A dominant partner leads their submissive, wearing a collar and leash, to the couch. The submissive, a eager slut, opens wide, inviting a massive cock to plunge into her mouth. The dominant partner grips the sub's hair, thrusting in rough, deep strokes, making her gag and drool. Spit and pre-cum mix, dripping down her chin, as she struggles to keep up, her eyes watering with each brutal thrust.
