Some kind of NTR doujin. ヽ（´ー｀）┌
I’m aware that someone else scanned this one, but the attempt was pretty bad (quality aside, the scan cut off some of the dialogue, which would have made any translation attempt… difficult). To be honest, this doujin kind of disappointed me compared to bbsacon’s previous ones in the series. Still good, mind, but less so than 2 or 3. The highlights for me were less on Tsukiumi and more on Musubi’s domming of Minato. Ah, well. Enjoy.
