A couple old adult anthologies from the 80's by a defunct publisher. I scanned the first one myself, and the second one was scraped from public raws. If I see the 2nd volume for cheap somewhere (and if someone wants to scanlate it), I can buy it to scan. 600dpi TIFs for editing are in the torrents (and on Nyaa). Let me know if something needs to be rescanned. The first cover scan is by someone else who owns a slightly-less beat-up copy.
