Thank you all for your supportive comments. I went to the farm this morning as planned. I was shaking so bad getting out of the car. I can't believe my husband let me go never mind driving me there. The owner met me in the driveway and met my husband. We talked for a while and discussed limits and such. My husband stayed in the car when the owner led me to the barn. His wife was in in the barn already I talked with her alone for awhile, which calmed me down so much. I then followed both of them to a stall where the horse was. It was not as big as I was expecting, definitely taller than me but still a normal looking horse I guess. They both walked me through the process, and his wife then started working on the horses cock. She had already started before I got there. His wife had me kneel next to her while he stood in front of the horse, holding it stready. She guided my hand to it and the moment my skin made contact I thought I was going to pass out from the anxiety. She guided my hand up and down the length, slowly and gently. The horse made some noise and moved a little but was mostly very calm. She then put her hand over mine and had me grip the shaft and actually start stroking it. It felt incredibly sensual but also incredibly wrong. The sensual side eventually won out as she guided my other hand to this cock that was about the size of my forearm and his flare was a little smaller than my fist. I stroked it clumsily for a couple of minutes, adjusting to the strange feel and not really able to get into any rhythm. I then decided that was enough for the day and excused myself to stand up. I thought about doing more but decided to savor the win in overcoming a huge fear. His wife asked if I wanted to see her finish it and I did. She took over and mostly used her hands, but also her mouth a little, and it could not have been more than a couple of minutes when she made the horse cum and it was a lot more than I expected, She asked me if I wanted to smell or maybe taste it, but I declined and told her maybe another time. The three of us talked about the experience as she cleaned herself up a little, and they walked me back out to the driveway. They said I did a lot better than most first-timers. I am not sure how true that is but I want to believe it. We talked a little about next steps and the possibility of me visiting again. I said I would talk to my husband first and let them know. Typical "thanks" and "goodbyes" and we left. My husband is amazingly supportive, but doesn't want to see me doing it in person at this moment. I will probably be going again based on how I feel at this time.
