Takahashi, the one with the blue hair, is a girl who wants to be seen as cute by her boyfriend, but in general she is seen as a prince. The protagonist wants to take advantage of this to make her dirty by making her think that she is becoming cute.
In simple, vulgar terms, the girl wants to be dominated by a man, to be treated like a woman. I mean, this should be easy to develop.
- Takahashi's first scene: it dragged on far too long.
It's a kiss, which isn't bad, but it's practically all dialogue about the protagonist's impressions, and we couldn't care less about the protagonist, and just moans from the girl. In other words, we didn't see anything that could make this scene interesting except at the very end, where the girl blushes and gives her impressions. The scene could have been easily fixed if it had been seen from the girl's perspective, with her thoughts on the situation, but oh well.
- Edit 1: You've got to be kidding me, the second scene is pretty original where Takahashi sends selfies to the protagonist, because he makes her believe that sending photos to her boyfriend the way he tells her to would make her look cute, but it didn't last a damn shit, hahaha. You're kidding me, the kissing scene lasts 3 or 4 times longer. Damn it, when they want to, the scene is unnecessarily long or, as in this case, unnecessarily divided, because I doubt this won't have a sequel.
- Edit 2: Third scene. Blowjob in the girl's room wearing a catsuit after she sends her boyfriend a selfie in that outfit. What could go wrong? Well...
The scene isn't bad, but I can already see the major flaw, I don't know if it's a problem with the whole game, but it seems to be with Takahashi's route: lots of moaning, few words. Basically, Takahashi just moans, doesn't say anything, and since we see the scene from the protagonist's perspective and not hers, or a general one, 70 percent of the text is the protagonist's thoughts, 15 percent is the girl's moans, and the remaining 15 percent is the dialogue before and after the scene.
Although, well, if you get turned on by reading the protagonist giving descriptions that you mostly ignore or already know, or him describing in a thousand ways how good it feels, well... it probably turns you on, I don't know.
Edit 3: Fourth scene, first time, but in missionary position, the most used, simplest, and mostly most boring position there is, unless you film it from a good angle. Sure, it feels good, but only when you're doing it, not when you're watching it.
On top of that, it's a typical Saimin Seishidou scene: sex in front of the boyfriend to inflate the protagonist's pathetic ego. A total meh, and because of that, plus the disappointment that was the redhead's route, I'd better stop here and go to sleep.
