On their way home, three amateur baseball players pass by a new 'massage parlour' offering very reasonable rates. Two of the friends talk the third, who is due to be married, into paying the place a visit. What the trio don't realise is that the girls are under orders to chop off their customers' cocks! A completely insane slice of sexy comedy/horror from Japan, Horny House of Horror is a whole lot of fun if you like your entertainment demented, trashy and very bloody from start to finish.
After the guys are allowed to inspect the girls' butts to ensure quality, customer number one is taken into a room where prostitute Nonoko (Asami) emasculates the poor guy with a mechanical toothed device attached to her pussy. A few gallons of blood are sprayed all over.
Client number two is shackled and forced to watch an erotic dance by hooker Kaori, but is told by the katana wielding manager that he will have his member sliced off should he get an erection. Cue even more gallons of blood.
The final guy, the one who entered the place under duress, gets Nagisa, played by sexy Saori Hara, who doesn't enjoy her work as much as the other two girls, and finally admits to her intended victim that the place is a Sex Parlor from Hell where the customers must die. The pair decide to flee, but with the building loaded with hidden cameras, escape isn't going to be easy.
At only 75 minutes long, Horny House of Horror never outstays its welcome, and packs an awful lot of deranged nonsense into its short running time, including acid sex lube, fart gags, eyeballs splatting against the screen, a graphic disembowelment, a Bond-style villain named Shitaragi (I shitaragi you not!) and a severed schlong in an ash-tray (with the tip optically fogged out, as are any of the AV starlets naughty bits).
