Original Post:

Two lovers call each other at an agreed-upon time to masturbate together on cam. They're both horny and ready when the call starts but what was planned as a simple mutual masturbation session turns into hot webcam sex with a dildo.

Provided are two voices: Robin and Ben. Robin can have a pussy or a cock. The alternative phrases for when he has a cock are included in (brackets). If you're recording this as a single voice script-fill instead of a collab with both voices, best pick Robin. His/Her voice is written to stand on its own and give the listener all the necessary information.

Some [stage directions] are added in brackets but I didn't go overboard with them. Just act out what's happening.
That's cool, Baby. You know how it is, suckin' and moanin' and whatnot.

[Robin]     There you are, right on time. Oh nice, got your cock in your hand already!
[Ben]        Yeah, been touching myself for a couple minutes.
[Robin]     Yeah, me too. The anticipation made my pussy all pink (my cock all stiff). Look!
[Ben]        Mmh, that's fucking hot.
[Robin]     I'm glad. Your cock looks pretty heavy already! Mmh.

[Robin]     Scheduled sex is great. No awkward segues. Just your cock in my face right away. You call and we're both already horny...

[Robin]     God, I love looking at your cock like this. Still malleable. I wish I could have it in my mouth.
[Ben]        You want it in your mouth?
[Robin]     Ha, only pretty much always. But yeah, now especially.
[Ben]        Open up then!
[Robin]     Just open my mouth?
[Ben]        Yeah! Open up! And stick your tongue out too!
[Robin]     Ok! [open your mouth, say a breathy "Ahh"]
[Ben]        Fuck, that's hot.
[Robin]     [talk with open mouth] Yeah?
[Ben]        Yeah, I'm imagining pressing my cock into your soft tongue...
[Robin]     [open mouth moan]
[Ben]        ... and sliding it into you. Mmph.
[Robin]     Yeah, slide it over my tongue!
[Ben]        Hush, keep your mouth open!
[Robin]     Ok, ok! [open mouth "Ahh" again]

[Robin]     I got a better idea, actually.
[Ben]        What? Come on, you're so hot!
[Robin]     Trust me, you'll love this. Let me just.. grab my dildo.. [rummage in your nightstand] Mmh!!
[Ben]        [understanding what Robin is going for and loving the idea] Oh, alright!

[Robin]     Mmh. Do you like seeing me like this? With your cock in my mouth?
[Ben]        Yeah.
[Robin]     Sucking on the head..
[Ben]        Mmh.
[Robin]     Dragging kisses across your shaft..
[Ben]        Mmh, you love it, don't you?
[Robin]     So much!
[Ben]        Put it in your mouth!
[Robin]     In my mouth, already?
[Ben]        Yeah, I wanna feel your wet mouth stroke me.
[Robin]     Ok. [suck it] Like this?
[Ben]        Bob onto it!
[Robin]     [slowly fuck your mouth with the dildo but not deeply] Like this?
[Ben]        Deeper.

[Robin]     How about you show me?
[Ben]        Hm?
[Robin]     How you want to use my mouth.
Spit in your hand. Get your fingers wet, like my mouth.
And then stroke your beautiful cock as fast or as slow and as deep or as shallow as you want to be in my mouth..
[Ben]        I like that. [spit, spread it on your cock]
[Robin]     Mmh. Yeah, make a loose ring with your wet fingers! Aaand stroke it, yeah, like that. Mmmh. [fuck your mouth with the dildo, slowly at first and not deep]
[Ben]        Fuck, you're hot.

[Ben]        So you're going to do everything I show you?
[Robin]     M-hm! Anything you show me.
[Ben]        I want to go a little faster.
[Robin]     [fuck your mouth faster]
[Ben]        You turn me on so much. Keep taking it.

[Robin]     Your cock's getting wetter!
[Ben]        More slippery too.
[Robin]     That's more than the spit. The spit should be getting less as it gets rubbed in. You're getting wetter!
[Ben]        Less talking, more sucking.
[Robin]     [refocus your efforts on sucking the dildo]
[Ben]        Mmh. But yeah, it's getting wetter.

[Robin]     I wish I could taste you.
[Ben]        Yeah. I love your face when you taste the first gush of precum.
[Robin]     Mmh, there's little I love more than how your cock tastes.

[Ben]        Oh yeah, what else is there? What DO you love more?
[Robin]     You got me there! Really, the only thing I love more is when you fuck me!
[Ben]        Is that so?
[Robin]     Yeah.

[Ben]        Do you have lube?
[Robin]     Yeah, I got lube, but I don't like the taste of it.
[Ben]        It's not for sucking.
[Robin]     [gulp] You wanna-..?
[Ben]        Fuck you, yeah. In your ass! Get the lube!
[Robin]     My ass?? (My ass? Right now?)
[Ben]        Yeah. You make the cutest whimpers when I stick it in your ass.
[Robin]     Oh, you wanna make me whimper, huh?
[Ben]        Yeah. Get the lube.

[Robin]     Ok! Liking where this night is going. [rummage for lube]
I was really just expecting us to masturbate together. Here we go!
[squirt some on the dildo and stroke it onto it]
[Ben]        Mmh, I like the sound of that.
[Robin]     Sloppy, eh?
[Ben]        Yeah. Kindles great memories too.

[Robin]     Alright! So, same deal as when you fucked my mouth, ok?
[Ben]        I guide you, you translate my hand-movements to fucking?
[Robin]     Yeah. The dildo is going to be your rock-hard dick.
And your hand is going to be my tight ass.
Make it really tight! I want a super tight grip!
[Ben]        Yeah, I'll make it as tight as your ass. Look! It's gonna almost hurt to squeeze my cock in there.
[Robin]     That's how it's gotta be.

[Robin]     Ok, but stop if you notice I'm hurting-...
[Ben]        Of course!! I got you. Don't worry. I got you.
So, bring the dildo to bear..
[Robin]     Ok, I'm pushing it against my hole. Now it's all up to you.

[Ben]        Alright, watch closely. Juuust the tip.. of the tip.
[Robin]     [slooowly push a little bit of dildo in] Mmh!
[Ben]        And back out. Just gonna go back and forth with juuust the head.
[Robin]     [very shallow fucking]

[Robin]     Oh my FUCK, is it ever hot, to see your fat cockhead squeeze itself into that tight ring.
How it deforms.. and throbs when it's almost through.

[Robin]     Ah, ah!!! There it goes! You pushed the head in!
[Ben]        Did you too?
[Robin]     Yeah, I pushed it in too. I got your head in me now.
Fuck, I like how it expanded right as it made it through your fingers.
Think it would do that in me t-... Ah, ahhhhh, you keep pushing!
[Ben]        Hell yeah, you can take it, right?
[Robin]     Yeah, it's ok. Once the head is in, it's all good.

[Ben]        Goood. Juuust take it!
[Robin]     Mmh, feeling your girth travel into me...

[Robin]     I wish I could feel your flared cockhead, spread my guts for your cock as you push in.
Trail blazer. But I would still feel so fucking stretched by your shaft. Mmh!
[Ben]        No way around that. God, you're tight.

[Robin]     Look, it's all in! Taking my hand off the dildo a second so you can see...
[Ben]        You don't know how much this turns me on.
[Robin]     Yeah, well, I love seeing your cock like this too.

[Robin]     With your tight grip all the way at the bottom of its shaft. Proudly surging up. Swinging a little, moved by your pulse..

[Robin]     And to imagine that's all inside me now... Mmh!
[Ben]        You got another three seconds to admire it.
Then I'm gonna have to start fucking you.
[Robin]     MMmmh!!
[Ben]        I can't see your ass presented like this and NOT want to fuck you.
[Robin]     Fuck me then, if you can't take it anymore!

[Robin]     Mmmh, yeah, slowly pull out of me... but keep your head in, please!
[Ben]        Mh-hm, that head's not going anywhere. Look at my tiny strokes!
[Robin]     [quick, shallow thrusts] Oh, oh, oh, oh yeah, fuck me, fuck me with just.. right behind your head.
You love those quick, little strokes, huh?
[Ben]        Yeah, your tight asshole rubbing my frenulum...
I could cum just like this.
[Robin]     Fuck, that's hot.
[Ben]        But I don't want to.

[Robin]     [he thrusts into you hard] Fuck!! That was sudden!
[Ben]        I like that you did it.
[Robin]     Well, of course! Anything you show me on your cock, I'll do!
That was a hard thrust though.
[Ben]        Yeah, I wanted to see if you'd do it.
[Robin]     Uh-huh.
[Ben]        And I wanted to see you wince from my cock.
[Robin]     Fuck. Well, you got it.
I like those long. slow. deep. thrusts we got going now.

[Robin]     If you go just a little faster, you're gonna make me cum.
[Ben]        Mmh, good!
[Robin]     [go a little faster]
[Ben]        Rub your clit a little faster too, hm? (Stroke your cock a little faster too, hm?)
[Robin]     Yeah. [do as instructed]
[Ben]        You like being fucked in the ass, huh?
[Robin]     I love being fucked in the ass!
[Ben]        Are you gonna cum on my cock?
[Robin]     Yeah. Soon too!
[Ben]        Mmh!
[Robin]     I feel it building in my ass. Oh god!
[Ben]        Don't rush it, let it build!
Let me fuck it into you!
[Robin]     Oh yeah, fuck it into me! It's spreading!
[Ben]        Yeah, your cunt (cock-head) is beet red and swollen!
You are so fucking ready!
[Robin]     It's surging up my pussy (balls), right into my c-.. oh fuck, OH FUCK! [orgasm]
[Ben]        Fuck yeah, cum around my cock, I'm burying it deep!
Mmh, yeah, slam your legs shut, you're only making yourself tighter for me..
Mmmhh, I like seeing you shudder.

[Ben]        Beautiful. Let me pull out and jerk off for you, hm?
Don't have to follow my hand anymore.
God, you're lovely-...

[Robin]     Shh! No. Don't pull out! I want to keep the dildo in.
[Ben]        I'm horny enough to burst though, I NEED to jerk off!

[Robin]     Just keep fucking me. It's ok.
[Ben]        But you just came!?
[Robin]     I know, but I want you to keep using me.
Until you cum too.
[Ben]        You gotta be sensitive as fuck.
[Robin]     Yeah! But grip your cock tight for me..
Show me! Yeah, real tight.
And keep fucking me!
Keep fucking your doll!
[Ben]        Fuck!
[Robin]     Your cum-drunk fuck doll.
[Ben]        Fuuuck.
[Robin]     Yeah, you like that? Fuck, it's so hot that you keep going. Fucking your tight hand-hole.
[Ben]        And you, fucking your little asshole!

[Ben]        I like seeing that dildo disappear in you.
[Robin]     M-hmm.
[Ben]        Over and over.
[Robin]     Mmh!
[Ben]        Your hole stretching around it..
[Robin]     Yeah!
[Ben]        Gripping it when you pull out..

[Ben]        Your pussy is so wet it's running over. (Your just keeps pulsing out wetness. Damn!)
[Robin]     Yeah, I'm leaky wet mess. I feel it on my thighs.
[Ben]        I like it.
[Robin]     Me too.

[Robin]     That does it for you, huh? You're going faster!
[Ben]        Yeah, I'm getting close, I think.
[Robin]     Like fucking me when I'm (hard and) leaking like this?
[Ben]        Freshly fucked, still dripping..
[Robin]     Such a usable fuckdoll.
[Ben]        Fuuck!
[Robin]     Haha, you're so easy.

[Ben]        [speed up, faux aggressive] Wipe that smirk off your face!
[Robin]     [fuck yourself really fast] Oh fuck, you're going fast now!!
[Ben]        Yeah!
[Robin]     Are you there, where you can't hold back anymore?
[Ben]        Mh-hm.. Gotta fuck. Take it!
[Robin]     Fuck, I love when you're there. Just have to fuck, and fuck, hard and fast!

[Robin]     Look at the dildo, I'm going as fast as you're stroking! Fuck!! Oh god..

[Robin]     Fuck me as fast as you need! I can take it. Use me! Just fuck into me!
[Ben]        I wanna cum so badly!
[Robin]     I know, I can tell. Your cock is so fucking red and swollen! Go on, cum in me! I want your cum. I wanna feel it.
[Ben]        I'm so FUCKING close!
[Robin]     I want ropes of cum hitting my insides.
[Ben]        Fuck, fuck, fuck!
[Robin]     Fuck me like a fucking rabbit!
But when you cum..
[Ben]        Mh?
[Robin]     Shove your cock as deep as you can into my guts! And then shoot your ropes of cum even deeper!
[Ben]        [you're THIS close to cumming, frustrated as all hell]
[Robin]     Oh fuck, oh fuck! Yeah, let loose for me!
Ow!! OW FUCK! YEAH, SHOVE IT DEEP!
[Ben]        [orgasm]
[Robin]     OH FUCK, YEAH, CUM FOR ME! Fuck, look at you spurt! I got the dildo in to the fucking hilt, looking at your cock explode, I can almost feel you twitching in me!

[Ben]        [still coming down] But NOW I gotta pull out.
[Robin]     Ha, yeah, now you get to pull out.
[Ben]        Turn a little so I can see.
[Robin]     Like this? Can you see ok?
[Ben]        Yeah.
[Robin]     [pull out the dildo] Mmhhh.
[Ben]        Your hole is all puffy.
[Robin]     Yeah.
[Ben]        It's lovely.
It's showing me I fucked it. I love that.
[Robin]     My "puffy asshole", eh? Such a romantic.
[Ben]        I calls it like I sees it.

[Both]       [slowly calming down]

[Robin]     I love you.
[Ben]        I love you too.

[Robin]     Call you back after a shower? Gotta wash the dildo too.
[Ben]        Yeah. Sounds good.
[Robin]     Alright, see you in a bit!

Retrospective:

I've had this idea in my head for a while. Wanted to record it as an audio but something always kept getting in the way. So now I wrote it down as a script. As I was writing it, I figured since I'm imagining it anyway - I tend to imagine what my imaginary lovers could be saying - I might as well add the second voice too.

Formatting this took me ages. First I had it typed out with one voice in normal type face and one voice in italics. Pastebin doesn't show italics, however. So I went with names. First it was JS and CC, for Joe Schmoe and Cursive Curtis. Felt a bit silly though and JS and CC are both two letters. I wanted a different number of letters to differentiate them better at a glance. So I went with Ben, because my girlfriend likes that name, and Hugh, as in "You, the performer". When I was done though, I noticed it would be easy to convert this into a version where the speaker is a woman, so I added that option and gave Hugh a unisex name instead: Robin.

Worked some things in there I know my girlfriend likes. Like the "open your mouth" part and some phrases like "ropes of cum", haha. She recently heard that in an audio and it tickled her.
