More "proof"

Mr. Thick lifts Kathy off of his cock and spins her around. Your mom is now bent over the side of the hot tub, and facing the house. You're afraid she might see you recording evidence of her infidelity, but the sight of her massive breasts hanging over the edge of the hot tub is definitely worth the risk.

Mr. Thick slowly enters your mom's asshole with his monster cock. You see the look of pain on your mom's face. In a mixture of pain and pleasure, Mr. Thick is tearing Kathy's ass wide open. Mr. Thick is only a few inches into your mom, when he starts to pull out. Your mom looks relived when Mr. Thick was out of her. Unfortunately for your mom, Mr. Thick had other plans, he stuck his black cock back inside her butt, this time he went a little farther and a lot faster. Your mom cried out in pain. This only turned Mr. Thick on more. He speeds up his thrusts. Your mom's tits are flailing around as her ass is violated. Tears are streaming down her face as Mr. Thick pounds her ass. For several minutes the hardcore ass fucking continues. Kathy's hot body is trembling. Finally Mr. Thick pulls out and spins your mom around again. He forces her to sit down on the hot tub as he strokes himself right in front of Kathy's face. You zoom in on your mother's face as Mr. Thick covers your mom in cum. His semen completely coats her face.

The two lovers get out of the tub and walk into the house. You have some seriously good action on tape.
