I'm looking for an anime that had a scene where the shy, boyish MC is talking to a sexy older woman in a red/black kimono who is either at a shrine or a boudoir. The woman is thicc and I think she is a ghost or a spirit or something. She is facing towards the shrine while the MC is talking to her from behind. She is very flirty and she is wearing the kimono bare shouldered.

I just need the name of the anime, but a link to the scene would be great.
