A\N: Is anyone else noticing the lack of images in the stories profile? This site is getting wacky from time to time.


It was a nice sunny day in quahog as we zoom in on a yellow house with a bright red door that is home to one of the known families, the Griffins.

Not everyone enjoys the classic feeling of going on a road trip as the moment for vacation. Some say it's a waste of time or too old school for the new generation who can't spend two minutes without their cell phone, but Lois wanted her family to be more on the open so for some bonding time they would go on vacation with said road trip. Not that everyone was having the same excitement though, Peter was just packing away a bunch of stuff which was meant according to him to...Not having a boring as heck trip on the car.

"Okay, everything is packed up in the trunk Lois." Peter said as he just closed the door and got into the driver's seat.

"Peter! Don't you think you brought too much stuff? I don't think everyone will fit in their respective seats" Lois asked him.

"What are you talking about? We have all the stuff we need for this trip," Peter said, not really getting what his wife was saying due to his ignorance.

"Dad! There is only enough space here for one of us" Meg said.

"I should go, I'm a big boy and need space" Chris said with his arms closed.

"Oh. my. god. Can we not do this cliche of two kids going blah blah because of a seat?" Peter was annoyed "How about this? Chris is going to sit on the last seat and Meg will sit on his lap. Then the two of you will be nice and tidy up with no barking back"

"WHAT?" Both talked.

"Uhm...Don't you think that is going to make them feel a bit Awkward?" Lois raises an eyebrow.

"Oh c'mon Lois, their sibling's what's the worst that can happen? At least this way they won't be able to make a fuss over nothing'' Peter said, not thinking for a moment that his two kids were already adults full of hormones.

"Alright, Peter, just try not to kill us before we get on the road," Lois said as she put on her seatbelt.

Meg and Chris look at each other annoyed...or so one would think, it's more of embarrassment that they were being forced to do something like that.

'Geez...is she really going to be on my lap? That's weird' Chris thought.

'That fat bastard is always doing this, why do I need to sit on Chris's lap? Do I look like a kid?' Meg thought, annoyed.

The two young adults were hesitant about getting in the car but Chris decided he wanted to just get this over with so he could get to the hotel faster.

"Is the hotel any good?" Lois asked.

"Yeah I looked it up and it had a bunch of good reviews online. alright everyone in the car now" Peter demanded.

Meg huffed before getting into the station wagon and sitting on her brother's lap.

Chris shrugged knowing nothing would come out of it and is the one to get inside first, then Meg just huffs in annoyance before getting in the wagon and sitting on her brother's lap...the latter contorting his face for a few seconds for...unknown reasons.

"Hey, dad how far away is this hotel again?" Chris asked hoping he would be out of the car within the next hour or else he would be in a much more awkward situation.

"Oh just one One hour and thirty minutes"

"Whew okay" Chris said relieved that it wouldn't be too long.

"But that's if we don't run into any bad traffic," Peter said.

'OH CRUD!' Chris mentally cursed.


*Ten Minutes later...*

"See Peter I told you not to pack all of that stuff we would have beaten all of this traffic by now." The milf said as she looked at the highway that was filled with cars.

"Well, Lois maybe if you didn't annoy me so much with this silly vacation I won't have to put so much stuff to keep me entertained" Peter said annoyed at her.

"What? Why are you fat!"

While the two were bickering Chris was thinking to himself. Even though Meg was treated like unpopular girls do in school and call ugly, she had one thing that made her stand out...her ass. It was so big and jiggly like someone cut a beach ball in half and glued the still air-filled parts to her buns.

If someone asked if Chris was sexually attracted to Meg he would quickly say no but...He couldn't deny that her ass was one of the best you could ever see and now? Meg was forced to sit on his lap, truly Chris could feel how heavy it was and since their father's driving skills were awful it made her booty jiggle against his crotch from time to time.

'Shit! Shit! Shit! Damn it, Meg, how can your booty be this tempting?'

Chris tried but failed...miserably in trying to control himself. His boner rose up from his pants in such a way that not only has it warns Meg that something big and hard has appeared behind her, but it got lodged between her ass cheeks, which ended up giving an involuntary buttjob every time the car moved too much and made her booty quake.

''What the! What ar-"

Before Meg could talk Chris held her mouth muffling the voice "Shhh..keep it down, mom and dad maybe be noisy but try to talk low" Chris whispered to her.

"Why the hell is your dick out Chris? Can't you wait until we get the hotel to take care of your personal business?" Meg whispered to her brother.

"It's not out Meg, it's still within my pants. I'm just currently having a boner and the fabric is being stretched out" Chris whispered before another ass bounce happened thanks to the road.

"What do you mean it's stretching?" Meg whispered to her brother as her father hit another bump.

"It means that what your feeling right now is my boner...still under my pants"

"How the hell is it that big?" Meg asks, embarrassed that she is bouncing around on her brother's boner.

"Because that's just how it is Meg. You're the one to blame, gosh why is my Sister the one with the best ass in town? That's just unfair"

"You really think I have the best ass in town?" Meg asked.

"I-I mean" Chris started to sweat.

"It's okay if you tell me Chris" Meg whispered to her blonde-haired brother.

"W-Whatever, pay attention to the front seat or they get suspicious" Chris changed the topic.

"...This isn't over yet just so you know" Meg whispered, closer than what was comfortable for Chris.

'I never felt a dick that big so close to me before. It's so...warm and twitchy'

Meg thought, feeling how her brother's cock was by far the alpha dick of anything she has seen even on porn movies. Truth be told as well, Chris was just her idiotic fat of a brother who spent time just being silly and perverted, but she would be lying if that sudden change wasn't making her a little bit...turn on. It reminded her of that sinful day on the Halloween party where they only made out heavily and nothing else, it was gross at first but tastes can change.

'I wonder how much he can take it before succumbing to it'

Chris thought that the traffic would be his salvation, no more bumpy ride because of the awful driving skills of Peter, but now something else was unleashed and it would not show him mercy until the words she wanted to hear came out of his mouth.

Meg grinded on Chris's erection without her parents knowing since they were focused on the road and their own conversation.

Since her parents were too focused on the road and their own conversation, Meg decided to test her brother and began by grinding her fat ass on his erection.

'What the hell?' Chris gasped.

"What? I'm just trying to make my seat a little more comfortable." The brown-haired woman whispered to her brother.

'This little bitch...' "Whatever, but don't do it too often" Chris said, annoyed.

"I'll try," Meg said in a teasing tone.

"You Better" Chris bit his lower lip, staring at her now slightly exposed panties.

'When did she start wearing lacy style panties?' the fat teen asked himself while looking at her black panties.

''Something wrong? Perhaps seeing something you like?" Meg asked.

"Um, I'm m-maybe." The blonde said as he was trying very hard to control his hormones.

"You won't mind if I keep moving right? I still want to hear it from you, how much you like my butt" Meg said with a teasing smile.

"Come on Meg can't you just stop without me admitting that you have a nice ass" Chris said before covering his mouth.

"Why thank you, Chris. I could never know my posterior was so" She gets up slightly before sitting back "Gorgeous"

"You are so evil." Chris groaned out in a low tone of voice so his parents wouldn't hear him.

"Oh c'mon little brother, don't you like your Sister bonding with you?" Meg said, grabbing her pants and showing a little more of her panties.

"This isn't bonding this is called torture" Chris said to his older sister as she showed her lacy black panties.

The blonde-haired teen was getting annoyed, she knew that he was a guy full of raging hormones and that her ass was doing things to his crotch, but what does she do about that? Teasing the shit out of him, that bitch. He should teach her a lesson for acting all high and mighty.

Chris decided to be bold and grab her ass causing the brown-haired woman to smile.

"Oh my~Someone wants a little bit of ham?" Meg asked with teasing.

"Keep acting like that and I do much more, think I'm joking? That I stop here?" Chris said seriously.

"Oh, I encourage you to explore more" Meg said as she rubbed her ass on his lap.

If Meg was actually trying to see if he would go any further he didn't know, but Chris was not going to let her do this. Being really bold he puts his hand inside her pants grabbing a handful of her meaty booty and feeling her panties as well.

"That's more like grabbing that meaty ass of mine," Meg whispered to her brother.

His sister's ass cheeks were so soft, far better than any alternative lonely virgin boys would use to try and cope with their lack of women. Would she still act like that if he did a little deeper of a test?

''Your a little horny bitch Meg'' His fingers reached to her sacred place ready to attack "And I'm going to show you to not mess with me"

Before she could ask what he meant by that, Chris quickly covered her mouth in case she moaned too loud for what he was about to do, and since his parents don't give a damn about them it would be easier.

Chris slipped a fat finger into her tight pink wet pussy. "Mmm you seem to be wet down there aren't you?" Chris said into her ear.

Meg's eyes widened like saucers, her brother just stuck his finger in her cave, it was sudden and rough and she didn't know how to feel it at first so he was left to play around.

"I told you not to tease me now I'm going to enjoy teasing you. I could keep you on edge and stop just before you cum." Chris said as he fingered her pussy.

The teen girl struggles for a bit before melting on his touch, after all, she was just like any other girl her age. Horny and needy for boy attention and he was quite good with his hands, all Meg could do was blush and try to muffle her moans.

''I'm going to take my hand off now, try to be natural little sister''

"You take your hand off and I'm going to continue to tease the shit out of you until we make it to the hotel" Meg said with a little venom in her voice.

"And why would you stop? You forced my hand Meg, so the least you can do is shake that bunch of pork you have for a booty. Let's see who lasts longer" Chris was now into this game.

Meg and Chris were now in a battle of teasing, seeing how long it would take the other to cum, one of the best ways to spend the time until they arrived.

Chris decided to put another one of his fat fingers in his sister's pussy and pleasure her.


* Sometime later*

"Hey, we arrived!" Peter said happily.

"Finally I can now take a nice hot shower" Lois said as she got out of the car and stretched.

The pair of idiotic married coupe didn't notice but Chris and Meg were trembling in pleasure on the back seat. The blonde-haired fat teen bust a nut on his pants while the girl gushed in her panties, they had just masturbated each other in their own ways and now this was the problem that would, later on, be talked out.

"G-Give me a moment dad I-I be coming soon" Chris said.

"Yeah we'll be in there just a little bit," Meg said, trying to keep her face as regular as possible to avoid alerting their parents.

'Don't take long, your father tends to get lost in big places like a little kid" Lois said.

"No, I don't!"

"Peter, you got lost in the Disney world after running right in," Lois said to her overweight husband.

When they were gone, Meg looked at them. Her brother and I spoke.

"We need to talk"

"Bathroom first?" Chris said.

"Yeah sure let's go" Meg said as she got out of the car and quickly pulled her jeans up before anyone could see her.

The two of them were now inside the hotel bathroom, no one was around and the door was locked.

"Ok, what the hell was all that about? You teased me!" Chris said.

"Hey you started it by getting a huge hard-on from my ass" Meg said as she swayed her hips while walking to him.

"Well excuse me, I'm a hot-blooded teen. Just because you're my sister you think you were free from my urges?"

"I thought so but apparently I have a very good reaction to you" Meg said as she leaned into her brother.

"You mean how you made me ruin my underwear? Seriously, Meg, you shouldn't tease a guy like me. I'm in a phase where masturbation is the only way to get myself off because girls don't like me enough to let me touch their bodies"

"Well I will gladly let you touch my body as long as I can touch yours as well" Meg said as she laid hand on his bulge.

Chris is left speechless "Meg are you insane? We can't do this, and in a public place no less''

"No, but I'm horny. It was taking everything in me to not pull your pants down and ride you in the car." Meg said.

"R-Really?" Chris looks at her.

"Maybe we were made for each other, you have the tool and I have the cushion"

"I guess we might be. Are you sure you really want this?" Chris asked.

Meg turns around and does the only thing she knows that will tell him what she thinks. Bending over and slapping her booty as it wiggles, smirking, and licking her lips.


"No point hiding our freaky nature now"

*Meanwhile...*

"Peter, do you think Meg and Chris are taking too long?'' Lois asks.

"Nah they're fine we can leave their key to their room at the desk and they can pick it up when they are done" Peter said as he grabbed Stewie who was still sleeping.

"Yeah, it's not like they would be banging each other's heads right? They sure can be a bother, just wish they could be more like good siblings"

The husband and wife went up to their room to rest from the trip.


Back with Meg and Chris

Meg was on her knees staring at her brother's huge cock for the first time in her life.

"Shit! It's really big, I want to slurp every nook and cranny" She said, starting to stroke its mast.

"Go ahead and try. I'd love to see your face when you can't swallow all of it." Chris said not knowing Meg has been practicing for years.

"Then I will show you the skill I have been polishing to the day I got myself a boyfriend" Meg opens her mouth and firstly...swallows the tip first.

Meg swirled her tongue around her brother's huge tip of his cock which she knew was the most sensitive part of a cock.

"Oh shit!" Chris already started touching her head.

'Oh, the scent of this fat cock is driving me nuts.' Meg thought as she slurped on his head.

"Hmm~Please go deeper" Chris moaned, just wanting to face fuck her right there and now.

Meg obliged by forcing almost half of his cock down her throat thanking God he didn't give her a gag reflex.

'Showtime!'

A big cock like that was a worthy opponent, it tasted bitter and it forced her jaw just the way she loved, Now Meg will make Chris bust another nut, this time on her stomach.

Meg grabbed his huge balls that were filled with cum and gently massaged them with her hand while sucking on his

"OHHH! AHH! F-FUCK! You're so GOOD! At this" Chris moaned like the horny boy he was. Clenching his fist on the stall support.

"I've had years of practice with something similar to this" Meg said before going back down on her blonde haired brother.

She sucked him real good, sloping sounds could be heard of the beanie girl sucking off her brother anaconda, it twitched in anticipation for the blast that would come, the warmth that filled her body, its scent. Chris would eventually move his hips and fuck her mouth like an onahole.

"Oh god, this might be the best way to start a vacation." Chris groaned out as he fucked his sister's face.

His fat balls slapped against her chin as Meg would drown herself in his dick if this keeps going, if not already happened.

'So big and warm, twitchy, must have more'

Meg went at almost breakneck speeds trying to get Chris to cum down her throat.

"AHHH IM NUTTING!"

'Yes fill my mouth with that cum.' Meg thought as her brother shot rope after thick rope of cum down her throat.

"AHGN! I love you, Meg!"

"Mm I love you too Chris" Meg said after swallowing all of the cum her brother shot in her mouth and throat.

"Hold yourself against the wall, it's time to make this go full throttle"

Chris watched as his sister turned around and pulled her pants and panties down to her ankles to show off her ass in full glory.

"Glorious" He started rubbing it "Soft and sexy" Then a big slap.

"Awhn!~" She moans.

"So jiggly too." The fat male said as he watched her ass ripple from the slap to her ass.

Grabbing his member, Chris aims at the one thing he wanted the most, now it was time to give Meg a taste of his spear.

"Your mine now sister, prepare for what you didn't get on Halloween"

"Please give it to me." Meg moaned out as he slid his cock into her wet dripping pussy.

"OHMPH!" He slammed it inside.

"Oh my God, your cock is huge." Meg moaned as he slammed his cock in and out of his sister.

"Fuck! Your pussy is so tight, it's wrapping itself around me ahang!"

The moanings coming from there was so loud that anyone who got near, quickly backed away not wanting to know what was happening there, and those who tried were stopped by the locked door.

"I'm going to ride this huge ass all vacation" Chris said before smacking her huge ass causing it to ripple.

"OH! YES, Oh yeah Chris, spank my ass more, treat me like a bitch. Breed me!" Meg was loving this, it made her really horny.

"Oh, I am going to treat you like the bitch you are," Chris said as he reached under her shirt and grabbed her tits.

The stall walls moved in sounds like someone was banging the outside with hammers, like two wild dogs were in breeding season and they were going to stay at it for a loooong time.

"This is probably the best thing dad's stupidity has ever brought us." Chris moaned out as he fucked her.

"Y-Yes" Meg clenched her fists and grits her teeth.

"God your ass is so soft and natural unlike some celebrities" Chris said.

"All-natural bro, and all yours. So do your best and fill me up deep within and brand it as your property" Meg shakes her hips.

"I'm going to enjoy ruining this pussy so no one else will be able to use it but me" Chris said.

The blonde-haired boy kicked to high gear and fucked her pussy harder and faster than anything in the world, she was now his toy to let out stress, his cum dumpster of a phat ass sister.

"Yes, just like that. Make sure you ruin my pussy especially for that pathetic nerd Neil." Meg moaned as Chris's hips met her thick meaty booty with each thrust.

"Oh c'mon it's not like you seeing him ANYMORE EEE!" Chris was ready to blast a fat nut inside her.

"I know that but every week he still asks me to go out with him" Meg said as she felt Chris's cock throb in her pussy.

"IM CUMMING!" Chris said holding onto her hips and letting a final thrust.

"Me too little brother." Meg moaned out as she came on her brother's cock.

"AHHHHH NNNHHH!"

*SPLURT!*

"Ups!" Peter said, letting some of the fondues on the floor.

"Damn it, Peter, I told you to not put that much of it. Now, all that goo is on the floor, I'm not cleaning that up" Lois said.

"Oh don't worry Lois I'm pretty sure they have a custodian in this place to help keep it clean" Peter said as he ate the piece of cheese.

Some time had passed and the siblings had already returned from their heavy session of bonding, it had been intense, but nothing a shower 'together' did to help freshen up.

"Hey, their guys," Chris said.

Meg and Chris already took a shower, they are supposed to be getting inside the same place Lois and Peter are, maybe a place to eat cantine?

"Hey, sweetie hey Meg what took you guys so long? We've been waiting for you for almost an hour." Lois said as she looked at her children.

"Yeah we Uh... *Ahem* Meg got stuck in the bathroom and I only realized that after the battery in my phone died when I was done playing some dump games. You know how my attention span is" Chris said.

"Oh okay well now we can finally order some food." The orange-haired milf said as she sat down next to her husband.

"I'm telling you guys, spending the week here is gonna be lots of fun," Peter said.

"Yeah, we are going to have loads of fun. Aren't we Chris?" Meg asked her brother as she looked at him.

"Sure will Meg"

They sat down and secretly rubbed each other privates under the table showing that the fun had just begun.
