My day to remember

I was 15 at the time and still a virgin, although more and more often I was playing with myself thinking about sex with girls.
I was lucky my cock was much bigger than all my friends, it was 7” long and nice and thick and as I was on my way home from school I would never have believed what happened!
I took a shortcut through the neighbour’s farm and as I passed the stables I heard some strange sounds so I decided to sneak a look. Quietly I crept behind the large doors and I peeked through the gap and I could hardly believe my eyes….
Beth, who was Farmer Joes wife, was lying down on some hay bales totally naked and she had her hand wrapped around a horse’s massive rock hard cock.
She had a beautiful body for her age which I guessed was about 35, she had large breasts and a slim waist and I could see her other hand playing with her pussy which was completely shaved. I watched her as she slowly wanked off the massive cock which was about 14” long and unbelievably she also started licking all around the huge head, and as I watched my own cock quickly grew harder than ever before.
I undid my jeans and took it out and I started playing with myself as I watched her and after she had licked all over the head I heard her moan with lust before taking it into her mouth.
But to my horror after a few minutes I heard her say “ why don’t you come and join me so you can see much better honey” … I froze unable to move at first, but then just as I was about to run away she said “ its ok I really would like you to come beside me and watch me Please”
I put my cock away and did as I was asked and nervously moved into the barn shuffling over next to her… she smiled and said “well let’s start off by seeing what’s making that nice Big lump in your pants” and she leaned over and very quickly undid my jeans and pulled them down releasing my aching cock.
My cock was really hard and she put her hand around it and told me I was lucky to have such a big one at my age and then she slowly ran her tongue up and down the shaft and all around the base of the head.
