The Pavlov Cupid's Plan - Part 4 Alt ending

It had been a few months since Katie gave him such a brutal lesson. Mandi was cleaning the apartment when a notebook fell open on the floor. She picked it up, and a stick drawing of a man astride a balance beam immediately reminded her of her boyfriend's accident. Puzzled, she opened it and began to read through it, it was titled "The Pavlov's Plan". Her eyes narrowed with growing anger as she discovered how he had manipulated her into falling for him.

*Pavlov? What am I? A dog!* she thought, her heart pounding. It was even more annoying because it had worked. Still, she was kinda impressed with how he had put his balls on the line like that. Her breath quickened as she remembered the pain etched on his face. He clearly deserved a good lesson.

All her life, her kindness had stopped her from acting on her desires, but not this time. She would turn the tables on him and do her own Pavlov's plan. She would engineer accidents where he hurt his balls, then comfort him and give him an orgasm, until he was conditioned to associate ball pain with pleasure.

For the first one, she took great care to make it look accidental. They were fooling around in bed, and she positioned herself just right. She fell on him knee first, striking him squarely between the legs.

“THUD!”

“AAAHH! MY BALLS!” he cried, doubling over in pain.

“Oh my God, I’m so sorry!” she exclaimed, her voice full of pretend concern. She helped him lie back, her hands gently massaging his balls. “Let me make it better,” she whispered, lowering her head and taking him into her mouth. She massaged his balls while she blew him, soothing the pain with her touch.

The second accident happened a few days later. They were in the garden, and she “accidentally” walked on a rake, sending the handle flying between his legs.

“THUD!”

“AAAGH! MY BALLS!” he groaned, clutching himself.

“Oh no, I’m so clumsy! Let me help,” she said, guiding him to a chair. She massaged his balls again, her fingers gentle and soothing, and then went down on him, blowing him until he came, the pain mixing with pleasure.

She repeated this as frequently as she could, making the accidents as believable as possible. Her sweet girl image helped pull it off. Each time, she apologized profusely, comforted him, and then blew him, reinforcing the association between ball pain and pleasure.

After a few weeks, she noticed the plan was working. He was now getting hard immediately whenever his nuts got hurt. During movie night, she selected a film with lots of ballbusting scenes and watched with satisfaction as he seemed even more excited than she was.

She reached over and grabbed his testicles, her fingers curling around them possessively. “So, the Pavlov's plan, huh?” she said, her voice low.

He looked at her, his eyes wide with a mix of fear and arousal as he realized she knew. “What? ...It's not what it looks...”

“Shh,” she whispered, squeezing gently. “I know all about it.”

“It’s funny,” Mandi continued, her fingers still gently but firmly gripping his balls, “I’ve also been training you a bit. Have you noticed how hard you are when your nuts get hurt?”

His eyes widened in realization. “You’ve been...”

“Yes,” she said with a smirk. “You're addicted to ballbusting now. And no more blow jobs for you. I’m going to blue ball you until you beg me to bust your nuts.”

She began to massage his balls roughly, the pain making him harder than ever. Her hands moved with a practiced rhythm, alternating between gentle caresses and harsh squeezes, keeping him constantly on the edge. His breathing quickened, his body trembling with a mix of pain and arousal.

“Please... Mandi...” he gasped, but she only smirked, continuing her relentless stimulation.

She edged him for what felt like an eternity, bringing him to the brink of orgasm before pulling back, then starting again. His balls throbbed with pain, his cock straining with need. Each time she stopped, he whimpered, the frustration and agony driving him closer to the edge.

“Please... I can’t take it anymore...” he begged, his voice hoarse.

“What do you want?” she asked, her voice sweet but commanding.

“Kick my balls... please... I need it...” he finally caved, his voice desperate.

Mandi smiled, her eyes gleaming with satisfaction. “As you wish.”

She stepped back and delivered a full-force kick right to the center of his testicles.

“THUD!”

“AAAGHH! MY BALLS!” he screamed, collapsing to the floor, writhing in agony.

The sight of him in such pain and the exhilaration of finally fulfilling her taboo fetish sent waves of pleasure through her body. She moaned loudly, her body convulsing with the most intense orgasm she had ever experienced.

As she stood over him, panting and flushed, she knew their dynamics had changed forever. She looked down at him, her breath still ragged. “Now, we both got what we wanted,” she said softly.
