Idolm@ster hentai doujin [English] : Nagisa No Utahime (“Diva Of The Beach”), by Shiratama Azuki

Nothing complicated here, this is a straight fap’n’go hentai work, about an Idolm@ster producer catching his idol sleeping in a bikini, she wakes up being caressed, and sex follws. The man is a tease, the girl is the “hey no ! i love your dick : moar ! stop it !” type, and the rest is up to you, if you enjoy the art or not ^^

I may have missed the info, would you know who to thank, for this release ?
