I was raised on a farm. I was an EXTREMELY shy and a typical horny teenage boy. We had all the typical farm animals, horses, mules, cattle, dogs. you can see where this is going, At around 13-14 I discovered the animals felt better around my cock than my hand. If someone besides me was home I'd go riding to find a stump or log. We used the mules and horses in harness as well as riding them I'd take them to get firewood in the winter with a wagon, again finding something to stand on. If no one was home besides me I'd just use a hay bale, bucket anything handy to stand on. I'd let calves and puppies(before they got teeth) suck me off. I'm not huge (6.75" long and barely fit in a toilet paper roll) but we had one Shetland mare that seemed to enjoy me, when she saw me she nearly always walked over and backed up to me. She was one of the few I didn't have to stand on anything to have sex with her. Them and Nieces(in my family category) were my only sexual experiences till I got married at 25. I divorced my wife in 2008, had gotten engaged in 2010 to a girl I had a crush on in school( but was too shy then to say anything) While we were talking about sexual fantasies she admitted she wanted to try K9.i went on to tell her my experiences. We had some of the sex of our relationship the next few nights. We're no longer together so would love to find someone that's into that and family sex.
