse and has vigorous sex with him until Yuuji can arrive and catch them together.

The scene then gets even sillier, with Megumi marching in naked to yell at everyone for being noisy while she's trying to sleep, followed by the arrival of Yuuji's bonkers sister Emi. "It is my pleasure to accept," says Emi, unbothered by Motoki and Eika having X-rated activities while Megumi streaks and Yuuji tries to protect his beloved from all these terrible, terrible females. On being asked why she's here, she says, "Eika invited me for a threesome, but it looks more like a fivesome."

"She looks quiet but she's actually crazy," is Motoki's verdict. Could have been any of them. Nutcases chase each other around his bedroom (and tread on his head) while he declares that he's the unluckiest boy in the world.

That's the episode's first half. The second half involves Motoki's classmate and tutor, Natsuki. He thinks she's an angel because she always keeps her clothes on and never starts screaming at anyone. A chance to study. Peace and quiet. Lovely. Natsuki would be his dream sister and he sees her house as an oasis. Unfortunately, the other three girls are stalking him. Well, it was either that or visit their favourite store for its 40% off dildo sale! A tough choice. "Eika, I didn't know you could lipread!" says Emi while they're halfway up a lamp post.

"I have many talents... What's this?" says Eika, using goggles to watch Motoki and Natsuki though a window. "'Compared to you, my real sister is violent and rude'."

Megumi objects to being called "violent" and electrocutes her friends.

It's silly as hell, obviously. At one point, it breaks the fourth wall. ("Why am I suddenly captured? What happened to our action scene?" "No one wants to see that kind of ordinary action in an erotic comedy!") To poor Motoki's horror, Natsuki turns out to be a predatory bondage queen without even minimal interest in consent. Hentai scenes again! Can't a boy catch a break? Answer: no, although the girls are open-minded about it.

"Promise us you won't molest Motoki without telling us. Then we'll let you have an orgasm."

"All right, I promise!" agrees Natsuki.

I love the idea of a hentai character who's horrified by hentai and just wants a quiet life. This single-episode gag story is throwaway nonsense, but it's also very good.
