I need to talk dirty in a text to my girlfriend give me and explicit text about how I'll make her bite her lip and grab the bedsheets and cum on my face

Here's a suggestion for a flirtatious and steamy text for your girlfriend: "I can't stop thinking about how you’ll bite your lip and grip the bedsheets when I take my time with you. Just imagining the way you’ll react makes me want to be there right now, losing myself in you until we both can't hold back anymore. I want to feel every intensity build until I can taste your pleasure on my lips. Just think about it, babe." Feel free to adjust it to match your style and comfort level!
