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?"
"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?"
"Uh, well, I uh, no, not really." I really had the gift of gab.
She stared at me a moment and then said, "They share with you, don't you think they'd share with me too?"
"Share? What do you mean?"
"Don't be so thick." She replied. "Carl has been fucking me almost as long as he has Kathy."
"Really? So I guess you really do know all about everything?"
"Sure, I've known since the first day Kay worked up the nerve to ask you to fuck her. They've told me how much you've learned and they've bragged to me about how big your dick is."
I sat quietly for a moment to absorb that she knew all this. "I guess I don't have to worry about you telling on me since you are doing the same thing.
She gave me that 'you are an idiot' look that only a sister can give.
"Ratting you out is not what I have in mind. The snow is too deep for you to walk down and get a little. It's too deep for me too. Are you following me at all?
OK, maybe I'm not the brightest bulb on the tree. I just gave her a blank stare.
"Look dummy. I know you're horny. I'm horny too. Kay and Kathy say you have a big dick and know how to use it and the folks will be in town all day. That give you any ideas?"
"Are you saying what I think you're saying?"
"If you think I'm saying I wanna fuck, then you are right. You wanna fuck me little brother?
"I'd like nothing better. When?"
"Now dummy, I've wanted to try out your cock ever since the girls told me about it."
Beth untied the belt on her robe and opened it as she lay back on the couch. She was completely nude underneath.
I stood and yanked off my sweats in record time.
"Come over here and let me see that thing", my sister giggled. She wrapped her hand around my dick and gave it a few strokes.
"Damn, you are huge. Skip the warm up and climb aboard. We can play later, I just wanna fuck right now."
She was right. I didn't need any foreplay either. Sometime during our conversation I had become hard as chrome plated steel.
I slid between her legs and slipped right into her pussy. She was tight but so wet it felt like melted butter. I eased in and then started long slow stokes.
"Oh fuck, little brother, fuck me hard. That's so good."
I sped up and began to pound her hard.
Beth began to chant a string of incoherent obscenities as she grabbed my ass to pull me in deeper.
"I'm cumming, I'm cumming, fuck me, I'm cumming".
As she shuddered and wiggled I pumped a huge load into her pussy.
After we collapsed beside each other I said, "I think that was the best fuck of my life."
She smiled and said "It sure beat any cock I've ever had. We won't have to walking to the neighbors next spring as much."
"So you might be willing to fuck me again?"
She laughed and said, "How soon can you get it up? The folks won't be home until dark."
She grabbed my dick and started to stroke it. "When we do go down to visit them, you won't mind Carl fucking me will you?"
I grinned, "It's gonna be nice that we can visit together and not have secrets."
She looked at my cock and said, "My god, the thought of the five of us fucking is making you hard again. Let's go upstairs and fuck some more."
I won't argue with that.
