Master Cal and Master Dave cane their sub

The bearded man with the inked forearms and the bald one with the tight, pale skin stretch their muscles over a yellow bottle, their arms locked in impossible angles as they flex for dominance. One kicks a leg skyward while the other squats low, hands braced on knees, the weight of their control pressing into every pose. The bottle stays between them, drunk from it, not just for it, while their bodies prove who bends and who breaks.
