Again, sorry for letting you wait so long. I guess I should publish the prior parts only when my drafts are already at least halfway through. Apart from that I hope you mind this finale of a series I really enjoyed writing. Have fun!

As her knee reached my balls, she pushed me down by my shoulders, increasing the damage I felt to a new extreme, but there was no time to fall down, let alone comprehend the pain, as the next knee followed shortly after.

My nuts felt like they were pulverized, reduced to pieces. I bent over in shock, pain and terror, but before my hands could reach my nuts to check and protect my precious manhood, Julia grabbed my wrist, took a step backwards and swung her leg like a whip, connecting her foot perfectly with my balls.
I jumped up a bit as the smack occurred, giving her the opportunity to press my arm against the wall, making me tremble a bit backwards and rushing her hard knee right into my genitals again two times. Julia didn't just see this as a playful power play anymore, but a competitive sport and she's giving it all to be the best in it.

She switched from bone crushing knees to whip like kicks, used every opportunity when I was about to fall to grab my balls or push me against the wall again to continue her devilish work. Well, but as the pauses became shorter and shorter, my tolerance became as well.
My dick really wanted this to continue, loving the brutal attention my nuts were getting, but my body got in between as my legs trembled after a just so devastating knee, clearly meant to floor me without resistance and to my surprise she didn't punish it.
I don't know how she did it, but Julia was a natural expert, knowing very well when to strike, but also when to stop.

My body fell like a sack of potatoes and I got down on all my fours again, my arms shaking as I tried my best to fight against the pain without any usage.
"Sit down, Dan and lean against the wall!" She demanded, but in a strangely soft tone. I obviously did like demanded.
"Now spread your legs." Her voice was nearly shaking. What the hell was she up to? I slowly spread them apart, leaving my beaten up balls, which were laying on the hard floor, as well as my steel hard rod, which was dripping pre-cum like I'd never see it before.
As her foot slowly made its way to her area, I anticipated a brutal stomps, her toes grinding my balls into the wooden floor, but I got even more shocked as those toes weren't used to batter my family jewels, put for stroking my erected dick that was desperately waiting just for this heavenly treatment with the warmth of her foot as well as the soft fabric of her dark pantyhose.

It wouldn't be more than 30 seconds for the biggest load of my life to leave my battered, aching balls, but it wouldn't be Julia, my crazy best friend, if it wasn't for a cruel, yet viciously hot plan. She put her foot back in place, putting me out of my trance like status.

"I have to say, it was incredibly fun today and I really want to give you a worthy reward given how much your poor little balls had to endure." She mustered my face, every fiber of it screaming how much I want her to continue with this.
"There's just one thing: You're here for me to beat up your balls and I believe I have a just so perfect plan to end this session on a note that will satisfy both of us greatly." And with that she walked away.

God damn it, what is she going to do? I was just sitting there for the next two minutes, just waiting for her to come back and finish her job. Every second felt like too much and my dick twitched like nothing else. Then I heard her footsteps. I got happy. Finally, I just thought, but as I realized that the steps that were getting closer sounded a lot different, shivers went down my spine.

A second later that fear stepped into the scene in the form of a brutal looking pair of Doc Marten's.

It felt like a demon was walking towards me, her smile wider than I've ever seen it before. I put my hands, shaking in fear, away from my crotch as her steps came nearer and nearer. She finally stopped and instantly laid her booted foot right on my balls, slightly adding pressure.
"Now Dan, when you truly want to cum, then jerk off." And without any other words, she brought her foot back up and jerked it down again, grinding it hard into the floor.

I screamed in agony at the first hit in minutes, but I didn't get any time to think about the pain. I put my rod in my hand, beginning to stroke it in a rapid pace as she continued to flatten my balls under her brutal shoes and her strong, wonderful legs.
I just had one single thought in mind: Cum as fast as possible.

It didn't take long for me till I knew that the point of no return was just around the corner. My breath became heavier, sweat was running down my whole body. Only seconds, I thought, only seconds and I'm finished, but that relief was short lived, cause Julia noticed as well and she wouldn't let me get out of this so easily.

Without any hesitation, she stomped down again, me letting out the most blood curdling scream imaginable. She laughed as I suddenly stopped my hand movement, switched from her sole to her heel and bounced it up and down like they were a gas pedal, sending jolts of pain every splint of a second.

Even the slightest hand movement was hard to manage, it felt like I was barely able to breath as my most sensitive parts got pounded into the ground. My body was dedicated, dedicated to end this pain, even when it takes every resource of my body.
I grabbed my cock like never before, basically strangling it and jerked it in a pace I didn't know I was capable of. My face was strained with dedication and agony, my hand convulsively going up and down my twitching cock and as her heel landed one final time on my flattened orbs, it happened.

The biggest load I've ever seen came out of my strangled cock like a fountain, spreading my cum all over the floor, my own legs and especially her black doc martens, now sprinkled all over with white stains. She slowly put her foot away, laughing almost silently. I just sighed, both out of incredibly exhaustion, as well as incredible relief.
