First I want to say that this is a “Takeda Hiromitsu” work (I love this mangaka artist), so that means it’s usually a NTR – mind break xxx doujinshi. If you don’t mind/enjoy that, then you will have a great time with this Hibike Euphonium porn manga.
“Aoi-nee is really very pretty and usually she is a typical university student, but… her hobby is cosplay, so she makes her own costumes and attends events wearing them. But it exposes a little too much so… I can’t wear this at an event. My panties are totally on display. What did you make it for? To have sex with you in, of course!”
Hope that more will be translated soon. Until then have fun with this little hentai masterpiece.
