Naughty Lazy Chemical Shiki-nyan [English], an hentai doujinshi parodying the Idolm@ster Cinderella Girls game, by Kazuma Muramasa

Shiki, one of the numerous idols in the Idolm@ster Cinderella Girls game, with a taste for science and scientific experiments (bonus pic: ROFL), takes her producer by surprise and shares with him an aphrodisiac drug. (I’d really like to throw a spoiler right here but I’ll resist.)
The rest is sex

The drawings are cute, we could feel the mangaka’s liking for this idol girl, she was lovely, cheerful, a cute tease, there was a whole atmosphere of merry happy-go-lucky joy from beginning to end. As for the quality of the drawings, heh, check the preview pics for a confirmation, the art is great ^^
Thanks to Rapid Switch Extra for this share!

Smaller version incoming!
As of usual when ☑ the images are in high enough resolution and ☑ the archive is quite big for its number of pictures, and ☑ it offers a significant gain, and ☑ I have enough time to do it, if it may help, I’m offering you a smaller version, in which I resized the images, here from slight variations around 3020 px, to standard 1600 px resolution.
The zip shrank from 58 MB to 10 MB.
Personally, I prefer it for reading, and it takes less disk space.
