Muriel let him take the towel from her hands, watching him. She hoped the flicker of disappointment she felt when he mentioned his shower activities didn't show. It passed momentarily. He was young enough that it wouldn't matter too much, after all.
"What a pity," she said, reaching out to press her fingertips against his damp chest, then pulling away again. "I'm sure it would have been quite a show."
She smiled when he offered her a beer again, but it was a smile still tinged with the predatory heat that was gyrating through her. His offer was too casual, far too smug for her liking. She watched him a moment longer, thinking that sometimes, he seemed to forget he was dealing with a Slytherin.
"What I'd really like," she said, "Is to watch the look on your face with your cock in my mouth, but if you're all spent, then I suppose a beer will do."
She held eye contact for just a moment, eyebrow arched, then moved back out of the doorway, inviting him to pass. She hoped it was convincingly nonchalant, because saying things that forward still made her heart pound with a sick sort of thrill.
