First Point: CHEATING SCENARIO IS NOT SUPPOSED TO LOOK THIS HOT!!!!!
Second Point: Daiki-san needed "more discipline than a Shaolin Monk" to ward off the temptation of a sexy and curious 'girlfriend's younger sister'.
Third Point: Does Daiki have what it takes to unlock the "consensual threesome relationship" route with Rine (his girlfriend) AND Asaka? And would Rine accept such a thing?
There Can Be Only One way to answer that last point (say-no-more, say-no-more).
Well...Considering he's already went and done it once, this relationship of their will probably continue. Thing is, will he continue to keep this a secret from his girlfriend, her sister, or will he attempt to go for the official 3P relationship? As in, with consent from the both of them.
If he goes for the latter I'll certainly root for him. When you have to choose, the only correct answer for a Hentai Protagonist is both/all of them.
Has there ever been a hentai story where the protagonist successfully fends off the dastardly female’s advances and leaves the scene?
If such a story exists, I’m all eyes and ears. But then wait, in true hentai fashion he’ll be captured and forced against his will to comply and copulate. At any rate, hot sister.

The artist is Maki Tatsuki. So, of course, it's going to be this hot. :)
