I got curious, so I searched "ナズ" and "チーズ and "R-18" on pixiv. Excluding this comic, since it's not actually porn, there were actually 15 results. It seems Sanae's warning (read: punch) was not enough.
I don't...really like cheese all that much...Well... naturally, mice and cheese are...Marvelous! You won't let common sense hold you down then?Huh?BFHH!That'll prevent us from making Naz and cheese porn anymore!!!
