Bad boys get punished! (could be a series)

"So...Tommy? You wanna try that again? 'So-rry.' Two syllables. 'So-rry'! It's really simple!" Sam said as she smashed her foot into my exposed balls, sending shockwaves of agonizing pain throughout my whole body and making me shiver and shake in fear.

"Shurrey! Um sho shoory! Pweas shtawp!" I cried and moaned pathetically into my gag, made of wet panties and socks she had previously used. I had only groped her friend's ass jokingly at class. I didn't know she would punish me so harshly! With my hands tied behind my back and my legs chained open on both sides, there was nothing I could do but cry and plead into my gag and hope this would all end soon.

"Hm?? What's that? It sounded like you were trying to tell me something but for some reason I can't seem to hear it clearly." She said as she played with her long blonde hair and teased me with her foot near my balls. She faked another kick, making me flinch and wince in anticipation, then another, then another, then another. Each time, I couldn't tell whether she was going to follow up on it or not, and the uncertainty made me feel completely helpless, even more than I had already felt. Instead of a kick, she gave me a low punch that bounced my package so fiercely, I thought I was gonna throw up from the pain.

"Awww, did you think it was gonna be a kick? Well, here you go. Bonus kick!" She said after she followed that strong punch with a jumping kick and kept her foot raised into my balls, pressing for impact.

I started weeping and squealing terribly. "Shuuurry! Um sho shoorrrryy hohohohoooo" I kept crying and weeping like a newborn baby.

She giggled and said "hmm, maybe I should help you out." Then she took off the gag, now even wetter with my saliva. "Eww, this is disgusting!"

"Hah hah hah haaaah I'm sorry I'm so sorry. Please no more I beg you! I won't ever do it again! I'll do anything for you just please don't hit me anymoooore!"

"Hmm well it's not me you should apologize to. Cindy. Cindyyyy!" She called out to her friend who I had groped at class. "Let's see if Cindy believes you"

"I'm so sorry miss Cindy! I won't ever do what I've done ever again. I'm so so so sorry please forgive my foolishness and stupidity. I'll do anything just please let me go!" I breathed heavily and tried my best to plead and beg pitifully through my tears.

"Hmm you want me to forgive you? Should I? What guarantee do I have that you won't do this to any other girls?" She said as she stepped closer and grabbed my balls firmly but without squeezing. "How does it feel to be groped back? Huh, you fucking piece of shit? You sorry excuse for a human being?" She squeezed them little by little increasing the pressure.

"I'm so sorry please have mercy! I won't ever ever do it again!" I said as I cried and my words became unintelligible through the pain and fear I felt.

"I have just the thing to ensure his obedience, Cindy!" Sam said as she emerged from behind Cindy with a thick metal ring. "You put this around his cock, and you have this remote in your pocket at all times. Whenever he misbehaves, ZAP! Heheee don't you think it's fun? Look at his face!"

They both laughed sadistically as I moaned and screamed "No NO NO PLEEEASE NO!"

"You're making too much noise! The gag shoulda stayed on." Sam said as she stuffed my mouth with her panties and socks once again as Cindy attached the device to my cock and slapped my balls hard.
