18+... that's some hardcore ear cleaning.

Then again, this doujin probably involves hot post-cleaning lesbian incest.

I can't read the kanji, but here's the rest. "Abunai yo" usually means "Look out!", but it's written as a question here, so I translated it as one. "Akikan" is another name the artist uses (may or may not be related to the series), and "Credit" is the name of his doujin circle.
