In this raw workshop clip, Kari Byron—Mythbusters' fiery redhead bombshell with her athletic-curvy build, perky C-cup tits straining under a gray sweater—delivers prime celebrity butt action. She's down low on all fours over a white workbench, denim jeans yanked tight across her thick, juicy ass cheeks that scream 'grab me.' The real star? That deep, exposed butt crack peeking out, pale skin contrasting the dark blue jeans riding low, with a skimpy black thong strap wedged right in the cleft, hinting at her tight pink pucker and shaved slit begging for attention. Her hips sway slutty as she tinkers with tools, oblivious or teasing, freckled back arching to push that phat rump higher. Long ginger locks cascade down, framing her focused face turning back with a smirk. No pounding or dripping here, just pure voyeur gold: Kari's 36-inch hips flexing, cheeks jiggling subtly with each shift, thong disappearing into her crack like it's made for worship. Industrial backdrop amps the dirty realism—concrete floors, scattered gear—turning a simple bend-over into throbbing ass fetish fuel. Her sneakers plant wide, legs toned from squats, emphasizing those fertile curves that make you wanna rip those jeans down and dive in tongue-first. Edgy, unscripted celebrity tease at its finest.
