Lots of, lots of dick sucking and cum swallowing. I get it, kinks are important parts of storylines, but there is no variety in this one. It feels like almost every erotic scene is for cum swallowing. I don't get disgusted by it to an extent, but this is way beyond it.
Other than that, this game could be much more interesting with some touches. First of all, wtf is the deal with the oddly large boobs? I can understand if the dev is a boob lover, but he doesn't even put them in use. There is almost no boob job, of which I am not a fan, but when you see all these women with large tits, you kinda expect something out of it.
Art is good and every scene, sexual or not, is shown from many different angles. The only missing part is not being able to see sexual parts from up close during erotic scenes. I wanna see more pussy and ass hole when they bend over or during a massaging session in prone bone position. I don't even remember seeing ass hole at all in the entire game. Other than that, I can say that the game is visually fulfilling, except for the animations. They are non-existent.
Slow corruption is almost well-made. It is mostly based on slut training and blackmailing (except for mom). However, it is not consistent. One character crosses a line several time. It is not picking up from where it was left off. You lick her pussy one day, the next day she gets shocked because you ask to see her tits. This may be fine for once or twice, but happens many time for almost each single character. You expect the corruption to be at a slow but consistent pace. This one just flactuates a lot.
Finally, some of the dialogues are repetitive. For example, when MC hugs his mom, he talks to himself about how he wants to fuck the shit out of her. There is nothing wrong with it, but he does that so many times.
Well, I can write more, but these are the most noticeable issues for me.
