There was a series on MONDO TV featuring gravure idols that was called Megamikourin 女神降臨 and episode #87 airing on 2014-01-17 featured Yurika Tachibana 橘ゆりか. These are 23-minute episodes. I found an old torrent for all of the Megamikourin episodes, but unfortunately there are no seeders for it. The file I'm looking for is listed in the torrent file list as '女神降臨 #87 橘ゆりか.mp4' (1.62 GB). There is a video preview of it here.
I was able though to find the very first episode in the series which featured Risa Yoshiki 吉木りさ.
