Fat experiences

I think a lot of us are guilty of chugging heavy cream to getting extremely full. I want to gain a ton of visceral weight and expand my belly a LOT. I plan to make this shake called the “Belly Buster” that’s like 8000 cal. But if anyone has anything I could make to really make the effect noticeable, I and I’m sure others would love to hear!

I do very well with heavy whipped cream and cake mix.
what does the belly booster look like?

A belly buster is a really thick drink that I’ve yet to have but I’m interested to know your thoughts on the ingredients.
It’s made up of:
1 box of cake mix
3 scoops of vanilla ice cream
2 cups of whole milk
8oz can of condensed milk
8oz can of heavy cream
1-4 scoop of Whey protein
1 tbsp olive oil
Club soda (thin it out)
Honestly I’m desperate for my girlfriend to funnel feed me a pitcher of this, sounds so nice!
