Bianca, on her hands and knees, takes David's thick cock from behind, her ass sticking out invitingly. She pushes back, driving him deeper into her throat, feeling his pulsing manhood against her tongue. David's grunts grow louder, his thighs tense, and Bianca knows he's close. She readies herself, eyes watering, as he pulls out and erupts, coating her face in warm, sticky cum.
