The Training of Dia Zerva, Day Four

Dia starts the day hung from the bamboo rod, arms stretched tight over her head. Her feet barely touch the balance beam below. Every time she shifts, her body sways and the rod bites deeper into her wrists. A man steps in with a thick rubber cock, already hard. He works it straight into her ass without warning, driving upward as she hangs helpless. She gasps, tries to pull away, but there’s nowhere to go. The beam keeps her feet just steady enough for him to pound deeper. He grabs her hips and fucks her harder, each thrust lifting her off the beam for a split second before gravity slams her back down onto his cock. Her black hair swings wild across her face. Sweat drips from her body onto the wood beneath. Every time she tries to steady herself, the rod twists and her shoulders burn. He doesn’t slow down. He uses the motion she can’t control, driving harder until her legs shake and the only sounds in the room are the slap of skin and the creak of bamboo under strain.
