No deep plot, simple stuff. Just like what you’d expect from a hentai involving shota and a milf. Your aunt is sexually frustrated since their husband (your uncle) puts his work above her. And is not a raging coomer. The MC on the other hand has a raging boner for mommies. Ever since the MC was taken in by the two, she’s been wanting to have a child of her own. To a degree the aunt lives out her fantasy with the MC, which provides the reason for her cheating behavior. Up until the endgame, where it comes true for story purposes (although you could at any time during dangerous days). 
The aunt doesn’t go further than your archetypal anime milf. Overly sweet, overly kind, and desperate for sticky white goo. Being in a consensual netorare between her nephew, the MC. Thus its your job to cuck your uncle. 

The 4 main H scenes occur as your stage reward. Though there are other H scenes that occur as a result of being in a certain stage and doing specific actions. The criteria scales with each stage completed and there are hints on how to escalate the relationship. The only problem is that it will get boring. Then again there’s not much else to do in the game but grind it out. You’ll be able to finish in a few hours or so. Unless you just use the full save just to see what is in store.

Gameplay is a more advanced visual novel. You choose what to do with the character and the presentation is in the style of a visual novel. There are a lot of choices, but not much variation to them. In actuality, you might just be doing two things over and over with the occasional different choice. 
All you really need to do is the chores, study, and occasionally choose one of the extra H scenes (bath, beg (when available), and going to bed early). Stamina doesn’t matter, since you’ll recover a bit every day and by choices like bathing or sharing a drink. In any case you have about 4-5 choices you can make.

Yes you can have your aunt wear different outfits. They do change the H scene when she wears them. The positions still stay the same. That’s most likely where you’ll put most of the in-game currency.

There is no voice acting, just moaning and other lewd noises. But what’s worthy of talking about is the fapping noises.
The fapping is so similar to someone slapping their thigh. It has the same kind of abrasiveness. I’m not kidding, go listen for yourself. Speed up H scenes to get a machine gun.

Dialogue most of the time ranges from lovey-dovey to just SEX. Like imagine the lewdest thing you could say to someone and that’s most of the dialogue during H-scenes.

By far the worst part is the artwork. Don’t get me wrong, it communicates what it needs to get you erect. That might be all you need. But it just doesn’t look great compared to artwork in other H-games. But you can give some forgiveness, it’s a single dev and most likely an absolute beginner artist.

Though not a bad game, at worst just boring. But do play if you’re in the mood for big titty anime mommies. With the full save probably.
