(end of part 3)
I grabbed Jeff by his baby stiffie and led him toward my room. When we walked in, we saw my little cousin Nate sitting on my bed in his yellow footy pajamas playing with my Xbox. I felt Jeff's boner go soft almost instantly.
"Hey Nate," I said.
Nate turned his head and saw us in our birthday suits, my hand of Jeffy's shrunken dinkie...
(beginning part 4)
"Whoa what are you doing?" Nate asked.
"We just took a bath," I said.
Nate seemed satisfied with the answer and went back to his game.
"Could you sit on the floor and play?" I said. "I have to diaper Jeff."
"Ok," he said, hoping off the bed. Then it hit him. "Wait, he wears a diaper?"
I nodded.
"Why?"
I looked at Jeff but he stayed silent so I said, "Because he likes fu..."
Jeff interrupted me, "Cuz I pee the bed sometimes."
Nate laughed. "But you're 13."
"15," Jeff corrected him, red faced.
"Hey Nate, when was the last time you peed your bed at night?" I asked.
He shrugged, "I think when I was like 7 but that's only cuz someone pranked me."
"What about the last time you peed your pants in the day time?" I said.
"Umm... I think in nursery school." Nate answered.
"So not since you were like 5?"
He nodded.
"Jeff still does."
Nate's mouth opened in disbelief. "In the day time? No way!"
"Yup," I said. I pointed to his underwear on the floor, "See for yourself."
"Haha he still wears cartoon undies?" Nate asked with a laugh.
"Answer him," I ordered.
"Yea sometimes," Jeff meekly replied.
Nate picked up the undies. "Ewww, they're wet."
"Told ya," I said.
"Nasty dude," he said.
"What?" I said.
"He poopied in them too!"
"I did not!" Jeff said, defensively. "They're just skidmarks," he added quietly.
"Haha no you're 15 and you poopied in your pants!" Nate taunted.
"I bet you get skid marks too!" Jeff said, trying not to cry.
"Sometimes but not like that!" Nate said.
"Why don't you prove it?" I helpfully suggested.
"How?"
"Come here."
Nate came over and I unzipped his footy pjs and he stepped out of them. I pulled down his baby blue boxer briefs and held them up inside out. There was a small skid mark about 2 inches long and a half inch wide in the seat.
Then in the other hand, I grabbed Jeff's undies and held them out. There were two huge skid marks covering almost the entire rear of his cartoon briefs and several smaller ones in the part between his legs. With the yellow stains in the front, you could barely see any white cotton.
"See!" Nate said triumphiantly. "My poopy stain is little cuz I know how to wipe my butt. Yours is like 1000 times bigger."
"So you think he should wear a diaper?" I asked.
"Sure," Nate said. "You don't want him to poopy your bed."
Jeff turned his head.
We stood there for a few seconds, all in the buff, when I noticed Nate staring at my boner.
"You like it?" I said.
"Yea, it's really big."
"Kinda."
"How come it's so big?"
"Well," I said, "cuz it gets bigger when you get older."
"Will mine get that big?"
I nodded and that seemed to make him happy.
"Will I get hairs around it when you get older too?"
"Sure."
Now he looked confused.
"What?" I asked.
"Umm... if it's bigger and hairier when you get older, how come his is the same as mine and he's older than you?"
"Well a few people stay like little kids for a long time but almost everyone's gets bigger and hairs on it."
"How do you know I won't?" Nate asked.
"Cuz you're already bigger than him."
"No he isn't!" Jeff yelled.
That was a mistake on Jeff's part. Nate's was soft and Jeff's was mostly stiff. I went to my backpack and got a ruler out of it.
"What's that for?" Nate asked.
"We're going to measure to see who's is bigger," I said.
"Ohhh..."
"Rub yours," I said to Jeff and he took his dinkie with his two fingers and rubbed it to full erection.
I noticed Nate saw what Jeff was doing and did the same. "This feels nice," he said.
"You ever do that before?" I asked.
Nate shook his head. "No. But sometimes I rub it on the bed."
"Not on your teddy bear?" I asked.
Nate looked at me weird and Jeff turned redder than red. "Ewww... plus I don't have a teddy bear anymore. I'm 10 and a HALF," he said.
"Jeff does and he's 15," I said. Jeff turned his head away but Nate still looked like he thought I was joking.
I went back to Jeff and took his hard little 15 year old peepee in my hand and stuck the ruler against it. "2 1/4 inches," I said.
I went over to Nate and put his stiff 10 year old dink against the ruler. "3 inches," I announced. "Nate's is bigger."
"No way!" Jeff said, "You're cheating."
So I made him come over and look at the ruler.
"Why don't you put them together to compare?" I suggested.
So Jeff grabbed his weenie and pushed it against Nate's. Jeff was really small for his age and Nate was kinda tall for his so they were almost the same height.
It was clear that the 10 year old's bald stiffie was a little bigger than the 15 year old's. Jeff started pushing against Nate and Nate responded. My cock was a semi before but seeing them rub their little kid dickies together boned me up something fierce.
"Nate, when you rub your dink against the bed, does it feel good?" I asked.
He nodded.
"How long do you do it for?"
He shrugged, "Til I get bored I guess."
"You wanna try something else that feels good?"
"Sure!" he said, excitedly.
I told him to lie on the bed on his back and he did. I left his legs over his head.
"What are you doing?" he asked nervously.
"Jeff's gonna put his dink up there."
"Is it gonna hurt?"
"Nah," I said. "Jeff's is so tiny it prolly won't hurt."
He still seemed nervous so I added, "If it hurts, you just say so and we'll stop."
"Promise?"
"Promise."
"Ok."
So I grabbed Jeff's arm and yanked him toward us.
"You know what to do, slave," I whispered.
Jeff got to the edge of the bed and spread Nate's butt cheeks. He tried to push his little 15 year old stiffie into Nate but he had trouble. He could get it near the hole but not actually in. It was made harder by the fact that Nate's butt had a little padding and so did Jeff's belly. He tried again and it seemed to go in but the first time he thrust, it came out. Jeff's dick was so tiny that Nate didn't even make a sound or motion when it entered his virgin ass. Jeff tried two more times but again couldn't get it in. So he just started rubbing his dick up and down Nate's crack. It only took about a minute and a half for Jeff to dry cum. Nate seemed to be enjoying it too.
I ordered Jeff to get up and he did. His post-dry cum dink had shrunk to almost unseeable. Nate was still stiff.
"Sorry Nate. Jeff's weenie is too tiny to do that."
"That's ok," he said. "That felt good."
"I know, but still you should try doing it to him."
I pushed Jeff on the bed and he lifted his legs over his head, like the submissive bitch he was. Still, he needed to be reminded who was in charge.
"Turn over!" I said.
"Huh?"
"Get on your hands and knees and shut up!" I ordered.
He quietly did and spread his cheeks obediently, his ass at the edge of the bed.
Nate walked over to him but wasn't quite sure what to do, which I thought was cute. So I grabbed his boner and guided it towards Jeff's awaiting hole. When it touched, I told Nate to push and he did. He got all three inches inside Jeff's ass. Jeff moaned like a girl. Nate's face looked like he was enjoying it too.
"What do I do now?" Nate gasped, his eyes closed.
"Just push in and out."
It took him a few times but he quickly got the hang of it. Jeff groaned every few thrusts. I hopped on the bed and start whispering in Jeff's ear.
"You're being fucked by a 10 year old... that's all the sex you'll ever get because your dick is too tiny to fuck anything yourself... do you like being fucked by Nate's big 3 incher?"
Silence.
I grabbed his hair, "Well?"
"Yes," he said between groans.
"Yes what?"
"Yes I like being fucked by Nate."
"By Nate's 3 incher which is bigger than yours even though he's only 10."
Silence.
I grabbed his hair again.
"By Nate's 3 incher which is bigger than mine even though he's 10," he mumbled.
He was groaning louder so I grabbed the dirty undies and shoved them in his mouth. He took them out of his mouth and started smelling the skid marks and pee stains while starting to stroke his own mini dick.
"Damn freak!" I said, starting to rub my own hardon.
"I'd better stop soon cuz I'm gonna pee," Nate said.
"No," I said. "Keep going... faster if you can. Trust me."
So Nate increased his pace, fucking Jeff's teen ass even fast with his little 3 incher. Suddenly, Nate's body stiffened as he dry orgasmed into Jeff's ass.
As he pulled out, I noticed a drop of fluid on the tip of Nate's boner.
"Damn," I said, inspecting it.
"I told you I had to pee," Nate said.
"It's not pee, buddy. It's cum."
"No way," Jeff said, sitting up.
I wiped the tip of Nate's dick and smeared it on Jeff's face. "See! The kid's only 10 and he came in you. Maybe one day, you'll be a big boy like him and sperm too."
"Does that mean I'm a big kid?" Nate asked.
"Sure does," I said, patting him on the back.
Nate smiled proudly and Jeff, suddenly self-conscious, covered his pricklet.
I pushed Jeff back on the bed and he knew to assume the position. I spread his cheeks and pushed my 5 1/2 inches into his ass. I leaned forward as I was doing him and whispered in his ear. "You like having younger guys fuck your ass, don't you?"
His eyes were closed but he nodded.
"Did you like being fucked by a 10 year old?"
He nodded.
"Do you wish your weenie will be as big as his some day?"
He turned red.
"Say it," I pulled his hair.
"I wish my dick will be as big as Nate's some day."
I thrust harder. "You don't have a dick. You have a weenie."
"I wish my weenie will be as big as Nate's some day."
"Do you like smelling your piss and shit stains?"
He nodded.
"Do you do that when you rub your little weenie at home?"
"Yea," he whispered.
"Every time?"
"Most times."
I grabbed the undies again and shoved them in his face. He smelled and them and rubbed himself as I was plowing his ass.
I felt Jeff's body stiffen and he moaned loud as he had another dry cum. His hole tightened on my cock and that pushed me over the edge. I stiffened myself and put several big squirts of cum up his poop chute. I lay there for a minute on top of him as the remaining sperm dribbled out of my softening cock. Jeff lay below me, his face resting in his dirty underwear pillow.
I pulled out of Jeff and grabbed his undies to wipe the remaining juice off my dick.
"What's that?" Nate asked.
"That's called cum," I said. "That's what that little drop of stuff was on yours. That's what makes you a big kid."
"And he can't?"
"Nope."
"But he's even older than you?" Nate said.
"I told you, he's a baby. That's why he pees and poops his pants and that's why he has to wear a diaper."
I grabbed a towel and laid it on the floor.
"Lie on the towel," I ordered Jeff, who did without a word.
He covered his now soft, microscopic weenie but I slapped his hands away. "Don't worry, we all know your peepee is baby size. That's why we're putting a baby diaper on you."
I motioned for him to lift his butt up and when he did, I slipped the small "adult" diaper under his baby ass. I grabbed some wet wipes and wipe Jeff's dirty, cummy ass nice and clean. I gave Nate a few and he wiped Jeff's hairless peepee and nuts.
I tape the diaper nice and tight and told him to stand up. He looked ridiculous: a 5 foot 2 inch kid wearing a diaper. I grabbed my phone and took 2 pictures of him.
"Pee in it," I told him.
"Huh?"
"Use your diaper."
"No please..."
"Piss in your diaper or I'll send the pics to your brother and everyone else in my contacts list."
He looked horrified. "But I don't have to go bad, honest!"
I had an idea. "Lie on the bed," I ordered him.
He did, warily. Without warning, I jumped on him and started tickling his belly. Jeff is the most ticklish person I've ever met. He was screaming like a girl so I shoved the shitty undies in his mouth. Nate thought it was hilarious so he started tickling Jeff's feet. Jeff reached down to pinch his dick so I tickled his underarms.
After about a minute and a half, I stopped. Jeff felt limp, his resistance ended. I stuck a finger down his front. It was wet.
"Hey Nate, feel this. Jeffy peepeed his didee."
Nate stuck his finger down there too and started laughing. Jeff turned over on his stomach and tried to cover his head. Though I noticed the underwear was still on his face.
I heard my mom's car rumble into the driveway.
"Hey slave," I said to the big baby. "I've got a chore for you to do."
(to be continued)
Feedback welcome. I already have some ideas but I'd love to hear other people's suggestions about what should happen. I don't guarantee I will use all of them but I'll read them and hopefully use some.
