Loading...UPDATE : this page is now obsolete. Better, including the present share, you will find the COMPLETE and UNCENSORED Onee-Chan’s Whisper manga,
on THAT page 
I think you have some chapters from " Oneechan Wisper " book. http://www.mangaupdates.com/series.html?id=53257

Happening Rough and Kega No Koimyou are not part of this tank.
Almost forgot, Selfish Sister it's not translated yet.
Hey i was thinking like if you can put them all together next time you have another update with a new Hanpera. Just a thought you don't have to actually do it just wondering.
You should just make a Hanpera redirect section ;o
