Her flesh was on fire, and with every thrust he filled and stretched her while also pressing against the heated skin of her buttocks. His palms came to rest on her arse, the comparative cool of his skin a relief to the burn of her own, and then he murmured a spell and she felt him press a lubricated finger against her anus. She whimpered, but he did not slow his tempo as he slowly pressed the finger forward, breaching and stretching her slightly until his finger was as far in as it could go. After withdrawing it as gradually as he had inserted it, he added a second finger and she moaned at the intrusion as he continued to thrust inside of her. She could feel her legs starting to tremble. The stretch and friction combined with the arousal she felt at him taking her on her own desk and her breath began to come out in breathy gasps with every thrust.
