Smack!
Ohh.
Slap!
Ohhh.
Bruce continued to slap Barbara's warm pink ass with the leather paddle. He used it as if it were an extension of his own arm. He was obviously well practiced with it. The strikes would come in regular intervals, then the patterns would shift. First one side, then the other. A series of quick light slaps and then a hard whack that pushed her torso forward as she hung there, suspended by the ropes tied round her wrists. She writhed in pain and delight arching her back, standing high on her toes and pressing her back towards him as each blow pushed her forward. Her fingers attempted to find purchase on the ropes, but she quickly found it didn't matter. Whether she held on to them or not, her balance was no longer her own. The bonds held her firmly in place.
She didn't know how long he had been beating her. It seemed like days since she first stepped into the car at the restaurant. The trembling had long since stopped and had been replaced with an intense sensation of pointless resistance. Her body had given in to the experience. She could the heat that had begun to radiate from her waist and ass. She could taste the sweat on her lip as it dripped down her face.
She had considered saying one of the safe words he had given her. "Yellow" would ease the severity of the blows. "Red" would stop the experience immediately. "Oh m- ast-..." was all she was able to say clearly, interspersed between a series of primal sounding grunts and groans and then, the paddling stopped.
She was still blindfolded. She couldn't see what was happening, but she slumped when the respite came. Her hair, now damp, fell into her face. Her breathing began to slow from a series of quick, short gasps to long, deep, nourishing inhalations.
She heard his footsteps as he walked around her.
"My little slave, " he said, "you take your punishment well. That pleases me."
"Th- tha-nk you, " she stuttered. "Thank you."
Bruce began to lightly run his fingertips along her behind. He gently petted and patted her with the palms of his hand. She squirmed slightly. Her beautiful ass was pink and warm to the touch.
