My little sister

I grew up on a farm with only my parents, my little sister, and of course many animals. My mom home schooled us, so we really didn’t get to see much beyond the farm. It got lonely, when I wasn’t tending the animals or doing chores, but since I had turned thirteen, I had books and my right hand for masturbating. It began when I watched the animals mating for the first time. My cock got hard and slippery and felt like it needed a release, so I started jerking off as the animals were fucking.

I was cleaning the stalls one day when the horses got a little excited and the stallion mounted the mare with his two-foot-long cock and began humping. I stopped cleaning and dropped my jeans to pump my cock, but was startled by my little sister running into the stall all bug eyed and shocked. It was a little awkward with my jeans around my ankles and my cock in my hand. She saw the horses but gasped when she finally looked at me, and saw what I was doing.

I quickly pulled up my jeans and muscled my erect cock away from sight, but she couldn’t stop staring at me.

“What were you doing with your thing out?”

“Look sis, it was a private thing that guys do when they get horny, and you shouldn’t have seen that”.

“What does horny mean?”

“You are too young to understand”.

“So, explain it to me.
