Here's the preview she posted for it on Twitter. Her Fantia got temporarily banned when she posted it there so not sure how to get the full thing. Maybe if you ask her directly?
New birthday Fantia post: https://fantia.jp/posts/3953809
Trimmed it down to when she starts stripping and playing with her sensitive nipples.
Seems like there's more premium versions locked from me so if anyone can share it is very appreciated! https://bunkr.pk/f/Add0jmKw9x43H
Also apparently the original version got removed on Fantia because it wasn't censored enough. It was uploaded there more censored but I believe the one on her OF might be the original with lighter censorship. https://onlyfans.com/2682843552/irocya3
