Unbuttoning her shirt, Sierra sucks his cock and rides him from behind

On a tan couch, Sierra opens her white shirt and pulls her black bra aside to stroke his shaft against her tits. She bends forward and wraps her lips around him, letting spit run down her chin and drip onto her chest. Then she turns, flips up her plaid skirt and pulls her ass cheeks apart to guide him in from behind. Her fingers dig into her own ass as she rocks back onto him, the whole length sinking out of sight while she grins.
