Has your partner ever done this before,?

So my boyfriend told me he's tried breast milk before when he was dating this girl with a kid. He said it was in the middle of sex and it just happened. Yesterday we were having sex and my breasts started leaking. My boyfriend just grabbed me and drank my milk pretty much lmao. I didn't even notice at first cos I was trying to concentrate on something else. He looked like he was having the time of his life 😂 I'm just glad he didn't freak out about it, not that I'd expect him to since we have a baby together.
