She is still convincing you

You rub her shoulders, she gets up and unzips her skirt as it gets thrown behind your desk, you can see her perfectly tanned legs leading to her lacy black thong. She gives you a kiss as you move your hands along her petite body.

She then turns around as her ass is grinding along your crotch. She leads your hand past her navel toward her pussy. You slowly start to finger her.

She then says, "I want to be you protege and I will do anything you want. And I am really bad bad girl."

Just then you hear a knock it is Sheena, she races under your desk and you sit at your desk. She takes a seat begins talking to you about internship, while Becky starts to lick your balls while her hands jerking your shaft while under your desk. You already hard and with Sheena couple feet from you.
