"C'mon Tina, Belcher's aren't quitters!" Louise barked.
"But Louise, it hurts so much!" Tina whined, "the butt is a beautiful thing, but it's also strictly a one way exit! Things aren't meant to go inside them!"
"You should have thought about that before you got yourself wedged down here. Now c'mon, we're getting you out of here before mom can investigate why her burnt bacon is getting cold."
Louise ignored Tina's further pleas. She put her free hand down on Tina's cheek and gripped it hard. Her fingers sunk deep into the flesh of her pale ass, causing it to redden immediately. Once she had a good grip on her ass, she pulled it aside, spreading Tina's cheeks as far as they could go. Her pussy, still a deep pink color and glistening with wetness, parted too, giving Louise a good view of her big sisters pussy. But her focus was on the task at hand.
"Alright Tina, this is it," Louise said, "we're going in deep and we're going in hard." She rolled her tongue around in her mouth, then spat. It landed square on the top hemicircle of her butthole, right above where her thumb was wedged inside it. The warm spit was going to make this next part easier.
Tina made a gulping sound.
Louise clenched her teeth and pressed with all her might. The resistance of an unwanting ass hole was greater than she imagined. But Louise was tough and she was determined. The bit of lube helped as she thrust forward, pressing her thumb deep into Tina's ass, ignoring the older girls hyperventilation's as she did. Her tenacity was rewarded when she saw that below here, where Tina's ass was spread out before her, her thumb was nowhere in view. It was buried as deep as it could go.
"Tina, we did it!" Louise exclaimed, "I have you in a good grip now!"
"Ha ha ha," Tina said, the short gasping sound she always made when nervous the only sound escaping her lips, "good. Ha ha ha. Job, ha ha ha. Now please, ha ha ha. Get me out!"
Louise felt the tightness of Tina's ass clamping around the base of her thumb, but she noticed how much space was in the chamber beyond it. Unlike her pussy, Tina's ass had a lot more room inside, without any tight walls to press upon her digit.
"The door is small but the room is large," she said.
"What?" Tina asked.
"Nothing."
