After a moment of thought, a look appears on Victoria's face that could easily be accompanied by a "ding" and a light bulb above her head.
"I know..." she coos in a suggestive tone that makes you incredibly uneasy. "Gimme just a sec." She smiles a large, terrifying grin at you, slowly moving you closer to her mouth, and as soon as you begin protesting, she trivially shoves you back into the humid, foul-smelling darkness and pins you to the inside of her cheek. After a few minutes being trapped there and feeling the saliva pool up around you, she begins swishing you around, which to you approximates being in a huge, organic washing machine. You have no idea what she's up to, and this terrifies you. You can barely breathe, and your body feels like it's getting a thrashing for sure. After a minute, the fierce movement stops, and the darkness is pierced by a small bit of light coming from a little opening in her lips. The saliva begins running out, and unsure of what to do, you stay put, and feel yourself being slowly pulled towards the opening. You are drooled out, slowly descending on a large strand of sticky saliva, until you land gently in her palm. Before you can stand up, the thumb and index finger of her other hand clamp around you, and you are held outwards, finally able to see what the point of all that was - so Victoria could have her hands free to... unbutton, unzip, and drop her pants?
Victoria grins that grin at you again. "Have fun!" she chirps, before abruptly repositioning her hand (with you in it!) down and behind her... under her gigantic rear, which would be huge at normal size, but is incalculably tremendous in your current state.
You are slowly moved closer to the gargantuan cheeks, dotted with freckles and cellulite. You snap out of your trance and begin screaming - you almost wish you could go back to not knowing what she was planning.
Finally, the moment of reckoning is here, and you reach the two mountains of flesh. You are overpowered by a sweaty smell, and ignoring your miniscule protests, you continue traveling into them, squeezing through rather easily thanks to being slick with saliva. Everything goes dark and the heat is almost as bad as inside her mouth. You're actually glad she gave you the spit-rinse first, otherwise, you think, you probably would get stuck and become smothered between her cheeks. This surprises you - you would have thought her soft-looking butt would be more yielding than that.
The fingers release their grasp - you won't be going anywhere now - and she shifts to simply pushing you further with one finger beneath you. The squeeze of the cheeks lightens, and after the momentary relief you realize what that means. Sure enough, almost immediately you hit a wall. It is soft, squishy, and not the best-smelling. You scream again, realizing what it is.
You try frantically to get away, but her finger continues moving at a steady rate, and soon enough you feel your head being forced into the tunnel. You hear an enormous gasp from above, and everything slightly vibrates. Still slick with saliva, plus the sweat from her butt, you slide in with little effort from Victoria. Soon, only your feel remain outside of it, and with a final, forceful plunge, you are sent far up into the tunnel.
What happens next?
