So a couple of things to note: this is at first glance a generic 'i reincarnated and have a sh**ty class and so get looked down upon', but horny version. The MC has a passive skill that gives him great recovery power, which affects his... refractory period I guess lol.
Once you get past the generic looking premise (which you've no doubt seen a thousand times) though, this actually is quite good. It's ridiculously hilarious, like laugh out loud hilarious at times. I mean, it's no Greatest Estate Developer, but it's definitely in the tier right below it.
The art is really good, and the women are hot (and yes, graphic s*x, so no kids here, 18+!). The MC is actually really badass, which is great, and he's not bumbling at all. It also conveniently skips his awkward childhood/adolescent phase. He's already a fully fledged adult, and has clearly HAD that whole LN/WN tragic background... it's just not harped upon over and over. He's been exiled from his family (details unknown), clearly loved and lost, etc. So yeah, it's nice to have a protagonist who doesn't have to have that all onscreen at the start of a story, though I'm sure it'll pop up in the future. There is a wealth of plot just waiting to be explored.
Honestly, and I don't mean this in a bad way, but the porn ALMOST gets in the way of the story. Nah, that's not it, it gets in the way of the RECOMMENDATIONS lol. Without the porn i bet this would be very well known. "Unfortunately" it has it and therefore it's all too easy for someone to just write it off as Yet Another H0RNY Isekai With Nothing Else Going For It.
When in actuality it's really good. And frankly the adult nature of the story really adds to the comedy, and makes the cast more intriguing.
I'm only 13 chapters in, and I think i'll be looking up the source material right now. Recommended!
