Coffee Liqueur : Suckled Brats 17

I work in Tenerife in Dante's bar after getting a job one summer.  The local coffee liqueur is called a Barraquito and every bar-owner worth their salt knows how to make a perfect one, but when Dante runs out of milk his reputation is on the line.  I step in as savior, using my breast-milk to have him mix up the perfect drink for his wealthy creditor and keep Dante's business afloat!  After closing he wants to know more about where I got the milk from and I'm more than happy to show him!
