TL;DR Fatty x Fatty is superior to Skinny x Fatty, I want to have an ERP centered around a obese MaleDom forcing a skinny FemSub into becoming his BBW Bride, either through forcefeeding, or some other means.

(Scenarios)

Delivery Girl - A simple scenario of you taking in your favorite food delivery girl to make her expand with fat, & seduce her into obese sex.

Blob King - An Obese Alien whose species has to be fat to survive, has me selected from Earth to be his immobile SSBBW bride, having a tentacle shoot out from his belly button into mine, injecting his own excessive body fat & DNA into me, transforming me into an equally obese alien for him to have blobby sex with.

Incel Revenge Fantasy - You are a Fat Nerd who got rejected by me in College, & decide to get revenge on me by tricking me into eating a Donut laced with a special oil that packs a ton of fast metabolizing calories, effectively transforming me into an obese BBW Gamer Girl Nerd for you to have furiously fat flabby sex with.

Redneckification - For a trashy cheesy scenario, I am a skinny woman kidnapped by an obese wealthy Redneck for defaming the meat industry, having me gain weight by hooking up a tube with a fattening milkshake, having me grow out & becoming an obese BBW Redneck Queen, where I am married to you & we have fat nasty sex in your Trailer, making the entire trailer shake as our flabby 500 pound bodies smack together, surrounded by romantic Fried Chicken scented candles.
