Part IV - Sam's First Kick

"Ok girls, you heard him!" smiled Jess. "Let's get warmed up with some stretches. " With that, she grabbed Sam's arm and pulled him over to the back right corner of the room. "Lose those," she said, pointing at his boxers.

Sam was in a trance, too enamored with the three gorgeous, now topless, young women to resist. He would have done whatever Jess, Madi, or Danielle asked him to. He pulled off his underwear and revealed his slightly above average sized cock at half-mast. He had planned to masturbate last night but after his encounter with Jess at the gym, he decided to save up for her as he sometimes got 'performance anxiety'. After 2 seconds of thinking about how horny he was and seeing three sleek, fit girls in front of him, he was fully erect.

"I like this one," smirked Danielle. "He's already hard for us. I have a feeling he'll do whatever we say."

"Yeah, good job bringing this one home, Jess," added Madi. "Seems perfect so far. I just hope his balls can take more than the last guy you invited over."

Before Sam could process what the girls had said, Jess swung her bare foot upward into Sam's balls. Sam let out a small 'oof' and bent forward a little. One hand traveled to his balls and he looked up to see all three girls waiting to see his reaction. The kick had obviously hurt, more than a little, but he was definitely ok. He guessed his horniness had somehow diminished the pain.

"Wow, not too bad!" exclaimed Danielle, with her palms facing the ceiling and a slight shrug. "Still standing, which is more than that other guy. What was his name?"

"I don't remember. He was pathetic and his balls were pathetic, too. I can't believe he went home halfway through our session!" replied Madi.

"His name was James. But you're right, let's not talk about that loser. Especially with a new potential pet right here," Jess said as she gestured to Sam.

Part V - Warming Up

"Let's begin our stretching routine. We don't want to get injured. Who wants Sam first? Danielle?"

"Deal," replied Danielle. She walked over to Sam while the other two girls began stretching out on their own. She seductively pulled Sam to the floor with her and for the next three or four minutes, proceeded to stretch with her partner. No matter what kind of stretch, she found a way to press one or both of her tiny bare feet firmly against Sam's exposed ball sack, pressing his increasingly tender orbs into his pelvis, or the floor. It was warm in the room and his balls were hanging as loose as they ever had. Sam remained hard the entire time. Danielle was so beautiful that he relished any physical contact with her, even if that contact was between her foot and his nuts. "Do you girls want a quick turn before we move on?"

Jess and Madi looked at each other, nodded silently and sat down, facing Sam. Jess placed her right foot on the right half of Sam's ball sack while Madi placed her left foot on the left half. Each girl grabbed the corresponding leg, arched their backs, and leaned back, driving their heels into Sam's defenseless balls. Sam was nearly overcome with the crushing pain but the sight of these two perfect, athletic nineteen-year-old bodies, in sexy poses, made it all ok.

When they were finished stretching, Sam had a moment to reflect. He didn't know why these girls were so into busting balls but he was amazed at how confident and sexy they were. They knew what they wanted and who was he to question it? He was eager to please them, wanted to see them happy, and was proud that he could provide them what they desired. He was amazed that in the last several minutes he had gone from a regular guy excited to score to getting his balls busted, and genuinely liking it. He remembered his reward that was to come, a blowjob from all three girls, and wondered how he could have forgotten, if only for a minute. To him, it proved these girls self-assurance and superiority and he was more than a little envious of it.

Part VI - The First Exercise

"Ok Sam, how are you feeling? Based on the fact that you've been rock hard since we took our tops off, I think you're probably just fine. Anyway, I think we're warmed up, hopefully your balls are too. Ready for the real workout?" asked Jess, with her hands on her hips, chest out. All three girls were visibly excited and Sam didn't want to let them down.

Sam was quick to answer "Yes, Jess." He tried not to stare too long at the girls' boobs but found that task too difficult.

Jess was pleased. The night couldn't have started any more according to plan. "Fantastic. First up, we'll do a little cardio. One of my favorite exercises for core strength and burning fat. High knees. Sam, for this, your job is easy. Just stand here, with your legs nice and spread."

Danielle was first up and took her place directly in front of Sam. She was so close, Sam could smell her perfume, which was subtle and sophisticated. "I'm putting two minutes on the clock," said Jess. As soon as the timer began, Danielle began jogging in place, knees rising to strike Sam's balls in quick succession. She was the shortest of the three, couldn't be more than 5'3" so the top of her kneecaps only made soft contact at their highest point. Without being asked, Sam found himself lowering his body an inch or so to increase the contact, and the pain. Her unrestricted c-cup bosoms bounced joyfully and Sam was hypnotized by the sight.

After the two minutes had ended, Danielle was shining with sweat and visibly out of breath. "Nice work girl!" encouraged Madi, as she switched her places. Madi was a little taller at 5'5" and her knees needed no help reaching Sam's low-hanging sack. Sam felt each knee as they slammed into his balls over and over again. Sam took note of the music coming from the speakers in the corner. It was Taylor Swift's "I Did Something Bad" and Sam realized the entire playlist so far had been powerful female artists "They say I did something bad, then why's it feel so good?" sang Taylor, as Madi continued to knee Sam's jewels.

When her two minutes were up, Sam was just as winded as Madi, but he was determined to keep going. Despite his aching balls, he was more turned on than ever after four minutes of bouncing boobs, not to mention the repeated contact with his genitalia.

Jess now stood in front of him and Sam was a little scared. He was 5'11" and Jess was almost able to look him in the eyes. He guessed 5'9". She took no time getting started, each knee ramming his delicate balls into his pelvis despite Sam being on his tippy toes. 'Most fun I ever had, and I'd do it over and over and over again if I could' serenaded Taylor from the speaker, Jess's knees in perfect rhythm with the beat.

The two minutes were nearing completion, and Sam felt himself, unexpectedly, about to come. It was all too much. The mesmerizingly beautiful girls in the room, the music, the bouncing boobs less than one foot from his face, but most of all knowing that he was offering a service to these lovely ladies that few others could. Despite his best efforts, he couldn't contain himself. Sam exploded all over Jess's yoga pants, and a little on her toned stomach. "I'm sorry," said Sam, looking Jess in the eyes, and in what seemed like slow motion. He heard the timer go off as waves of pleasure and pain continued to confuse his nervous system.
