Her face was like a chunk of granite, all hard ridges and cliffs.

The soft lines of his face set themselves into hard ridges.

He reached up and touched the hard ridge of skin on the top of his head.

Not even the hard ridge forming under her bottom could alarm her.

"No, here," he said, taking one of her hands and pushing it over the hard ridge that was his arousal.

Her hand under his back could still feel the rucked, hard ridges of scar.

Even through all their clothing, she felt the hard ridge of his desire, pressing against her lower belly.

Down each edge of the hands was a hard ridge of the same bony substance.
