Loving this thread! I flirt with the straights at work often. There's a couple of them on my team that I call 'dad' even though they're the same age as me and they love it - they actually started it!
I worked with a guy a few years ago but he resigned and moved away. He's a typical straight guy, decent looking, but does not have much luck with women. Only once he resigned did he tell me how he really felt when we worked together...he said he was curious the whole time and wanted to be sucked off.
He snapchats me now whenever he's drinking asks what i'm up to, and the next day when he's hungover he'll snapchat pics of his cock. Naturally I do the same, and as a result we've had many 'virtual' wanks together via snapchat.
