Kaguya-sama Wa Shasei Sasetai volumes 1 and 2 [English], a pair of doujinshi parodying the Kaguma-sama: Love Is War series, by Kimigabuchi

Not gonna lie: if you request excellent-looking drawings to reach the pinnacle of fapping, don’t bother with the present share, the drawings are average, at best.
BUT: if you care for a good hentai moment, with 2 volumes that perfectly replicate the feeling we have when we read the real Kaguya-sama: Love Is War series, you’ve struck gold

That’s what those two Kaguya-sama Wa Shasei Sasetai volumes do: respect the idiosyncrasies of the original manga series (look, you can read it here), both in art style (which is why I view it as average, the manga’s visual style isn’t great) and in story type. The narration, the focus shifting, the internal monologues, wrongly viewing everything as a challenge for romantic domination, that was just like the real manga!!

I will avoid teling the contents of the volumes, as I’d want to avoid making spoilers. See for yourselves =)
Release credits are for Notjag, thank you!
