She was grinning. Beaming, actually. He'd called her progress 'fabulous'. That, and he still wasn't wearing a shirt. He was trying to avoid people? She smirked at that, letting her face relax, finally. The praise was still bouncing around in the back of her mind, though. Then, it stopped, because something else had come into her brain. She smiled, eyebrows raised. She hadn't realized he'd heard her, but she was rarely shy about singing in front of others. She watched his eyes, noting just how let down he seemed, but the only thing Zelda was really thinking was 'say "sessions" again'. Her hands slowly moved to the strings of her suit bottoms, and began to re-tie the side nearest the Professor.
"I think it's an unofficial rule, that if you live at Xavier's, you have to stay busy beyond reason..." Her hands moved and she re-tied the other side then, both into perfect, bouncy bows.
"Actually, I'd like you to stay. Unless you've gotten too warm."
She shook her head 'no'. "Never." Too warm, that was. His smile and fingers gave her a shiver, though, and the electrokine was glad she'd fixed her swimsuit. Her hand reached out for his bare knee as she moved to sit up, and when her legs swung around, their knees were intermingled; his, hers, his, hers. She moved her hand up his thigh a bit to make room for herself, then watched his face. "Pr-... Charles?" She sighed, steadying herself mentally. "You've been inside my mind so many times... I can't help feeling like I want more. But..." she swallowed and her eyes stared at his chest instead of his face. "...not just that. I want to help you feel some of the goodness that you've helped bring to me." Her lips remained parted as she breathed slow breaths of the warm, wet air, and Zap looked up into Charles' bright blue eyes, under his floppy hair.
"Can I just...?" Her fingers moved from his leg to his belly, which was firm and hot from the heated pool. Another shiver. Static filled the room. It smelled ionic. She exhaled and her hand moved up to his pecs, giving both a feel, then letting her long fingers move over his shoulder. Her free hand came to the outside of his other leg, and she caressed his muscles, slipping upward until the tips of her fingers were under his swim trunks. His towel was moving. She grinned again, feeling less desperate now that she'd touched him; more cheeky. Zap bit her lower lip and her knee raised until her foot was between their hips, and she kicked his towel off with her bare foot, sending it flying. Her leg came back down, slipping to rest atop his, and her toes pressed into the posh fabric behind him.
