"Enter" she whispers, her voice barely audible over the birdsong. He obliges, his hard cock pressing against her entrance, seeking entry. She gasps as he fills her, their bodies entwined like the roots of the ancient tree they lean against.

The outdoors becomes their playground, their canvas, their taboo.
