After many years of sexual adventures, Mimei has managed to collect a large number of "penis prints". Now she is going to get married, but first she wants to reach the magical number of 100 penis prints, as this is her last chance.
Luckily, this movie has more to offer than the bland title which would have been more appropriate on a modern American porno (although it would've thrown in a pun somewhere). The title somehow lowered my expectations enough for the movie to actually entertain me. A little bit, at least. It's far from as entertaining as "Zoom In: Sex Apartments", but still maintains an easy, fun style that makes it 66 minutes of decent entertainment. If you're in the mood for Nikkatsu, that is.
The story, which you would've expected being about an anal-obsessed woman, is about a woman's struggle to sleep with 100 men before her marriage. Or rather, to get a collection of 100 "penis prints". A penis print is when you paint the penis and then push it against a paper, leaving a nice, black penis splotch. Mimei is our woman, and she's picking up men off of the streets. It's going pretty damn good up until her very last man. This is a man who has control trained his penis that he can basically only orgasm if he decides to. Him and Mimei make a pact - she can only get her print if she can make him cum within 55-or-so hours. Most of these 55 hours are, in fact, spent fucking. The side plot, which might be part of the reason for the name (although illogical naming it after the side plot), is about Mimei's lesbian friends who are so sick of men that they go around tying men up and pushing dildo's in their asses. Classy, ladies!
So what makes it entertaining, you ask? It's mostly just sex on top of sex with sex filling, like all Nikkatsu movies. The movie is in fact really stupid, and that mixed with "just enough" of a plotline, makes it entertaining. We don't care if she will get her prints or not, we don't care why the lesbians go on their anti-man adventure, we don't even care that (SPOILER ALERT!) she loses all the prints in the last minute, rendering the entire movie pointless. I mean, that last part was kinda humorous, and the final "twist" isn't too bad either. It's not too far from an American comedy, except where this one ends is where the American movie would begin - forcing it into a moral story of "make-everything-right"! This movie knows which part of that story we most want to see, and leaves the story not giving a fuck about morality or doing the right thing. It's a sexploitation comedy from Japan, what do you expect?
The sex won't arouse you since it's the standard censored stuff - either blurred, pixelated or hidden behind objects. This is Japan, after all. Does it matter? No, because the actors are so silly that it won't be good spanking material anyway. And that's how we like it! Completely forced sex that arouses no one, leaving us seeking pleasure in other parts of the movie. Such as the poor story or the ridiculous situation they get themselves in (55h sex marathon!). "I Love It From Behind!" isn't something I would recommend, but if you know the genre and find it funny then this isn't the worst one. It works, for another 60-ish minute sexploitation flick.
