Caught a guy jerking off and helped him cum

He was in the middle of a crowded park, his huge cock out and being stroked furiously when she caught him. Curious, she walked over and offered to help. He hesitated at first, but the desperation in his eyes was too much for her to resist. She knelt before him and took his cock in her mouth, sucking and stroking him expertly. As he grew harder, she pulled him onto his feet and pushed him against a nearby tree, grinding her pussy against his hard cock. Her eyes wild with lust, she moaned as she began to ride him, taking him deep inside her. The park slowly emptied out as they lost themselves in their forbidden passion, unaware of the world around them. Their bodies collide, skin slapping against skin, as they reach the pinnacle of pleasure. Finally, she climaxes, screaming his name as he follows her over the edge, their ecstasy echoing through the empty room.
