Stewie's Diaper Change

Here's the much delayed Chapter 2. The end is rushed, because I lost a lot of the oomph I had when first writing it. There's about a month break between me beginning this chapter and me finishing it and it shows :( Hopefully 3 will be better.

=================================================================


Stewie and Brian sat in the living room, watching TV. It was mid-afternoon, Peter was at his job, Lois was doing errands, and the kids were at school. So this left Brian to stay at home with Stewie. This used to be unbearable for both of them, but in the past weeks, they had found a way to pass the time they both enjoy.
Stewie was just in his diapers. Brian had starting taking all the rest of his clothes off as soon as Lois left, to give him easier access when the mood struck.
“Brian…I feel we should switch it up today. I’m tired of being on the bottom of your humps”, Stewie said taking his eyes off the TV to look at the canine, “I feel like I should be able to give every once in awhile, week after week of being on the bottom has led to some really awkward diaper changes with Lois”.
“There’s a reason you’re always on bottom, runt. Your dick’s the size of a pen cap, even if you could penetrate me, I wouldn’t be able to feel it. It wouldn’t be fun for either of us”, Brian quickly responded back, laughing slightly, not believing he was saying that.
“I do understand that, mutt. I wasn’t implying that I would stick my appendage into such an unclean posterior. And if I did, you should be honored that that future ruler of the world is even trying to copulate with your anus, my seed is going to be very valuable in the years to come, you watch!” Stewie shouted in a rather loud outburst.
Brian was, by now, laughing quite hard. He looked down to Stewie, finally taking his head away from the TV. “Squirt, you can’t even…squirt…yet. Call me back in a few years and I’ll try to care”.
This took Stewie aback, for he truly had no comeback to that. Instead, he decided to change the subject. “You know, Brian…I wasn’t talking about sex between us anyway. You’ll never guess what I found while spying upon the matriarch earlier today.” Stewie made his greatest attempt to have a sultry tone in his voice when saying that. “Wait and see!” He giggled as he got up and ran upstairs.
Brian went back to watching TV, wondering what type of implement Stewie could be fetching. He didn’t have to wait long as he heard the small pitter-patter of the baby’s steps running down the stairs. He obviously had something stuffed into his diaper, as it was making a very large bulge and the back end of it was peaking out the top of his diaper. Stewie ran to the couch, sat down, and pulled the surprise out of his diaper. It turned out to be a very large dildo.
“What do you say to that?”
“That thing is atleast 12 inches long!” Brian gasped, but he wasn’t intimidated. He was more shocked the Lois played with such large toys.
“Well…how about it? Wanna see how it can go?” Stewie asked, looking up at Brian, almost begging.
Without even a word, Brian got off the couch. He took the dildo from Stewie and positioned it where he had been sitting, so it was positioned where it would be if someone was sitting there. He positioned himself in front of the dildo. With one paw propped on the couch to stabilize himself and the other at the base of the dildo to make sure it didn’t move, Brian began to suck it. For the few times, he would only go about 4 inches down. But after that, he began to take the entire 12 inches down his throat with no problem. He began to gag, tears welling up in his eyes and saliva dripping down the rubbery appendage.
Stewie was watching in amazement. He had never known Brian was such a good deep throat. It couldn’t have been his first time. But ignoring his amazement, Stewie stood up on the couch and took his diaper off. Brian noticed this and stopped giving the dildo the blowjob of it’s life. He instead focused on the naked baby standing on the couch. He looked at the babyhood of his owner’s youngest child. It couldn’t of been more than 2 inches long, and it was fully erect. The sack below it was still empty, as he was still waiting for the guys to come dome. Pulling his gaze away, he looked at the dildo. It was totally covered in his slobber. He laughed a little bit at the show he just put on.
Stewie then grabbed the slobber covered dildo in both his hands and jumped off the couch. He positioned himself directly behind Brian. In this position, Brian’s anus was almost exactly equal to the bottom of Stewie’s head. Stewie stared at the puckered flesh in front of him for a few seconds, and after gazing at it, he ran a finger over it, but not penetrating it. The sensation of Stewie’s index finger running over his anus made Brian shudder, and it also caused his pucker to flex in and out a few times.
“Brian…you clean yourself, what…6 times a day, right?” Stewie asked
Brian, unable to discern Stewie’s intentions responded “Well, 6 times is a bad day. It’s usually more like 12---“ Brian’s speech was interrupted when he felt a small, slimy thing touch his anus. It didn’t take long to realize that it was Stewie’s tongue! He didn’t say anything and just enjoyed the feeling.
Stewie was lapping at Brian’s anus like a cat at a bowl of milk. After 10 or so long licks across the surface, he stuck his tongue out deeper and pushed it into Brian’s anus. He noticed a slightly sour taste as he did this, but it wasn’t anything as bad as he was expecting, and he continued. His tongue pushed its way as far as it could into Brian, and Stewie then moved it around, bathing the entrance to the dog’s bowels in baby saliva. After 20 laps in and out of Brian’s ass, Stewie stopped. Without warning, Stewie grabbed the still saliva soaked dildo and positioned the infront of Brian’s now well lubricated anus.
“Do you want it?” He asked Brian
“Oh yes!” was the response from the now very horny Brian.
With that, Stewie pushed the head of the dildo in. He watched as the canine’s previously tight anus stretched around the girth of the dildo, which was probably around two and a half inches. When the head was fully in Brian, he pulled it out, and shoved it in again. He wanted to loosen him up. He kept pushing the head in and out. By this time, Brian was fully aroused. He looked down at his length, proudly protruding from his now engorged sheath. Every time Stewie shoved the dildo into him, it caused it to smack against his stomach, which he realized was almost as good as masturbating. Brian closed his eyes and enjoyed the feeling of the massive penis in his ass and his fur masturbating himself for him.
This continued for around 10 mintues, by this time the dildo was easily sliding in and out of Brian’s now extremely loose anus. Brian could feel himself getting ready. When Stewie thrust in again, he couldn’t hold himself any longer. In an instant, spray after spray of white canine juice was shooting all over his fur, the sofa, and the carpet. Noticing this, Stewie shoved the long dildo as far in as it could go, making Brian’s orgasm much more intense and getting an extra shot of jizz from him.
Stewie kept the dildo as far as it could go until Brian’s orgasm was over, and then pulled the entire length out. As he pulled the head out, Brian’s ass was left gaping, far enough for Stewie to see far into the dog’s colon.
Stewie looked at the panting dog, worn out, with his engorged knot still hanging out from his sheath, and said “So…what next?”
Brian smiled, flexing his very relaxed anus a few times, and said “Oh, I have an idea."
