Charlie's throat was sore from trying to scream to be let out. He had finally given up yelling, resigning to his fate as inhabiting his step-sister's gigantic behind. She had put some leggings on now, to keep him in place. Like her mother, her bottom was too big for any pants that could be bought at a store, only custom-made. Carmen strutted around with extra confidence, knowing that her step-brother was wedged between her fattened cheeks, being pushed around as her massive rump bounced with every step. She couldn't help beaming, thinking that his whole world had been reduced to the valley of her ass. Served the little loser right. His whole life, he had never had a girlfriend or a good job, so it made the most sense to keep him in her ass. He wasn't going to be useful anyways, so she reasoned, if he could help me out by constantly stimulating my anus, that would be the best situation for both of them... well, her at least.
For Charlie, it was torturous, stuck in between those giant, strong cheeks which held him in place like a vice. The smell was a constant cheesy odor which he breathed in through the day, trying to keep his head as far from her anus as he could. Sometimes, if she was feeling extra cruel, she would "adjust" herself, standing up and separating her cheeks, forcing him into the very depths of her ass and clenching him there, his face pressed against her anus. She loved hearing him cry for relief, but his cries would be quickly silenced by an emission from her backside. As soon as she broke wind, his cries would be silent. She grinned, feeling she submission set in over him, as, after a pause, she began to feel his little tongue licking around her anus.
"The two of you are going to become best friends, Charlie," she whispered to him. "Lovers, even. You will never have a real lover; the closest you will get is my asshole. So you will come to love it in time, and you will learn to crave it's smell, it's taste, it's gifts."
Charlie shook his head, sobbing as he continued to lick her slick anus, the bitter taste becoming unbearable.
"Charlie, I know you will become addicted to my ass in time," she said, her hand on her hip, speaking over her shoulder. "You always were fascinated with my butt from the beginning, and now I've given you what you wanted. A new home, in the very place you love the most. Now, Charlie, I have some good news and some bad news for you."
Charlie listened intently. He was more focused on the good news, as he couldn't see anything that could be worse than this.
"You will be getting to come out of my butt, Charlie. A little vacation from your new home," she giggled. Carmen was recording the whole conversation on her camera. Her website subscribers had more than quadrupled since word got out about her shrinking her stepbrother.
Charlie's heart jumped with joy. He would be leaving this humid, stinky cave! He felt that if he just had a chance to speak, he could convince her to bring him back to normal size, that he could please her more than ever in exchange for never shrinking him again.
She pulled him out, and immediately fanned her face, crinkling her nose with mock disgust.
