Sarah needs it

Another AI story. It's odd, because I asked for kneeing in the prompt, but it's still pretty good.

Sarah was feeling horny again. She didn’t need any particular reason to be turned on, it was just a constant state for her. She was walking around her apartment, her tight pussy already getting wet. She couldn’t wear underwear or bras anymore, they just got in the way and made her even hornier.

She was looking around for something to do, when she saw her neighbor Rob through the window. He was mowing his lawn, shirtless and sweaty. He looked so hot, Sarah felt her pussy get even wetter. She wanted him, but she couldn’t just ask him for sex. She had to be more creative than that.

Sarah walked over to her door and opened it, sticking her head out. “Hey Rob,” she called out. He turned off his mower and walked over to her.

“Hey Sarah,” he said, smiling at her. “What’s up?”

“I was just wondering if you wanted to come in and help me with something,” she said, biting her lip.

Rob raised an eyebrow. “Help you with something? What do you need help with?”

Sarah smiled. “I’ll show you.” She stepped back and let him in, closing the door behind him. She led him over to her couch and sat down, patting the seat next to her.

Rob sat down, looking at her curiously. Sarah looked him straight in the eyes and reached down, grabbing his balls through his shorts.

Rob gasped, his eyes going wide. Sarah smirked, squeezing them gently. “I need you to do something for me, Rob,” she said, her voice low and husky.

“What do you need me to do?” he asked, his voice shaking a little.

Sarah leaned in closer, her breath hot on his ear. “I need you to let me hit your balls,” she whispered.

Rob’s eyes went even wider, if that was possible. “What?” he asked, his voice barely above a whisper.

Sarah squeezed his balls again, a little harder this time. “You heard me,” she said, her voice firm. “I need to hit your balls. It’s the only way I can orgasm.”

Rob looked at her for a long moment, his eyes searching hers. Then he nodded, his voice barely above a whisper. “Okay,” he said.

Sarah smiled, her pussy getting even wetter. She stood up, pulling her shorts down and stepping out of them. She wasn’t wearing any underwear, and her pussy was already glistening with wetness.

She stood in front of Rob, her legs spread wide. She looked him straight in the eyes, her hand still wrapped around his balls. “Are you ready?” she asked, her voice low and husky.

Rob nodded, his eyes locked on hers. Sarah smiled, then she raised her closed fist and brought it down hard on his balls.

Rob gasped, his eyes going wide. Sarah smirked, then she did it again, and again. Each time, she hit his balls a little harder, a little faster. She could see the pain in his eyes, but she didn’t care. She was too horny, too close to orgasm.

She kept hitting his balls, her pussy getting wetter and wetter. She could feel her orgasm building, her muscles tensing. She was so close, so fucking close.

Then she hit his balls one last time, and she came. She threw her head back and moaned, her pussy clenching and releasing. She could feel the orgasm spreading through her body, making her legs shake and her breath catch.

When it was over, she opened her eyes and looked at Rob. He was still sitting there, his eyes wide and his mouth open. She could see the pain in his eyes, but she didn’t care. She had gotten what she needed, and that was all that mattered.

Sarah smiled, then she leaned down and kissed him. She could taste the pain and the sweat on his lips, and it only made her hornier. She knew she would need to hit his balls again soon, but for now, she was satisfied.

She stood up, pulling away from him. “Thanks, Rob,” she said, “I needed that.”

Then she turned and walked away, leaving him sitting there, his balls throbbing and his mind blown. He had never experienced anything like that before, and he wasn’t sure if he ever would again. But one thing was for sure, Sarah was one horny girl, and he was glad he could help her out.
