Gentle Rhythm 5 [English, Full colour, Uncensored], an hentai doujinshi parodying the Touhou series, by Mana
Here’s a nice but short one, 16 pictures in total, about Kasen, one of the touhou characters, tricked (the mood’s to comic relief, nothing serious) into becoming super erotic around two equally horny shotas, until the final (dick) boss shows up ¯\_(ツ)_/¯
The drawings have a unique style, it was great eye candy, with a certain manhwa feeling I can’t quite put into words.
At the very least, I think it’s worth the discovery
Thanks to Belldandy100, for both the translation, and the decensoring!
By the same artist, I also share Fate Gentle Order volumes 1-2, Fate Gentle Order volume 3 + Alter Volume 3, and Gentle Blue Fantasy 3.
