I am pleased that somebody else shares my enjoyment!
Having stimulated and extended myself with my nipple pumps, I often go on to use my electric breast pumps.
The large pointy nipples slip nicely into the breast pump cones (with extra lubrication), and the pumping action is so soothing, long and gentle.
It makes me feel so soft, so feminine and so vulnerable.
After a session, I often feel so extended, sore and titty, but I slip a pair of soft nipple shields inside my bra, which stop chafing and preserve my nipple perkiness (the normal bra cup tends to flatten my hard-won pointy bits).
