The camera adds 10 (thousand) pounds...
Tsunoda from Aggretsuko with a massive, heavy, round monobutt! Her literal pear-shaped bottom is slightly wobbling and clad with bright pink panties.
She's taking a selfie with her phone, posing and winking at the camera as her massive monorump looms over the rest of her body~

(After seeing all of those drawings of her one random day, I just HAD to draw her, SHE'S SO CUTE)

if you go out to eat with me dont expect a quiet evening
a friend's sona sits at a dinner table, precariously positioned on a host of chin rolls and dressed properly for a nice evening. the table sits at the maw of an absurdly fat dragon, his thunderous belch nearly blowing his dinner date out of his chair. his face fat completely obscures all but his mouth
