Childhood friends, Rouma and Tamaki, are not just friends. Actually, they have sexual intercourse, but they're not lovers, either. One day, Tamaki gets angry with Rouma and announces to break with him because he didn't take contraception measure while they were doing things.
However, because they belong to the same club, they have to meet. Seeing their cold attitudes, Yuuri tries to make them friends again. However, she can't hide her love toward Rouma, and confesses her love. Then, they make love, but...
The male lead, Oria Ryoma, is a lazy lecherous pervert without an objective in his life and the IQ of an insect. He does however have one redeeming quality - he's a strong kick-boxer and knows how to protect women. As such, all the girls around him constantly feel the urge to jump on his manhood and suffocate him with their breasts. Not the most romantic of stories is it? Not at all, but such is the case with most hentai.
The female cast is not worth mentioning at all. At times I was under the impression that the male lead was having sex with inflatable dolls rather than something that resembles characters. Moreover, everything is made extremely convenient because the girls apparently have no conscience and are absolutely fine with Oria banging everything in sight as long as they get their turn.
Moving on to the art, it was well drawn and the style comparable to most of the overwhelmingly average hentai series. Likewise voice acting was decent however the constant low-bass run-of-the-mill porn music can easily get on your nerves after a while. If anything, I wish they would stop putting the same annoying melody in, you know which one it is I'm talking about, if you've seen your share of hentai you would have heard it about a million times by now.
Overall, the story was far fetched, unrealistic and cheesy. The sex scenes themselves were somewhat satisfactory. Taking all things into account this series is average at best. Watchable without smashing your head against the keyboard but not something I'd personally recommend. If you're looking only for well drawn hanky-panky scenes then yes, if you want a decent story to go with it then no.
