Chas knew he wanted her- it was hard not to notice- and still he was denying her. And fuck if that didn't make her angry, even with how good she was feeling. She didn't get that he wanted more from her, at the moment all she got was a distant thought that maybe she wasn't worth more to him than being fingered up against a wall. Maybe the reason he kept pushing her away was because she just wasn't good enough, wasn't worth it.
"Bastard." She growled the word even as she arched her hips into him. Tearing her lips from his with a loud "No!", she gave a whimpered cry, pushing her back against the wall to thrust against him. It wasn't enough, his fingers inside her; he'd gotten her all worked up and desperate for him and he wouldn't give her what she needed. "You're such a fucking bastard, Barty, please-" Screw not marking him. Her hands slipped under his shirt, nails digging hard into his skin as she dragged them down his back.
Her moans were mingling with desperate cries as she was pushed closer and closer to the edge almost against her will. This wasn't fair, it wasn't right. After all this time she just wanted him inside her, wanted to be his, wanted to come undone around him, and he was denying her again the way he always did. "Why won't you-" But her words broke off in a moan as she gasped one last time, "Please-" And then she came apart in his arms, body shuddering as she tightened and pulsed around his fingers, her climax taking her over as she cried out his name. "Barty!"
