Hah, this reminded me of this one hentai doujinshi where a magical girl stayed as such even after she became an adult and got married... with the doujinshi revolving around her ambushing her hubby on the train for a quickie to recharge her mana reserves after a battle against a monster (she used an illusion spell on the people nearby so they won't notice).
You can't just say that without giving the number mate...
Why should I give you a number... when I can just give you the name? (It's Magical Wife by Shinozuka Atsuto, BTW)
Plus, I didn't know if anyone would've been interested, since this site is primarily dedicated to yuri with practically no het art or comics being shared (AFAIK).
