Is this a enjoyable corruption or one of those games where your "innocent" wife gets wet for other men the first time one appears before her eyes?
More the latter. I wouldn't say there's corruption in the sense that it's usually meant in these games, even though there's an actual corrupting influence once the
succubus arrives. Claire grabs a stranger's dick and pouts when he doesn't slip it inside her on morning two, without any encouragement from anyone save for the owner of said dick (and all he had to do was show it to her). There's no slow burn or gradual, step-by-step process of turning her into a hornier version of herself. In general, it's a relatively brief and
very fast-moving story about a guy who wants his girl to have sex with others and a girl who very quickly concludes that she wants the same thing. There's an unquestionable "good girl gone bad" arc for Claire, but it's as much her own interest as it is others (including her fiancé, her friend Olivia, and — at least at first — Darryl) pushing/encouraging her.
To the extent that there's gameplay (and there isn't much anymore, now that most of the branches have been removed) it's mostly about how far she's going to go, which has an affect on her relationship with her fiancé/
husband.
There's absolutely no reason to play it if you're not okay with sharing; there's only one unique scene left from the old non-sharing route (which makes the MC look like a lousy lover, because he is), plus a minor change to another scene. If you're looking
for a reason to play it, the only one that matters is that Claire's incredibly hot and you want to see her
taking a fair number of (mostly black) dicks. That interested me enough to download and finish the game, though I fast-forwarded through all the stuff I'd seen before. Don't play hoping for sex with the other characters, either (though the dev says there's a little more content yet to be added). There's one (brief, non-interactive) sex scene that doesn't involve Claire, but it doesn't involve the MC, either. The other female NPCs show a fair bit of skin, but that's about it.
