[Soboro Laboratory (Yoshida Soboro)] Classmate no Succubus-chan no Aite wa Boku dake ja Nakatta Hanashi [Digital]

Could do without the slut calling, but I like the take on succubus in this story. Most of story in ero doujin seems to either make her bound to a single human (mainly vanilla story), or unable to fight her instinct and fall to the rapist betraying the person she loves (NTR story). In this one, it's purely a difference in values. While he (human) see sex as proof of deeper relationship, she (succubus) see the friendship as a more special relationship than just feeding (sex, which she can do with just anyone and call it a day). She did say, she hesitate in telling it because she also know most people wouldn't be able to comprehend a succubus' way of thinking.

Well mc should just give up on that succubus slut and move on to find a better girl

Very nice

The succubus in their world seems to be like changeling rather than hereditary. Shimizu's parents don't like the fact she's a succubus, so she often have to skip class during middle school, and that's when she first met with Satou, who offered to help her sex need. He studied hard to enter the same high school as her. Satou tried asking her to be his girlfriend, which she turned down because she's succubus, but he's not giving up. | Now, Satou loves her. He thought she's not like typical succubus, and he's special as the only man she had sex with. He doesn't like the realization that she had sex with many men now. Meanwhile, Shimizu sees him as her best friend. Sex is different thing, as she embrace her nature as succubus. She did ask him, and while he hates and can't understand her logic, he always said he's not bothered; probably too afraid it means if she will be faced with choice, and she will pick her nature as succubus rather than him. So it's not like other men steal her away.

so she is a slut and the guy misunderstood her for a lover???
