Marsha, this is serious stuff so I'm going to get right to the point. First, get yourself one of those sexy French Maid outfits and serve him his favorite drink. I've never talked to a guy who didn't have a french maid fantasy so this is guarenteed to get his attention. Next, (and this is really important) make sure the underneath area of his computer desk is well padded and clear of all obstacles. Be sure to tell him you don't want to interrupt him from his important computer work and then slip under the desk, get on your knees and ... well you know what to do from here.
You won't have to be down there very long before he's in the mood, so now you're ready for the "piece de resistance". (Oh Gary, how bad is that) Push his chair back far enough to climb on his lap and then whisper the following words into his ear; "hey stud, now let's talk about the first thing that comes up" and get ready ro rock and roll.
Marsha, does this sound like a plan or what!
