She starts with just pushing a single finger passed the seal of your lips while she talks.
Her legs are straddled around your sides. You're both still wearing clothes. Nothing serious, she said. It's awkward feeling the fabrics press and slide against each other. Where her clothes touch your skin it chafes. But mostly you just feel her weight and her warmth on top of you. Comforting.
She's talking about magic the gathering of all things. Going on about her plans for the next weekend. Ideas for cool new combinations of cards, neat clips she saw on youtube, and people she can't wait to play with. It's vaguely humiliating how little you can follow and she knows it.
After the first finger, she presses another finger in. The two of them feel large in your mouth. Foreign intrusions. There's an impulse to bite down, and at first you press your tongue around them. Feeling the various textures. Fingernail and skin. Then, you gently suck on the fingers as you know she wants you to. You can tell she's enjoying it from how she smiles at you.
She keeps rambling while you're unable to speak. You don't catch half of what she's saying. Lacking the necessary pre-knowledge. You just hear words like 'shadow' and 'psychic' and 'bauble'. Trying to follow just leaves you with more questions that you can't ask. So you just enjoy the sound of her voice. The way she pronounces each syllable. There's a lovely flow to it.
Pulling the fingers out, she looks at the saliva dripping on them with some manner of disgust. You raise your eyebrows at her. What did she think would happen? Before you can get a word out she switches her thumb into your mouth. Pressing down on your tongue. As she does, she tries a little to wipe the other fingers off on your face before giving up.
Whenever you do try to focus and follow along with what she's saying it feels like she just speeds up talking. Like she's enjoying your incomprehension. A captured audience yet unable to parse the words. She's started saying made up words now and talking about advantages and disadvantages.
You can feel yourself losing control of your drool. The thumb keeps your mouth open and your tongue in place. You could fight it but you don't, that's not what this scene is about. The hold isn't really that strong, but your tongue can pretend to fight a little, push back in faux desperation. Enjoy the sensation of being controlled. The saliva drips uncomfortably down your chin. Suppress the urge to clean it off with a hand. Enjoy the humiliation of it.
Eventually, her ramble reaches a close. Her words slow down, and her focus shifts more directly to you. Eyes meeting yours. You hold the stare. She removes her thumb from your mouth, and waits for you to speak.
