This is (as far as I know) an updated version 2 and bigger file of this previous version by Chihiro: [\#195770](//www.nyaa.se/?page=view&tid=195770) which came out May 2 following the February 24 release. In theory this should probably replace the previous one. I'll post a link to this there. This is the third in the series. The first 2 Hinako OVAs are "training" and "sleeping". Now you will learn to bathe. I added Hiyoko to the title since she's supposed to be in it. I found out about this version 2 via someone listing it on Animesuki: http://animesuki.com/series.php/1781.html
