You've never actually seen someone peel grapes before you watched Tweek eat them for the first time. Not that Tweek had never eaten grapes before, because with the skill he's peeling those grapes with his shaking hands, he must do this often enough, but you've just never had the opportunity to watch before.
"Mn! What!?"
"Hm?" You were watching him. He noticed. How does he do that?
"You're staring at me man! What is it!?" You watch as his expression shifts to panic and his body starts to tremble in that way you can practically feel yourself. "Ah! Oh god-! There's something on my f-face isn't there?! S-someone's behind me with a bottle rocket?! Fuck!"
"No." You quickly assure him. And assured he is; his tremor calms and he heaves such a relieved sigh, it makes your own heart race. Yeah, that's it. That's always been it: Tweek's near-complete submission to you, to your judgment. Sometimes you wonder how easy it would be to just take him for yourself. You're almost certain he's gay and would probably consider you to be attractive. His baby-animal eyes and pouty lips make you think it'd be an easy task but sometimes you get the sense that there's more to the blonde than that. Something a little darker, maybe a bit dangerous hiding just beneath his jittery surface. "Just- why are you peeling those?"
"Fucking pesticides, man! I don't want to die!" He practically scoffs, as if you even had to ask.
"Oh."
