"T-to coming..." Spencer breathed erratically, knowing that her professor knew exactly what she was talking about, but knew the woman just wanted to make her say it again.
When Carrow touched her and started the rapid rubbing, Spencer gasped and gripped the woman's shoulders. As the stronger witch held her in place, Spencer met the woman's gaze with just as much intensity, it was clear in her face how turned on she was and how close she was to climaxing. The also showed a great air of submission, as Spencer found herself more and more accepting of her new position with Carrow. Her mouth slightly opened as she breathed raggedly.
At Carrow's questions, Spencer nodded eagerly, too lost in the need to get off to censor herself. Right as she felt herself climaxing, Carrow tore her hand away and Spencer let out a loud whine, whimpering in need. "Professor..." she groaned in disappointment.
