Tibetan Mastiff Vore

Context: You are a human [gender], going to visit your friend Markan, owning the largest Tibetan Mastiff in the world, standing at 5'10 when sitting down. They leave you alone with him in the living room, as they've gone out to buy groceries.

Key:
y/n=your name
You are 5'3, 17 years old.
h/c=hair colour

You ring the doorbell of the massive house.
The red door opens. 'Markan! Hey bro!' You say, patting him on the shoulder.
'y/n! Good to see ya! Come in.' He replies with a smile.
You step into the house, and marvel at the size of things.
'Wow! You have a pretty big house...for one person.' You say, looking up.
'Well, it's not just me here..' He says, turning around. 'Come see the big guy!'
He leads you into a room that looks like a living room, but lacks furniture, containing only a TV, very big sofa, and a massive dog bed, containing an even larger dog, sitting there happily, drooling.
'Holy crap!' You exclaim, moving behind Markan.
'Hey, no need to worry, Brutus is harmless!'
Brutus. A fitting name. Markan walks up to the beast and pets it.
'H-how do you live with him!' You exclaim, slowly edging towards him.
'Just take some time to get to know each other!' Says Markan. He looks at his watch. 'Perfect time actually, I need to get more groceries, so, you can stay with Brutus!'
'What!' You yell
You owed him quite a lot so you agreed.
'In the cabinet there's enough food for him, so if he begins to drool a lot, make sure to feed him once, until I get back, any more and he'll go on a spree.' He says, walking out of the door.
You turn towards the dog and say, 'So, you're not gonna eat me, right?'
The dog nods.
You look into a corner, and there is a big-ish TV.
You turn it on and it's a nature documentary. You settle on the sofa, using one of the multiple blankets to cover yourself. Brutus begins to drool, like, a lot, you look over to this, and look over to the cabinet. Grudgingly, you make your way over to it, and open it.
You take out one of the boxes that says 'Pour up to here' and you pour it into a bowl, lay it next to Brutus, and sit back down. You look at the box. It's nearly finished.
Ah well who cares, its only a little bit more.
You fall asleep.
[One hour later]
You wake up on the floor, covered in drool. Your senses begin to recover, and you see the giant Tibetan Mastiff towering over you.
You attempt to crawl over to the cabinet, but you are dragged away. He drags you back with his mouth gaping wide. You look back in horror as he wraps his tongue around your leg, pulling you into his gaping maw. You try to pull away, causing him to pull you in more and more until both your legs are fully in his throat.
'Brutus! Put me down.' you say, realising your predicament. Your lower half is covered in slobber, it's very warm, and you almost begin to relax.
Until the dog takes another swallow
. You are sent further into his throat, until you are encased fully in his mouth.
Your muffled cries cannot be heard, as you are slowly pulled into the belly of the beast.
You land in the digestive fluids of the dog, and you accept your fate. The liquid tingles, but you don't seem to be getting digested, and there's also no pain.
Maybe you'll be safe here.
Maybe, just maybe Brutus wasn't going to eat you.
You begin to black out, your eyes closing.
'I'm so tired...'
[1 hr later]
You open your eyes, and are greeted with the big form of Brutus.
He let you out?
'Good boy.' you murmur, trying to stand up, but tripping in all the spit he left.
He licks your face, making you smile.
You try again to get up, succeeding this time, and you make your way to the cabinet and pull out a box.
You pour just over the limit he's meant to take, and watch as he eats it.
He looks at you. He steps closer.
He grabs your feet with his mouth and pulls you up into the air.
You enjoyed it the last time, so why not do it again?
'Go ahead Brutus!' you say, willingly sliding into his throat as he opens his impossibly wide maw and swallows you down further.
You land in the pit of his stomach, and slowly drift off to sleep, knowing that nothing harmful will happen to you in here.
