Chuu Kono Hon Wa Chou Amayakashite Kureru Onee-San To Ichaicha Shika Shimasen (“Warning: This Story Is About My Romance With A Super Sweet Girl Who Spoils Me A Lot”) [English], by Suihei Sen
Erm, that was good in itself, but perhaps not as good as my former Suihei Sen shares. No – scrap the “perhaps”, I just took a glance at them, this new release really doesn’t look as good
Behind this long-ass title, there is a simple and satisfying series of slice of life scenes between two highschoolers, in love, having sex while the girl wears different outfits (casual clothes, bikini, maid, naked at an onsen).
The mangaka’s talent at drawing cute girls (and boys! it counts!) is amazing, but this time there was too much contrast been the two partners, it kinda ruined my immersion. Even though that was *not* shota, with a girl almost two heads taller than her partner and always taking the lead, it didn’t press the right levers with me this time, it made me doubt if it really was vanilla. Too bad!
(But, still, again, if you don’t compare it to other works, it’s still an excellent release in itself!)
It’s been released by Hellsin and Eromegame, thanks for this!

The occasional rant about excessive file sizes: I downloaded it myself as a HUGE 322 MB archive, in which the images were 6071 px high. So far, only 2 persons told me they had monitors with that kind of crazy picture height. For everyone else, I deem it as needlessly big. I allowed myself to shrink the images to 3000 px before sharing, this is very high resolution already. And with that, the archive’s size fell to 51 MB, 271 MB smaller

Pleasant, I suppose, but I have to agree … artist has done (IMHO) better stuff than this; even the one where the MC is indisputably a “shota”.
Let’s Move On.
Not quite enough mass to be considered man-like.
