Okay.  This happened Tuesday of this week. 
I work in a small office, only 4 of us including me, and this week everyone is out for one reason or another, except me.  When my boss is out, his son (call him D) will sometimes come by the office to do some things for his dad like ship some packages or cut the grass. 

I've know D since he was 5 and that was 12 years ago.  So now he's a senior.  He's a good looking guy, about 5'10, and over the last year he's put on some muscle (arms, chest, abs, legs), probably due to
his girlfriend.  They're a cute couple and as far as I know, they're sexually active. 
Well, like I said, I'm the only one in the office this week and it's getting close to quitting time when I hear the main door to our suite open.  No one said anything so I get up to see who came in and it was D.  He was doing some things in his dad's office.  I said hello and made chit-chat for a few minutes, then returned to my office.

A few minutes later, D comes to my door, leans on the door frame and starts with some small talk about school and such.  A few references to sports and how soccer was going.  It was then I noticed his hand was down around his crotch area and he was moving his thumb along what appeared to be the outline of his dick. Just to carry the conversation further to see if the outline would get an more
pronounced, I asked how his girlfriend was and how things were going. He said they were good, but would be a lot better if she'd put out.
Even though I was hoping for such a reply, it kinda stunned me for a moment at the abruptness.  I said, "Well to be honest, I don't know what to say to that. You are a senior and I'm sure there are guys your age that are doing things and just as many that aren't.  So don't let it bother you.  You're a good
looking guy and I'm sure the time will come when it's right."
He looked me right in the eye and said, "Yeah, maybe, but I'm tired of just jacking off.  What am I gonna have to have to do to get this dick sucked?" With that, he grabbed his dick, which was definitely hard and clearly defined in his shorts.  And of course I looked right at it.
Holy fuck.  Did he just say what I thought he said?  So now what?  I've never been one to be at a loss for words and can usually come back with some kind of witty comment to something like that, but not this time.  I just kept staring at him slowly stroking his dick through his shorts.
Still stroking his dick through his shorts, he said, "You're gay, right?"  I said, "You know I am.  You've known that for years."  He goes, "You wanna suck my dick?"  With that, I think the blood drained out of me. Lightheaded, heart bout to beat outta my chest, palms breaking out in a sweat I said, "D, why would you ask me something like that?  Have I ever given you that impression?"  He said, "No. Never. But you're here by yourself and I'm horny and I thought I'd just throw it out there to see what you'd say." 

I said, "Is this some kind of test? Are you messing with me? You do know your dad is my boss and I'd hate to lose my job over some kind game."  D said, "No test, not messing around, no game and no worries. So let me ask again, do you want to suck this dick?"  With that, he pulled his shorts down in front so that his hard dick was now just free and standing at attention. 
I looked at his dick, then up at him.  He had this devilish grin, then parted his lips, slipped his tongue out ran it over his lips and said, “Well?”

I looked back down at his dick once more then back up at him and said, "Go lock the suite door."

(Will post Part 2 soon as I can.)
