After a good several seconds of looking at you, your mom's mouth formed a smile. You didn't know why she thought this was funny, but she had definintely seen you. She leaned forward in her chair and called to Betty.
"Betty!" She said.
"Yeah?" Your giantess aunt asked, turning around to face your mom.
"I think I found Ben." Your aunt began looking around.
"Where?" Your aunt began to look along the floor. All the while, your mom laughed and giggled. You couldn't believe this! Why hadnt she saved you yet? Frustrated, Betty slammed down onto a chair, crushing you underneath her massive weight.
"Come on Mary! Tell me!" She pleaded. Your mom only laughed harder. Betty was about to speak again, but then she stopped.
"Oh. I get it." She stood up. "He must have been on the chair." She turned and looked at the chair. Obviously not seeing you there, she sighed and sat back down, squashing you once more. You mentally face palmed. You had forgotten how ditzy your aunt was. Finally, calming down, your mom answered her.
"Geez Betty! He's stuck to your big butt!" Betty cocked her head to the side. Then she grinned.
"Really! Ha ha ha ha!" Betty started laughing, and your mom joined in. They laughed for a full five minutes. Eventually they finished, and Betty stood back up again. She had forgotten already, and started to saunter away.
"Betty! He's still there girl!" Your mom giggled. Betty stopped.
"Oh. Right." She reached a hand behind her to pull you off. Not being able to see or feel you, her search attempt failed. She headed back to your mom and shoved her ass into her face. "Can you get him Mary?"
"Fine." Your mom tried to slip a fingernail under you, but couldn't. You were stuck that well to Betty's yoga pants that she didn't have any leverage! Your mom frowned and tried again. No luck. She began to get impatient, and tried to rub you off, but succeeded in only grinding your face even more int Betty's big ass. To make matters worse, your mom was tickling Betty, and Hee butt jiggled as she laughed, making it nearly impossible to get you off. Finally, your mom gave up and fell back in her chair. Betty took that as a sign of success, and she sat back down too.
"Betty!" Your mom cried.
"What? What?" Betty panicked.
"I didn't have him off yet!"
"Oh!" Betty tried to stand, but several strands of her yoga pants had gotten caught on the chair. She pulled and pulled, and finally some bits of fabric ripped off her yoga pants and she could stand. By some strange coincidence, you had been freed as well, ripped clean off the yoga pants. You were left on the chair as Betty stood. Your mom saw your escape, and breathed a sigh of relief. Betty saw this, and with a confused look on her face, sat right back down ontop of you. "So you did get him Mary. Stop messing with me!" Betty giggled. Your mom put her head in her hands.
"He was free."
"Whoops." Betty laughed.
After a few minutes, you were truly free and sitting in your mom's hand. Betty sat beside her. You had explained everything, but there wasn't that much to explain. You had been sat on by a ditzy giantess. End of story.
"So Ben..." Betty began. "Sorry about that. To make up for it, you choose the next activity!"
"What?" You asked.
"We were going to either bake a cake or watch a movie next." Your mom clarified.
"You decide!" Betty smiled.
"Oh. Let's see..." What do you choose?
