Got a girlfriend but her wet pussy changes everything

A woman in a floral dress and straw hat lounges on a blanket in a grassy field, eating pastry and reading. Her dress rides up as she shifts, exposing her bare thighs and buttocks. A man enters the frame, lifts her skirt, and penetrates her from behind while she remains seated. She moans with eyes closed as he thrusts, her body reacting to the motion.
