[Zaki Zaraki] My Daughter is My Wife (Shougakugakusei) [English] [QuickAndDirty] [ザキザラキ] 小ガクガク生：俺の娘は俺の嫁 [英訳]

Mei's father finds his daughter growing more and more attractive and she knows it. She promises she'll be daddy's bride in the future (standard Japanese cute line), but he doesn't realize just how much she means it. She gives him a little push, and the next thing he knows they're going at it any time they're together at home.

In case it wasn't obvious from the title: this is a loli incest comic.
