I wanted to try something new, so this time it's a background... of that pool.
The Hanazono Room even has its own wikipedia page - it was well-known as a location for hardcore AV shots, until the owners decided on raising the rent for it because of all the disinfecting necessary, so now it's only used for softcore gravure.
The trigger here is rei no pool. Useful secondary tags are pool, indoors, window.
This was trained on non-explicit images with this background... I wouldn't vouch for it not affecting the style, but it should kinda work at low intensities already, so you should be able to combine and weigh it. I hope.
