until your ass twitches

Description: It’s nearly 40 degrees. The air is shimmering; sweat is already streaming down your back before the first lash even touches you. You’re standing naked, hands above your head, legs slightly spread. Your ass is the only target. I circle you slowly, the long leather whip in my hand. Sweat drips from my tits, the latex clings to my skin, and I smile coldly. "Today, your ass gets whipped until it twitches. Until every muscle spasms on its own and you can’t hold still anymore." The first lash cracks. Hard. Right across your right cheek. You flinch slightly. Second lash. Left cheek. Third. Fourth. Fifth. The heat makes it all worse. Your skin burns twice as intensely; sweat mingles with the first thin trickles od sweat.  I keep whipping—rhythmic, merciless. The whip whistles through the hot air, striking true every time. Your ass turns dark red. Welts rise up. You start to tremble. I pause briefly, touching your burning flesh, and feel it twitching beneath my fingers. "Not enough yet. Keep going." I switch to the thinner switch. Faster strikes. More precise hits. Over and over on the same spot, until you cry out loud. Your ass is twitching uncontrollably now. With every new lash, it spasms instinctively—as if trying to dodge the pain—only to take the next blow even harder. I only stop when your ass keeps twitching, even though the whipping has long since ended.
