Zetsuai - Kreuz ID 373 (Doujinshi) — Oneshot
35 pages, from Onamichan, released Feb 24, 2019.
Description
Izumi is nervous before a championship game, so Koji makes him feel better with graphic fluidy sex in the shower. Izumi goes on to the game (with Wakashimazu and Hyuga as team mates) and kicks soccer butt.
Note that in Japanese, the number 3 reads 'mi' and 7 reads 'na', so 373 = Minami.
