...... Well its not bad but not really that good either.
I actually had fun during the first playthrough
During my first playthrough I tried playing as the 'nice' guy. I got seduced my the step-mother. I remember when the character first catches her masturbating. I was yelling at the screen "No! Bad! Abort! Get out of there" and when the character looks at his sisters bottom I was going "No, look here" points mouse at face "Not here" points mouse at bottom. But they never listened to me, they never do. I wonder if you can get a threesome with Hitomi and Yuki
After playing though his the second time I thought I wonder what it would be like if I was the main character.
I would be trying to avoid being seduced by the mother and accendentily upsetting a sister that would be anything to make me love her
Then I got a better idea. How about a Hentai game were the main character is some guy that got sucked into a game? Both Final Fantasy Tactics Advance games had some guy coming from the 'normal' world into a different one. Why not make a hentai game that uses the same plot-line? All the guy can remember is that he was playing a hentai game and all the people he is talking to are the characters? Do you try to stay 'pure' in this hentai world? Or do you go "What the hell" and join all the perverseness.
Your character will be pursued by all forms of hentai. Lolicon (Some young girls blush at your character the moment he steps into a primary school), Bestiality (walking though a park, your character notices some noise behind some bushes, when he looks though he finds a woman having sex with a dog) and tentacle rape (Your character hears a news report about reports of a tentacle monster raping women for no reason, however no one cares.... or something like this happens)
Main Character: Did you hear what it said in the news last night about a tentacle monster raping women?
Girl: Oh yes... (starts blushing) I just wish that it would rape me.(perverted face) I get so wet thinking about it.
Choice 1: "....."
Choice 2: "Call me when the monster decides to rape you"
Hey if any hentai company is listening. MAKE THIS GAME!
