Just Found My Fetish... Late Bloomer?

So yeah, I was in the kitchen making dinner for my wife one night when all of a sudden this idea popped into my head...what if I pretended to be her strict teacher and she had to do homework as punishment for being naughty at school? It felt weird but also kinda exciting. I never thought about something like that before! So the next day we decided to try it out in private, you know? And it was amazing! We laughed a lot too...but I still think about it sometimes and wonder if this is just something fun for us or maybe more serious? Like am I suddenly going all in on DDLG at 42? It's pretty wild stuff to wrap my head around. Still processing it all, you know?...
