Like I said earlier, how many dudes even are there in Heartcatch? You have the Tuxedo Mask like dude, the Kung-Fu wiener, the ramen baseball wiener, their dads...that's about it. How many doujins could there even be that aren't :sdburton?It's not :sdburton material. You wouldn't like it!
Unless you're reading wholesome, family friendly doujins.
Wait, how can there not be many :sdbuton Heartcatch doujins? Moreover, how can there be more that are also smut?
