Something had come over Alex as he stared at the titanic, twitching mounds of his mother's enormous rear-end. She merely smiled down at him, aloof, as her ass enchanted her son. Her huge cheeks would bind and break him, and make sure he fit between them. He could almost see a space for his tiny body to fit in, deep in the warm, crushing depths of her ass. Her cheeks undulated again, and his space was gone. "I belong in mom's ass." He said, and marched into that gigantic maternal buttcrack.
"Haha! I knew it! I'm so proud of you sweetie!" Their mom crowed. "Samantha, be a good girl and get my phone. I want you to take some pictures of this."
"Okay mom~" Samantha sighed, upset with losing her little-big brother to their mom's big ass. She reappeared with the camera and began deftly snapping shots of her brother's humiliation.
"Now, are you sure you want to do this sweetie?" Abby said, ever-so-slightly spreading her enormous cheeks and looking back at her little son with a grin.
"Yeah ... yeah this is - this is where I belong mom." Alex said solemnly. The darkness of his mom's ass-crack was beckoning him. He belonged in there, being reduced to zero in the warm, foul-smelling depths. Being forgotten by the world, the little boy between his mother's buttocks. He took one last look at the outside world, at the bright lights and varied colours, before plunging himself face-first into his mother's ass-crack.
Above him his glorious mom bit her lip in trembling ecstasy. The day she had been waiting for years to arrive was here at last! Ever since Samantha had given her a mother's day present of Alex's unwilling face to sit on for a day she had been desperately awaiting for him to shrink down to 6 inches! If it had felt that good to sit on her son's face for a day, imagine how electric it would be to have his whole body inside her butt-crack for the rest of his life!
"How does it feel sweetie?" She breathed, eagerly allowing him to make his way into her deep, dark butt-crack at his own pace.
"I feel ... at home, mom." Alex said after just a moment's hesitation. His mom's building-sized buttocks pressed gently against him as he delivered himself deeper into them. It felt like they were welcoming him, an errant turd, back home to the place he belonged.
"Mmph!"
Breathing became difficult for Alex as his body finally completely disappeared between his mother's gelatinous butt-cheeks. It was warmer than he thought, but uncomfortably so, and though his mother's buttocks were large and soft they pressed against his body tightly. He was made uncomfortably humid and uneasy by the inquisitive squeezing of the warm butt-sea around him. They were almost testing him, to see how much he could take. They knew it wouldn't be much.
Reaching a soft, dark space somewhere deep up his mother's ass he pressed his nose to a buttock and hesitantly inhaled, filling his lungs with the stench of his mother's odorous ass-crack. She giggled as he gagged on the stench of his new home. "Is it stinky, sweetie?" She said, clenching her cheeks possessively around him. The smell was much worse than when Samantha was merely sitting on his face.
"Mmm, isn't it great sweetie? Normally around this time a boy like you would be getting to know girls for the first time. But instead you're getting squeezed to death by your own mother's mighty ass-cheeks!
"Y-yeah ... mom..." Alex barely managed to squeak in response, but his tiny voice was muffled and lost between the pounds of maternal ass-flesh.
"You know, you should be happy sweetie!" His mom gasped, grinding her hips, "I'm way hotter than any girl you could get in school! My breasts are a GG-Cup after all!" She laughed, jiggling those massive jugs happily for Samantha, who dutifully snapped some exquisite photos.
Though he knew his mom was right - she had made sure he got a face-full of her generous cleavage on more than one occasion - Alex knew as well he'd never even get to see them again. His mom might've teased him with her massive breasts when he was regular-sized, but now his place was here in her gigantic ass, and she was never going to take him out again.
As if to punctuate that point, his mother began squeezing her ass-cheeks with renewed vigour, crushing his little body like a bug. Curled up in the fetal position, naked and with her divine derriere pressing in from every angle Alex simply endured his mother's crushing ass-torture for what seemed like hours. Remember - you belong here, he told himself. Mom is my Goddess, and I'm here to worship her enormous ass. During a prolonged squeeze, Alex pursed his lips and pressed them in abject reverence against his mother's ass-cheek. Mother and son held that pose for a full minute, both letting the position define them - mother; glorious and dominant, rendering divine judgment on her unworthy son with her glorious rear-end - son; beaten and submissive, accepting the crushing reality of his ignominious life in his mother's bottom. Finally he heard her beautiful voice cut through the pounds of packed ass-meat.
"Want me to stop, sweetie?"
He felt his little ribs give in and his skull groaned forlornly under the pressure of her buttocks, as if it was certainly about to crack. He whispered "N-no ... mom ... k-keep going..."
His mother laughed uproariously and crushed his body between her aggressive cheeks.
"Nnnn. Oh, yesssss...." She moaned huskily, her divine derriere rhythmically squeezing her son. Her broad hips gyrated as if she were on top of a man, but it was only her little son, and he was being squashed by her massive buttocks.
He tried to breath but his mom's crushing buttocks wouldn't let him. A ragged gasp escaped his lips as her maternal cheeks crushed him back into unconsciousness, her roar of satisfaction echoing in his ears...
