He put his hands on her back and began his deep muscle massage routine he had developed for her. She whimpered and moaned and cooed under his strong hands and his cock got harder and more sensitive the more he touched the woman's body. He had to sweep her ass length wavy brown hair from side to side so he could work unimpeded as he crossed her back. The ends of her hair tickled across her ass cheeks and she trembled with need. It had been a long time since she'd felt an intimate sexual touch of a man. The drugs in her system blunted the fact that the man touching her was related to her.

The pain shot through her again from her upper shoulders. She'd been struck in the spine just between the shoulder blades by a piece of suspended equipment being moved through the factory floor. That had been years before but her body had never recovered. The medical coverage was barely enough to cover the painkillers and she hadn't been able to afford chiropractic care. It wasn't in her health plan.

Ed was massaging on automatic as his sleepy brain dragged him back down. In his mind he was going over the material he'd read on spinal alignment. The body was just another machine to be repaired. He ran his thumbs up both sides of her spine and every time he felt a misalignment he'd push one side or the other or sometimes both. Her spine popped and creaked and Shirley was too stunned to speak. She was terrified at what he was doing but she couldn't speak as the relief after every pop was immense. He reached the point where the main injury had taken place and there was a major misalignment. Before she could even squeak in protest he pressed hard and there was a loud crack. The intensity caused Shirley to pass out. Ed's hands continued up on autopilot until he was sure every vertebrae was straight. He ran his thumbs back down her spine and everything felt right. His hands were on her ass and suddenly he was kneading them. His cock got harder and harder until it was tenting his baggy shorts badly. He frowned and woke up again realizing he'd pulled Shirley's panties down and he was rubbing her deep in the cleft of her ass. Her hips were rolling and she was moaning.

"What the fuck is that?" she gasped.

"Nothing," he mumbled, looking away.

"You dirty boy! Did you get a boner when you gave me a massage?" she hissed, not able to tear her eyes away.

"I'm sorry. I- I couldn't stop it."

"Take those off!" she said pointing to his shorts.

Ed's eyes shot up to look at her flustered and reddened face which he mistook for anger. He slid his shorts down and his cock bounced free.

Shirley gasped once more when it was exposed and she grabbed it with both hands. Ed gasped.

"You dirty, dirty boy! Getting a boner for your Aunt Shirley!" She was growling angrily but her hands were squeezing and stroking up and down.

Ed leaned back to pull away from her touch but she just started to stroke him faster in her tight grip. The sensations were flooding Ed's mind and he moaned and shuddered as pleasure shot through him.

"You were thinking all kinds of nasty things about your Aunt Shirley weren't you!" she said in a breathy voice, her eyes locked on her hands pumping his cock so quickly now.

"Wait! Some- something's happening... stop, I- oh! I can't hold it-" Ed desperately tried to get Shirley to stop but she just went faster and used one hand to rapidly stroke the top three inches and the head.

"OH FU-" Ed began to yell before Shirley slapped a hand over his mouth.
