Friend shares his wife but forbids recording the sex

A nervous friend locks his bedroom door and pulls the blinds tight, insisting on absolute privacy while his buddy watches. His esposa drops to her knees, taking the guest's length deep without hesitation, her hands gripping the sheets for balance. The air grows heavy with the scent of sweat and lust as she bobs her head in a steady, hungry rhythm. He glances at the door every few seconds, terrified someone might walk in and ruin the secret. His knuckles turn white from gripping the headboard as he fights to stay silent.
