Shibunama [English], an hentai doujinshi parodying the Idolm@ster series, by Ken-1 (AKA Cior)

Apparently, Shibuya Rin, one of the Idolm@ster idols, is troubled, in the middle of a heartbreak or something. Basically: vulnerable. She meets a fan, and one panel leading to another, she’s having her first time with him in a love hotel. That was fast O_o

Fortunately, largely making up for the gloomy atmosphere, the drawings are SPLENDID
The subtle tones, all the quality details, Shibuya’s face and expressions, her beautiful breasts, the hardly noticeable censorship… A lot of time and skill has been poured in every page, this is really a worthy sight, woah, hats off 
Thanks to Doujin-Moe for commissioning the release of that volume!

By the same artist, I also share a pack of 8 translated works.
