Yo man. I can help you. I have some experience in this situation. I know it's a long post, please take the time to read it through. I'm sure it will help you
The thing you want to do is very delicate and difficult. The thing is, phone sex has some sort of weird and perverse name, you know. If you don't play it right, the girl will freak out and your chances might be blown with her.
I have done it before, but the girl I did it with, was my fuckbuddy for maybe a year or so. So I knew she was very comfortable with me and wasn't shy about her body or 'sexual desires'. What I'm trying to say is, I don't know whether my method works with a girl whom you don't have this kind of contact with...
So what you do is actually very simple. What you say is not very important, it's THE WAY YOU SAY IT. When you want a phone call to transfer from a 'normal' conversation to a sexual conversation, you need to make the girl feel that the SPAM is changing... You can lower your voice, talk slower, pause more,... But don't do it suddenly. BUILD IT UP.
So what do you have to say? You need to choose a context or a setting you want to make the conversation happen. For example, the girl I had phone sex with, is a teacher trainee, just as I am. I started telling her that it would be great to be a teacher in the same school later. I started fantasizing with her I fantasized about a situation where we were working late together at school, everyone left except for us... This is a setting thathas a sexual SPAM around it already. SO you really need to think of a good setting and how you lead the conversation to that setting is up to you.
You have to escalate the situation. Say things like... "In my fantasy, I see you working in your classroom, and your back is faced to me. I enter the room slowly and silently, and catch you off guard with a soft and gentle hug..." You see? You don't say anything sexual, but the conversational heat is turned up A LOT.
Notice that I use a lot of adverbs and adjectives: soft, gentle, slowly, silently,... choose your words right. This is a very important aspect!
Probably, she will say something like: "Hmm... go on..." and you just continue. You say that your hands are around her stomach, and ask her if she likes that. Say you blow in her neck, kiss her ear or something. Ask if she likes that... Tell her your hands slide down really slow... And continue this, you get the point, don't you?
When you reach a point where your story is getting really sexual, you say: "I'm quite horny right now, how about you?"
And your phone sex is on! Say things you want to do to her, ask what she likes, what she wants, what she wants to do to you...
Now, something you might not have thought about, is closing the conversation. You have to stay in your roll. I always say something like: "I have a class early tomorrow and need to leave. Hope I see you again soon..."
If you don't do this, the closing can be a really awkward moment...
So to sum up:
1. Choose a setting and lead the conversation to there.
2. Adjust your word choice, voice etc to a more 'sexual' use. Build this up!
3. Escalate the story.
4. Listen to her. Is she moaning? Ask her if she is horny like you.
5. Keep escalating! Make it as dirty as you want.
6. Involve her in the conversation. What does she like? What does she want? Does she like what you say? What does she wants to do to you?
7. Enjoy, don't be tensed.
8. Think about the closure.
So dude, think about the conversation beforehand. Setting, closure etc. Be confident, don't make it obvious that you're nervous. It might be silly, but it can help if you practice that voice/story in advance.
I hope this helps man. Just go for it and let me know how it worked out!
