breast feeding kink

Hi Guys

Me (F23) and my gf (F21) were having sex and she was sucking on my bitties and we started talking/playing out the fantasy that she was going to receive milk from me. It was really hot and we both got off on it.

Afterwards there was a moment of silence and we were looking at each other like was that weird to do? it felt good for both of us but I guess it’s not a very common kink or fetish that people discuss.

She wants me to write this to see what other people think on this? Is it normal or is it kinda freaky?

Thanks!!
