Senior Slump Part 3: "I'll Do It"

Part 2 (https://www.reddit.com/r/BallbustingStories/comments/18y49ml/senior_slump_part_2_getting_hands_on/)

As the girls began to line up in front of him, Lacy in the middle, his sister at the back, Sam's excitement grew even more intense. His dick twitched with anticipation, and precum leaked from the tip. The first girl in line was a slightly chubby girl, with large breasts, short, spiky blue hair, and two snake bite lip piercings in her lower lip. Heavy black combat boots adorned her feet. Sam gulped. She smirked down at him as she approached, and then looked up at Ms. Powell for direction.

"Go on, Samantha, hard as you can." said the teacher.

Wham! With the full force of her powerful legs, the girl planted a nut cracking punt into Sam's groin. He screamed into his gag and doubled over, a few tears leaking from his eyes. Several of the girls burst out laughing, while others winced in sympathy.

"Wonderful! Great job, Samantha!" explained Ms. Powell.

Samantha beamed with smug pride and walked to her seat.

The next girl approached, and, like Samantha, looked to Ms. Powell for permission.

"Yes, for for it! And from now on, girls, when it's your turn, feel free to just get right into it, okay? No need to hesitate. We don't want to make this take any longer than it has to for Sam's poor balls."

Sam didn't even have time to register who the girl in front of him was before he felt another hard shoe smash into his tender nuts.

"Fhufck!" he wheezed, spittle dripping from his open mouth.

And then another, THUD! And another, SMACK! And a third, WHAM! These kicks left him panting, his head hanging down, and yet, his cock, still twitching violently from the abuse. He hated to admit it, but he fucking loved this.

The next ten kicks came in quick succession, varying from somewhat weak compared to Samantha's initial kick, to mind numbingly intense. All the while, the crowd laughed and groaned and cheered, encouraged by Ms. Powell's occasional compliments on form or intensity.

Finally, it was Lacy's turn at bat. She leaned down before her kick and lifted his face to hers.

"Hanging in there, donkey balls?" she said with a sympathetic smile.

Bleary eyed, Sam looked up at her, and in his haze of pain and pleasure, was suddenly struck with the thought that she was, in fact, one of the most beautiful women he had ever seen. He gulped, and still breathing hard, nodded.

"That's good. Come find me after class, okay? I have something I want to say."

Sam nodded again, and she smiled warmly at him before straightening up. Then she reared back her foot and slammed it, hard, into Sam's balls.

And then it was back to the kick after agonizingly hard kick to the swollen testicles. Nine more kicks came, one right after the other, with one of the girls - the small mousy haired one who sat on Sam's left - even taking a running start, to land a particularly hard punt into his groin. Then, finally, it was Penny's turn. His own baby sister. Standing in front of him, saliva dripping down his front, his thick cock, stained with cum and leaking continually, hard as a rock, and his big, fat, swollen balls, hanging down between his legs - the perfect target for her to kick. And it excited him more than anything else had that day. He soaked in the shame and humiliation as he looked up at his younger sister. Her face showed that same odd expression from before, which he realized now, almost perfectly mirrored his own feelings. Excitement, trepidation, shame, arousal - it was all there on her face as she gazed down at his twitching penis.

Then their eyes met, and knowing she needed the push, he gave her a small nod. She let out a soft gasp, stared intensely into his eyes, and then nodded in return. Without a second's more hesitation, she placed her hands on his shoulders, lifted her leg, and kicked him as hard as her athletic legs possibly could. He let out an agonized cry, doubling over, his head coming to rest in on Penelope's stomach, and for the second time that day, came harder than he had in ages. Cum splattered all over Penny's shoe, and dripped all down his pulsing cock and he shook with the aftershocks of the powerful orgasm.

Penny, too was breathing hard, her long blonde hair draped over Sam's prone form, obscuring both their faces. She kept her foot in place for several more seconds, slowly massaging his balls with her show, while the class cheered at the finale of the show. Then she suddenly straightened up, and promptly went back to her seat, with an embarrassed smile on her face. She would meet Sam's eye for the rest of the class.

"Well done, ladies! Really good job today." said Ms. Powell, helping Sam into her desk chair and removing his gag, "I think I'll let you go a bit early today. I have some things I need to discuss with our brave volunteer here, and a few messes to clean up, so, you're all free to go. No homework today. See you all next time."

Then the class slowly filed out, many thanking Ms. Powell for the experience and she went about cleaning Sam's cum off the floor, and a few including Sam in their thanks as well. One such girl was Samantha.

"You're pretty fricking tough, Sam. I'm impressed. I've never known a boy who could take a kick like that from me without dropping. Honestly kinda hot. Anyway, see you later."

"H-heh, thanks." he replied weakly, "You're not so bad yourself."

Sam noticed a distinct rosy glow on her cheeks as she left the classroom.

Once the last of the girls had made their way out of the classroom, Ms. Powell turned to Sam.

"I want to thank you for being such an incredibly good sport, today, Sam. I know I put you through a lot." She gave him a sympathetic smile, and walk over and knelt in front of him, placing a hand on his leg. It was only then that Sam realized that his shorts were still down around his ankles.

"It's not many young man who can take such a beating to their balls in stride like you did, and I want you to know I'm very proud of you for taking it."

Not knowing what to say, Sam simply said, "Uh, thanks."

"To be completely honest, I had a hunch you would enjoy it. I've heard stories in the teachers lounge, you see." she began to slowly caress his thighs now, "About some of the things that happened to you in middle school. It's nothing to be ashamed of. These memories, these little traumas, they have a habit of developing into other things as we get older." she moved her hands gradually closer to her cock with every stroke of his thighs, "As we discover our sexuality." she whispered the last word into his ear, running her hands up his body, and now her breath tickled his ear as she breathed. "It's the mind's way of dealing with it, you see? It takes a painful memory from our past, and turns it into something... Pleasurable." And then her hand was on his cock and he gasped in pleasure as she stroked him, his mind a haze of pleasure.

"I have my fair share of kinks, too Sam." she said breathlessly, undoing her sweater, "I know exactly how you feel." she let go of his cock for just a moment, just long enough to pull down her shirt and bra and free voluptuous breasts, each the size of a cantaloupe, with large, red areolas, and pierced, protruding nipples, with thick silver rings through them. "I know how good the pain can feel." she said, now stroking his cock faster.

"Fuck, Ms. Powell." Sam breathed.

"Pinch them, Sam, pinch my fucking nipples as hard as you can. Twist them, make them hurt for me." she begged in his ear

He obeyed, pulling on the rings, twisting, and abusing her breasts to the best of his ability.

"Yesss, fuuuck." she moaned, reaching one hand down into her skirt. "That hurts so fucking good, baby." she whimpered, jerking his cock furiously.

This sent him over the edge,

"Fuck, I'm cumming." he groaned.

Then Ms. Powell surprised him by leaning down and taking his cock into her mouth. He grunted, and bucked his hips as he released his load into his teachers mouth. She swallowed it down eagerly, and when he was done, they both sat there for several minutes, panting. Eventually, Ms. Powell got up, and fixed her clothing, turning her back to him for a moment, before facing him again, her usual air of confidence and poise returning.

"Now then. Before I let you go, you have a decision to make. I realize that you didn't have a lot of choice in today's events, Sam. And while, believe me, I know that was part of the fun for you, that's just not how I do things. So you have two options. You can either, one, back out of this whole thing, take the class just like any of the other girls would, and get that easy A I assume you were after. Or," she paused then, and knelt in front of Sam again, hefting his shiny red balls in her hand, "Or, two," she spoke with gravity and purpose, "You can agree to become this class's pain slave, and forfeit all your rights as a man within these walls. If you do this, you will have no safeword, no way to tap out. Your balls will belong to this class, and we will use them and abuse them until they are black and blue and you are curled up in a ball, sobbing for your mommy. We will push you to the limits of pain and far beyond. We will make you beg us to castrate you, to just squash these donkey balls once and for all. And if you do this, Sam, we might just obliged you, and turn. These. Balls. To. Mush." She punctuated those last words with five hard punches to his balls.

Same shuddered from the pain and pleasure. His mind was racing, his heart was racing. He was so turned on, but so afraid at the same time.

"But if you do this, I can promise you, it will be like nothing you've ever experienced before. You will get to experience the most intense pleasure this life has to offer. I will guide you past the limits of sexual ecstasy, and help you fuck every single one of the girls in this class. It will be an orgasmic orgy of pain and pleasure the likes of which you cannot even imagine. And by the end of it," she once again whispered in his ear, "By the end of it, you'll even be fucking your own sister."

"I'll do it." he heard himself say.

"Good boy."

WHACK!
