Lunchtime seduction

A man and a woman meet in Costas for lunch. He arrives first and chooses a table, securing it with his suit jacket slung over the seat back. He joins the queue. She arrives, he directs her to their table. She has brought in a sandwich from Pret a Manger. She takes off her jacket and sits down. He brings over hot drinks and moves his chair closer than 180 degrees around the table. They talk. He seems keen. He reaches out a hand and strokes her thigh under the table, comments on her dress, moves his knee into a position where she will feel his heat through their clothing. She doesn't touch him at all. She seems contained. She puts her hands together in her lap. He looks into her eyes while they talk, taking large bites of his sandwich. And all too soon it is time to leave and get back to work. She brushes crumbs from his trouser leg before they get up. And then they go.
