Boop boop, I should be asleep.

Enjoy, I own nothing, reviews are nice!

"Butters, I don't know about this. What if I have to go to the bathroom?" Eric asked while they were both in his room getting ready for the school day.

"Then you can take it out and go to the bathroom. But that's the only time you can take it out," Butters answered.

Cartman had his pants down, his bare ass in the air as he leaned against his desk for support as Butters stuck a vibrator bullet inside of him.

"Now let's see if it works," Butters said, a controller in his hands.

"AH!" Cartman screamed, his arms collapsing underneath him. "Don't put it on high so suddenly," he gasped, his head buried in his forearms.

"Eric, you're going to have to have better control if you want to last the whole day," Butters said, turning off the vibrator.

Cartman turned to look at him, tears in his eyes. Shaking, he made himself stand up straight.

"You can still back down now," Butters told him. By way of answer, Cartman pulled up his pants and zipped himself up. "Okay, don't forget the rules. You can't take it out unless you have to go to the bathroom, you can't excuse yourself to go to the 'nurse's office,' and you can't cum on school grounds unless the last bell has rung. And if you lose you'll have to go to the motorcycle rally with me in Denver this weekend."

"And if I win, you'll have to be my slave for a month and never talk to me about motorcycles ever again," Cartman said, a little cocky. He was certain he was going to win.

Butters grinned and flipped the vibrator on.

"Aaaah!" Cartman fell down onto his knees.

"Let's go, we're going to be late," Butters said, heading out.

Cartman looked up in time to see Butters walk out the door. He was gripping his carpet tightly and bit his lip. There was no way he was going to make it.

. . . . .

Cartman was in science class scribbling notes when he snapped his pencil in half.

"You okay?" Stan asked him when he saw Cartman grit his teeth.

"Yeah, I'm fine. Just a weird stomach pain," he said, rubbing his stomach.

"You should go to the nurses office."

"Nah, it's cool. Just give it a minute to pass."

The vibrator was at its lowest setting, and soon Cartman was able to get use to it. Butters was in English at this hour on the other side of campus, was the controller really that far reaching?

He dug another pencil from his backpack and focused on the lesson like his life depended on it. After another minute the vibrations stopped and he sighed in relief.

. . . . .

Cartman and Butters are in German together. The teacher called Eric up to the board so he can correct sentences she had written on the board, but before the chalk and board made contact, another wave of vibrations hit him and he dropped the chalk.

"Eric, are you okay?" The teacher asked.

"Yeah Eric, are you okay?" Butters asked from his seat, a huge smile on his face.

Cartman turned around to see him, and then the teacher. "I'm fine, I've just been having stomach cramps all day, but it'll go away soon."

He bent over to grab the chalk and made another attempt at writing on the board. The vibrations became stronger and he hit his forehead against the board shut his eyes.

"Eric, I'm sending you to the nurse's office," the teacher said.

"No," Cartman said, shaking his head, his voice husky. "I'm fine."

Slowly he made the proper corrections on the board and went back to his desk. He sighed in relief when he sat down again and Butters smirked at him. The vibrations were gone.

. . . . .

"Dude, are you okay? You've hardly touched your lunch," Kenny said, sitting across from Cartman, who was looking down, his hands in his lap. The vibrations were on at full blast.

"Poor Eric's been having stomach cramps all day," Butters said sympathetically as he rubbed Cartman's back. "You can have his lunch, he probably shouldn't be eating anyway." Butters pushed Eric's tray across the table towards Kenny, who readily accepted the offer.

"Thanks, man. I hope you feel better," Kenny said before biting into Eric's burger.

"Whatever," Cartman mumbled.

. . . . .

Cartman was sitting at his desk during math class, his final class of the day. He was staring at the clock, willing it to go faster while he had to face the onslaught of vibrations. Butters was changing the speed so quickly it felt like Eric was being hit by bullets, and he didn't think he was going to make it.

"Okay class, well I guess I'll just let you out five minutes early. I'll see you tomorrow," the teacher said after handing out the assignments. "Oh, and Eric, don't come to class if you're feeling sick. I could tell you weren't paying attention."

"Okay," Eric gasped. He stood up, gathered his things, and was the first one out the room. Butters was right behind him.

"In here," Butters said, grabbing Eric's hand and leading him towards the janitor's room.

"I've won," Eric said, breathless, once they were inside.

"The rules were until the last bell rang. We still have three minutes," Butters told him, putting the vibrator at full power.

Cartman crumbled and fell onto all fours.

"I can only imagine what it must have felt like having that inside you all day. And everyone saw your aroused face, that's pretty naughty," Butters said, watching Eric squirming. "Two minutes."

Cartman squeezed his eyes shut and gritted his teeth. He was trying to hold off but he knew he couldn't last those final minutes and he was going to cum. Just when he thought he was finished, he felt the vibrations slow and then stop completely. He looked up at Butters.

"It stopped," he gasped.

"Aw, did the batteries finally die?" Butters whined. "Well, they sure did last a long time."

Right then the final bell rang. Eric smiled and then started laughing.

"Ah haha! The final bell! I did it! I won! I don't have to go to your stupid rally!" He stood up, triumphant, but his legs were trembling and he had to hold onto the wall to support himself.

"Dammit," Butters muttered. "A deal's a deal, I guess." He stepped forward and lovingly cupped Cartman's groin. "I think the winner should be rewarded."

Cartman was leaning against the wall as he hoisted Butters onto his waist and entered him. As he pumped into Butters he felt the vibrations start up again and he came instantly.

"Holy shit," Cartman gasped, sliding down to sit.

"Guess there's still some battery left in the vibrator," Butters purred, kneeling in front of Cartman and kissing him.

"Did you let me win?" Eric asked between kisses.

"You were so cute today, telling everyone you had stomach cramps, you deserved to win," he giggled.

"That's not fair, I didn't want to win like that!"

"Who cares, you won."

Eric pulled Butters into his arms. "We'll go to the stupid rally and you'll still be my slave for a month, how's that sound?"

"Sounds good," Butters said, kissing him.

"Now can I finally take this fucking vibrator out?"

Butters laughed and nodded his head.
