I really dont have any actual scenarios on mind but some concepts I love a lot is the idea of ordering a huge take out and greeting a cute fat delivery girl being all obese and slobby.

Lethargic and waddling to the door as my loud heavy steps shake the whole house. Only to greet them with my huge pale tummy plopping outside the doorframe before me. Letting out some sweat and fumes...

Inviting the poor soul to come over to feed me, leaving them no choice as I loom them over with my lard. Having burger after pizzaroll shoved into my maw. Feeling their own weight over my growing body, looking at their sweaty uniform being squeezed with each effort as they keep feeding me...just growing HUNGRIER

Once its all clear and devoured, ending up with my last entry and slurping them whole. Head first into my throat as her fat ass wobbles outside of my mouth....SSSHHLLURRP

Feeling the poor girl move and struggle next to my past meals, barely making any indent due to how huge I got from this single binge session. Pressing my gut against a surface to shut them over, forcing out some gas from both ends. Belching out a pair of digested panties...hehe

Something like that I like for me ><
