Your enjoyment of this game entirely hinges on how much you like the character designs of the five heroines - if this fails to meet your expectations the rest of the game won't change your mind. So go onto the game's dlsite page, see the standing portraits of all the girls and determine if your dick is ready, and go jump in. But for those who need more convincing..
NTR Lesson is another life-sim management game popularized by NTR Legend except now you're a lecherous fat bastard tutor who got expelled from teaching because he diddled the students. The profile pages for the characters aren't half bad. Unfortunately if you are expecting anything beyond those profiles, such as an elaborate plot, characterization, or writing in general you won't find it here. Dialogue is the bare minimum, there's only one or two major story beats to introduce more heroines and from there it's just small one-two lines that change at the start/end of scenes. But with that said, the gameplay loop here is to farm money and knowledge during the day and tutor your two main pupils at night, doing h-stuff all in between.
The game is boring, and also doesn't respect your time. You will realize this one hour in, when everytime you want to go to a new area, or if time passes, a lengthy animation will fade out the screen into the next, taking about five excruciating seconds. Having to endure these so often is languishing, and you can only speed up the time of day transitions by clicking and holding lmb. It's the primary reason the game sucks to play.
Most of the minigames are pretty boring, most just amount to matching the colour with the coordinating left or right mouse click. There's a game where trivia is offered, which is neat to try and remember, until you realize spamming buttons as fast as possible nets the same amount, so why bother thinking. The molestation gameplay that you usually see in these games can be completed more quickly in comparison, which is good, but the game doesn't bother to try and make the entire mechanic actually interesting to actually play out - and they know it because an auto-skip unlockable can be bought later on.
The real meat of this game comes from juggling the five heroines in terms of doing lewd things to them, as you want to corrupt them and max their lust level to unlock more scenes and be able to select their ending at the end of a playthrough (7/2, save the date!) Trying to unlock scenes efficiently is partly fun, as then you can actually try to plan out your schedule to balance everything and min/max, but there's a limit to that enjoyment. Because there are so many heroines the pacing of the corruption is completely off - the combination of low dialogue and the fast-paced escalation of molesting to full blown 3p h-scenes means you don't get any sort of feeling of really breaking down the girls' moral centers. The girls don't even feel like they act different from the beginning to the end, the only real difference is that you see their partners-turned-cucks crying and jerking in the sidelines.
With that in mind I'll talk about the h-content. 5 heroines, all voiced, all animated, but animated here is very loose as the job was done very poorly, with the cock not even entering the woman's hole half the time. Alot of the time these animations will look jerky and there will be much to be desired. No option for fully/half/naked clothing which I would have greatly enjoyed for this kind of game. Scenes and animations are drip fed to a satisfactory level - for most of the game you will be seeing something new but by the 2/3rd mark of game completion youll see how often animations are reused, and scenes will have no difference than another except by the location, or by the prescence of a cuck in another room. A positive note is that you can zoom in/out and move the focus of the camera, which lets you fully control how you want to enjoy the animation. 1-3x speed with progress bar lock and auto mode available too - although i wish there was a skip button considering one of the girl's routes involve seeing a bunch of scenes repeatedely, coming back to that "this game doesn't respect your time" thing i mentioned earlier.
Despite the game being objectively bad there is the ultimate strong point of the girls being very, very, cute. That's just how it goes - you make cute girl game can be dogshit. The game's strongest suite is that it really does give you new and great things to enjoy on a consistent basis for most of the game. Your dick will thank you.
Usually I'd say to grab a full save but I think there's something to be gained out of the experience of having your time wasted (Plus all of the molest scenes are only available in-game). In the most time-wast-y routes one of the girls does a surprising action that leads into a sweet h-scene. I didn't see it coming and I'd be remiss to say that experience is worth skipping through for yourself. So, use the exploit like I did so you can focus more on the h-side of this game and not the grind.
