After what felt like an eternity, the door opened and Snape returned. Hermione had only fallen asleep once more, but the plug felt like it was stretching as much as she could possibly handle. She sobbed as he pressed a finger against it, and then sighed when he cast a spell to shrink it before pulling it slowly out of her. The removal felt unspeakably erotic and she felt empty with its absence. She then felt a smooth cool surface touch her puckered opening and she sighed as warm oil trickled inside of her. She felt his warm finger massage oil around and into her anus and her mortification at this unfamiliar and intimate touch was outweighed by how damn good it felt as she groaned in pleasure and shifted her hips. She gave an involuntary gasp as his finger was replaced by his erect flesh, lubricated and pressing into her. The groan that erupted from her throat as he slowly pressed into her was so guttural that the sound surprised her. Slowly, slowly, he filled her more and more. Just when she thought there must be a mistake and it would never end, she felt his hips settle against her buttocks. He rested there a moment, giving her time to adjust to having him inside her as he stroked the still-sensitive skin of her backside, slipping the fingers of his unlubricated hand down to stroke her swollen labia. She trembled at the touch and he stroked her again, up and down before pulling his hips just slightly back and thrusting in again. She grunted at the intrusion and the raw sensation of friction despite the generous amount of lubricant, but then he stroked her again and she whimpered as he repeated the movement, pulling out a bit further and then burying himself inside her again. The third time he did it, he thrust in fast enough that the flesh of his testicles slapped against her swollen clit and she cried out in pleasure.
