So this is a true story and not a fantasy. I was about 12 years old and was constantly horny and hard and always wanking my cock. I was walking home from school one day and I saw this horse in the field near my house. It was a very quiet area with no houses or people around. The horse walked over to the fence and I suddenly noticed his massive black veiny cock was just hanging down and twitching. I was immediately turned on and got instant rock hard cock. I was desperate to touch the horses cock. I then noticed to the side of the field were some trees and bushes - so I walked the horse to them and jumped over the fence - I was so nervous but so excited too - I reached down and started rubbing his huge black balls and I could immediately tell he was enjoying it - I then slowly held the huge thick shaft in my hand it was so big and warm - I started to wank the cock up and down and it felt amazing as it twitched and jerked - I then pulled my rock hard cock out of my shorts and started wanking myself as I wanked the huge horses cock - I then got so horny and turned on that I bent down under the horses belly and pulled the cock into my face and licked the shaft and then quickly put my mouth around the tip and sucked it for about 10 secs - it was so horny that I shot my load all over the floor - I was hoping the horse might cum too but I think it got spooked by something as his cock started going up - I often wank thinking about it now - would love to do it again.
