Simple request, stories about heroes/heroines who are pursuing some sort of lewd vengeance against someone else. Especially stories where the hero goes after a bully or a bully's girl, or where he takes revenge for an NTR event in one way or another. I've seen plenty of versions of this animated, though I can't think off the top of my heard of any good manga. Only requests are that yaoi be excluded as well as the exceptionally grotesque.

Try Musa. It consist of two chapters. It's not a vengeance though and not too perfect ending, but the bad guy got what he deserve and I think it is satisfying. Just a little warning, keep yourself calm throughout the story because you might get angry or heartbroken due to the brutal things the bad guy do to the MCs.
