He fucks her doggy style against a tree

John strode over and grabbed her by the arm—eliciting a horny squeal—then spun her around. Pushing her near a tree, he ordered, “Bend over.”

She obeyed instantly, bending low so that her pert ass was raised toward him, soaking panties on display. She braced her hands against the trunk, and looked back at him, eyes alight with eagerness. “I’m all yours, sir,” she moaned.

He took his engorged cock in one hand and thumped it down onto her ass, rubbing himself between her cheeks. She mewled with pleasure, unintentionally twerking on him as she shook with the aftershocks of her orgasm.
