Unfortunately, you were wrong. Toriel grabbed your ankle, and pulled it up into the air. You were left dangling in the air, held up only by her large hand. You tried to reach up and pry open her grip, but she was too strong for you. She lifted you up to her hungry grin. She brought your face close to her maw, and licked your face. You squirmed as you felt her saliva slather you, and tried to push yourself away from her.
"Mmm, tastier than a snail," Toriel said, licking her lips. She lifted you overhead, and opened her maw wide. Before you could even scream, she let go of you, letting you fall towards her awaiting mouth. Her lips snapped around you, stopping just at your waist, dangling inches away from her throat. She used that moment to lick you all over a little more, the sounds of her content "mmm"s radiating all around you. You were crying. Of all the people that'd want to eat you, why'd it have to be Toriel?
She parted her lips, and let you fall towards her throat. In little time, you felt the entirety of your body get squeezed by her monstrous throat as it pulled you, in tandem with gravity, down into her awaiting stomach. You cried even more as you approached the sweet monster's insides. The narrow tube you squeezed down quickly opened up into her stomach, and you fell in with a plop.
"Ahhh," Toriel sighed. She patted her stomach contently, shaking you up in the process. "So, so tasty," she commented. You, meanwhile, pounded against her stomach walls, begging to be released.
