It's ok for what it is. but it reeks of the 'power high revenge fantasy plot' that I hate so much in VNs and LNs, even if the story is mostly an excuse to fuck the girls. The characters only exist to metaphorically and physically suck the portag's dick (which mind you, isn't that big by the way. He's just asking to be NTR'd so fucking hard), and have no real significance traits once they do get dicked or even before, they might as well be the same person by the end.
The sex scenes and art are mostly good, but get the dialog doesn't evolve past "Nooo~~~! I can't lose to your cock! Even if it feels good, I won't submit ♡ !", to "Ahh ♡ , your dick feels so good master! Please give me more ♡ ♡ ♡ ! I wanna get pregnant!", and "HORA! Take it all you dirty slut! You're my fuck toy forever now!" for all of them. Plus, there is an absurd amount of watersports here, all from the guy too. I don't mind it when its done in moderation, but when he pisses in the girl's snatch on nearly every single scene, it get very old and pretty disgusting.
