The series itself is fairly vanilla, there's no absurd or over the top sex scenes, but the last scene is fake/pretend rape so that may make some people uncomfortable.
There's 5 main girls, all voluptuous and craving sex as soon as one of the special cards the man is in possession of is whipped out. All of the girls are pretty attractive, and they're pretty distinct from each other. But with the hentai running for about two episodes at 15 minutes each, their scenes are somewhat short. The middle aged man is the other notable character, and
this is definitely one of those "Ehh, I don't know if I'd be into this" kind of thing, but fret not, dear viewer! The man is incredibly bland, having no eyes and a generic personality, so you're really not gonna be thinking about him at all. You're mostly in his perspective.
Art was solid, looked really good in the sex scenes. There were no obvious art errors either, which is usually common in hentai.
Sound was good too, the VA for the girls all did a good job. The background music was subtle.
There's two primary issues I had with this hentai.
1) The cards. The man is given 5 cards in exchange for a large sum of money, but why do these girls want these cards? What's so special about them? Well, unfortunately that's left as mostly a mystery. We only get a small explanation. This franchise spans multiple different series, so perhaps it'll come back in another one and get explained there.
2) I wasn't a fan of the girls proclaiming their love for "the middle aged man's large dick." This kind of dialogue comes up multiple times and pulled me out of the experience each time. I didn't really need to be reminded of that, thanks (Although I'm sure that's the kind of audience they were aiming for in the first place).
Overall, if you like vanilla hentai, it's definitely a good quick watch.
