Imouto No Tomodachi Ga Dosukebe Taishuu Fechi Sugite, Inkya No Ore To Kikenbi Nakadashi Hamemakuri [English], by Anon 2-okunen (circle Anon’s Flood Myth)
Science-fiction: things like spaceships and futuristic inventions. May happen some day.
Hentai-fiction: sexy girls aroused by whatever is gross with you. Never gonna happen
In this release, we’ve got 3 protagonists. The typical younger sister. Her older brother, a young adult, working small jobs apparently. And the sister’s classmate, who came to play, smelled the brother had poor private hygiene (me: wtf), and followed the brother to his room because that’s her ultimate fetish ┐( ̄ヮ ̄)┌
I was lost the moment the word “smegma” appeared, impossible to take it seriously. But, hey, it’s possible for hentai to be funny AND nicely erotic, as with this share: the girl is super hot, busty, meaty, a nice sex face, and with a 89 pages long volume there’s lots of room for plenty of varied action, from oral to all kinds of vaginal (my only regret was there was just two pages of paizuri and one with swimsuit sex ^^).
I hope this unconventional but pretty good release suits you, thanks a lot to Lewd Rider Ero!

The occasional rant about excessive file sizes: I downloaded it myself as a HUGE 597 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 83 MB, 514 MB smaller

She teased him into a frothy mess.
I only got to the end of this based on our blogmaster’s suggestion that, in the end, it was a funny tale. The last time I encountered a H-work that made so much references to “smegma”, I simply couldn’t finish it; to this day, I still avoid it.
Can sense a bit of the humor present, perhaps, but my overall conclusion is:
Kinda gross, but superb art…
