Amy smirked as she quietly pushed open the door to Bruce’s room. The scent of sweat and dirty gym clothes filled her nostrils, making her scrunch up her face.

The memory had come back to her so vividly two weeks ago—her tooth was wiggling with the slightest touch, it caused her some discomfort and she constantly complained about it.

So her twin brother, Bruce. A meathead who only knows how to workout, eat, sleep, game, and be a pervert. Said he had an idea to remove her tooth.

All he needed was a door, string, and the wiggly tooth his twin whined about.

“Nonono!! I’ll just let it fall out on its own! I’m sure it’ll be soon.” Amy says wiggling in fear.

“Ok! Ok stop being a baby!! I’ll count to ten so you can prepare yourself!” Bruce says as he finishes tying the string on her tooth.

He finally finishes tying the other end of the string to the door and gives her a heads up.

“You ready? Ok good! Remember.. I’ll pull on ten, got it?” He says not even letting his sister give her answer.

One.

Two.

Three.

FOUR!!

He slammed the door shut, the intense force from the string yanking her tooth, causing the loose tooth to instantly fly out of her mouth. She’d yelp, small drops of blood in her mouth, while her twin brother laughed like it was the funniest thing in the world.

Now, weeks later, it was time for payback.

Bruce was passed out in his gaming chair after a long session of doing nothing but jerking off, and gaming. His headset still half-on, controller in his lap. And his thick erection pulsing with each breath he took.

Perfect.

Amy moved fast and silently. Her fuzzy socks blocking all the sound against the wooden floor. She taped his wrists and forearms tightly to the armrests with thick duct tape, then carefully slid his pants down just enough to expose him.

His large, heavy testicles hung vulnerably between his spread thighs. She looped a strong, thin nylon string around the base of his sack, cinching it snugly but not yet painfully tight. The other end she tied securely to the handle of his bedroom door, leaving just enough slack that the door could open inward a few inches before the line went taut.

She stepped back, admiring her work, then stripped down to a tight white tank top that clung to her breasts and a pair of light pink panties decorated with tiny silver heart charms. Her nipples were already hard with excitement.

“Wha—? Amy? What the fuck?!” Bruce stirred, groaning. His eyes fluttered open, then widened in confusion as he tried to move his arms.

“Morning, sleepyhead,” Amy said sweetly, standing right in front of him with her hands on her hips.

The string lay across the floor between his legs and the door.

“Jesus Christ, Amy! What is this?! Let me go right now!” Bruce looked down, saw the string tied tightly around his balls, and jerked hard against the tape.

“Remember when I had that loose tooth? You told me you’d count to ten, then yank it out gently with the string tied to the door. Instead you slammed it before you even hit five. I cried for an hour, Bruce. Blood everywhere. Mom was pissed.” Amy giggled, twirling the end of her long hair.

Bruce’s face paled as the memory hit him.

“That was like… weeks ago! It was a joke!! Come on, sis, this isn’t funny. Untie me.” He says struggling against his restraints, clearly fearing for the chance of his future children.

“Oh, it’s funny to me,” she said, stepping closer.

She hooked a finger under the string and gave it a light tug. Bruce hissed as his balls lifted slightly.

“O-ok… W-W-wait! Let’s talk about this!!” Bruce says his voice now trembling.

“I’ve been waiting for the perfect moment. And here we are. Your big, fat balls all tied up and ready for some revenge.”

Bruce swallowed hard, eyes darting between her barely-covered body and the opened door.

“Amy… please. This is messed up. We’re siblings. You can’t—”

“I can,” she interrupted, voice dropping to a teasing whisper. “And I will. But first, I want to hear you beg. Beg your little sister for forgiveness. Tell me how sorry you are for being such a cruel prick.”

Bruce strained against the tape again, breathing faster.

“Okay, okay! I’m sorry! It was a dumb prank. I shouldn’t have slammed the door. I felt bad after, I swear. Just… please don’t do this.”

Amy tilted her head, smiling.

“That’s cute. But not nearly good enough. Try harder. Get on your knees with your words, Bruce. Tell me how much your balls belong to me right now.”

His voice cracked with rising panic.

“Amy, please! I’m really sorry! I’ll never prank you again. I’ll do whatever you want—chores, money, anything! Just don’t slam that door. My balls… they’re sensitive, you know that. Please, sis. I’m begging you. Forgive me.” He says as his pathetic begging brings a smirk to his twin sister’s face.

Amy stepped back toward the door, gripping the handle. She pulled it open a few inches, taking up the slack until the string was perfectly taut. Bruce’s testicles were now pulled slightly forward, the skin stretched tight.

“Beg some more,” she cooed. “Tell me you deserve this.”

“Fuck— I deserve it, okay?! I was an asshole! Please don’t pull any harder. I’m so sorry for yanking your tooth out like that. I was stupid. I love you, you’re my twin. Please, Amy… mercy.”

Amy’s eyes sparkled with wicked delight.

“Nah.”

She slammed the door shut hard.

*THUD* *CRUNCH\*

As the door slammed shut, the string snapped tight instantly. Bruce’s entire body jolted violently in the chair as a raw, crushing agony exploded through his groin.

“AAAAAAHHH! FUCK! MY BALLS!” Bruce cried out as his balls were being pulled to excruciating lengths.

His heavy testicles were brutally yanked forward, smashing against the resistance of the door. He screamed, eyes bulging, legs kicking uselessly.

Amy opened the door again, letting the string go slack for just a second, then slammed it even harder.

*CRUNCHH\*

“GAAAAAHHH! STOP! PLEASE! IT FEELS LIKE THEY’RE GONNA RIP OFF!” Bruce groans loudly, his voice raising a few octaves higher.

She laughed, clearly enjoying the way his muscular body thrashed and the desperate, high-pitched sounds he made.

“Aww, does it hurt, big brother? Good. This is for every time you were mean to me.” She cooed, cupping her hands over her smooth crotch, mocking him about his boy pain.

She slammed it a third time, harder.

*BOOM* * CRUNCHHHHHHH\*

Bruce’s scream cracked into a sob. His balls were swollen and bright red, the string digging deep into the base of his sack.

“MYYyyYYYyyY NNNnnUuUtTTTtsSs~!!!” Bruce cried for all to hear. His voice was high pitched and pathetic, the mark of a man whose testicles had been cracked like an egg.

“One more for good measure.” Amy bit her lip, cheeks flushed, nipples visibly stiff against her tank top.

*SQUELCHHH\*

This time she really put her weight into it.

The door rattled in its frame. Bruce let out a guttural, agonized howl that echoed through the room, his whole body convulsing as searing pain tore through his groin. Tears leaked from the corners of his eyes.

Amy finally stepped away from the door, leaving the string still taut but no longer yanking. She walked over and gently cupped his aching, throbbing balls in her soft hand, feeling how hot and swollen they were.

“See? That wasn’t so hard, was it?” she whispered, stroking him teasingly through the pain. “Maybe next time you’ll think twice before pranking your sister.”

Bruce could only gasp and whimper, head hanging forward, chest heaving.

“You’re… insane…” he managed weakly.

“And you’re going to remember this every time you sit in this chair from now on. Sweet dreams, Bruce.” Amy leaned down and kissed his sweaty forehead.

She slowly removes the tape restraints from his wrists, before moving down towards his balls, and as she reaches for his balls, she notices a small wet pouch leaking through his boxers.

“Damn.. Looks like I ruined his orgasm. Oh well! He’ll heal up soon.”

As she removes the string from his testicles, Bruce instantly falls down cupping his balls and writhing on the floor in agony.

“Well.. Whenever you’re done crying like a little girl, you should go ice up those boys, ok?” Amy says as she twirls her hair one more time, before leaving out the room.
