My males,
If you pump, be it your nipples or your breasts, let me introduce you to Nipple Crack.

It's not only a restorative for dried, cracked nipples. It's a preventative, think chap stick for your tits. If you get dry, and as a pumper I know you do this is healing.

Side benefit, it's also an insanely beneficial lube for pumping.

I now have sustainable A cups, and am well on my way to sustainable Bs.
