Hermione's reactions were absolutely priceless and Luna loved them all. She grinned around the length of Hermione as she bobbed her head idly, wanting to coax even more out of the brunette.
"Am I?" Luna asked, removing her mouth from the cock for a moment to take a breath, though her hand kept stroking it, now slick with Hermione's precome and Luna's saliva. There was a familiar playful gleam in Luna's eyes as she smiled up at Hermione.
Returning her mouth to the member, Luna took more of it in, all but about an inch, in her mouth, sucking for a moment before beginning to move her head up and down in an agonizingly slow motion.
