You gotta convince me she says
She's down bro, you need to show sexual value and possibly sext a bit and it's a done deal.
"Do you enjoy multiple oral orgasms?"
-->She could say yes duh-->Then ask her how many she usually has in a session-->She'll say either 0 or 1-3 like almost girls-->Then you show value and tell her you usually give your girl 5-10 (or 10-15 if you are feeling confident)-->Then switch the frame to you and her "Since you're new to this, I'll start you off with 5 and see how your body handles it"-->Should be done by this point, you can add a sext if you want.
If she says no she's never had one, "Shit I'm sorry to hear that"-->she'll respond and you'll say "Most guys don't know what they're doing or just don't like eating pussy. I love it"--->Then link back to above script.
Other option is to just send her a dick pic lol
What if I don't want to go down on her? I'm kinda paranoid about getting herpes or some shit but I do enjoy doing that in a relationship or with a girl that I've been seeing multiple times.. any other good way to sext her you think?
Use the same line i gave for the 4 hrs away girl just tweak it a bit and u can add something sexual like oral skills etc
