I was raised on a farm in the Midwest. Our nearest neighbor was a mile away. There were three children in that family, Kay was a girl my age, Kathy was 2 years older and Carl was four years older. We would get together in the summer to play games, ride horses and just together to spend time I was bored one summer day so I walked down to find some company. As I neared their home I was met by Kay. She told me to follow her out to the barn because she wanted to show me something.
We entered the barn and climbed a ladder into the loft. She pointed to a blanket that was on a pile of hay. Now I wasn't the brightest bulb on the Christmas tree but I knew as soon as I looked that Carl was fucking Kathy as hard as he could.
Kay said, "what do you think of that?"
"Looks like fun to me" I replied.
"They do it all the time," she said.
"Do you do it too?" I asked.
"A few times but Carl says she's better at it because she's older. I usually end up being the look out so they don't get caught."
I looked at Carl and Kathy again and it appeared they were both having a great time.
Kay looked at me and asked, "Have ever done it?"
"Nope, never."
"When they finish would you like to do it with me?"
"I'd sure like to try," I said.
At that moment I heard Kathy say, "come in me, Carl." and it appeared Carl was more than happy to oblige.
Carl rolled off Kathy and announced he had better get to the field to help his dad before he came looking for him. He pulled up his pants and disappeared down the ladder.
Kay laid down beside her sister and pulled up her dress. I was a little surprised to see she wasn't wearing panties. She beckoned to me and I stepped closer as I dropped my pants around my ankles. I wasn't sure exactly what I was doing so I laid between her spread legs and poked about in a feeble attempt to imitate what I had just seen Carl doing.
Kathy rolled on her side and said "Raise up." As I did she reached between us and grabbed my dick. She pushed it up and down Kay's wet slit and then told me to push. As My dick slid in, Kathy pulled her hand out of the way. "How's that feel?" she asked her sister.
Kay smiled and said it felt great. "I think he's as big as Carl."
"Maybe bigger," Kathy giggled.
I'd love to say I fucked her for an hour but actually I was finished in about six strokes. It was probably the best feeling in my life up to that moment but it was over all too soon.
Kathy laughed and said, "Don't worry about it. Carl shot his wad before he was even in me the first time. Besides, you'll be hard again in a few minutes."
I was between the girls and they took turns playing with my soft cock and it wasn't very long until I was hard again.
Kathy said, "It looks like you're ready to fuck her again."
I rolled between Kay's legs and slipped into her pussy quite easily. I lasted a lot longer this time and Kay seemed pleased with my beginner efforts.
After we finished we rested a while. Kathy asked how I liked doing it and I told her it was the best thing that ever happened to me. She gave my dick a squeeze and told me that either she or Kay would be available whenever I wanted some pussy. Kay reminded Kathy that since Kathy had Carl that she would keep me busy without Kathy's help.
Kay did a very good job of keeping that promise and we fucked almost every day for the rest of the summer. I did fuck Kathy a few times and Carl would fuck Kay but mostly it was Kay and I while Carl did it with Kathy. It's claimed that practice makes perfect and we did get pretty good at making each other cum by the end of summer. I hated to see winter come because it was usually too cold to walk that far and way too cold to fuck in the barn loft.
One cold November day just after a heavy early snow our parents had left my sister and I at home to go into town. My sister was two years older, the same age as Kathy. I was watching TV and Beth came in and sat down on the opposite end of the couch. We sat in silence for a while and then she said "I'll bet you really miss your play time down the road now that it's so cold."
I glanced at her. "Yeah, I guess. It's kinda boring when you can't go out."
She smiled, "You'd freeze your ass off in that barn this time of year and you can't do it in the house with their mom always there."
I blushed and tried to play dumb. "Do what?"
"I know what you do down there," she said. "The girls have told me all about it."
I didn't know what to say. I wondered how much she really knew.
"I go down there too. Ever think about that?"
