I've been looking for a couple of videos produced by the studio pacopacomama with an actress going by the stage name of 真理 (truth).
Most if not all the pacopacomama videos can be found on free jav sites but the ones made with her seem to have been lost.
The specific videos are : 
Pakopakoma Yu ○ Similar, pregnant woman 7 months pregnant Mari (パコパコママ 優○似、妊婦妊娠7ヶ月 真理) 
Paco Paccomama Yu ○ Similar, pregnant woman 7 months pregnant 2 truth(パコパコママ 優○似、妊婦妊娠7ヵ月２ 真理)
with the (now not working) links being

After doing a bit of digging, i found a few websites hosting image archives of her work:

After even more digging, i managed to get

(downloaded with command "ffmpeg -protocol_whitelist file,http,https,tcp,tls,crypto -i %_url% -c copy video.mp4" in a .bat file)
which turned out to be an incomplete version of another video produced with the model.
Any help trying to find these videos would be appreciated.
