Summoning your nun fuckbuddy's shadow clone to help as a wet nurse and then milking each other until you activate your second sharingan and pass out is a bit fucked up when you think about it. And all of that in front of a child.
This nursing play is seriously not my thing so I'm just admiring the wholesomeness of Lupina and the baby. I also expect the baby to use her wings and fly out the window at some point since kids have innate magnets pulling them to danger
