"Open up," Katsuki’s voice comes forth, raspy and heated, and it's clear in his tone that it’s not a suggestion. So, you obey the simple command before it even fully registers in your mind, plush lips falling open, tongue peeking out over your bottom teeth.
Katsuki grins meanly at your compliance, sliding two of his thick, sugar-coated fingers into your awaiting mouth, and pressing them down over your tongue until they hit the very back of your throat.
You gag, unable to help your reflexes, but you dare to pull back. Instead, you close your lips around Katsuki’s fingers just as he likes, sucking weakly, long eyelashes fluttering against the apples of your cheeks, tongue dragging over the pads like it’s instinct. Because at this point, it is.
“That’s it,” Katsuki mutters lowly, his deep red eyes fixed on your throat, like a predator watching its prey, waiting for the opening to strike. His free hand strokes slowly up and down your bare spine, soothing in contrast to the weight of fingers in your mouth. “You know what I want, Don’cha? Get ‘em nice and wet, pretty girl.”
You moan softly around his fingers at the words he spills, nodding, beautiful eyes glassy and dim. Even like this, you still look at Katsuki as if he put the stars in the sky with his own two hands. Spit gathers in the corners of your pretty plush lips, glistening down your chin as you bob his head faintly, tongue working up and down, weaving in between those two digits with desperation.
Just as you’d do to his cock, if that’s what he’d shoved in your mouth instead.
“Filthy. You’re such a filthy girl.” Katsuki breathes, almost amazed. And you nod your head, knowing that you are. That the both of you are. After another minute of just admiring his pretty girl, Katsuki pulls his fingers free, strings of spit clinging between them. Delicious. He taps your cheek roughly with wet hands, just enough to get your attention, and your eyes flutter open.
“Eyes on me, girl.” He says, tongue licking along his canines. “You don’t get to look away, understand? I want you to look at me while I fuck you, want you to scream out for me. You hold back, you close your eyes, and i’ll fucking spank you til you cry.”
Your eyes water, and a shiver runs down your spine. You know he means it, and God, you almost want to disobey just to be punished. Another day, perhaps. Instead, you lean forward without ever breaking eye contact. “Yes, sir. I’ll be good, promise.”
He reaches back with that same spit-slicked hand and takes a fistful of your hair, yanking you closer to him and reveling in your hiss of pain. "That’s my good girl.”
