Here's another script, highlighting my (un)healthy addiction to the beautiful sound of a female voice :) I would be the happiest guy in the world for a day or two if this one get's done.
As always, feel free to make changes and make it your own. I also hope you have lots of fun doing it.

[soft, slow .. metered .. speaking] I want your cock to explode for me, and today I'm only going to use my beautiful, sexy voice and your hand to make that happen. Thats right, I'm going to make your cock cum buckets of beautiful white cum, with only the sound of my voice. Before I start, make yourself comfortable. We don't want to make a mess of those boxers, do we? [Giggles] ... OK, good. Did you know recent studies say many women moan even after they've had an orgasm and are satisfied? When asked why, women responded that they moaned to make their partner finish more quickly. It's true! Today, we're going to have some fun with this largely unknown fact.
[The Instruction, 3 minutes]
Let's begin. Focus your attention on that beautiful, hard cock of yours. For the next few minutes, it's mine, and you're going to do exactly what I tell you. Notice how it responds when I moan.
[Moaning starts, quietly and softly] See how it starts to get hard, under the control of my voice? [more moans] Watch it! Watch as I make it harder and harder. Mmm I bet it looks so hot. [moaning more intensely] [moaning stops] Ok, now I want you to apply your favorite lube. Yea, spread it all over that ... huge ... throbbing ... cock! Your going to stroke, and your strokes are going to follow my voice. When I'm quiet and slow, you stroke quiet and slow, for example [Moaning quiet], and as I get more intense, your going to stroke faster and faster. Got it? Good.

[Edge #1, 3 minutes]
Now start stroking, and I'll tell you when you can cum.
[quiet moans start, with these words in between] Doesn't that feel good. ... Mmmm, how exiting is this? [more intense moaning] My voice, controlling your cock. I'm having so much fun with this! [more intense] OK STOP! [stop moaning] TAKE YOUR hand off your cock! Wait, wait ... 

[Edge #2, 2 minutes]
Ok, let's start again. [quiet moans start] Start stroking slowly. Notice how hard you're getting. [moaning more intensely] that's the sound of my voice. [moaning more intensely] that's the sound of my voice controlling that beautiful hard cock. [moaning more intensely] will I let you cum this time? [moaning more intense, like you're almost at orgasm] NO. STOP STROKING.

[Edge #3, 3 minutes]
Wait for me.  I know your cock is throbbing.  I know it's hard, and together we'll make it even harder.  I'm ready, let's start [quiet moans start] Watch it again, watch me make it harder.  Throbbing [more intense] Making your hand move faster up and down the shaft.  My voice, my beautiful voice making you harder.  Harder ... Bigger ... [more intense] Stroking up ... [more intense] and down.  [Encouraging, lot's of yeses and uh huh's and ok's]  [more intense]  and stop.  Take your hand off.  Wait.

[Edge #4, 3 minutes, the finale]
Relax, take a deep breath in, and a deep breath out. Take your hand off your cock and just relax. It's ok, it will still be there in a minute.
Ok[quiet moaning starts] yes here we go again. Follow me. Don't get ahead of us. This is [moaning more intensely] an experience we're sharing together. Don't cum yet. Don't cum. [moaning more intensely] you can no longer control it. I'm in control. [even more intensely] Mmm, yea. yea yea yea yea [Encouraging] Oh, wow, I'm going to make you cum. [moaning most intensely, like in orgasm]

That was so much fun.  Now close your eyes and relax.
