Ginny play's

And suddenly there was something warm and wet on her, in that restricted, taboo place that she'd never even touched herself. Ginny's tongue was soft, was heavenly, and Hermione couldn't help but moan loudly and grasp Ginny's scarlet sheets until her hands were curled into tight fists.

"That's it," Ginny said, as she paused to take a breath, "tell me how it feels."

"Foreign..." Hermione said, but that somehow wasn't the right word.

"Foreign is good, love. It's new territory, it's slightly impermissible, don't you think?"

And then Ginny was on her back, pulling Hermione's hips to her, and she was licking at her cunt, sucking at it as though it were a fountain of the most wonderfully aged wine, and Hermione's head, once so grounded, was lost in a fog of gratification. It only took a moment for Ginny's very obviously skilled tongue to bring her over the edge of orgasmic bliss.
