This is utterly relevant to my interests. Here are a list of doujins I have compiled -- most of which I got on RS:
Kira Hiroyoshi: The Lecherous Membrane, The Noble Ilusionist, Love Letter, Representative Director, Tabetai Nametai Danchizuma
Po-Ju: Secret Journey 0-2 and 4 (3 doesn't really have the /d/ sized kid)
RaTe: Oneechin (pages 99-130 have the /d/ sizage)
Okawari: Love Subordination (dunno if there is more, but up through page 22), Kussetsu (137 onward)
Chanpono Miyabi: 01 Oneesan Tengoku. 02 Oneesan Choukyou NikkI. 03 Oneesan Kyonyuu Engi. 04 Oneesan Inran Kyoushitsu. 05 Oneesan Bakunyuu Datenshi. 07 Oneesan Kyonyuu Kinbaku Ingi... probably more out there.
Sago Jou: Nekotama Volume 1 and 2
Ando Hiroyuki: Bassatsu Harainin
