Under the vast, open sky, a bound submissive endures a rigorous BDSM training session. She's secured to a tree, her enormous tits constrained by rope, as her dominant trainer wields an array of implements. He starts with a paddle, the smack echoing through the forest as her ass turns a rosy red. Then, he introduces wax, drizzling it onto her skin, the heat intensifying her pleasure-pain. Finally, he attaches electrodes, sending jolts of electricity coursing through her body, making her writhe and moan.
