Nodding, Luna couldn't help but imagine what Hermione's mouth felt like. She was sure the girl was good. She was the brightest witch of her age and all.
"Yeah. At least bigger that the one I've seen." She looked at the cock again. Personally, she thought it was quite a lovely one, that was just how Luna thought.
Hearing Hermione's hands against the stall, Luna chuckled as she swirled her tongue around the head of the cock. It had a nice taste to it, she thought. Taking it out of her mouth, she ran her tongue along the length of it, taking up the precome before taking the head back in her mouth again.
"Hmmm?" Luna purred and looked back up at Hermione as she called her name, the hard member still in her mouth, her throat humming around the length. She knew she was teasing, but she was curious as to what Hermione would do about it.
