I clicked the green button, and her video window appeared on my laptop. She held up her phone for me to see, switched it to silent, gave it a kiss, and then winked at me as she reached down out of frame. I knew she was putting the phone between her thighs.
She was sitting at her desk at work. I could see her office behind her, the window with a view of trees in the park, and a bookshelf full of binders. She was wearing a white button-up shirt with a camisole on under it, and a black skirt.
Her desk was in a semi-private office near the entrance to the business she worked at. There was a large window next to her door, where she sat facing the hall. Anyone walking in or out had to walk past her office.
I tested our situation immediately by sending her a text. After a second, I didn't hear anything, but I saw her visibly startle and then blush and look at the camera with wide eyes in mock surprise.
"I nearly jumped out of my seat when you did that," she typed in our chat window. "I'm going to have to be careful."
"I'm going to keep you jumping all day," I replied.
True to my word, I would send her a text every fifteen or twenty minutes. She agreed to keep her phone under her skirt, pressed against her clit all day. After awhile, she got pretty good at not reacting so that anyone but me would notice. But I could see the slight stiffening of her posture, or a momentary pause in her typing.
