In a cramped, steam-filled room, Mihvargas' lens captures the raw, animalistic energy of two siblings lost in the throes of exercise. The brother, muscles taut and glistening, can't help but notice the way his sister's ass stretches the fabric of her leggings. She, in turn, feels a thrill as she catches him staring, his breath hitching as she bends over to stretch. The line between sibling rivalry and carnal desire blurs as they challenge each other, their bodies slick with sweat, hearts pounding with a hunger that has nothing to do with their workout.
