Not being concerned about being naked led to incest

Mom and Dad were not shy about nudity and sexuality. It rubbed off on my twin sister and me.

I grew up with loving parents. Dad had a really good job and made pretty big money. Mom did not work except to do Mom things. We lived in a custom built three bedroom house on five wooded acres with a pool, in an upscale suburban neighborhood. Life was good.

I had a twin sister. Her name was Tina, but I always called her Sis. In the early years we shared a bedroom, but never a bed. Our third bedroom was used as Dad’s home office. We were not nudists, but it was no big deal for any of us to go around the house naked for one reason or another. Unless we had company, we also swam in the pool naked. Dad said that it felt so much better. I remember a couple times seeing neighborhood kids peeking out from behind trees as we were in and around the pool. Mom and Dad hugged and kissed and touched a lot, even when they were naked, but we never saw them having sex, although some nights they were pretty noisy in their bedroom. I saw Dad with a hard-on a couple of times. His weenie, that was what I called it back when I was little, was huge compared to mine. I wondered if mine would get that big someday. Of course Mom and Sis did not have weenies. They were girls.

Time passed and Sis and I both grew. I now called it my dick. My dick was growing and I started getting pubic hair. Sis was getting the start of having boobs. She used to say. “Someday I’m going to have boobies bigger than Mom’s. We would laugh, because Mom had pretty big ones.

One day out by the pool, I was right next to Mom, talking to her and my dick got hard and touched her. That was when Dad’s office became my room and Sis and I no longer shared a room. Mom had a talk with Sis and Dad had a talk with me about the birds and bees.

Just after Sis and I turned fourteen, Mom and Dad had another talk with us. We were all together this time. This was back before the internet. The talk was not just how babies were made, but about the process of getting the girl pregnant and making the baby and how to not make a baby if you didn’t want to do things except just for fun. They also mentioned that people who were not married to each other or in love would sometimes have sex just because it felt good and they wanted to. We were old enough to know much of what they were talking about already but they told us some new details. Dad told us that brothers and sisters and even first cousins were not supposed to have sex together. Then in a strange tone of voice, he said that if they did, they had to be sure that no one else knew about it. He also said that a child having sex with a parent was one of the biggest no-nos and how other people would think they were really bad, if they found out. They told us that if we ever had any questions, we could talk to either of them about anything and they would not get mad. He knew that we were old enough to be thinking about each other that way. So far Sis and I had not done anything more than look, but we were sure thinking about our bodies differently than we had been. Actually, there was one time a couple of weeks ago when we did spend a couple of minutes touching each other’s parts. I really got hard when she held my penis.

About a month later, Sis and I were in the living room and Mom and Dad went to their bedroom. Soon we could hear them having sex. We looked at each other and giggled. I was going to my room but as I walked down the hall, I saw that Mom and Dad’s door was wide open and they were on the bed fucking. My cock instantly got hard. I went back to the living room and told Sis, “Come on, you have to see this.” She followed me.

Mom and Dad were not looking our way as we stood in the doorway watching them. When Dad groaned and obviously came in her. We hurried to our rooms before we got caught looking. The next day when we were all together, Mom said, “We knew that you two were watching us. We left the door open on purpose. We thought that would be your final lesson about sex. Did you like what you saw?” We both blushed but said yes.

That night at about eleven, my bedroom door opened and Sis walked it. She was naked and so was I. She walked over to my bed and sat on the edge. She took my cock in her hand. It quickly hardened. “Do you want to fuck me?”

“I want to so much. I jerk off thinking about doing it. When I shoot my cum, I’m imagining that it is squirting in you.”

“Well then, let’s do it. Have you ever fucked a girl?”

“No. Have you let a boy fuck you? I know that it is supposed to hurt and be bloody the first time. I don’t want to hurt you, but I dream about fucking you and sucking on your titties. I also don’t want to take a chance on getting you pregnant. I don’t have a condom.”

“I popped my own cherry with a carrot about a week ago. It did hurt and I did bleed. Mom taught me about the menstrual cycle. I can’t get pregnant right now. This is the perfect time. Let’s do it.” Tina got on my bed. “Get on top and put it in.”

She spread her legs wide and I got between them. I held my cock and found her opening. I had to push hard but I got it in. “It hurts a little but it feels good, too. Start moving in and out.” It felt great to me.”I started fucking her just like I had watched Dad doing to Mom. I was finally fucking a girl, not just my hand. I only lasted about thirty seconds when I could not hold off any more. I shot my stuff in my sister’s pussy. I pulled out and told her how good it felt. She calmly said, “Yeah, it felt good but it sure didn’t last very long.”

We kept doing it. Every couple of days or so we would find a time and place to fuck. I found out about oral sex and Tina tried sucking my cock, but she did not like it so we only did it that one time. I found a dirty magazine and it showed different positions. We tried many of them and we both liked doggy best. I started lasting a lot longer and that made Tina enjoy it more. It was really exciting when I gave her her first orgasm.

I also found two other girls who let me fuck them. Then one day I found myself out by the pool between Mom’s legs, sliding my cock in and out of her. It was exciting but I liked sex with Tina better. Her cunt was much tighter. Mom told Dad and that night we watched Dad fuck Tina for the first time. She went wild. Maybe it was because Dad was still bigger than me, or that he rubbed her button while he fucked her. I remembered that so I could do it next time.

From then on, till we graduated from high school, the four of us shared each other’s bodies and fucked any time we felt like it. Sometimes all four of us would enjoy sex together. Dad and I would do Mom in the cunt and ass at the same time. Tina always said no to anal. She never even tried it once. Mom loved eating Tina’s cunt when it was full of cum with either my or Dad’s or both of our cum loads. She also loved sucking my cock. Tina never did learn to enjoy oral sex with me or Dad but she would occasionally do it because she knew that we really liked it.

Tina and I were accepted to the same college and we accepted. We got an off campus apartment together. No one knew that we were brother and sister. They just knew that we shared a one bedroom apartment. We still dated and fucked other people but loved each other. It continued like that till we graduated.

We both got jobs but continued living together like man and wife. We both also had friends with benefits and even joined a swingers club. Together we had a son and a daughter but they were not twins. The boy was a year older.

Years later, after Mom and Dad had both passed away; we were sorting thru their things and found paperwork that told us that Mom and Dad were brother and sister.
