Overall a pretty great game and a decent NTR game. Has some very good mechanics for NTR as you can see what the heroine is doing everyday and there's a pretty large variety of pictures so it never gets old. Its around 1 to 4 hours depending on if you rush it or take your time but it certainly has my recommendation. The biggest glaring fault is the 3DCG art which not many will like and I can't really blame anyone for thinking that. Took me a while to get used to it but its actually grown on me and even then, its NTR so I believe most of the enjoyment comes from the story and scenarios. If you enjoyed this game then I recommend the dev's other works, some of which are NTR. The dev has a lot of passion for their games so please give the game a try if it catches your eye.

A quick summary of the game's plot as incentive for those interested in giving the game a shot.
MC and heroine are childhood friends and currently in highschool, furthermore they're dating. The next logical step for them to take is marriage after graduating but there's a problem. The heroine is pretty much the strongest person in town by far and lives in a doho and while she does love the MC, she wants to marry someone stronger than her. The MC himself is no slouch and can hold himself in a fight but he's not interested in martial arts and got rusty over years of neglecting training. The heroine, knowing that the MC is lazy when it comes to martial arts comes up with a plan to get him to train, get stronger, beat her and finally take her hand in marriage. That is, by telling him that she'll fuck other guys until he gets strong enough to marry her, furthermore the MC is also banned from sex with her until he beats her (though he can beg her for some sexual favours). This is pretty much where the story begins. As the MC trains in different styles to get stronger, she fucks other guys and reports it to the MC in an attempt to encourage him.
The game has two routes but that's pretty much just a formality as the game only has one route worth playing. The first route is when the MC trains and beats the heroine in a fight 3 times. After that, he takes her hand in marriage and you get the good ending.
The other route is when the MC takes too long to beat her. The heroine gradually has more radical sex with other guys as the game progresses. She starts off with a virgin at school and she's not really that serious in actually sleeping with other men at this point. After the kid, she sleeps with a teacher, then one of those chara guys who always find their way into NTR games. The more she sleeps with other men, the more she realizes how inexperienced in sex she is and that while she's stronger than most people, she can be easily defeated by sex. Meanwhile, the MC is also gradually getting turned on by her increasingly erotic and concerning NTR reports of what she's been doing behind his back. Eventually, the heroine starts to develop some serious masochistic tendencies and participates in increasingly humiliating acts under various guys. Eventually she'll reach a point of no return and her masochistic tendencies lead her to fully submitting to so random dude she beat in a fight years ago. She fakes getting beat by him in a rematch so that she can see what he'll do to her. The guy ends up turning her into his own sex slave and by this point the MC can no longer challenge her as she now takes pleasure in getting conquered by those weaker than her and the random dude beat the MC to it. After that, she tells the MC that she's been turned into the guy's sex slave and that he's banned from having sex with her forever but she continues to give him NTR reports of what she's doing with her new master. Eventually she even signs her rights away to the dude just so that she can descend further into her fetish. By the end of the game, the MC will have encountered her in her dojo getting gangbanged by a fuckton of dudes and her master pretty much says that her relationship with the MC is now void as she clearly is too busy indulging in her fantasies at this point. The MC doesn't actually leave her though and tells her master that he doesn't mind having this abnormal relationship and that he wants to continue to love her. The master actually allows this and so the game timeskips to the future. The MC and heroine have now been married and they live in the dojo together. She still clearly loves the MC however her master now lives with them as well and she listens to absolutely everything that he says. The MC is likely still banned from sex (or at the very least only allowed to use a condom, I don't remember.) and the heroine by this point is still indulging in her fantasies. The master has pretty much every say in the house and the heroine follows his every command with a smile on her face. The MC on the other hand is actually content with this lifestyle and realizes that just like the heroine, he too has succumbed in the very end. (See what I did there with the title drop?)
