Gold Throbber

Yuji is a young businessman with a penchant for groping women on the train. Unfortunately, he's really bad at it... His hobby is about to land him friendless, homeless, and probably behind bars. Enter the dashing hero, Kazuo, the man with the Golden Touch, any woman he touches turns to be horny! Touched by Yuji's plight, Kazuo takes him under his wing and teaches him to score with any woman, anywhere, anyhow. (Source: AniDB)
