..Little Barista...

I'm the barista at a busy cafe...and I've got this one customer who visits every day. He's a bit older than me and has these intense eyes that always make my heart race... Recently, we started playing a little game. Whenever he comes in, I serve him like a little girl... It's funny because most people think it's just cute behavior...but there’s more to it when we're alone... He treats me like his own personal doll, and it makes me feel so small but also so cared for....it's intense and it gets me every time.... Is this normal? Should I tell him how much I'm into being his little girl during our moments together?.....
