Sexy texty games

David in our office is a cute confirmed straight-boy. He's lovely, and so is his girlfriend.
Only today, he receives a random text message from an unknown number: Are you there yet?
To which he replies: Am I where yet?
I would have probably asked who it was, at this point. Not David. But the random was onto it...
Random: Sorry who is this?
David: I was going to ask the same question... You messaged me first asking if i was there yet...
A conversation ensued.
Random: Hey sorry. that was an accident. meant to send it to my girlfriend.
David: :) all good have a nice day...
Random: So... like whats your name?
By this time David has the whole office totally intrigued. He doesn't know who it is and now he is engaged in a conversation with this guy. He didn't know how to respond to this message so he didn't reply straight away, then the random messaged again saying "So do you have a girlfriend?"
David: My name is david... and yes i have a girlfriend... What's your name?
Random: Chris. I like the name David. It's a strong name. but cute...
The office staff are now rolling around on the floor laughing.
David: Haha so really, who is this? Someone I know taking the piss?
Random Chris: I'm sorry? I don't understand... my name's and you seem nice. what do you do?
David: I'm a journalist. You?
Random Chris: Oh that's really hot. i love journalists. I'm a pilot. do you like to fly?
David: I do in fact. We're debating here in the office whether you're a guy or a girl. Where do u work?
Random Chris: On a plane. It's great fun. plus all the air hostesses. sigh. you're all talking about me? that's hot... what do you look like david? i bet you're hot ;)
David: You could find out... Call me at my desk - 6**0 9**7
The genius of the last bit is, that's MY office number. I've volunteered to intrepidly discover what Random Chris has to offer. LOL.
Although Random Chris seems to have shut up all of a sudden...
I can't wait to hear how this ends!

EDIT
Okay, this yarn has just got sooo much better. David has worked out who it is. It is a (gay) friend of his girlfriend's who he gave his number to and foolishly said "no, don't give me your number, surprise me later in the week by randomly sending me a message". To a gay-boy this is something of a red-rag to a bull.
Only now David has the power and he's decided to string him along. This is the latest message from Random Chris:
Hey sorry I didn't call. Just having lunch with my girlfriend, obviously couldn't call... say just wondering if you and your girlfriend would be open to a night with me and my girlfriend. it's her birthday coming up soon... I know it's a bit forward...
Brilliant! I'll let you know how it ends!
