Nyuubu Shitara Ore Igai Zenin Ero ROM Layer Datta (“When I Joined The club, Everyone But Me Was An Erotic ROM Cosplayer”) [English], by Sage Joh
It’s funny somehow, originally I was planning to share another work by Sage Joh, downloaded early June… But I finally discarded it: it was shota and the art was actually far too mediocre, save *one* picture, the one that convinced me to download it. However, that made me notice another release by Sage Joh in my downloads folder, that one is older but MUCH better in my eyes
And so, here’s this one, in which a young college student joins a photography circle… and discovers it is a porn photography circle
The 3 girls that greet him don’t waste a single panel, it’s instant sex ^^
The drawings were a bit too censored for my taste (many black bars), but the drawings strongly reminded me of the early days of Tosh, a mangaka you may be familiar with, they looked awesome…
Release credits are for Zek3, Fort, Proto, Owen and Koizu, from Insurrection Scans, thank you!
By the same artist, to this day, I also share Papa Ijou Koibito Miman, Onaka Ippai Ooo Ga Tabetai, Sexual Pleasure Songstress, the excellent Absolutely Lewd Adults, Sex Shinai To Derarenai Nara Shikatanai Desu Ne, Macross.Zip, Ero Shuurai Asuka’s Case, Ota X Gal, Hatsutaiken Jeanne, Shaburotto Dunois and Ero Shuurai Rei’s Case.

Whelp, there goes another male protagonist in the H-Universe who qualifies for this:

Wonderful flesh in hideous outfits, it’s Indiana all over again.
“Wha??? This story makes no sense!”
Jumps to the main page, clicks on a download site.
“How could this club possibly exist? This is idiotic!
Clicks on low-speed download, waits for timer.
“They just leap right into sex? And they all just HAPPEN to be gorgeous?”
Verifies not a robot, clicks Save with right-handed waldo unit.
“Just a terrible, terrible story! There’s no plot!”
Patiently waits for download to complete, muttering, “Damn.”
LOL, when the organ grinder turns the crank, we all just dance.
Rattles cup, adjusts collar, waits for the next song to start.
You duplicated Hatsutaiken Jeanne’s entry.
Woops, you’re right O_o
I’ll remove the spare, thanks for reporting it man!
