Hermione watched as it bounced back against his stomach, the tip already leaking a few drops of fluid, and reluctantly admitted to herself that he had an absolutely  lovely  cock. It was an average length but delightfully thick, enough that her jaw ached pre-emptively at the sight of it. She leaned forward and ran her tongue along him from base to tip, closing her lips briefly around the head, and the groan that sprang from his lips spurred her on. She gave him a few more licks, teasing just a bit, before she opened her mouth wide and engulfed as much of him as she could in one try.
