As Tracey followed her instructions, Sara groaned as the finger's curved inside of her. She was glad Tracey could follow instructions and seemed to have a knack for this for one that has never done it before. "Yes...like that...bloody hell..."
Stretching her fingers out first, she then balled them in to fists against the table as Tracey continued her work. She could feel her orgasm nearing. After a few moments, she let her head fall back as she gave a lustful, loud moan as she came.
Sara remained still for a few moments while she recovered from her orgasm. Eventually, she spoke, "Damn, I'll have to keep you around if you keep working that good." she joked. She did plan on keeping Tracey around, she was good at satisfying Sara, at least until she got bored.
