I think Komurasaki has the Sensor-Sensor Fruit.
This fruit works through physical touch by amplifying the feelings and sensations – for the one on the receiving end of the action – that’s associated with it. This would explain why she is regarded as the best prostitute and why so many miserable men are willing to sell anything and everyone to be with her as it is due to the fact that she amplifies those ‘good feelings’ to a tremendous extent where they are overwhelmed by those sensations of love and lust and consequently are not able to think either rationally or empathetically.
It would also account for the observed strength of her slapping Orochi as the slap magnified the sensation of pain associated with it and that he felt as a result.
This fruit may belong to the same Paramecia category as Boa Hancook’s Mero Mero No Mi devil fruit as it would also work on the basis of the emotions felt by the one impacted by the ability.
Miss Goldenweek also has he ability to change the emotions of her target through the use of her colour traps.
But she never confirmed that it was a devil fruit so it may very well not be. However, I think both examples set up a precedence that there are and could be powers that work on the basis of manipulating bodily sensations and emotions and so I see this as a possibility.
