This game sucks, dick and balls especially.
The story is this, you're some small penis cuck who met the devil in his time of need, who turns him into a big cock... cuck, he's still pathetic in personality. Who then, of course, use this power on his mo- I mean, "totally not related maternal figure who doubles as his landlady".
And thus began a power fantasy-corruption based plot, here I thought you only see those things in Isekais.
Basically you run around doing stuff, grind for power to corrupt yo girl annnnnnd that's it, really. There's some plot about you getting powers from a witch, you come into contact with a (female) devil, your body risks getting taken over by the devil that you had a deal with for the sake of a bigger dick; but everything either gets resolved so quickly that there's no tension at all, or that it doesn't and is never brought up again.
For the much of the game, there's only five person you can bang, your "landlady", a prostitute, some milf, your coach at the gym with saggy bloated legs, and the above mentioned devil chick.
However, these sex scenes lack substance since they're dependent on the magic points you have rather than actual progression; and they lack creativity too, as most of the sex scenes take place on a bed/wall with pink background, almost like it's suppose to be a greenscreen room that they forgot to do something with.
It's not really all that appealing either, since the camera angles are very awkward, the poses, and the character proportion looks practically the same; what's the point in switching character models if I end up looking at the same thing anyway?
There's about 8 NTR scenes in the game, while they're optional, they sure aren't worthwhile. While it's better than staring at MC's twink ass, the 8 scenes look practically the same with the "holy shit your dick is much bigger than MC, you're poking my belly and filling me up" dialogue and cum inflation, is extremely short, and disappointing for what's supposed to be "the gigachad" of the game. As much as I dislike the wimpy MC, if the NTR scenes are incredibly unsatisfying and non-contributing to the plot at all, what's the point of including them in the first place where a majority of vanilla guys would hate it?
But if you really want to know how the story ends, the ending goes:
MC defeated the devil after some extremely hasty planning with the devil chick, which you can decide whether to sell her out to the devil so you can bang your "landlady" for the rest of your NEET life, or you kick the devil in the balls and take the throne for yourself.
Such a poetic conclusion, worthy of an Oscar or something.
Like, the game is not the worst ever of this site, but it's incredibly boring and mid that you're better off playing other games with E cup titties in them. That's my thought the longer I played it, which I recommend that you spare yourself the trouble and just, don't.
