MC is a bit small, and there's a few sprinkles of NTR theme, but it's not enough to deter me and there is sufficient and bearable closure.
Lilly NTR is unavoidable, though.
I'm pretty inflexible about monogamy, but it's something that comes off as appropriate to me.
She's a realistic succubus doing succubus things, and MC fucks her like an inexperienced kid with an opportunity and for plot.
I think the aunt is Netori, and the aunt's neighbor is promiscuous.
You can avoid both.
