"Your wish is my command," he whispers playfully with a smile, nipping a little at her ear. "Warn me like you usually do then, okay?"

He'll leave it up to her if she wants to try to come or try to resist, but he appreciates the warning to make him not have go guess, even if he's pretty good at reading her by now.

The first time he doesn't wait for a warning though, not wanting to push it too close, just warming up. He just massages her for a while longer, before he pulls his hand back and licks his fingers, then instead going to gently play with her breasts and nipples for a while.
