Brother / sister incest became an incest threesome and then a foursome.
I felt my orgasm building. My balls tightened and my dick swelled and stiffened even harder. I pushed her legs even higher up by her chest till she was almost doubled over and slammed my cock fast and deep into my sister’s asshole. She was moaning. My cum exploded from my nuts and shot down the length of my shaft and started to fill her butt. After the first two ropes, I quickly pulled out. My mother’s face was right there, and her mouth quickly engulfed my cum covered and still erupting six-inch shaft till my cockhead entered her throat. Two more shots of my cum filled her mouth. She quickly swallowed.
I rolled away and Mom put her face between Tina’s legs and started eating her pussy, paying a lot of attention to her clit. It wasn’t long before Tina was thrashing around and having a great orgasm of her own. There was some of my cum still dripping out of Tina’s asshole. Mom licked it up as Tina started to come down from her orgasm. As I watched Mom eating Tina, I got hard again. Mom was the only one who had not come yet. I was going to fix that. I rolled her on her back and got between her legs. I easily slid into her wet pussy. It was nowhere near as tight as Tina’s ass, but it still felt great. Because I had come just a few minutes before, I lasted for a much longer time. Mom started a series of orgasms. Each one was harder than the one before it. Finally, she screamed and shook and collapsed. Almost simultaneously, I had another orgasm and filled my mother’s cunt with my seed. We lay next to each other and cuddled.

It started a couple months earlier when Mom came home from work a little early and caught me with my dick pumping in and out of my sister’s pussy. At first, she exploded in anger. She pulled us apart and sent me to my room. I noticed her looking at my still hard cock as I left the room. For the rest of the day, Mom was pissed and showed her anger.
My name is Ralph. I’m seventeen. I’m on our school football team, so I have built up a pretty nice body. My sister is Tina. She just turned fourteen. Mom is Joyce. She is thirty-eight. My father’s name is Sam, but he is out of the picture. He left two years ago. I overheard them fighting about Mom having a friend at work, a friend with benefits. I looked up the term on the internet and learned that it was that they were fucking. Mom said that she belonged to several clubs and went to meetings a couple times a week. Dad watched us but did not pay much attention. After Dad left, I was old enough to watch Tina while Mom went out. She started staying out later. Mom and Tina are both petite with small but nicely shaped tits, but they are both attractive.
The night that Mom caught us, after supper, she spoke with a softer tone in her voice. She called us into the living room, “We need to have a family talk.” Months ago, Mom had put Tina on the pill, ‘in case she got raped’, but had a talk with her about not having casual sex. “I know how young people get very interested in sex and that there is a lot of peer pressure to do it. You know that incest is not accepted in our society. I’ll tell you a secret, my first sex was with my brother when I was Tina’s age. The pill or condoms are not foolproof but there is a way to have sex and be sure that the girl can’t get pregnant. A girl has two other holes that a girl can use. I don’t expect that I can stop you if you are determined to have sex together but think about what I said and be careful. Be very careful not to let anyone else find out.” We looked at Mom and then each other and smiled.
The next day when Mom got home, Tina and I were on my bed fucking up a storm. I was still fucking her pussy without a rubber and pulling out just before I came. We didn’t stop when she stood in my doorway, and she did not stop us. I soon noticed that she had her hand between her legs and was rubbing herself as she watched. “Mom, don’t just stand there. Take your clothes off and join us.” I could not believe how fast she stripped. “I’m almost there. I’ll pull out and you can suck my cock while I come.” Mom jumped onto the bed and put her face right next to my cock and Tina’s pussy. I pumped a few more times and then I yanked my cock out and shoved it in Mom’s mouth just as it exploded. I filled my mother’s mouth with my seed and she swallowed every drop. She did not stop blowing me till my dick wilted. Tina watched. If Mom would have kept sucking my soft dick, it would have quickly hardened again, but she didn’t. Then she shifted her position and started eating Tina’s pussy. We had not expected that. Tina had her strongest orgasm ever.
It wasn’t long after that, and we were having regular threesomes. Mom insisted that Tina take me in her mouth or up her ass, But I could fuck Mom’s cunt and come in it. She said that she had her tubes tied after Tina was born. Mom and Tina started really enjoying going 69 with each other. I loved to watch them, especially if I had just blasted a cum load in Mom cunt or Tina’s ass. Tina got a boyfriend. He was my age. She told me, but not Mom, that she was letting him fuck her pussy and come in her without a condom. She thought that the pill would protect her and she loved the warm wet feeling of cum in her cunt. She said that if Mom was not home, I could use her pussy and come in her, too. She loved sucking me clean after I came in her. She would not suck my cock after I had fucked her in the ass. I guess that I don’t blame her. She told me that she had sucked off one of her teachers to keep from getting a D in his class and that she was thinking about doing bad on the next test so she could suck his cock again.
Then one morning when we got up and went to the kitchen for breakfast, there was a guy sitting at the kitchen table in just his under shorts. She introduced him as Devon. Mom said that she liked this guy enough that he was going to move in with us. She also said that she had told him all about the sexual relationship that the three of us had and that our threesomes would now become foursomes. He insisted that he should be allowed to cream Tina’s pussy and he was not about to take no for an answer. We started to have hot foursomes with both of us creaming both Mom’s and Tina’s pussies
After a couple of weeks, Mom took me aside and told me that Devon wanted to fuck my ass and have me suck his cock as part of our group sex. She said that she wanted me to do it. Right now, I am trying to decide if I will allow him to do that, or if I should pack some things and move out.
