Senior Slump Part 9: Before Break

Part 8: https://www.reddit.com/r/BallbustingStories/comments/18y4p1d/senior_slump_part_8_attendance/


Glad to finally have this part finished! I've been sitting on it for ages and after a while, it just felt like a chore to try to get it done. It's a long one. Hopefully y'all enjoy it even thought it was such a slog to get through. I might be leaning away from the whole class thing, tbh, and moving things in a different direction as it feels like its getting a bit stale and boring to write. Anyway, hope you like it!

----------------------------------------------------------------------------------

It was the day before winter break, and Ms. Powell had asked Sam to come early. He arrived at the classroom about twenty minutes before the bell to find Ms. Powell waiting, absentmindedly scrolling through her phone. She looked up as he entered.

"Ah, Sam, perfect. Thank you for being willing to come in early. I wanted to get a head start today."

"Uh, sure, no problem." Sam said, dropping her bag off at his seat and returning to the front.

"So...?" He asked.

Ms. Powell was stilling scrolling through her phone, a slight grin on her face.

"Yes, sorry, I was just getting at some inspiration." She showed him her screen. It was a Twitter feed, with picture after picture of swollen and bruised balls. He gulped.

"You see, since we're not going to be meeting for a few weeks, I thought it would be best to get in as much damage to those fat balls of yours as we can, so that it will hopefully last you until school starts again. I know you'll still have your family to bust you at home, but I just don't think they'll be able to do enough. Now, I know this might sound like a lot to ask of you, but I promise it's gonna be worth your while. That's partly why I asked you to come in early today. But you get before your gift, I wanna make sure your balls are good and tender for class. So if you don't mind dropping your pants."

Sam gulped again, but was intrigued by the promise of a reward, so he did as instructed and stripped.

"Perfect. Now come over here, I don't want to have to stand."

She firmly gripped his sack and led him around to her chair, where she sat. She looked at the time and set a 15 minute timer, then smiled up at him, saying, "Here we go."

She started relatively softly, each hand squeezing one ball, pulsing little waves of pain through his body. Then she squished them together between her hands and rubbed them roughly back and fourth, as if she were kneading two lumps of clay into balls. Once she seemed to feel they were sufficiently kneaded, she gripped them tightly with both hands, and pulled them down, stretching his sack as far as it would go. Once his sack was loose enough, and she had a good few inches of slack, she pulled him closer to the desk and slapped his balls up and down against the hard wood a few times, eliciting small moans of pain from sam on each impact before resting them down and rubbing them hard against the surface. Sam was already starting to breath more heavily. His balls both stung and ached from being smacked against the desk. She checked the timer smiled up at him again.

"Good ten minutes left to really get these things swollen." She said, in a slightly horse voice. Sam noticed her cheeks had begun to flush. Clearly she was enjoying herself.

With his already swelling balls resting on her desk, she started in on them in earnest. First with hard, painful, flat handed slaps, then for the remaining ten minutes, she pounded his balls against her desk with her fist, the brutally painful blows growing harder and harder, alternating focus on each testicle, as the minutes ticked by at what felt like to Sam as an excruciatingly slow pace. He hunched over, teeth clenched, sweat drenching his body as his teacher pounded away at his aching balls. The shear pain stopping any screams in his chest, yet at the same time causing his cock to ache with excitement and pleasure. Bang, bang, bang, bang, bang. He was sure his balls would explode with each consecutive hammer blow of Ms. Powell's fist, until finally, her phone vibrated, signaling the end of the ten minute torture session. She finished it off with one, good, hard, full force smash to his nuts, which were now bright red and swelling nicely.

Ms. Powell took a breath and blew an errant strand of hair out of her face.

"Excellent." She said, "That was a great start. I think we're going to be able to really fuck up your balls today, Sam."

She giggled as he collapsed onto the floor, cradling his balls.

"Don't worry, I didn't forget about your reward." She checked the clock again, "And I think five minutes will be more than enough, given the state of your cock."

Sam glanced down, and indeed, his cock was rock hard and dripping precum. He could explode at any second.

"Do you remember the promise I made to you when you agreed to be the class's painslut, Sam?"

"Uh, I think so." he said, excitement beginning to bubble up inside him about what she was implying.

"Well, don't say I never gave you anything." she winked at him and she sat back on the desk and hiked up her skirt, revealing her soaking wet cunt. It was neatly trimmed, but hairy, her large labia glistening with lust, and her enormous clit seeming to throb with excitement. To Sam's surprise, the outer lips of her pussy were pierced with thick metal rings, attached to which were chains that held her pussy wide open. His cock twitched with excitement at how depraved his teacher was.

"I thought you'd like this." Said Ms. Powell, her chest heaving, "Today is your lucky day, Sam. You get to fuck your teacher."

"R-Really?" Sam stammered.

"Really. But you'd better hurry up. Only four minutes left." She said, holding up her phone.

"Yes, ma'am." Said Sam, scrambling to his feet and cautiously approaching her.

She leaned forward, bringing him into her embrace.

"Now stick that fat cock in my slutty little pussy." she whispered in his ear.

She reached down and grasped his cock, sending ripples of excitement through him, and guided his tip to her welcoming cunt. With a gasp, he entered her, and his mind went blank. The ecstasy of the sensation overwhelmed him. The heat, the pressure, her soaked cunt engulfed him in pleasure and pulled him in deeper and deeper until his entire length was thrust insider his teacher. She softly moaned and stroked his hair as he began to move, fucking her gently and slowly, trying to prolong the experience, trying to hold back the tide of euphoria that had been building for the past 20 minutes. But Mr. Powell knew his weakness all too well, and as he thrust home once again, she reached around, took his swollen balls in a vice grip and yanked on them, hard. This pushed Sam well past the edge, and his orgasm erupted deep inside his teacher's cunt, filling her to the brim with hot cum.

"Fuuuuuuck" he gasped, his vision briefly leaving him as he came. Before he could finish his orgasm, though, Ms. Powell pushed him off of her and into her chair, then dropped to her knees and started jerking his cock as hard and fast as she could.

"Don't enjoy it too much, slut." She said mischievously.

Sam's entire body immediately tensed, every muscle screaming out for the sudden, overwhelming sensation to stop. He dug his fingernails into the arms of the chair as Ms. Powell worked his cock over, giving excruciating attention to the head, squeezing it, rubbing the glands with her thumb, and stroking it with unbearable speed. Sam could hardly breathe, the sensation was so intense. Then, just when he thought it would never end, the bell rang, and Ms. Powell mercifully released him.

"Better get to your place, slut." She said cheerily, wiping her hands on a tissue from the box on her desk. "You're balls still have quite a day ahead of them."

Sam grunted weakly, panting hard.

"Here, let me help you, dear."

She helped him to his feet and over to the desk near the door, and soon the class started filing in, each girl giving Sam's already bruised balls a hefty smack or punch as they passed him. Samantha delivered her, now daily, brass-knuckled punch to his aching gonads. At this point, Sam's legs were already shaking, and his balls felt simultaneously flattened to all hell and more swollen than they'd ever been. As Penny passed him, she opted to lean heavily on his nuts, briefly going up onto her tiptoes to push all her weight into his balls. She smirked at the gasp of pain he let out, then went off to her seat. Once everyone had arrived, Mr. Powell addressed the class.



"Good morning, ladies. Hope you're all doing well. Now, I know we're all excited to get out of school and go off to break, but I want us all to focus up today. We're gonna be gone for two full weeks, and that we won't be able to put in the work on Sam's balls. I don't know about you girls, but I don't feel like we should let him off that easily, do you?"

The girls laughed, and several let out enthusiastic "no's!"

"Exactly. So to make sure he remembers his place over the break, today we're going to have to really teach his balls a lesson. We're gonna have to flatten those nuts completely, beat them and smash them until they're goo. I've also brought some new toys so we can start stretching out that little cock of his."

She pulled from behind her desk a black briefcase, which she opened, revealing a set of intimidating looking steel rods of increasing thickness, as well as several thin, ridged, dildos, the largest of which Sam guessed was probably at least an inch thick.

"We'll start small, but I want us to be shoving this dildo here all the way into that cock by the end of class, okay? Now, let's get started, shall we?"

She brought Sam to the center of the class, and gagged him.

"Now, to kick things off, why don't we start with some good old fashioned kicks to the balls? Why don't you ladies form a line and take turns. And can I get a volunteer to start in on the sounding?" she held up the set of steel rods.

Penny raised her hand with a somewhat flushed grin.

"Perfect. Then, if you would come up here, I've got the sterile lube here."

While the rest of the class formed a line in front of Sam, his sister came to the front and Ms. Powell started to instruct her on what to do.

"So, it's simple enough, you just lube up the rod, squirt some lube into his urethra, and then start fucking. You'll want to start slow, since your brother's cock is still a virgin. But don't go too easy!"

"I won't." Penny smiled. She took the smallest rod from the set and grabbed the tube of medical grade lubricating jelly, and knelt behind Sam, who was now on his knees, assuming the position. She caressed his bare right ass cheek, snaking her hand around his waste before wrapping her hand around his sensitive cock. She whispered in his ear,

"Does this turn you on, big brother? Your little sister's tiny little hand gripping your big, fat, cock?"

Her whispers sent shivers down his spine, and blood rushing into his penis once more. He felt Penny smile against his ear as she slowly stroked him.

"Fuck, I'm so wet, bro. This is so weird, but it's so hot."

She generously lubed up the rod and slowly slid it into Sam's throbbing tip. He hissed as the cold metal sapped the warmth from inside his cock. Focusing on this new sensation, he wasn't paying attention to Ms. Powell when she said,

"Alright, girls, show those balls who's boss!"

As Penny began to increase her pace, causing his dickhole to burn, he looked up just in time to see a black combat boot slam furiously into his swollen balls. He screamed into his gag and tried to double over, but Ms. Powell and Penny held up upright as Samantha slammed her heavy boot into his balls three more times. Tears formed in his eyes as the brutal pain washed over him. He could barely think as he felt Penny jerk his dick faster, perhaps out of sympathy, he thought. The intensity of everything had him on edge again already.

Making progress with the sounding rods, Penny moved up to the next size, pushing it all the way down until it almost disappeared into his cock. He arched his back and gritted his teeth. The feeling was exhilarating, both painful and pleasurable. He felt the soothing hand of his sister stroke his back, the other still holding his cock, her face pressing against his shoulder. It was strangely intimate, surrounded by his classmates, but for a moment, feeling as if it was only he and Penny there.

Next in line was Lacy, who looked down at hims with both arousal and concern on her face. Instead of kicking him, she knelt in front of him and gently squeezed his balls.

"Hang in there, Sam." she whispered, "I feel weird about doing this stuff now that.. you know.. So, here."

She lowered herself further, and to Sam's, and everyone else's surprise, she took his cock into her mouth, rod and all, and briefly sucked him, her tongue playing with the tip of the sounding rod protruding from his dick.

"Let's keep things moving, ladies. We don't want him to have too much fun, right?" Ms. Powell gently chided.

Lacey rose, embarrassed and said,

"Right. Sorry. Um. I'll just.." and she hurried to the back of the line, her face burning.

From then on, the line moved mote quickly. Each girl delivering a ball shattering kick to Sam's junk, and then moving on, all while Penny fucked his cock with increasing sizes of rod, until they were at the largest size his cock could take. It was about the width of his ring finger and it stretched his dickhole as far as it would go.

Finally came the mousy haired Sasha, and for the first time since he'd seen her, she looked pissed. Gone was her normal timidity, now replaced with a look of pure frustration. She marched up to Sam, rested her hands on his shoulders, and began to kick, hard. Her soft toed shoes did little to lesson the impact of her relentless kicks as she bashed her foot into his groin over and over and over again. Soon, the dual stimulation and intense humiliation had cum dribbling past the rod in his cock, but Sasha was in no mood to stop. Sam could barely whimper as the brutal attacks kept coming, flooding his system with pain. His hyper sensitive balls were screaming out for it to stop, but there was nothing he could do but take it. Minutes passed as she did her best to ruin his balls. Until finally, as Sasha finished her barrage of kicks, Sam could hear her mutter through gritted teeth,

"Why, are, boys, so, fricking, stupid!" Each word punctuated with another, angry kick.

Once she was done, Sam's head dropped to his chest and he felt like he was about to pass out.

"Hey, Ms. Powell, I really think he needs a break. That was a lot." Penny said, slight fear coloring her voice. In some far off place in his mind, Sam felt touched by her concern.

"Um, yes, good idea." replied Ms. Powell, sounding as if even she had not expected the level of violence Sasha had dished out. "Actually, it's getting late, and since it's the holidays, why don't I let you all go early today?"

As the girls started to grab their things and began to filter out, Penny assisted Ms. Powell in undoing Sam's restraints and cleaning him up. Still somewhat delirious, they helped him into Ms. Powell's chair. Soon enough, it was just the three of them left, and his balls were nestled into a soothing ice pack which Penny had retrieved from the nurse.

"Are you sure he's going to be okay?" Penny asked again.

"He'll be fine, dear, I promise." Ms. Powell said kindly, "And I just wanted to apologize again, Sam. I know you agreed to all this, but I really didn't think- I mean, I've never seen Sasha like that before. I would have taken it a bit easier on you before class if I had thought- Well, in any case, I'm sorry. I probably should have stopped her sooner. I hope this doesn't make you think twice about participating in this class. I promise I'll be more careful after break, okay?"

Sam merely nodded. It was all he could muster. He didn't have the energy to think about what she was saying, all he could focus on at the moment was his aching balls.

"Alright, then." Ms. Powell said, giving his knee an encouraging squeeze, "I'll let you two go then. Have a wonderful break, and I'll see you next year."

Penny slowly helped Sam to his feet and put his arm around her shoulder as they exited to classroom.

"I texted mom. She'll be here in a few minutes. Figured you'd rather not try to walk home or ride the bus today." Penny said with a sympathetic smile once they were alone in the hallway.

"Thanks." Sam managed to grunt.

"Seriously, though, Sam, are you okay? I mean, I'll admit, I've been having fun with the class so far, but today was... Shit, Sam, that was fucked up what Sasha did. I thought you were gonna pass out, you looked so-" she broke off, biting her lip, and to Sam's surprise, he could see tears beginning to form in her eyes. The sight was worse than all the pain he'd endured that day - an observation that again, surprised him. Whatever this was between him and Penny, it wasn't just casual fun anymore, not just siblings exploring some weird feelings - something had changed today.

Sam pulled Penny into a hug and kissed the side of her head.

"Hey," he croaked, "I'm okay, alright? I'm gonna be fine, you heard Ms. Powell. I just need some rest and, well, a lot of ice, heh."

"Shut up, don't make me laugh." Said Penny into his shoulder.

She pulled away from him and gave him a serious look.

"Seriously, Sam. I don't know what all you agreed to with Ms. Powell, but I don't know if you should keep doing this. It's been okay up to now, but after today. And fuckin' Samantha with her brass knuckles? How is that okay? I was kind of caught up in the whole thing, but I don't know anymore. Sasha went too far. I mean, its fun to bust your balls once in while, but I don't want you to actually get, like, seriously hurt, okay?"

"Yeah, I- I don't know." Said Sam, unsure of how to feel.

Half of him agreed with Penny, and he felt a rush of affection for her at how protective of him she was being. But another part of him knew how intensely hot it had all been. He could still feel Lacy's lips around his cock, slowly sucking the sounding rod out of his dick. And there was also the fact that if he hadn't agreed to all this, this new thing with Penny would never have happened. Lacy would never have confessed. He would never have gotten to fuck Ms. Powell. His mom would never- he stopped that thought in its tracks, still very uncomfortable with where that all might be heading.

Soon enough, having moved outside to wait, they saw their mom's car pull up along the curb, and their mom, concern all over her face, rushed out to help Sam into the car, doting on him like a mother bird, and then they were off, back home for the holidays.
