My Sensitive, Hardening Nipples ○○○○○○○ed Masochistic Older Sister Super-Hard, Ridiculously Hard Nipples

Constantly erect. The most symbolic female features—full breasts and the protruding nipples.

Then, it turned into a completely out-of-control shoot as they demanded things like "Pinch them!", "Pull them!", "Bite them!"!!
