Amazed by his stamina and the most recent monstrous explosion of cum, Lisa’s lust-filled eyes look up at the towering challenger still standing above her. Few have lasted more than 30 minutes with the incredible Stenson Sisters, and even fewer have survived the Double Double Vacuum treatment (that’s two pairs of the softest tits stroking the cock while one person sucks the head and the other sucks the balls). Petr, however, is not just anyone. While his latest cum-blast may have left him a little winded, the alpha stud is living up to his status as President of the West Coast Operations (of ISS). His rigorous training sessions with his wife, the infamous Lady Cassandra, have increased his stamina ten-folds, and he was already known for his unending stamina even before they were married. Could the Stenson Sisters ultimately drain this super stud dry and force him to be their sex toy for a week, or would Petr weather through everything they throw at him and make them his bitch?
