That's all she had been waiting for, the simple permission to continue. Much longer and she might have slipped a hand down between them and taken care of her own issue herself, leaving him to suffer in his stubbornness. But he gave her the go-ahead, complete with his own insistent attention, and she pulled him in for another kiss instead. While they were pressed together, she did slide a hand between them, but not entirely for her own benefit. She wrapped around him loosely, taking a moment just to see if she could get him to groan or thrust up into her hand before she slowly guided him inside.
The relief washed over her, a tension she hadn't even realized she'd been holding easing in her shoulders and back. She broke the kiss to brace her hands on his thighs again and rolled her hips forward slowly, enough that she could feel him slide deeper. She moved slowly at first, but only at first. But those first few movements were almost tentative, soft, until she reached out and grasped his shoulder and began to move with far more intention. Phasma had always been acutely aware of how to move her body and what to do with it. It seemed this was absolutely no different for her.
