I was just sorting out hentai on my hard drive and found this one doujin. Looked it up here and couldn't find it by any means, just a later released and more polished one from Dashigara 100%, so I uploaded it here and tagged it according to the data on the The Doujinshi & Manga Lexicon page - and that's the problem: Is this from Dashigara 100% (on the credits page you can see something with 100% above the release date) or is this really from Hitori Tower Bridge? From what I got, Minpei Ichigo participates not only in his own circle, Dashigara 100%, but in Hitori Tower Bridge too, but still.
