Hard to choose. I’d say this one or any of my old Cammy buttjobs ones.

It’s my favorite because what drove me to learn to animate in SFM in the first place was how desperate I was for a buttjob pic with Cammy. It’s why if you look at my oldest animations, their all animations of her just rubbing her butt on a cock in various ways.

Funny story, back when SFM wasn’t a thing yet and I only had GMOD, I would spawn the Cammy model and a dick, pose them both and use the Phys Gun to manually make it look like Cammy was giving a buttjob. I wish I could post them now along with a whole bunch of screenshots but they were all lost in a reformat years ago.
