Gintama dj - 3-nin Douji ni Ikanakya Dame?

From [Baka Dumb Aho Scans](https://www.mangaupdates.com/groups.html?id=5647): Pairing: Hijikata x Gintoki + Okita Gintoki, Hijikata, and Sougo found themselves trapped in an enclosed room. A person appeared in the monitor and told them they must make themselves cum at the same time. (Parody of episodes 148 and 149)
