Have you ever had a coffee with human breast milk? 

I have. For the first time last night. 

I also helped my friend pump her breast milk by drinking it. 

Directly from the source. 

Yes, that means I suckled from her nipple to drink the milk to drain her overflowing breasts. 

Baby was sleeping.
Pumping supplies were in baby’s room. Entering would risk waking baby up. 

Breasts were painful and leaking. 
Mama had drank wine. 
Milk was tainted. 
Not suitable for baby anyway.

She was trying to hand express, but it’s easier to drain the milk with suction. 

I’m a good friend.
I offered a favor to help her. 
Next level of friendship: unlocked.
