"The story is about a man who goes to the house of a woman he suspects to be the culprit in a certain case for questioning, but ends up falling for the woman's temptations, and his rationality gradually collapses due to her techniques being so pleasurable."
My JP isn't great but from what I could read that more or less sums it up. This story is a sequel to /g/2085067/9d483363e3/ so reading that first may also help.
