Once Shawna stuffs you between her soft, muscular ass cheeks, they began to close in on you, the slick, greasy surface enveloping your miniature form like a vice. You were trapped, the pressure mounting once she adjusted her pants and clenches her ass continued to squeeze, the warmth and sweat from her skin seeping into your shrunken body. The world faded into a haze of dark, humid flesh as she prepared to resume her jog, leaving you to endure the relentless grinding of her colossal buttocks.
Her powerful clenching and unclenching motions threaten to render you boneless, your body conforming to the shape of her massive naked cheeks with each successive grind. The friction is unbearable, the constant rubbing of your midsection against her hot, sweat-glistened skin, making your clothes cling to you in a sticky, suffocating embrace.
As Shawna begins to jog, her massive strides send shockwaves through your body, jostling you mercilessly between her straining haunches. The exertion causes her cheeks to contract and relax rhythmically, a relentless massage threatening to grind you into submission. You feel the heat of her body radiating through the fabric of her spandex shorts, and the musky aroma of her sweat fills your senses, overwhelming your olfactory nerves.
Each pounding step Shawna takes causes your guts to churn violently, a nauseating sensation that blends with the sheer discomfort of being squeezed and jiggled by her immense rear end. You can't even summon the strength to protest or beg for mercy, so overwhelmed are you by the jarring, disorienting experience.
Yet, as you're propelled along the jogging track, you can't help but marvel at the sheer force and vitality of Shawna's body, at the raw power that drives her forward with such relentless determination. Her ass, once an object of admiration, has now become a prison, a sweaty, smelly, stifling cocoon that threatens to consume you whole.
As Shawna continues her jog, her pace increases, and you find yourself tossed about like a rag doll, your body battered against the soft yet unyielding flesh of her cheeks. The final sprint brings her to a blindingly fast stop, and you're left gasping for air, your entire being aching from the brutal treatment you've endured.
You already wondered when will she stop...
