Uzuki No Himitsu (“Uzuki’s Secret”) [English], an hentai doujinshi parodying the Idolm@ster Cinderella Girls game, by Meganei

In the real world, if you caught a girl masturbating in your office, you’have to flee to another continent, there’s just no way it could end nicely for you, even two decades later molesting suspicions might catch up on you.
In the hentai world, you defuse her shame by offering to show her that, you too, you masturbate ¯\_(ツ)_/¯

Anyway. Uzuki Shimamura has the chance to be caught by her producer, and the real thing is better than any solo fantasies, excellent and enthusiastic sex follows
The sex was drawn fairly well, and yet my personal preference was on page 20, when the two youngsters took a break from thrusting hard, to turn around and kiss… awww =)

Thanks to Obsoletezero for this release! And sorry if I joked about the typo page 18
