My efforts were starting to pay off in ways I hadn't expected even before he agreed to let me quit my job. I started dressing sexier and telling him about flirting with coworkers. I even sent him dresses and other items and asked him if he felt they were sexy. I asked him to buy them and then I'd wear them to work. I worked in retail so I had access to several good brands.
It was mostly just good fun but after a few months I did start to enjoy my occasional flirting with a co-worker named Marcus. He was a tall black man, probably 5 or 7 years younger than me. He had hard sexy arms and a solid chest. We had lunch together a few times and the conversations were nearly always about work, usually gossip. One particular day I had worn a loose dress that opened enough at the top to show most of my tits. I noticed his eyes darting toward them every few minutes. That time we finished lunch and as we stood up to leave from the bar table I caught a glance of his crotch in his dress pants. Not only could I tell his large, thick size, but I could also tell he was partly hard. His tight pants revealed a lot in just the 1-2 seconds of my glance. I think he noticed me turn red in the face but he said nothing. I drove home early that day and came at least three times thinking about what would have happened if we had walked to his car instead of going directly back to the office.
That same night I felt a bit guilt and let Mike have sex. I was still so turned on and my clit was so sensitive that I moaned louder than usual. Mike noticed and started pounding into me harder. I whispered into his ear that I was thinking about Marcus. He knew who Marcus was, as I had told him about our occasional lunches. Mike kept pounding and I moaned out "Marcus! Fuck me faster!" And Mike came immediately and was shaking but I was still turned on and moved my hand down and finished myself as Mike laid there in awe. We hugged close afterwards and although we didn't talk about it, I could tell it was harder than he'd orgasmed in years.
