There was a limit to what she could do in this position to mark him, but she didn't plan to move just yet. She had him right where she wanted him and to move too early before he had control of himself would just ruin whatever time she put into this so far. What she was ignoring was the fact that she was only human and getting turned on by this as well, despite the supposed lack of reaction to everything they were doing together. Feeling him inside of her, her body tight around him as if to keep him in place, was making her legs tingle and cause her take notice of her own physical responses. It wasn't the time for that and she did her best to push any desires and reactions away.

Because she couldn't mark him properly just yet, she moved herself back into her sitting position and grabbed Peter's arms, pulling him up with her before she kissed him, rough and controlling as her hands wrapped around him. Robin growled into the kiss, wanting nothing more than to show off her dominance to the sub that she was claiming as her own. Then she revealed the main reason she had repositioned them a bit by having her nails dig into the skin on his back and dragged them down his back, using them to mark him where she couldn't with her mouth.
