Under the watchful gaze of the night vision camera, Birx slips into bed with Manny, her eyes gleaming with lust. She straddles him, her big tits pressing against his chest as she guides his massive cock into her eager pussy. She rides him, the wet sounds of their lovemaking filling the room. He flips her over, taking her from behind, her ass slapping against his thighs. He reaches around, his fingers finding her clit, making her squirm and moan. She licks her lips, tasting her own juices on his cock. He pulls out, his cock glistening with their combined fluids, and she takes him into her mouth, swallowing his load in a hot, messy cumshot.
