A\N: I like to think artist such as Grigori,Maxtlat and Arabatos do the best thicc pics. Also wow! So many reviews i did not see that coming :D i try my best to make the chapters worth it.


Being the Dog it's his job to protect the house while the family is not home but in this case it was a little different,for you see Peter had made a family vacation and they ended up forgetting about Meg like always,but Brian the dog was also at their house since going in vacation with Peter was never nice. The daughter of the house was used to that crap and saw instead an opportunity to call her friends to spend the weekend on the house and have a good time with her real friends, Brian did not care about that at all...after all Meg and her Friends had hit a Growth spurt last year that made them be...quite exquisitely thicc.

*6:00 PM*

The Dog was reading the newspaper on the couch while the girls were somewhere around the house.

"Hmm...Looks like Peter and the rest of the family got arrested. Welp they will find a way out eventually" Brian said getting up from the couch.

The day was so boring,he had nothing to do besides walking around teasing machines that were Meg and her friends. Such thickness around the house and he could only admire from a safe distance,thinking back on it Brian always had a luck for at least having sex with beautiful woman,sure serious relationships were a pain in the ass but at least he would fuck them,Maybe he can get a bigger peek at Meg today she must be on her room.

"Screw it i might as well go with it"

Saying that Brian decides to go upstairs slowly going towards Meg Room to see if she was still there. Approaching the door cautiously its possible to hear a faint music...the song was familiar to him it was Iggy Azalea-Mo Bounce song. Meg felt really confident and self esteem had grown on her besides her body and you know what that song means.

"Lets see"

Brian starts to peep at Meg room by the keyhole, and doing that he sees the pink beanie hat user do what he never thought she would. Twerking! Yes that's right Meg Griffin was twerking her ass who had grown to be a pretty big and round booty that Lois would feel really jealous by the fact she doesn't have one.

"Ohhh yeah this is awesome, i cant believe how it feels so good" Meg said.

She was shaking her ass up and down as later it would ripple in sexyness waves moving it from left to right,she didn't care how freaking big it was as long as it was BIG and sexy.

'Damm Meg ass is amazing,i wish i could grope and sniff some of that meaty cheeks just once' Brian thought.

While he was too distracted staring at The Griffin girl Tush someone slowly holds Brian Shoulder with making him almost yelp in surprise but another hand covers his mouth

"MHMP?"

"Turn around slowly" The voice said

When he looks to the other side Brian eyes go wide,right there was Patty one of Meg friends second to Esther and Ruth. The nerd girl with the secret sexy body who Boobs and ass got Bigger at the same time giving her a curvaceous figure of sexyness of equilibrium...also he was just busted.

"What are you doing exactly?" She asked with one of her eyebrows up.

"Nothing...i was just making sure the place was safe" He lied

"Safe? Don't you mean staring at Meg Butt?" Patty said

"Now why would you think such a thing?" Brian said smiling

"Because...your not wearing any pants so i can see your dog penis erected" Patty said

The dog looks down and indeed he was having a raging boner,his big dog cock twitching with urge.

"Oh...fuck ok listen,i know this i-"

"Shhh quiet it,you don't want her hearing us right? Lets just go to her parents room for now"

Patty said holding Brian hand going to Peter and Lois room while Meg was twerking all she wanted.

"Ok...why did you bring me here? I could just go to the bathroom"

Saying that the dog looks back at Patty who is sitting down on the edge of the bed looking at him with a smirk.

"Because Brian…"

She starts undoing her shirt buttons taking it out revealing her pink push up bra that opens in the front.

"I wanted us to be alone for this moment since last time we had no chance" She said undoing the bra letting her girls out to breath,pink nipples looking erect and skin looking a healthy lush.

"W-what? Are you...you know what? I'm not questioning it" He said.

"Good Dog...now come here" She said.

Without losing any time questioning The two were already going at it in Meg parents bed, Patty was laying down on her back allowing Brian to grope her tits as much as he wanted,the left nipple would be his targeted for sucking while the right one it would be for slightly giving pinching making her moan while her sensitive buttons were being taking care of.

"Ahhnnn!" She moaned

"Hmphmm y-your breasts are amazing Patty" Brian said slurping her nipple.

She loved how he sucked and pinched her nipples but Brian erection was demanding attention so it was time for her to lose her pants and panties showing of her luscious Big booty to Brian. The nerd girl then positions herself on the bed in four swishing her butt left and right.

"This booty is yours Brian" She smiled

"Ohhhhhh Boi!"

The dog was hella excited but before he even plow her with his member he decided to just pretty much stick his nose there. Patty Moaned in pleasure while her pussy was getting licked by his tongue while her other hole was being sniffed by Brian dog nose which was a weird but arousing sensation,he was actually focused on giving her pleasure and not just for himself,the taste was amazing and it felt like it had been five minutes he was there doing the foreplay what stopped him was when Patty moaned loudly spraying her juices of her first orgasm all over his face.

"Ahhhhhnm! S-so good" She said

"Ups looks like i took my sweet time huh? Don't worry now i am hard enough to show you how dogs fuck" Brian said giving her ass a slap making it jiggle.

Climbing up next to Patty hips and holding around her stomach Brian aims his throbbing big cock and since her pussy was wet and sensitive it would be a slippery joy. Slowly inserting it inside her pussy made both lovers of this affair to moan in pleasure feeling each other, Brian had fucked many womans in his life but to fuck a eighteen year old teenage girl? It was a guilty joy he wanted to pat himself in the back,it felt like he was Quagmire which annoyed him but he soon forgot about it by Patty humid vagina walls.

"Yes! Yes! Yess!"

Patty was now enjoying herself having Brian humping her from behind holding around her waist not letting go for anything, motions of in and out of her hole was going at a great speed that the dog had the urge to fuck her after so long,he hated to admit but he was a pervert,since the day those girls and Meg got new bodies he wanted to fuck them all.

"Ahhhhn yeahhh! More"

Later on they change positions and Brian was between Patty Legs fucking her missionary style giving her pussy all the humps he could muster,fucking her hard with grunts and sweat on their bodies,time seem to have no meaning for them at that point,only the bed creaking and moving from the sudden intense moment.

"AHHN! B-Brian do it! Deep and more!" She said moaning loudly with her tongue hanging out of her tongue.

"AHHHHHHNMHMH!" Brian moaned.

The dog moaned letting out his first sperm blow of the day that him somehow got under control,filling Patty womb with his seed she moaned feeling her getting stuffed.

"Ahn...ahnn...ahnnnn" She moaned.

"That. was. Great" He said.

Brian had just had sex with patty on Lois and Peter bed were they sleep all night...yeah he felt no regrets, screw them it's not like he would stop himself if he could OR wanted to. After their session of sex Patty decided to use the room bathroom to wash herself while Brian said he would have to leave before anyone could see them or ask for him. Patty nodded and soon Brian left the room.

But there was one problem...his dick was still hard.

"Damn it Bulbus Glandis your making this erection hard to go away,i mean even after that orgasm i feel like it won't go away yet. Maybe if i use some cold water"

Brian was passing by Meg room at that moment and this time no music was heard but her door was half opened and like some sort of classic cartoon, when he pass by it a hand quickly yanked him inside the room.

"Whoa!" He said

The inside of the room had a mysterious vibe. The window was closed and the curtains as well,the lights were out and only the light of the computer illuminates the room enough for Brian to see Meg.

"Heeeey Brian"

"Meg? W-what did you do that for?" he asked

"I heard some weird noises coming from my parents bedroom and when i took off my twerking time i saw you and Patty fucking each other hard,how naughty of you" She said looking down at him.

"W-well you see this is because…" he didn't really know how to answer.

"You know Brian i never saw you having a erection as big as this one,maybe i would not be able to give you one since that time we were a thing for a short while and i got a little obsessed but…"

Then she turn around and bends over showing her huge voluptuous ass in her tight blue pair of pants looking like any slap as light as a baby hand would make it wobble.

"How about now? Do i excite you?"

"HECK YEAH! I mean..y-yes but your not...are you?" He asked sort of knowing were this was going.

"Get on bed Brian...now" She said more serious before getting back up.

Swallowing some saliva brian does as she said afraid that Meg would decide to be more violent,he know how strong she was when snapped. Now on the top of the bed He takes a look at Meg staring at him sexily,then she started to take out her clothes in a sexy way. Meg tits had grown some too but its not as much as Patty and the AMOUNT Ruth had for herself but they were pretty hot anyway,taking out her black laced Bra she liked so much revealing the already erect pinkish nipples to Brian. Then turning her booty towards him she started removing her prison like pants meanwhile shaking her ass left and right while taking it off,it was a sight to behold how it jiggles so much as the fair skin of that booty starts showing up.

"You like the view Brian?" She asked before dropping her pants down showing that she was not wearing any panties and now her huge ass was at show.

"Ohhh Meg...Its so sexy" He said with eyes wide.

"I'm glad you enjoy it because now i am going to show you what these buns can do"

She said walking backwards ready to park her big booty on Brian cock who sees it up close,when it actually gets it between those cheeks.

"Ahhhn..ahnn! Ahn! Ahnnnn" He moaned like nuts.

"It's too soon to moan like that Brian,you also have a nice dick here i can feel it moving and struggling hehehe"

Meg said that enjoying having his cock between her buns like a hotdog hearing Brian moan like she always wanted since that day in the prom,now She was hot enough to do anything more confidently. The Griffin girl starts moving her ass up and down in motion doing the famous move only big butt girls can do...a Buttjob! Every move made the dog moan at this level of smoothness of skin and also skill,her hands would wrap around her own ass to smother it some more to Brian heart content but everything needs time and she was done later on.

"Ok Brian that's enough booty for your penis,now it's time for the next level" She said

"What do you mean?"

"Oh your gonna love it!" She smirked.

Later on Meg is standing over her bed letting Brian Have a nice under vision of Her valley of Booty.

"W-whoa" He said looking at it as hugeness is the word.

"Your not tall enough for a sixteen nine so i gotta go other ways oh and one more thing...Try your best not to suffocate"

She said the last part lovely as Meg descends her Big thicc booty on Brian face with a thud engulfing his face on ass were only muffling sounds come out.

"Hmmmmp! Your face makes a comfy seat,now lets see"

Her hands start to go onto The dog shaft,beginning by stroking his hard member up and down with one hand while the other goes to his balls slightly squeezing them,his moaning is audible under her booty seeing that is enjoyable. Meg was loving this a lot,feeling his breath on her ass and dominating him like that was great of a feeling,she was gonna make him feel he never had someone as good as her.

"Yeah you like this you filthy dog? You want me to milk your dick?"

She said making twisting motion moves on his member like she was actually twisting but was just a motion,then stroking and rubbing the sausage with both hands while moving her ass on his face,She could feel him twitching but she had no intention of leaving him cum right now so she has an idea. Removing her beanie hat she was still using a tiny piece of cloth like a ribbon was taken and then using it to wrap around his cock making a knot that would prevent him to unleash, Brian moaned louder feeling his dick getting tighter.

"Now now Brian don't be such a quick shooter,you're just about to actually have a taste of the ass"

The big booty girl removes her ass From Brian face leaving him to breathes the air once again,it was sure a good booty and he slurped all of it as he could but damm! The air was important too.

"W-what are y-you gonna do?" He said between breathes.

"I am going to ride you hard!" She said looking deep in his eyes.

The dog gulps again meanwhile Meg positions herself for the Reverse cowgirl style lifting her ass up and ready to put his member inside her he saw her big once again it was,he never got tired of saying how thick and big it was and now that she was going to ride him that way it could be saw all the while she fucked.

"Are you ready to fuck this hole for real this time?" She asked

"Well i t-"

The dog was interrupted when Meg landed her ass hard on his dick putting the whole thing inside her PUSSY! Which was really wet so it was not as tight but that didn't prevent the moanings.

"AHHHHHNNN FUCK!" Brian said

"OHHHH YEAHHH! It's this! This is it!" Meg said.

The whole room was now filled with the sounds of not just Meg and Brian moaning but also the sound of Meg booty cheeks clapping.

*Plap plap plap plap plap Plap plap plap plap plap Plap plap plap plap plap Plap plap plap plap plapPlap plap plap plap plapPlap plap plap plap plap*

The Bed was shaking and moving,it seems Meg was more aggressive then Patty,the fact his knot also hot inside her only to make it more hot for her she rides him like no tomorrow.

"AHNNNN BRIAN! YES! AHHN! FUCKKKK!" She moaned loudly.

"HAGNGNGN! L-LET ME CUM!"

He begged now really being able to take a horny Meg while his dick was prevented from cumming. With a huge grin Meg stops the riding for a moment,sweat dripping of her body while her hand undoes the ribbon holding a grip on his dick.

"Now...LOAD ME!"

Was all she said before moving again with her riding which was all Brian needed to Howl like the dog he was and cumming inside Meg womb wildly while his tongue was the one hanging out while Meg was drooling and yelling yes to the skies.

"Ahnn..wow that...was awesome" She said.

"Y-yeah i-it was" Brian said

After the fucking session Meg removes Brian dick from her pussy with a few...moves better not saying that way even with the dog knot came out easier. Nothing too hard,Brian got out of Meg room after she got the sex she wanted from him and now he was walking on the hall again feeling the after fuck with her.

"Ouch! Man that girl is nuts,she fucked with me dick real good"

Brian had a huge cock and big balls which was one of the reasons he had more sex with beautiful woman then any dog his race can get,and by that i mean talking ones. Now he had an idea,the girls on the house probably would want to have sex with him as well because of that,here why Meg and Patty were so easy. Maybe….

"I think i am just going to take a shower,i am sweaty"

Saying that the white fur dog goes to the bathroom of the house wanting to get a shower and maybe get rid of his erection that won't go away for some reason now. While inside he hears humming and is surprised to see someone already inside the bathroom taking a shower who its figure is covered by the bath curtain. But it's Obvious who it is since her *ahem* Chest stands out.

"Ahhhn such nice shower"

The girl in the shower was Ruth the puffed cheek girl who used overalls as a fashion,she had become so busty it was like two basketballs were hiding under her shirt if you had no plan on believing her jugs were actually so HUGE!

'I should probably le-'

"I know you're there Brian" She said calmly

'W-what?'

"You think i cant smell the scent of labrador after sex?" She said the weird fact.

"Well that's sort of a weird thing t-"

"Hush!"

Ruth said moving the curtain away revealing her naked body wet by the water and glistening. Her tits were even bigger when with no layers of clothes hiding them and her nipples were slightly bigger,god what s view.

"Get inside here now Dog or your regret it dirty dog"

With no other option besides the latter Brian decides to just cooperate with the sexy big breasted girl and get inside the shower, were now that he stops to think it was a real close up of her breasts,being able to stare at them like that was like turning his brain off and restarting it.

"You like them? I know everyone else who stares at me either with jealousy or desire do" Ruth said smirking bending over a little to let her tits close to his field of vision.

"Y-yeah they are...really big"

"Spying on a lady while she is taking a bath is not really gentleman like Brian,now your going to have to take responsibility"

The brown haired girl said getting on her knees in the bathroom floor face first to the Dog raging erection.

"Punishment?" He said knowing well what was next.

"Behold the power of breasts Brian"

With that said Ruth lift up her huge tits with both hands and wraps them around His shaft like a sandwich.

"Oh shit!" Brian said moaning afterwards.

The softness of those jugs were out of any other pair of tits hr has ever felt in his entire life with female humans. Hugging her own boobs like she was trying to prevent his dick to pop out from its cell of soft flesh and smothering even more, is that the shaking starts,Ruth moves her tits up and down pumping it as both of them let out moaning of pleasure leaves their mouths.

"Hmmm! Ahhhnmm! Ohh god"

"Enjoying the Titfuck? I heard Dogs can get hard for one hour because of their bulbus glandis or whatever maybe as long as there is sexual things happening?" She said

With that done Ruth opens her mouth and starts putting some of his dick in to suck around the head with her tongue,sucking up and down and licking like a lollipop Ruth enjoyed the pleasure she was giving and the warmth such moment was giving her,giving a titfuck to a big dicked dog on her friend shower ? what a rush!

"Hmppmmmhnn" Her voice was muffled because of her mouth being busy.

"Ahhnn i cumming! Ruth IM CUMMING!"

Brian said Accidently turning on the shower again getting them wet and then a orgasm was released from his member hitting the back of Ruth throat making her swallow some of his sperm but since it was a lot she decides to let the rest come out plastering her tits and face with his white substance while moaning a lot,the water slowly taking away the thick sperm.

" ahnn….agnnn...ahnn Man that was...what a blast" Brian said

"Hmm you taste quite different Brian"

"T-thanks?"

"As much as i would love! To have more time with you i think i should clean myself before Meg sees us so i think you should leave,but if we ever get some quality time alone again i be sure to give you more service" She said giggling with a smirk

'Yeah but i already fucked Meg and Patty so…'

Leaving Ruth to do her own Thing Brian was enjoying the fact he was having so much luck with the thick ladies,but also was getting angry because his penis was still hard.

"Maybe it was a bad idea to take Stewie Supplements he made for horses...that baby has too much free time" Brian said.

"Fuck!" Someone said.

" Hmm? Something is coming from Chris Room"

Saying that Brian goes there to investigate what the noise was all about,once his hand was on the doorknob he opens it to reveal...

"Ok what is going o-Esther?" He said.

Esther was Meg friends and she was a black chick and she was one of the girls who had a growth,said girl was changing and she's having trouble with pulling her pants up her butt...you know why? BECAUSE HER ASS IS FREAKING BIG! Like 60 inches of ass! That's bigger than Meg ass! For fuck sake talk about Big black ass of a phat booty.

"Brian?"

"Oh...sorry i guess i should had knocked"

Esther looks down to see Brian erection still there like it didn't just fuck a lot like the animal he is.

"Did you come here because you wanted to peek at me?" She asked

"Oh! Well no you se-"

"Awesome! Boys are finally getting into me,having this freakingly large ass is not so bad after all"

"Wait what?"

"At first i was thinking it was just going to be annoying and hard to buy pants this size but now i realize this is the step to get onto any Boy i want" She said sticking he fist in the air.

"That's...great"

"Say Brian can you do me a favor?" She look at him smirking.

Meanwhile down the first floor someone rings the telephone and a message is left on the voicemail.


"Hey Brian Stewie here,The fat man has ruined our vacation and we are gonna stay here for a while just saying,if things get out of control i am ditching them! So there is some food on the closet and don't mess around with my time machine i swear it,if i found another hooker ending up on the moon again i lose it...see ya buddy"


After the message ended we go back to Chris room Were Esther now completely naked is riding Brian cock on Cowgirl. Her huge black ass bouncing up and down on him like a stuffed toy not stopping for even a minute,her pussy engulfing his whole member like its second nature to her,she had lost her virginity before but it was so long since that,now going wild on a dog swollen member with such vigor was her hobby now.

"AHNNNN! HANN! AHN! YES! I always wanted to know how it feels to get plowed by a dog! Animals fuck harder then humans!" Esther said while moaning.

"AGHHH! OH MY GOD! Your ass is so damn heavy i think it's going to break my pelvis"

"Don't be a wimp Brian this is just getting good"

"Who your calling a wimp? If you had been my first fuck of the day it would be different"

The dog said groping all the fleshy meat of that phat ass while moving as much as possible for his body size which Esther took gladly. Chris Bed was strong since it was for fat guys like him but even it was shaking a lot.

'HMM..guys please come back soon,i think these girls planned to kill me with sex'

That was all Brian said before once again Cumming as much as possible inside Esther womb having the bed Succumb to their weight and break the legs.

"AHnnn...yea now that is the stuff" Esther said

"I think i finally got Limp" Brian said dizzy

"Care to do this again tomorrow?" She asked

" …...Yes definitely"

That Night Brian got rid of the worst case of horny dog he has ever faced,it was painful after all that sex but oohhhh it was worth it.
