Stella loves to stroke a hard cock. That is, just so she can punish it so very hard it regrets ever swelling up. She grips and twists and punches her slave's dick and balls and gives him some brisk whacks with her riding crop to further punish the tip. Her long legs are perfect for bringing some painful kicks to his junk and he winces in pain as she delights herself in his suffering. She's hoping to punish his balls until they shrivel up and fall off, just in time for her to decorate her xmas tree for the season.
