Um, not extractly a request more like an alert, in a manga called '10 Carat Torte' by mangaka Rururu Kondo, there's a very nice BE scene in the volume 14 of the series. The story is about a bunch of apprentice witches serving their masters to earn merit. There's main character called Sakura (very busty in the first place) was zapped by some kind of shape shifting device and was given the command to let her boobs grow. I actually have the manga, but apparently I have no scanner. I think its a scene worth sharing, but painfully I can't share it myself (damn!). If anybody happens to find '10 Carat Torte' on the net, be sure to look out for volume 14 episode 249. I'll try my best to get this scanned anyway.

BTW: This series contains nearly all process material form TG, TF, GTS, BE, SW. The storyline is enjoyable so I think its worth purchasing and I believe Lorekeep has one of Rururu Kondo's comics in the free section.
