Maddys Butthole has its first guest! My Family & The Shrinking Virus chapter 6 by TheGiantGambit

Maddy looked down at her half inch brother contemplating what his first punishment would be. She had dreamt of this moment for months now. Getting her hands on her first tiny was her biggest dream come true. The fact that this one was her older brother the size of a bug made it even more exciting to choose which method would best fit his punishment…

Without speaking a word Maddy licked her index finger on her opposite hand and poked her tiny brother with it, adhering his tiny body to the tip of her finger. Maddy then shifted her hands downwards towards her waist band. She felt Mathew begin to intensely struggle and scream as she allowed her night shorts to drop on the floor along with her panties. Maddy then bent over her brother's bed and brought her hand around the back of her body, holding her brother right outside his little sister's ass.

Mathew looked on in horror as his sister's giant white ass cheeks were fully exposed to him. He had watched over the past year as his little sisters butt ballooned in size from her workout regiment. He couldn’t help but notice just how massive it had gotten even recently. His friend at one point teased him about its massive jiggly size… Mathew thought it was gross when his friend talked about it but had secretly stolen looks at it on multiple occasions, something that Maddy had at one point noticed…

“How's my ass looking back there Matty? I know it probably looks like a giant moon huh? Only this moon has a giant crack in it! Among other things too… My ass got so fat so quick these last several months. I love how much power it has over men, they see my big thighs and plump cheeks and it's over, they’ll do anything I tell them. I bet you love it too, huh little brother? You couldn’t resist its draw even if you tried, your human nature gets the best of you doesn't it?” Maddy shook her cheeks back and forth letting them jiggle and shake around in front of her brother as she laughed at his horrified face…

“Well bro because you can't seem to follow basic instructions from your new Goddess I’ve decided your first task is to clean my asshole! It's fitting, I mean, YOU'RE an asshole so it makes sense to rehabilitate you I'd have you clean up an asshole! It’s like poetry!” Mathews' screams and cries intensified as he tried to free himself from the skin of his little sister's finger pad. His tiny size was no use for this, so he decided to yell instead.

“MADDY LET ME GO RIGHT NOW THIS IS NOT HAPPENING YOU LITTLE SHIT PUT ME DOWN RIGHT NOW!!!” Mathews' words somehow didn’t convince his sister to reconsider the inevitable. She laughed down at him, still stuck on her finger unable to free himself from the view of his sister's God-like rear shaking in his face. “OH I'M THE LITTLE SHIT? HA! Let's see how you like that choice of words here in a sec Mattyy.”

Her ass finally stopped shaking as she reached around her back with her free hand, grabbing her left cheek and pulling it open, revealing Maddy's giant brown hole puckering out at her brother looking on from just outside her cheeks. Mathew cried as he stared into the abyss of his sister's ‘exit’ hole pulsing in front of him in the distance in anticipation…

“Awwww whats the matter Matty? Scared of a little butthole? Hmmm so fucking pathetic… If it makes you feel better this is my first time putting anything in there, so consider this a new experience for both of us! It’ll be a good bonding experience! You go in there and squirm around in my ass, and I’ll do my best to not let my butthole crush you! Deal?” Maddy brought her brother face to face with her hole, rubbing him in the tight knot that formed her giant asshole. “Kiss is Matty, tell it you love it, lick your Goddess clean!” Maddy laughs, pushing him harder into the surface of her wrinkled sphincter. She could feel his tiny movements as he desperately struggled to push the beast in front of him away. His struggles only fueled Maddy’s enjoyment. She pushed harder again, letting her finger slip slowly beyond the folds of her hole…

“Bye bye big bro! Do a good job in there! Or else we’re gonna need to make this worse for you!” Maddy gave a last push submerging her finger inside her tight anus, she let out a moan, feeling the pains of a first time anal penetration. However the sensation that followed was incredible. 

Mathew was shoved within his little sister's bowls. As he propelled past the threshold of her folds his body finally lost its grip on her fingertip and he fell to the ground beneath him. To his abject horror the ground was sticky and wet, pulsing when touched. The walls around him were covered in brown goo and ahead of him he saw a mass in the distance… Maddy did not let those touches go unnoticed. They sent vibrations through her body as she pulled her finger back out leaving her once big brother trapped inside his sister's ass…

“Oh yes… God you feel amazing actually! I see why people pay thousands for little shits like you Matty… I bet it smells for you though! Giggle Also umm, this should probably be a given but watch out for last nights dinner down there... I know you're a 'little shit' but that doesnt mean I wanna make you one yet!” Maddy laughed hysterically thinking of her brother being crushed by her poop… Mathew heard all these words echo throughout her body as she spoke. From where he was inside her, her words really did sound like God speaking down to him from the sky beyond. Mathew ran to her closed sphincter and began punching as hard as he could trying to get it to open up. This had the wrong effect as he felt her body shake again around him.

“Oh god I'm not gonna be able to focus, little bro, with you being so obedient in there!” Maddy teased as she began getting dressed again. Mathew fought but it was no use, he screamed and shouted up at the walls around him as they pulsed and gurgled around him. Maddy paid no mind to the faint squeals and banging. She had two other family members she needed to check on, and now that her brother was in his place, she could focus on breaking in her parents next… This day was just getting started...
