Ballbusting ensues as a teacher, students, and their family members must sit on each other's laps to fit in a car.

All characters are at least 18 years old.

Part 1

It's tricky to be a straight male while coaching a team full of beautiful high school girls. Their track uniforms cover as much as a sports bra and cheeky panties. It doesn't help that I'm only twenty-five, and most of the girls constantly make jokes about how they want to have my children for my "perfect genes".

On the morning of the biggest track meet of the year, some fucker slashed both our bus's tires and my car's tires. Everyone was forced to find their own ride to the meet.

We have a pair of fraternal twins on the team, Ashley and Layla. Their smokin' hot mom insisted that I ride with them.

The blond twin, Ashley, is the captain of the track team and the cheerleaders. Every guy in the school drools over her much more than anyone. I have to admit, her adorable face, her goddess tits, her plump, round ass- Ashley is female perfection, and she loves showing off. I couldn't count how many times she'd bent over to show off her cleavage or ass, just to have an excuse to nut-kick the first unpopular guy to ogle her.

The other twin, Layla, is just as beautiful, but she goes under the radar for being a quiet, pale goth. I'd say Layla's ass is even better than Ashley's, best butt I've ever seen. She has her violet hair in pigtails, and even wears her goth makeup to meets. Don't know why, but that look has always been a kink of mine.

The only time I'd seen Ashley filled with rage was when popular guys went from staring at her bent over ass, to staring at Layla's ass as she walked by. That was also the only time I'd seen Ashley kick popular guys in the balls, and that was full force. It was one of the rare times I'd seen Layla smile.

I was bewildered to see how many people would have to fit in their car. There was me, the twins, their brother who was in the same grade, and their divorced parents. There would only be three passenger seats available due to needing to put one of the coolers in the middle seat.

I said, "Looks like there's not enough room, so I'll just find another way there."

Ashley smiled deviously and said, "I'll just sit on your lap, Mr. Johnson."

The mom said, "No, that doesn't seem right. If it's okay with you, Mr. Johnson, I could sit on your lap while Ashley drives."

My brain was telling me to just get an Uber, but the mom's voluptuous body in a tank top and short skirt was fucking with me. I said, "Sure, that's fine."

Ashley looked pissed.

The bigger brother, Caleb, said, "To make us all fit, we'll also need to have Layla sit on my lap."

Caleb was kinda like the male version of his sister, Ashley. He loved to harass girls who were hot, but not part of the popular crowd that loved him. He'd grope them and wave his huge cock and balls at them in form-fitting shorts. When unpopular boys would try to stick up for their female friends, popular girls would knee or kick them in the balls. The school dismissed any complaints from teachers and students because Caleb was by far our best athlete.

The mom, Ms. Aubert, asked, "Would you be okay with sitting on Caleb's lap, Layla?"

Layla sighed and said, "Whatever."

Everyone was now in the car except for the mom, Ms. Aubert. Ashley put on a Billie Eilish album and cranked it up. Ms. Aubert bent over to tie her shoe, revealing her plump caramel-tanned butt in a thong. Each cheek was an unblemished absolute unit off round ass.

My cock hardened in my thin cotton shorts. I was in full panic mode as she approached the door. She opened the door and didn't seem to notice my growing bulge. Just before she sat down, I angled my cock to be against my abs.

Her bare cheeks were so full that they landed on both my cock and my balls. I felt such sudden cock-pleasure and nut-pain. The pleasure and pain would not let up as her soft butt formed around my cock and balls. The weight of her wineglass body pressed down, suffocating my manhood.

I saw in the rearview mirror that she had an inquisitive look. To confirm her suspicions, her butt began grinding on my cock and balls. My pleasure and pain amplified. I did everything I could to stifle my groans and my erection.

She looked over her shoulder at me and giggled. My face burned with humiliation.

She whispered in my ear, "Don't worry, it's natural."

I wanted so badly to tell her that her ass was crushing my nuts, but it was too embarrassing.

In the rearview mirror, Ashley smirked at my wincing face. She then feigned an expression of woe to mock mine. By the pained look on my face, that bitch must've known what her mom's big ass was doing to my nuts.

Ashley winked at me, then began the drive by suddenly pressing hard on the gas. This caused her mom's butt to press even harder against my cock and balls. It felt great on my cock as it sunk even deeper between her heavenly cheeks. However, my trapped balls flattened against her cheeks. The crushing pain was unbearable. Ashley stuck her tongue out at my agonized face. That clever cunt knew exactly what she was doing.

Ms. Aubert asked, "What was that, Ashley?"

Ashley said, "Sorry, I haven't driven in a little while, but I'll be fine." That cunt turned onto a bumpy road filled with potholes.

Ms. Aubert said, "It'll take longer going this way."

Ashley said, "Well, we're already here. Might as well keep going."

For the next several minutes, Ashley kept driving erratically with the explanation that she was trying to avoid potholes. She would make hard turns that would cause one of her mom's butt cheeks to put so much pressure on one of my nuts, switching from one nut to the other. She'd keep suddenly breaking hard, then flooring it, all just to keep fucking my nuts with her mom's ass.

The bumpiness of the road often caused her ass to vibrate on my balls, and sometimes bounce on them. The pain in my swelling nuts kept building, echoing into my torso. It was emasculating that a woman's beautiful soft ass was torturing my manhood without her even being aware of it.

While my balls were in hell, my cock was in heaven. It was like her ass was giving me the lap-dance of a lifetime. At some point, all the movements caused my cock to slip through my fly and sink even deeper into Ms. Aubert's cheeks. She seemed to pretend to not notice, probably because she knew it would just be too awkward. My sweaty cock on her dancing sweaty cheeks made the sexuality so much more intense. I would've had such powerful orgasm if it wasn't for my agonizing nut-pain.

Throughout it all, Ashley continued to mock me. She'd imitate my agonized expression in the rearview mirror while reaching down with both hands, most likely clutching her crotch like a man feeling nut-pain. I could do nothing but sit there and keep taking her emasculation.

Part 2

I looked over at Layla and Caleb. Layla was reading a novel called Dead Souls as she looked mildly annoyed at the situation she was in. Caleb had a wide, sinister smile. He was having the time of his life as Layla's ass seemed to only be on his cock, not also hurting his balls. All the erratic driving only added to his pleasure.

Caleb didn't seem to give a fuck that she was his sister since she had the best ass in the world, and it was covered by nothing but skintight cheeky track panties. That fucker often thrust his cock into his sister's cheeks. His evil grin kept getting more and more intense.

I saw that Caleb reached below his waist and began fiddling with something. I briefly leaned over to see past the cooler, and saw that he had taken his massive cock and balls out through the fly of his shorts. He began thrusting harder and faster, his smile looking demonic. Layla's expression didn't seem to change at all.

Caleb whispered, "You should be thanking me for blessing someone like you with this epic cock."

She whispered, "Please, I could barely feel that little noodle. Try harder. I'm bored."

Caleb looked absolutely furious. With his teeth clenched, he whispered, "I know you're just pretending that my massive cock isn't giving you the most intense pounding of your whole loser life, but you won't be able to pretend for much longer."

Caleb began thrusting even harder and faster. Sweat poured from him. Veins bulged in his forehead and neck. He grabbed her by her bare waist to add even more force. Layla continued reading, still only looking like she was mildly annoyed. Caleb saw her face in the rearview mirror, which caused him to look shocked.

Caleb decided to change his target. He leaned Layla forward and began thrusting at her womanhood, using her shoulders for leverage. His cock attacked over and over, but still, her expression was unchanged. This seemed to devastate him. It must have been absolutely emasculating for him that using all his effort, his big muscles, and his massive cock to attack a girl's womanhood, it all amounted to nothing more than a mild annoyance.

Caleb whispered, "I'm gonna leave my mark all over your bottoms."

Caleb resumed his humping. He'd grope her perfect tits, and move her body back and forth so he could keep switching from her pussy to her ass. The intensity kept building in his face.

Layla whispered in his ear, "Now lets see what happens when my womanhood attacks your manhood."

Like a 1-inch punch, she slammed her pussy into his balls. Caleb was in too much pain to scream. His veins bulged so much I thought they would pop. Layla continued to read her book as she effortlessly ground her pussy into his balls.

She whispered, "Mmmm, now that feels good."

Layla kept getting more into it. She dropped her book, grabbed his thighs, and kept griding her pussy on his balls harder and harder. His body shivered, and he only breathed in tiny gasps. I'd never seen Layla so filled with bliss. Her pleasure boiled over into what appeared to be an orgasm, which she enjoyed while slamming her pussy over and over into his balls.

Layla took a few deep breaths. She picked up her book, then resumed her reading and light pussy-grinding on his balls. A faint smile formed on her face.

Part 3

Meanwhile, Ms. Aubert's ass was slamming into my balls because her sadistic daughter was driving into potholes. Her soft ass felt like an anvil to my balls. I couldn't take it anymore.

Barely able to form the words, I whispered, "Ms. Aubert, please, you're sitting on my testicles. They hurt."

Ms. Aubert covered her mouth and giggled. She seemed both amused and genuinely concerned as she whispered, "Oh, you poor baby."

The emasculation hurt almost as much as my balls. She slid her butt upward off my balls, causing my cock to go even deeper between her cheeks.

She whispered, "Let me make it up to you."

Ms. Aubert began expertly gyrating on my cock. One of her hands pulled out my balls and massaged them ever so gently. The fluid movements of her lap-dance were so pleasing that I knew she had to be a stripper at least at one point. I couldn't help but return the favor with my own thrusts, which brought a smile to her face.

She whispered, "You're cock is huge by the way." That got me going even more.

She moved her thong to the side, letting my cock go so very deep. It didn't take long for my pleasure to reach the edge. I breathed in ragged gasps. My hands grabbed her tits.

Ashley saw my euphoric face in the rearview mirror. Just as I was about to blow, she slammed on the breaks. All of Ms. Aubert's weight and inertia shifted to her hand that had been massaging my balls. I felt her hand flatten my balls against the leather seat to their very breaking point. The crushing agony was so sudden and intense that I pathetically whimpered, "My balls, my balls," over and over. It was like lightning bolts shot through my nuts to the rest of my body.

As I had my completely ruined orgasm, Ashley looked at me in the rearview mirror with the most devilish grin. I could do nothing but scowl at her in in my male-misery.

Ms. Aubert yelled, "That's it! I'm driving! Pull over!"

As Caleb continued getting his balls ground by Layla's pussy, he squeaked, "Can I please sit in the front?"

Part 4

We changed the seating arrangement. Ashley was coming to sit on my lap, while the handsome dad began moving to the back to be sat on by his daughter, Layla.

I knew I didn't have time to get rid of my erection. All I could do was hide it back into my thin cotton shorts. Not only could I lose my job and get in serious legal trouble, but I knew it was just straight up wrong to allow this.

Ashley had been sexually teasing me for years, bending over in my face, wiggling her tits at me. I'd always felt so guilty for jacking off to mental images of her, and I bet she wanted me to feel that guilt, wanted to be unable to resist her in a moment like this. Her plan worked. I couldn't stop this.

She opened the door and looked down at me with a grin that said 'you are mine'.

She stepped in, but before sitting down, she squatted with her perfect ass right by my face. Her pulled up track panties might as well have been a thong. The perfection of her ass and pussy peaking underneath turned me into a desperate boy who could only think, 'gimme, gimme, gimme. . ."

For a second, Ashley pressed her butt against my face. The pleasure of it sent my cock jumping and begging for it. She thrusted her cheeks down, then wiggled to get my cock nestled in between them. It felt so much better than I ever thought it would.

Layla sat on her dad's lap, who wore thin shorts similar to mine. His eyes slowly widened. I'm sure he must've felt even more conflicted than me. I couldn't judge him for taking pleasure in his daughter's ass, not when it's the best ass in the world.

Ms. Aubert got us on back on the road of bumps and craters. The Billie music still blasted.

Ashley leaned over and whispered to Layla, "I'm easily gonna make Mr. Johnson cum, but you could never make dad cum 'cause you're an ugly goth."

Layla whispered, "You don't seem to know how obsessed dad is with my ass."

Ashley whispered, "Then let's race. Whoever wins gets bragging rights forever."

Layla whispered, "Sure, I'm gonna win in less than a minute."

I was shocked by what I heard, and Mr. Aubert was even more so. He and I glanced at each other in a silent agreement that, 'if you don't say shit I won't say shit.'

Ashley and Layla grabbed each of our legs and got to work on our cocks. Their gyrations were forceful and absolutely heavenly. Each pump all around our length was it's own special gift. Ashley pushed the cooler onto the floor so she could get a better view of Layla's efforts.

Ashley could see precum already staining her dad's shorts. In a panic, she pulled my cock through my shorts. Her cheeks swallowed my cock and sensually humped it.

Layla pulled her dad's cock out and quickly devoured it with her cheeks. She seemed to clench her plump cheeks together, strangling his cock as she pumped it. Just like that, his body tensed. His breath came in short gasps. It was obvious he was about to cum.

Suddenly, Ashley reached out into the leg of her dad's shorts. The shape of her hand wrapped around his bulging testicles. She squeezed them so hard that her face strained.

Mr. Aubert's limbs shook as he silently screamed. He shook even more as Ashley cranked his balls left and right. She had successfully stopped his orgasm. He whimpered the same pathetic male mantra I had, "My balls, my balls. . ."

He mouthed "Stop," at Ashley.

She leaned over and whispered, "Sorry about your nutties, daddy."

Layla scowled at her sister. Ashley stuck her her tongue out at Layla and used her free hand to flip her off.

Ashley butt-fucked me harder and faster. The strength of her whole body added so much pressure to my rock hard cock. I could feel my intense pleasure boiling over. Ashley was about to win.

Just before I could finally have release, Layla reached into the leg of my shorts and squeezed my balls like a vice. The unbearable agony blocked my orgasm. My lungs shriveled as my body tightened and jittered.

"My- my balls." I mouthed the word, "Please," at Layla.

She sincerely whispered, "Sorry, Mr. Johnson." Layla began repeatedly tugging on my balls, making my limbs and head jerk each time. Each tug sent explosive shockwaves of pain through my nuts.

The twins' butts doubled their efforts on our cocks, trying to overcome our nut-pain. They whispered for us to hold onto their tits. I did immediately. Mr. Aubert hesitated. Layla jiggled her tits to further entice him. He gave in and grabbed them. It's shocking just how pathetically weak we males are against female sexuality no matter the situation.

Despite the ongoing torture of my balls, through the sheer feminine perfection of Ashley's body and movements, she brought me right back to the edge. Mr. Aubert seemed to be in the same spot.

Every time I thought I was about to finally cum, Layla was able to prevent it by squeezing, tugging, or twisting even harder. The same thing kept happening with Mr. Aubert.

The twins seemed to be enjoying the hell out of our hard cocks, and they seemed to love squeezing and manipulating our balls. Nothing was stopping their pleasure as it built and built. They both had simultaneous orgasms as they clenched even harder on our cocks, and squeezed our balls with even more strength.

The twins both pulled their track panties to the side. We were now straight up fucking in the backseat. It did not take long for the twins to each have another orgasm, causing them to clench even tighter on our cocks and balls. My big swollen testicles were deforming in their grip, and I'm sure Mr. Aubert's were as well. Our cocks were agonizingly just out of reach of release, as our balls were screaming for mercy.

Hard turns to avoid potholes often put even more strain on our balls. Our pleasure and pain kept intensifying, but my balls were too weak. I could feel they were about to give way and pop.

Just before they could, the car stopped and Ms. Aubert said, "Alright, getting here didn't take too long."

As she turned around to look back at us, the twins removed their hands from our balls. It was like opening floodgates. We had powerful orgasms, which caused our hips to involuntarily thrust hard at the twins' asses. Our cocks fucked them so hard they could not stop themselves from moaning.

Their mom saw and heard us. Her jaw dropped as her eyes jolted wide open. She yelled, "You fucking men! Girls can't even sit on your laps without you humping them and cumming!?"

As horrible as the situation was, the pleasure was still consuming us. Ms. Aubert punched her husbands balls, then mine.

We moaned in agony, but the heavenly pleasure was still at the forefront. As Ms. Aubert grabbed her hair in disbelief, we humped and humped with spurt after spurt. The girls had more orgasms.

Ashley moaned, "Oh fuck yes! Oh fuck yes!"

Layla moaned, "Fuck me, dad! Fuck me, dad!"

Caleb was filled with jealously, and his nuts were burning to cum. He grabbed his mom by her hips and hump her cheeks. Even as his mom began punching his balls, he seemed as if he was about to cum.

The tiniest moan of pleasure came out of Ms. Aubert. She leaned forward and pulled her panties to the side. Caleb pulled his cock out. They fucked without holding back, and within ten seconds, both of them came. All six of us moaned, three of us in both pain and pleasure.

Epilogue

Out of breath, we all agreed to never speak of this.

Just before starting the ride back, we admitted to ourselves what we truly wanted, and arranged our seats accordingly. I got to have the greatest ass in the world dancing on my cock the whole way.
