A secret ballbusting party of course

Cindy told you there were only 2 conditions to being let into the party, being invited and bringing a naked boy.

The choice of partner was obvious, and actually the only you had so that afternoon you call Zack to tell him he had to go with you to Cindy's party. He immediately realized it was not going to be the kind of party he was going to enjoy and said no. You don't even bother to argue and instead talk to Ms Andrews the next day.

In front of the entire class you tell her that you are going to need to have sessions with Zack everyday this week. She lifts and eyebrow but the new regulations are clear so she says yes.

That day you take Zach's punishment to a whole different level. While you attack his gonads ferociously he begins to be really scared you were going to literally break his balls.

Even though you don't bring up the previous day's call at all, he knows why he is being punished and what he needs to do to save him manhood.

After a particularly hard snapping kick he manages to mumble something. You get very close to his hunched down form and with your ears almost on his mouth you casually lift his swollen nuts in your palm.

-"Did you say anything?"

-"I'll go but please stop!". He whispers with whatever little air he has.

With a beaming smile you answered -"Great. Thank you! We can go back to class then."

While you both walk back to the classroom, he has plenty of time to reflect on his new circumstances while he limps behind you, butt naked in front of the entire school and with his testicles squeezed within your fist.

That Saturday you are ready by 8pm, your family is super happy to see you are making new friends in this town and are not a shy loner anymore so they give you a pass on the a little to sexy outfit you chose. It is just a small back dress, skin tight and very short and high heels. The weather is warm so no coat is needed. What they don't know is that you exchange your underwear for a tiny two piece swimsuit you just bought in case the jacuzzi Cindy mentioned is being used.

Zach arrived precisely in time and looking great. He was the perfect gentleman, holding the door for you and all. It's amazing what a good ballbusting session does for a guy's manners.

When you get to Cindy's place there are some cars parked outside a music can be heard. You ring the bell and Jake opens the door completely naked. He points to a sideroom where there is space for the boys to leave their clothes. You wait while Zack obediently gets it all off and the you both go together into the living room, where most people are. You are a little apprehensive on how the rest of the girls are going to receive you but only find smiles and nods, especially when they eye the great looking naked boy you brought.

Zack feels all eyes on him but knows better than to cover himself so with his big balls swinging he was deeper into the room, always respectfully behind Zoe.

A few girls you know are part of the cheer leading team call you over and invite you to sit with them. Zack takes his cue from the companions of those girls (all in the football players) and stands close to you.

Cindy sees you from across the room and comes to greet you with a welcoming smile.

Cindy: "It's great you could come, and bringing Zack. Several of the girls wanted to have moment with him".

Zoey without thinking replies "Thanks for inviting me" and immediately hates herself for it. It makes her sound like someone who is not usually invited to the parties the popular girls organize, which it's exactly what she is.

Cindy: "Sure! We are a small sisterhood and you are part of it now. And now let me properly welcome Zack here." And without hesitation she stands in front of him, putting her left hand on his right shoulder, almost as if she were about to lean in a kiss his cheek but instead lifts her right knee with feminine grace all the way up between his thighs. When his face contorts with pain she smiles and extricates her knee from his nuts.

Suddenly all the other girls stand and form a queue to say hello to the obnoxious new guy. They are all very fit ranging from slender to more muscular but none beyond fitness model size. The last 2 come from the Jacuzzi judging by their very cheeky bikinis. You congratulate yourself on your choice of undergarment and for buying your first thong bikini for this occasion.

Zack takes it without protest, as one by one the girls introduce her knees to his testicles. The last girl, a petite black girl with a gravity defying butt asks you "He was rude to me on his first day. Can I have him for a while?" And before you answer she adds "You can have my boy Darius." The boy you are being offered was a huge black guy. He was very muscular, 6 feet 5' and with an impressive equipment. You are **** but you want to be accepted so you say yes.

The girl, Tanisha, invites you -"Come on, follow us to a quieter place and have some fun. You both follow her and Darius to an adjacent room that looks like a reading room where all furniture has been moved aside. You switch partners and Tanisha gets to work on Zack immediately. You watch them for a minute, trying to learn from the more experienced girl. She has more muscles than you and compensates her short stature with great flexibility reaching the taller Zack's groin easily.

You then square off in front of Darius and hesitate for a moment. You have never seen a black boy naked before much less hit him in the groin. Actually Zack is the first boy you ever hit down there and what a start, a naked guy with an awesome body but Darius is a bit intimidating with his size and the gargantuan penis and testicles hanging exposed.

Tanishe sees your hesitation and suggest "Star with him at your own level" and changing her tone from friendly to commanding she orders "On your knees Darius and stay there until she tells you otherwise".

The big guy complies without hesitation and suddenly he is down to his knees keeping them well spread and at about your same height.

You decide he is docile enough and to make a good impression on Tanisha go against him without reservations.

Your white foot collides with his solid black balls a full speed making them jump around in all directions. They not only look huge but on your foot you can also feel their size and mass. You concentrate on his face and let your foot tell you if you were accurate or not. You fail you third blow but correct your aim and send several more. When you feel confident enough you order him to stand up, what he does with slight difficulty.

Once he is towering over you, you try a knee but due to the height difference you barely graze the bottom of his full sac. Reaching him should be possible, after all Tanisha who has the same height difference with Zack is landing very solid knees with ease. You promise yourself to work on your flexibility and change to something you've been wanting to try.

Darius is hating the humiliation of being passed around as if he were Tanisha's **** but in this changed world he pretty much is so he knew he had to do as she pleases. The white girl seemed a soft nerd and had a so much less powerfully built body than Tanisha that he wasn't expecting the pain she was dishing out but much less was he expecting what she did next.

You take off your dress over your head and wrapped it around Darius waist as if it were a belt, then push his huge dick up and under it keeping it pointing up and out of the way.

Feeling her cool hand firmly grasping his dick and manipulating it sent a shiver of pleasure through Darius body that along with seeing the very small bikini she was now wearing caused him to start building an erection but before it got too stiff her first blow landed.

Zack also caught her while removing her dress and open his eyes as saucers when he found out her bikini was closer to a g-string than a thong. This however lasted only a second before he was rudely brought back to his present predicament when the magnificent fitness girl that temporarily owned him gave him a particularly good knee.

You, as soon as you get his penis out of the way look down to get an unobstructed view of his scrotum and liked what you see. It looks like a smaller (but not too much) version of the speed bag you had seen boxers in movies using for training. This is exactly what you had in mind.

Your right fist hits his right testicle which is as large as her closed hand. Without giving him respite you sent your left fist against his left testicle. The you start aiming for the center at the point where they touch each other. Your rhythm is steady and as fast as you can without loosing precision but roughly, as soon as his nuts swing back down and to the front, your next punch lands sending them flying backwards. The solid meatballs of his manhood receive your bony fist's punishment over and over.

The accumulation of pain is breaking his resistance and his knees slowly start to give. When his low hanging sac is to low for you to punch it straight you turn to uppercuts what makes him go up again. This feels different and fascinating. Hitting his nuts is easy but trapping them against his body which causes the greatest effect is much harder so you open your hands to have a larger surface and continue with upward slaps. You soon discover slaps are far better from this angle, and the clear feeling of him flattening orbs feels delicious in your hand.

Nest to you Tanisha is giving Zack the beating of his life.

After 20 minutes you all go back to the living room to get something to drink. All girls laugh when they see how slowly and carefully the boys take each step.
