What a mostly unfabulous hentai we have here.
I cannot fathom why anyone would think rape is necessary or sexy, but hey, what do I know?
The story follows two sisters who are blackmailed into screwing this hideous, hairy, fat old man with an Impressive Moustache because he can put them into debt or something or the other. I didn't pay any attention to the story because it was just stupid. It was probably interesting because maybe things like this do happen, but the delivery was plain old bad.
The art wasn't as bad as it could have been, but it wasn't good either. And
the sound was bleh--it sounded dated or like something I would hear in a porno with acting in it or a Lifetime movie or something.
The characters were just there. They had no personality and all they did was get raped or have sex with one another. There's sister x sister lovin', mother x daughter lovin', young guy x older woman lovin', older woman x younger girl lovin'...and on and on.
Unfortunately for SOME of you (but fabulously for me) there was a significant lack of tentacle rape and demon rape and pigs in thongs rape, so if you get your kicks off of bestiality, then you will be sorely disappointed.
While there are a few scenes you could probably fap to, the old man rape totally killed any sexiness that was there.
I would say to watch it just for the lesbian sex scenes--they're actually pretty hot. But other than that, don't rush to drop your drawers for Ai Shimai ~Futari no Kajitsu~ or as I have seen it dubbed 'Immoral Sisters'.
