Ha, now here we have a fabulously unfabulous hentai right here.
F-Force is one of my favourite hentai out there right now since it's just so bad. I don't think I laughed so much before.
The story follows a young man and a group of women who follow him around, occasionally to each have sex with him/get raped/have sex with one another. There are some Pillars of Light which the demons have created that would destroy their land, and it is their duty to stop the demons.
So, the Super Sentai--I mean, Power Rangers--uh, F-Force go around and use their super powers to save mankind.
And have lots of sex.
The art was a a bummer, since it wasn't as good as it should have been. There were some interesting character design and settings, but it wasn't as crisp and detailed as it could have been. The sound wasn't that great, either.
Now, here's where I liked it--the characters. Each one of them, believe it or not, has a personality. Mostly that personality is determined by their clothes...
I think F-Force was also one of the few hentai where there was actual consensual sex as well. And there's a smattering of lesbian sex, so for those who like that, there you go. Unfortunately, there was so much demon rape that I was turned off. Literally. Zipped my jeans back up and everything.
You should watch this, it's pretty decent.
