Keep in mind this is a first try, and yes, it's a long setup. I'm a writer who happens to be into ballbusting, not a ballbusting fan who likes to write. So... yeah. This is part one. Part two will be more action packed, if the crowd enjoys.

On all accounts, Mik was an average college freshman. A slender, fresh faced, bright eyed and bushy tailed rat of 18 who was trying to get used to life on the campus. His parents had generously paid for all the amenities. He had a pretty nice room, he'd picked a roommate (an old friend from high school), a meal plan that made sure he didn't go hungry or resort to Ramen, and a brand new computer to lug to classes.

There was, though, one little issue: Mik was a virgin, and his arrival on the college scene, surrounded by all the pretty girls, was sending his hormones into overdrive. Rat as he was, poor Mik had a set of testicles sized to the point of being a handicap. The heavy pair wasn't hard to notice even when he wore jeans, and they were doing their damndest to keep his brain focused on a little release.

But Mik was a good student, and mostly kept it to eyes only. He ogled the girls during class, staring at their bare legs and exposed cleavage during class (a perk of living in a warm area), and then took care of himself when he went back to his room and his roomie wasn't around. It wasn't the best solution, but he found that rubbing one out after class made it a hell of a lot easier to get his homework done.

One night, Mik was in the locker room of the school's gym, relaxing after a nice turn on the cardio equipment. He laid on a bench, one hand idly cradling and kneading at his hefty, pink nad bag, when suddenly he heard giggling girls! He practically fell off his bench, covering himself, when he realized they weren't in the locker room, just walking past. The locker room just had some serious echo to it.

Carefully, Mik stood up and went to the door frame, listening in.

"Oh my GAWD, Lynne, did you see Perry?"

"How could I miss him? I was waiting for his suit to bust!"

"I bet you'd be happy to cover him back up!"

"Oh shut up!!"

Then the noises died off, and Mik poked his head out just in time to see a tail disappearing into the wall. Biting his lower lip, the towel-clad rat lad tiptoed down the hall to see where the girls went. To his surprise, the girl's locker room was just a hop away from the guy's. Not only that, but those two weren't alone!

"Shit. Hey, can someone gimme a hand here?"

"Are you for real, Amber? Did you REALLY pop that strap again? You've gotta get those things taken down a size, girl."

"I do not! I just need a new suit."

Mik had found a gold mine: the girl's swim team! He stood there, staring, looking through a little crack in the semi-open door at the nude and semi nude girls milling around. A curvy white rabbit, who he guessed was Amber, had apparently broken a shoulder strap on her suit and was trying to repair it with... well Mik couldn't tell. Not that he was looking, anyway, the girl was facing the door and her tits were PERFECT. Heavy, but not sagging.

Before he knew it, Mik had a hard-on that could break a diamond block, and he didn't want to change getting spotted, so he skipped his way back into the locker room and ran into a stall to jerk off. It was the best orgasm he'd had since he arrived.

From then on, Mik had his schedule. It helped motivate him to go to the gym and left him all relaxed and ready to hit the books when he got back to his room. Over time, he started to almost get to know the girls, and now and again he thought about asking one out. After all, he had a pretty good grasp of their likes and dislikes, their personalities and whatnot.

As is so often the case, though, habit led to sloppiness. Those first few days his ears were on a swivel and if one of the girls so much as glanced toward the door, he darted back to his own locker room. But over time, he got confident, he felt like he "knew" the situation, and wouldn't you know it...

"Did you need something young man?" came a stern voice from over his shoulder.

Mik nearly jumped out of his skin. He spun around, dropping his towel along the way. There he stood, his chest heaving, with a stiffy that stuck out like a flagpole, in front of Ms Stitt, the girls' swim coach. An otter, unsurprisingly, she was a fit woman, and certainly not one to fuck with. At the moment, she was giving Mik a glare that would make the devil himself shrink down.

"I asked you a question!" she snapped, stepping closer. Nearly close enough to bump into the caught male's dick.

"I... it was... I didn't..." Mik stammered, at a loss for words.

Suddenly the otter grabbed him by the ear and started storming down the hall. Mik squeaked in pain, with no choice but to follow. He was terrified. A faculty member found him with his dick out watching the girls undress!

They walked down the hall a few paces, Mik doing his best to avoid the otter's thick tail as it whipped about. He certainly didn't want that thing smacking him up between the legs! She hauled him into what he assumed was her office and shoved him in a chair. Nude, erect, and incredibly embarrassed, Mik smushed his legs together and covered himself up with his hands. Ms Stitt, for her part, barely acknowledged his nudity, and instead just glared at him with crossed arms.

"Do you have ANY idea how much trouble you're in, young man?"

Suddenly Mik found his voice, and his desperation. "Oh my god, please, PLEASE don't report me! I'm sorry, it'll never happen again! I just didn't know you were there and I was changing and I heard noises and oh my god if my parents find out..."

She cut him off by holding up her hand and pinching two fingers together. "And they ARE going to find out. If you're lucky, you'll just get a fine and you might be allowed to finish the semester. If they call each time a separate charge, you might be looking at jail time."

That was all it took for the rat's dick to shrivel up and his ears to flatten down. "No! No, oh god. PLEASE! I can't go to jail! And if my parents find out, they'll KILL me! Please! I'll do anything, ANYTHING!" He clasped his hands up near his face, begging.

"Young man, after what..." The otter paused, as if just noticing Mik's naked body for the first time. She grinned ear to ear, her eyes rather fixated on that big, plump package laying in his lap. "You know what? Okay. You come to the auxiliary gym on Saturday morning, 9am sharp, and help me with a class I teach and maybe, MAYBE I'll consider letting this slide."

Mik could hardly believe his ears. Really? After all that? He looked at her in disbelief! "I'll be there! Thank you! THANK YOU!" He didn't get up though.

"...well? Get going!"

"I uh... a pair of pants would be nice."

************************************************** **

The next few days dragged horribly for Mik. He wondered what kind of class it would be that Ms Stitt wanted his help with. Swimming? Yoga? Oh that would be PERFECT. Maybe he'd get to see all the swimming girls again, and help stretch them out and give them foot rubs at the end, and then they'd go out and have wild sex every week. It had to be!

When Saturday finally rolled around, Mik sprang out of bed and practically sprinted down to the fitness center, going down the stairs and back to the auxiliary gym. Ms Stitt was there, a grin on her face that most would see as devious, but Mik hardly noticed. She tossed him a little bundle of spandex.

"Here, put that on."

"Um... what is it?"

"It's your outfit for the class. Those bulky clothes will just get in the way. Now hurry up, the girls'll be here any minute."

Mik didn't need a second bidding. He skipped into the small bathroom and stripped down, slipping himself into what he discovered was a wrestling singlet. It took some effort to get the thing on, and it was almost comically tight around his genitals. He looked at himself in the mirror, unable to avoid some flexing and posing, all the while making sure to thrust his hips out and show off that gifted package prominently.

"Man, when the girls see this, they'll be alllll over me."

He stepped back out, and was a little surprised to see that the swim team wasn't there, and there were only four of them aside from Ms Stitt. In fact, these women looked familiar for a different reason. Then it hit him, he'd seen them around campus, but as faculty! There was Mrs Cameron, the cheery squirrel who taught intro to art. Miss Ross, a bouncy young mouse girl who taught English courses. Sitting on the floor was Mrs Butler, a skinny but toned cheetah that he'd seen wandering around the political science areas. And then, sitting and stretching, was one he didn't recognize. She was a rottweiler, and looked like she could have played football, standing taller than him and definitely heavier.

Mik chewed on his lower lip, looking at all the women in the room. He was mentally ranking them, what order he'd fuck 'em. First the rottie, she looked like she'd take the most energy and go the longest. Plus, big as she was, she had all the right curves and that was what mattered. Then that mouse, just because he's always had a thing for fellow rodents, and she was especially cute. Mrs Cameron next, followed by that cheetah. Felines were never his favorite, and she was a little too thin. Fortunately, as far as staff went, this was a young-ish crew. No grandmas or middle-agers, although that rottweiler did look around his mother's age. And each was dressed similar to him, in a tight-fitting spandex workout outfit. It was hard not to stare.

"All right ladies, here he is!" Ms Stitt called out, surprising Mik as she was standing right beside him by the bathroom. She looped an arm around the rat boy's shoulders and guided him toward the rest. The ladies cooed and clapped.

"Ooo, he's cute!"

"And he's packin', just like you said!"

"Oh this is going to be FUN!"

Ms Stitt grinned and nodded, pushing Mik forward so he was standing in front of the girls. He felt faintly awkward, as though he were on display.

"Okay, girls. So we've spent the last few months working on that practice dummy, but I figured we needed some live flesh, and... Mik, was it? ... has volunteered to be our dummy for the rest of the semester!"

Amidst the cheering, Mik's ears perked up. He turned his head toward Ms Stitt, suddenly getting a very bad feeling. This didn't SOUND like yoga. "Wait... what? What is this?"

The otter nearly giggled and pinched Mik's cheek. "I told you, this is my women's self defense course! We've been working on one of those rubber dummies, but that just doesn't work too well after a while, you know? And we're all VERY grateful for your help."

Mik swallowed again. This was more than he'd bargained for, and a whole semester of it? He paused, thinking it over. Well, that meant rubbing up against them, right? And it's not like the TEACHERS of this school would be doing anything to hurt him. So he grinned and nodded, getting his confidence back. "No problem!"

The women grinned at one another, conspiratorially. Ms Stitt, patted Mik on the shoulder. "Okay then. We'll do the same drill from yesterday. Here, Mik, I just need you to grab my shoulders from behind."

The otter turned her back to him, and Mik found himself staring RIGHT at her ass. It was perfect. Round, toned, with that sexy lift that shifted side to side with every step she took. He could just imagine what it'd be like to bend her over his desk back in his room, lift that big tail out of the way...

"MIK!!!" Ms Stitt barked.

"Oh! Oh, right. Um... sorry. Heh. Right, here we go." He wasn't quite sure what to do, so he stepped up somewhat awkwardly and put his hands on the otter's shoulders.

*WHAM!!*

Before he even knew what happened, Ms Stitt had mule-kicked back into him, her bare heel catching Mik square in the 'nads. The force of her kick rattled his hips and picked him up onto his toes. Worse still, his left nut had squirted out right after the impact, leaving the left to take the remainder of the blow all by its lonesome.

In too much pain to even yell, Mik let out a terrible, shuddering moan as he slipped to the mat and curled up. He'd taken LITTLE hits to the nuts before, but never a direct kick! He laid there, wailing and writhing, looking up at the otter that had just racked him. The other women looked concerned, amused, and excited. All at the same time.

"What the fuck?!?!" he shrieked, briefly wondering if his nuts were going to have a permanent footprint on them.

Ms Stitt rolled her eyes and just turned to the class. "Remember, if the opportunity is available, ALWAYS go for the balls. One kick, one knee, one good hard squeeze can be enough to incapacitate the attacker. Miss Butler, how about you go now?"

"YOU CAN'T DO THIS!!" Mik yelled in protest and terror. His anger shifted to alarm when the otter suddenly grabbed him under the armpits and started hoisting him up.

"Oh be quiet, you volunteered," she said casually, 'helping' him stand again. Along the way, she whispered in his ear, "Remember, if you don't, it's right to the police and the dean."

Oh fuck, Mik thought. She was blackmailing him, and there was nothing he could do about it. If he caused a fuss, he'd have to admit that he was peeping on the girls and jerking off. If he stayed quiet, who knows how much more of... THAT there was to come. But, bad as it was to get his eggs punted around, it was better than expulsion and arrest. Besides, it wasn't going to be just a whole semester of getting his nuts kicked around, they HAD to pick other lessons.

When he was up, the mouse stood in front of him and looked hesitant. She shook her head. "I can't! It looked like it hurt!"

Ms Stitt laughed, "Well of course it hurts! That's how you know you're doing it right. But don't worry, Mik volunteered, so there's no problem about going too rough." She nodded, giving Mik a pat on the belly that only knotted up his insides worse. He groaned pathetically.

Still, the mouse was unsure, so Ms Stitt rolled her eyes. "All right, look. We'll just get you used to the idea, okay? Mik, spread your legs."

The rat was horrified. It was one thing to grab a girl from behind and get taken off guard, but now she wanted him facing her? And to just open his legs up and ASK to have his eggs scrambled? He started to shake his head when the otter's glare stopped him.

"I said... spread your LEGS."

Whining pathetically, Mik did as he was told. It took some work, but he got them apart, the spandex garment keeping his swollen and oversized ratmakers held together. Miss Butler stared at his set, her tail lashing around behind her.

"Now then," the otter continued. "Make sure to line it up. Then just let it fly, and try to kick THROUGH him. Imagine you're going to make it up to his head."

The mouse was still reluctant, but she lifted her leg up and pressed the top of her foot against the underside of Mik's scrotum. She wiggled her toes and shifted the parts around, getting a feel. He murmured and moaned, which seemed to lighten HER mood, if not his. That was when...

"Oh my GOD! He's getting HARD!"

It was inevitable. A bunch of pretty women in tight clothes, ogling and touching his manly parts? Of course he'd get a hard on! The four women were horrified, but Ms Stitt was casual. "It's natural, ladies, perfectly natural. BUT," she said, grinning at Miss Butler. "I do think it's rude. Don't you?"

The mouse nodded, her brow furrowed. She took one step back and then swung her leg up between Mik's thighs like she was trying for a field goal. The slap her foot made off of his nuts was loud enough that the otter actually winced, and Mik's already aching ballpouch got flattened again.

"CRUNCH!!" the cheetah whooped, punching at the air.

Mik squealed in agony, collapsing to the floor and writhing. He thought the first kick was bad, but getting another one so soon after was just too much to bear. He was SURE his nuts were broken, he was SURE they'd never work right again.

"F... fucking bitch!!!" he managed to croak out.

*THUMP!*

The otter nailed him from behind again, sending Mik sprawling and clapping his hands over his thrice-busted balls. "Now that's not how we speak to a lady, is it?"

Laughing, she addressed the class. "See? It's easy. Just line up and let 'er rip. Who wants to be next?"

"Me!"

"No me!"

"But you just went!"

"I know, but I wanna go again."

Mik listened as the women enthusiastically asked to be the next to kick his balls, and he had a feeling he was going to be in for a long, long semester...
