Hearing Hermione's whimpering, Luna knew that the girl was enjoying her actions and wasn't going to push her away. Feeling more confident, her strokes became more firm and sure through the fabric an she could feel the cock swelling.
"Maybe." Luna answered. She wasn't sure that it would completely fix the whole problem, but she could tell that Hermione needed release. "At the least it should help curve your randiness problem. For now."
Blushing as Hermione spoke in her ear and feeling the lips on it, Luna drew in a breath, herself getting more and more randy as the moments passed. "I can have sex with you." She answered bluntly, looking Hermione in the eyes and gave a firm stroke to the girl's member.
