Ah! Megami-sama IF Doujin Vol 1 (English scanslation)
I scanslated this one back in 1999, and posted it to ABPEA and a couple of the free hentai sites around back then.
This doujin is by Tenchugumi, who have published a series of OMG doujins using the 'if what?" format.
In this issue, there are three Episodes:
1 Belldandy meets Keiichi and offers him a wish 2 After being kicked out onto the street, they stay at Keiichi's friend, who is a lascivious otaku 3 Belldandy and Keiichi wind up at a temple, and she engages the elderly priest in some 'training'
Notes: This was my first shot at scanslation, back in the days when scanslations of hentai doujin were rare and pay-for-play sites were plentiful. Most of the pages are flipped, but a couple weren't because they appeared to fit the storyline better. All images were cleaned up, de-moiréd and decensored by me. The entire process took about two weeks. Keep in mind that this was a first effort, so it's bound to amateurish next to more recent scans/transl groups.
