Yogosareta Mitsuboshi [English], an hentai doujinshi parodying the Idolm@ster Cinderella Girls game, by JP06 (from the circle OrangeMaru)

Daaaamn, that one was morally heavy. You know how it works probably, not in hentai, but in the real world, the typical abuser profile?
Those scum persons with a gift for human psychology, who are apt at manipulating others to satisfy their own greed and selfish needs, who “trap” their victim into a mental prison and keep her (or him) as if captive beside them. Who take pleasure while making the other feel shitty, unhappy and dependant, and yet bestowing random happiness on the other from occasional little gifts and small words of apology without a follow-up…

Well, those kind of people, in this share, the Idolm@ster producer is like that. The story focuses on one of the idols, Mio Honda. She goes through emotional rollercoasters, experiences pain, sadness, hope, pleasure, lies to herself, and eventually, shocked despair overcomes her. Meanwhile, the drawings (oral, vaginal, anal) are hot as fuck.
Personally, I couldn’t enjoy a story like that, but I must reckon that, within this specific niche (not really rage hentai, midway between drama and bewilderment), this is actual quality, so maybe you’ll like it.

It’s been released by Doujin-Moe, thanks are an order!

By the same artist… *cough* – This time it’s a bit more complicated. There are two artists in the OrangeMaru circle: JP06 and YD. YD made Summer Lesson (Uncensored version), Chaldea Maid (Uncensored version), Chaldea Maid #Mash (Uncensored version, but with not-so-great scanlation and image quality), Chaldea Maid #Mash (censored version, but with much better image and scanlation quality), XX Rom (Uncensored version), Hidden Quest + OrangeMaru Special 08 (Uncensored version), a pack of 2 Uncensored works (Mousou Diary + Yaou), Hasamiuchi and Jidou Kouryaku (“Auto Capture”), while JP06 made Cosplay Kanojo #Mash, Cosplay Kanojo #Nero, Damegami Chuuihou and the morally taxing present share.
