It's frustrating to move like this, pressing into and rocking with her without ever pulling back or away. Frustrating, but also teasing in a way that makes his blood rush, his pulse pounding in his head. He can see the warmth in her with his goggles off, see the way she's reacting to him and to this. That's another type of rush, his breath faster as he circles his hips like she does, as much as he's desperate to pull out and push back in again. He isn't sure how long that continues, only knowing that he can't stand it any longer, his strength overcoming hers as he pulls back, drives back into her with a cry that's unexpected.
