Suddenly, the bedroom door swung open, revealing her husband.Our eyes widened in shock as we froze mid-motion."What's going on here?" he asked suspiciously, taking in the sight of his wife's exposed body and his step-son's erection pressed against her ass.Embarrassed and aroused Embarrassed and aroused, he turned away from the incestuous scene unfolding before him.
