Silver-haired curves spill over black lace as she kneels on rough gravel, ass presented for the taking. Thick thighs tremble when he grips her hips and sinks in deep, each thrust sending pebbles skittering under her knees. Flipped onto her back on a scratchy blanket, she locks ankles behind his back and pulls him in deeper, belly rising with every raw pump. Mascara streaks her cheeks as she gasps between clenched teeth, fingers digging into his forearms. The river rushes behind them, drowning out her needy whimpers until her entire body tenses and she arches into the final thrust.
