[JJK][NSFW] Our Lord enjoying a bath

One day I may stop drawing NSFW in a warm light setup but this was not that day...

Also, I just realised: true form Sukuna has black nails only in one of the early colored artworks (probably him in from the Heian era), and the one hosted in Yuji. Normally I'm not a huge fan of unnatural nails, but visually they compliment his tattoos, so I don't mind that I drew him like this, even if I feel a bit dumb now.
