Kussetsu

First off, from a hentai perspective the sex scenes in Kussetsu are conceptually arousing however the art is dated. However this brief ova is satisfying on another level.

The mc is the antagonist and an egomaniac, he plots to take everything away from his only friend, because secretly he despises him.

We're given no reason as to why the mc is supposedly unpopular, but it's clear he is a dark character, however i couldn't help but root for him. Two by two he manipulates the women surrounding his friend and proceeds to fuck them.

What i like most about Kussetsu is a romance that develops steadily ... throughout, one of the girls he seduces is like himself, a daughter of a politician, they share a wicked scheming mind. They deserve each other, and they're bound for a future in politics. Also the punchline is quite well delivered.
