This was a strange thing for Tatsuki. As a superior being used to having a certain amount of control over a situation, her inability to make their bodies meet properly was bothersome. She couldn't give an honest explanation as to why, all information said she should have been able to, and though she moved her hips as to make it happen multiple times, all that happened was a gentle nudging of her entry. A slight pressure and slip, every movement of her hips caused this, even though she was trying her absolute hardest. There was a struggle here, one which she didn't know could exist. Though she moaned outwardly it was almost frustration, and it gnawed at her very being. Even as she was pushed closer and closer, and her hips moved faster and faster seemingly with the direct desire of making the lad take the plunge. It. Would. Not. Work.
This presented a different problem entirely as the lass continued, because now she had to make sure he finished as well, lest she have to explain why she'd stopped. Perhaps he wouldn't question it. Perhaps her teasing in this way could simply be how she chose to do this. And she'd continue her struggle until either he finished or he slipped within, whichever thing took place first. And regardless of the outcome she could maintain her current level of dominance. No one would have to know, that there was something stopping her from acting. Her fingers trailed back down where their bodies met and with every movement of her hips thereafter, she swiped the tip of him and her own source of pleasure. The flush on her face increased, why was such direct stimulation so much for her body, why did it feel like she knew exactly what she was doing to herself and the lad before her while she committed such an act. She would only be left to wonder while her body actively chased a pressure building deep within herself.
