21-ji no Onna: Newscaster Katsuragi Miki

Miki Katsuragi has finally landed her dream job, as an anchorwoman for the nine o'clock news. Unfortunately, this pretty reporter with a spotless reputation has a very dark secret. She`s addicted to masturbation, and she can't stop for even a second! When she is caught using a vibrator on the air by the cue-card holder, she's in real trouble. He`s not above a little blackmail, so she's completely under his power. Not only does he show her what the real thing is like, but he also installs a remote-control vibrator into her panties for fun on the air! (Source: AniDB)
