In the year of everybody’s Lord, 1870, being sixteen and a cowboy in the Wyoming Territory was the tough, but glamorous life most young men dreamed of who read the dime novels about such things.
It was 1870 but, unhappily, I was sixteen and not a cowboy. The Lord didn’t seem to have much use for me, either.
I suppose I?m not being fair, because I did have a pretty good life. If I had known what was going to happen to me in the future I would have smiled a lot and been quite happy, cowboy or not.
I live with three women. My father died in a mining accident so I have been “the man of the house” since I was six. In this case, the “house” was the building that was currently being used as a dry-goods store. My mother, Emma, and my aunt Matilda run the store and my sister, Chastity, works there. I do odd jobs around town, which can be just about anything. There isn?t a surfeit of working men in town and most business owners don?t want to hire a full-time man to do little chores, so they hire me to do them and only have to pay for that job.
The dry goods store used to be something else, but it wasn?t anybody?s home, because it isn?t laid out like a home. What I mean is there is one big room on the main floor, where the store is, and one small room in the back where there is a cook stove and table to eat at, with a small larder that sticks off to one side, like it was an afterthought. We all sleep in the upstairs room, over the store. The upstairs room in the store is fairly large, being maybe thirty-five feet long and fourteen wide. The roof slants in from the sides, but that really isn?t a problem. Clothing storage and beds and such are near the “short” spaces, where nobody needs to stand up. Whether it was by design or not, my sister and I slept in the same bed until she was fourteen and I was fifteen. Our bed was at one end of the room and my mother and her sister’s beds were at the other end. My aunt was unmarried and what was called an old maid in those days. A small potbellied stove sat in the middle and extra goods were stored wherever they would fit.
This arrangement was fine until Chastity and I entered puberty. Even though she was a year younger than me, our interests were similar and our interest in sex was on an identical plane. This not to say we overtly thought about sex. We knew about it by the time I was ten and she was nine. There was a building in town that had “Hotel” painted on it in big, faded letters. It was actually the saloon, and everybody knew what the men and women who went upstairs were doing; they just didn?t talk about it. I don?t know if they ever rented a room to somebody as an actual hotel room or not.
What happened between me and Chastity wasn?t planned. It just kind of happened. We had always cuddled for warmth in the winter time and the winter I was fifteen and she was fourteen, while we cuddled we kind of moved around a lot. What I mean is, something made us want to wiggle against each other. I had been getting a stiff pecker for a long time, and Chastity knew all about that, of course, but my mother and aunt did not. So, the fact that I had a stiff pecker while we were wiggling against each other didn?t bother her. My boner had rubbed against her hundreds of times.
What my boner had not done, hundreds of times, was slide right into my sister?s pussy. She yipped and I froze. It was hot all around my dick and I honestly did not know what had happened.
“What?s wrong?” I whispered. We didn’t want to wake Mother or Aunt Mattie up, because they got cranky if they didn’t get a good night’s sleep.
“You hurt my privates,” she whispered back.
“What do you mean?” I asked,
She moved and I felt the heat climb further up my cock.
“Your private thing is up inside my privates,” she gasped, softly.
“It feels hot,” I grunted. I had the strongest urge to push, but I didn’t. I was afraid I’d hurt her. Her pussy felt like it was trying to push me back out.
“You?re making a baby in me like they do upstairs in the saloon,” she said, softly. That?s how things had been characterized to us by my mother when she had to explain why the men and women went upstairs, together. We took one meal a day in the saloon because the cook and Mom had an agreement about her trading him supplies for his kitchen in exchange for the four of us getting to eat there. Anyway, Mom said that those people were going upstairs to make a baby. That was confusing, because we knew all the girls who dressed in scanty clothes and hung around the bar until some man wanted to take her upstairs to make a baby, and none of those women ever got pregnant. Well, one or another did, now and then, and she?d go off with the cowboy she?d taken upstairs. These women tried to make a baby with all sorts of different men, so it was a puzzle as to how they knew which man they?d been successful at it with. Each girl had a favorite cowboy, though, and that?s who they usually went off with. We supposed it was to be his wife, since the only other pregnant women in town were married.
Anyway, when I finally realized what she was talking about, instinct made me thrust and my whole penis got surrounded by that amazing heat. Chastity groaned and I said, “Are you okay?” and she said, “Yes. Please don?t stop doing that.”
I didn?t know what she was talking about. We were on our sides, which wasn?t the optimal position for brand new lovers. She knew what she was talking about, though, and she rolled up on top of me. Then she started moving up and down and back and forth and it felt super good on my pecker and she made these soft gasps and something grabbed my cock and squeezed it hard and I shot off in her, just like that.
I did know about shooting stuff out of my penis. That was one of my favorite things. I had learned that it felt good to rub my pecker when we were in the horse trough out back of the store. That?s where we took baths in the summer, and Chastity and I took them together. That was late at night of course, and it was dark, so nobody could see us. Mom and Aunt Mattie took their baths there, too, also at night. In the wintertime Mamma had a big pot she heated water in on the stove and then everybody used a towel to wash all over with. Mamma and Aunt Mattie helped us until we were maybe twelve, or so, but we all stood around the stove while baths were going on.
This one time while we were taking a bath in the horse trough my pecker got stiff. I grabbed it and my hand moved on it and that felt good, so I kept moving my hand. It started feeling really good, but I was splashing a lot so I quit. Later, when I got the chance, I got out behind the stables, where nobody ever goes, and I got my peter out and rubbed it to see if it felt good like that, and it did and it got to where I felt pain, except it was a good pain and then I squirted and boy, howdy did that feel good. So, I did it whenever I could after that.
Now I had squirted up inside Chastity and that felt even better. We were both breathing hard, and it took a minute for us to catch our breath. I can’t explain it, but somehow we knew it would be better if Mama or Aunt Mattie didn’t know about this, so we tried to be as quiet as we could. I kept my peter up in her while we did that, but I could feel it getting soft.
“Did we just make a baby?” Chastity whispered.
?”I don?t know, but it sure felt good.”
“It did feel good, really good,” she said.
“What if we did make a baby?” I asked. “Is that okay?”
“I?d be fifteen before I had it, and I?ve seen girls that age with big bellies, so I guess it would be okay. I like babies.”
So, we both liked it, but we knew Mom and Aunt Mattie didn?t approve of the men and women in the saloon making babies, so we assumed they wouldn?t approve of Chastity and me making a baby, either. Neither of us thought anything about the fact we were brother and sister, but we kept it a secret because we didn’t want Mom to make us stop.
After that, I almost always went to sleep with my pecker up inside Chastity, after I squirted in her. We figured out how to make her feel that special good, too, so she was always happy when we went to sleep. She always got on top of me and sat down on my boner, until one night I rolled on top of her and said, “We should try it this way.” She let me and we found out she could get that special feeling more than once if I went long enough. It made me feel good to hear her whine and say that feeling was there and I figured out ways to move that helped her get there. One of the best ways was to go all the way in her and then just move my hips back and forth and in circles and I almost always had to kiss her to keep her from making too much noise. Then, after she said she was happy, I?d start moving in and out of her as fast as I could without making noises, until I squirted. Man, that felt good to squirt way up inside her!
We didn?t make a baby. We knew this because she had her visit where she had to wear the special cotton belt Mom made for her. Mom and Aunt Mattie had them, too. There was almost no privacy in the upstairs room, but that didn?t seem to bother anybody. I got to know a lot about women things just by being quiet and listening, and watching.
So the fact that we hadn?t made a baby made us think we couldn?t make a baby, and we kept on feeling good in bed every night. We also started doing it in the daytime, if we knew Mom and Aunt Mattie were going to be busy and not come up there.
That went on until I was seventeen, and then my whole life changed. I was on top of Chastity, getting ready to spew, when Aunt Mattie yelled, “What in the blue blazes are you doing?!” She had come up to get a bolt of cloth that was in storage and caught us, naked and making a baby.
Well, the first thing that happened was Aunt Mattie said, “You get off of her this instant, Bobby Silvers!”
So, I did, but I hadn?t spewed, yet, and my pecker was as hard as it had ever been. When I stood up, Aunt Mattie said, “Oh my Lord. That thing belongs on a horse!”
Aunt Mattie got our mother involved, naturally, and there was some awkward discussion that was had.
First, Mom wanted to know how long this had been going on, since Aunt Mattie said it was obvious Chastity wasn?t fighting me off. And when we told her, she put one hand over her eyes and said, “It?s a miracle you didn?t get her pregnant and make a baby!”
Chastity, being only fifteen and fairly short on worldly experience, said, “Well, we tried to make one as often as we could, but it just never happened.”
“You wanted to have a baby?” asked my mother. Her voice sounded different in a way that I had never heard, before. It was tense, or intense or something.
“Well, not exactly,” said Chastity. “But now that I think about it, I’d rather have a baby with Bobby, because then I won?t have to marry a cowboy to have one.”
There was some stuff going on, here, that I wasn?t privy to, but which I found out later. I’m going to tell you about it now, because it will be helpful to understand why things happened the way they happened
My mother was thirty-two years old and Aunt Mattie was two years older. When they were growing up they had an uncle named Bob. I was named after him, in fact. Uncle Bob helped work the land and he lived with them. Mattie was born in 1834, and Mom was born two years later. Around the time the girls were 14 and 16, Uncle Bob thought they needed to know what it meant to be a woman. He had been talking to them about this for a long time, and had touched Mattie since she was fourteen. He kissed them both on the mouth whenever he could get them in some private place, such as collecting eggs from the hen house, or cleaning the tack the horses used when they pulled a plow or whatnot.
