>>23559857>>23560096I tried to find the sources of these photos in better quality and made a surprising discovery.
It turns out that there's a cosplay brothel in Osaka called Anihiro (アニヒロ, googlable). You can pick a girl, choose a cosplay, get a room, and... You know.
She's one of their "models". Suisex will cost you 13k yen for an hour:

But there are no pictures in better quality.
