She walks towards you. You allow a slight smile to cross your lips and reach out for the next button on her shirt. She pulls back slightly, saying, "Not so fast."

You respond, "But I won the bet."

She nods and says, "Yes, but I have a idea I think you might like. Here, we remain team players. But out of work, it's all 1-on-1. To start, meet me at my place tonight at 7. I think I'll make a better game when I have the home-court."

She writes her address on a blank Post-It on your desk. "In case you need another reason to make the trip," she adds, "you can be returning these." She reaches under her miniskirt, slides her black panties to the ground and steps out of them. She picks them up and lays them across your outstretched hands, before she turns and leaves.
