Zeph wasn't going to tell her that he was very interested in pounding that huge ass of hers, or hitting it from the back, just so he could feel it slapping against him each time he thrust into her spider cave.

The safe word was badge. It was a dig at Prima, but even she didn't care that much. It was rare for her to join them anyway.
