Notes:

Context: There's a doujin where Kira, already disguised as Kosaku, gets rammed by a futa-Shinobu. I mentioned in the thread that I had seen the doujin but not read it since I respected Jojo too much. After another post of someone explaining to everyone else what the context of the doujin was, an anon replied with this. It was gold, so I had to take a snapshot of it.
