Have you ever wonder what it feel like when her breast is full of milk? How about what her nipples are feeling like? What about what she is feeling as the milk is draining from her breast. Before I start pumping, my breast get a little full..they sometimes feel hard. The nipples getting a little hardening, you can feel when the milk is coming in by how warm it feels around this area and when they get really really full they begin leaking by themselves when I start pumping out, at first I feel like a relief, the squirting out you can feel the milk coming out!
