Awkward Erection

 Several years ago, my wife and I had a mutual friend named "Kristy". We used to hang out together with her and her husband. She would stop by every once in a while and smoke, have some coffee. Just casual friends for the most part. She and I flirted from time to time and talked dirty to one another off handedly. Just playful bullshit between friends. My wife would get into it as well.  One day Kristy stopped by to drop off something for my wife. So the wife hangs out for a few minutes and then she leaves for work while we nurse coffee and smoke a joint. While we're smoking we got into the subject of penises. Laughing about how they look floppy and pathetic when their flaccid. Then she says "I love see to dicks when they get hard" which just flipped a switch. I was wearing my standard at home clothing. Sweat pants, t-shirt and no underwear. All of the sudden my cock just wakes up and starts swelling. We had talked like this before. She is a very attractive women, I might say and she looked great that day. I think she noticed me squirming around with a growing appendage at work. She gets up and a says she's going to smoke a cigarette outside at her truck and to follow her out to see her off while the erection seemed to abate.   We go downstairs to her SUV. She lights up sitting in the driver's seat. We keep talking and again my cock starts to stir and then it just popped up hard as a stone. I was at an age (and I still am) when erections don't just "pop up" often. At this point, I'm not sure how to react so I just look away and continue talking while trying to make my cock calm down. The more I tried to become unaroused, the harder my dick seemed to get by the second. So there I am standing in front of Kristy with a fat erection trying to be nonchalant. I finally turn to her thinking she's probably staring away from the awkwardness of the situation. But I turn around and she is quite obviously staring at my cock. She never took her eyes off of it while we talked. Even when she said goodbye with a smile she was staring directly at it. On one hand, I was so turned on I just wanted to drop my sweats and just stroke myself into ecstatic orgasm. On the other hand, I was afraid she was going to freak out somehow about my getting an erection. Her reaction was surprisingly pleasant. She didn't say anything about it, but she just stared intently which made my cock seem to throb even more and the tension build.  So she takes off back to her office and I immediately went into the downstairs bathroom to relieve my aching cock. I could feel the heat and the swollen veins on my dick. I stroked my penis in earnest. I just stood in the middle of the bathroom with sweats around my ankles stroking and stroking until my cocked gushed. There was so much cum I heard it splatter on the floor. I still get hard thinking about the situation. The look in her eyes while she stared at my dick has stayed in my mind for years. I always hoped it turned her on somehow and she thinks of me when she masturbates, but who knows?! We haven't seen her in a long time, but I will never forget her.
