Oppai Heart 2... I knew that sounded familiar.
This is probably your best bet at a download link:
http://depositfiles.com/files/mcg48zk63
...which I found from this blog:
http://lactation-hentai.blogspot.com...rt-vol-02.html
...which is maintained by "bioblade" of the "Bakunyuu Baka" forums. That's as far as I can go in deducing how legit the link is. The entry popped up on Google Reader for me a while back. Didn't know it had a BE scene. Unfortunately, in the download links page, one of the sites is being a racist prick towards americans. (Damn FBI scared all the download sites shitless. >_<) Downloading from DF as we speak, but my internet connection's beeing bizarrely slow... It's only a 355 MB file. o_O
Alternatively, I also found this site via well-crafted google search. Running Google Chrome with AdBlock Plus, NotScripts, and Avast Antivirus, I didn't get anything.
