She bangs Ron

Hermione stuffs her rod in Ron’s twat, causing him to bolt awake. She crams her fingers into his mouth to muffle his erotic cry, making him gag on her. He spasms, eyes wide and darting to her face, her firmly implanted cock, her bouncing breasts. Ron convulses like a newly popped virgin, which Hermione supposes he is now - or was until five seconds ago. He wasn't prepared for his friend’s previously unknown mind-melting cock to churn his fresh female guts into butter.

Hermione is fast, efficient, she’s had plenty of girls before now, and has perfected her technique. She shifts her weight to match Ron’s squirming angle, knowing just how to induce a girl’s most euphoric sensations without tipping them over the edge. Ron is on the receiving end of the best sex of his life, fully overcome by his new feelings.
