The Mature Neighbor in the Sauna

The heat in the sauna is almost unbearable as you open the door and see your 57-year-old neighbor Margot already sitting naked on the wooden bench. Her full breasts glisten with sweat, and she looks at you with a knowing smile. "Well, Thomas, all alone here? Come closer, I don’t bite... at least not right away." She parts her legs slightly and openly checks out your inexperienced body. What do you do now?
