About Succubus Research Diary

Nerisha is a young adult succubus who has never had sex. This is something of a problem to her because succubi can't fully develop their magical powers unless they have some sweaty fun with humans or other humanoids. However, having high ideals of equality, Nerisha is unwilling to get herself a sex slave as most other succubi do.

Serena is a human explorer who got separated from her expedition after something unfortunate happened. She's a mature woman with plenty of sex appeal that she doesn't hesitate to put to good use.

The two women meet as Serena accidentally stumbles upon Nerisha's doorstep. After learning of each other's circumstances, they strike an unusual deal. A deal that involves the two of them having lots of sex...

You would think I would have learned to turn off all sounds by now, this game will teach you that. This is not full autoplay as the other book The foreplay is where you have to click to continue. I would click and leave because the words on the screen were something a doctor would say before touching you. Major ick and just when I thought I was away from all that I heard mac and cheese followed by a plastic drumstick hitting the counter. When I went to close the game the girl was talking about her big sexy hard dih. The shortest limp dangle I have ever seen. Pls. This was a horror game for me. I do not even remember what emoticons I wanted from this game If you found this one sexy please slide in my DMs so I can block you.

Cute adult VN focused on the lesbian relationship between a succubus and some kind of scientist witch or something. Sex scenes are a little bit on the softcore side, at least visually, though the written dialogue is more explicit than the artwork. That said, if you're a fan of yuri and don't mind a little optional futa content (again nothing explicitly shown), this game provides a pretty solid value.

It's so sweet and cozy, you wouldn't believe it is actually a hentai game. It looks more like a gentle fairytale at first sight. The background music is lovely too. And yes, it's still a hentai game!

Would be a lot better without the unnecessary and pointless addition of futa.

"With great power comes great responsibility" - some bipedal web slinging bastard, idk lol. Perhaps, this visual novel is not really my type. It feel interesting at first, but the excitement wear off very quickly when I realized the story is rather linear and repetitive. The world building is ok, but the more I play the less I care about it. For the story it's wholesome yuri + futanari visual novel about Serena, a lost and separated expedition member who happened to stumble upon a house in the middle of nowhere in the mysterious Underground world inhabited by Succubi. The odd looking house happened to belong to a very shy and kindhearted young Succubus lady named Narisha, who is also inexperienced to sexual acts. And in exchange for accommodation and safe shelter, Serena have to introduce Narisha to the world of pleasure in order to help the young Succubus gain magical power, at the mean time any interaction between the two will help Serena with her research about the Succubi. Beside the interaction between characters, this VN also focuses on world building, mainly about fantasy setting. *sigh* I don't know why do write reviews like it's my passion project *face palm*. Oh!
