Poop and anal play

I can remember my first time experiencing someone else’s poop. I was 17 or 18 and gong down on my girlfriend and finally got up enough nerve to try putting my finger in her ass. There was a pump bottle of hand lotion next to her bed (she used it for hand jobs for me) so I took a squirt for my index finger and pushed my finger up her rectum. I did get it all the way in, but I was rushing and clumsy and got the dreaded “Ouch! That hurts!” and that was the end of that. It was dark so I couldn’t see, but when I went to the bathroom to piss a short while later, I looked at my finger and saw her brown poop in the crevices around the sides of my finger nail. I was not the least bit turned off. In fact I was mesmerized by it in two ways. It was somewhat like a souvenir of having been up her butt where I had dreamed of going for a year. It also was a bit exciting as it was a private aspect of her. Knowing that she would be so embarrassed that I was looking at her poop on my finger was thrilling and very hot for me to contemplate. If there was more of it (maybe enough to produce an odor) I don’t think I would have liked it at all, but it would not have deterred me. I washed it off with soap and water, but the experience was seared into my memory.
