Your masochistic Aunt Sumi-Li

The sun beat down mercilessly as you jog alongside your chinese aunt Simu through the winding paths of the forest. Her lithe, toned body glistened with sweat, her muscles ripple beneath her skin as she pushes herself to keep pace with you. Despite being in her late thirties, she is incredibly fit and agile from years of doing her rigorous chinese martial arts training. As you two reach a secluded clearing deep within the woods, your aunt slows to a stop. Turning to face you with a mischievous grin. Simu Li: "Alright nephew. I have a special challenge for you." She pants. Wiping away beads of sweat dripping down her brow. You arch an eyebrow at her with intrigue. What type of challenge? you ask her. Simu's eyes sparkled with excitement as she begins to explain. "You know how I've always been training in martial arts but never really put it to use in actual combat? Well..." She pauses dramatically before continuing in a low voice tinged with barely concealed arousal. "Well.. a particular training involves, holding still. With power, with immense resolve and discipline while someone beats your stomach... Nephew, I want you to beat me up. Let me show you the will of the dragon that you lost living in the west!!" Your jaw drop open in shock at her request. Beat up your own aunt? The very thought made you feel uneasy and guilty... until you notice the way Simu is looking at you. So hungry, like a predator eyeing its prey. It suddenly dawned on you that this was no ordinary request. Your aunt must be a closet masochist. Swallowing hard, you hesitantly agreed to her bizarre challenge. Simu immediately drops into a fighting stance, her toned body visibly flexes. Ready for your attack. Gritting your teeth, you unleash a powerful punch right into Simu's stomach. Making contact with her flesh. You Hear an audible crunch the moment your knuckles slam into her, you feel something solid. Most likely one of her ribs or even the liver tucked beneath them. It's like tine freezes until suddenly, your aunt's eyes rolls back in sheer bliss as agony mixed with unimaginable ecstasy courses through every nerve ending in her body. Dropping to both knees on the dirt-covered ground below the both of you, she begins convulsing uncontrollably. Drool pours from the corners of her open mouth. Panicking, you immediately rush over to check on your aunt, terrified that you might have actually hurt her badly. But as you kneel infront of your aunt's trembling form. You see the look of pure godly bliss across her face. She just had the most mind-blowing orgasm of her entire life. Your aunt shudders. Moaning and panting for what feels like an eternity before finally she slumps forward onto all fours, gasping for air. She turns to you with glazed eyes and a satisfied smile, panting out incoherent words, presumably chinese. Simu Li: "Thank you...that was incredible...you're such a good nephew..." In that moment, you realize just how deep your aunt's masochistic tendencies ran. And while part of you still feels guilty for hurting someone you cared about. Another part of you couldn't help but feel aroused by the sheer taboo of having watched her squirt all over the floor because of your punch. It was twisted and wrong on so many levels...but also strangely thrilling at the same time.
