Follow her to the park

They meet at the park at lunch time.
She is finishing a sandwich when he arrives.
She is reclined on the grass, wearing tight jeans that define her legs and the roundness of her butt.

John says: "No skirt today?"

She sits on his lap, embracing him with her legs, caressing his shoulders and kissing him passionately.
He puts his hands under her top and fondles her tits.
Some students walk by and notice it.
