Sister joins in (Part 1)

Reading "caught by mom" first might help with this story. Please note what that story is completely fictional!

The day had begun with me masturbating to porn on the computer and had progressed further than I thought could ever happen. After a quick break from my mom fucking my brains out, she asked me what I wanted to do now. I told her that I wanted to cum in her ass again, but I wanted to do it on the back porch. She hesitated but then agreed. We went outside and she got on all fours and stuck her beautiful ass in the air. Before I did anything else I looked aound to see if anyone was watching. If the neighbors on eitherside decided to go outside, they could see everything since our porch did not have any walls. The thought of that is why I wanted to go outside.

After a quick look around I slowly slid mu dick into my mom's ass which made her moan. I started to slide my dick in and out of her ass. Even after the beating I gave her ass earlier, it was still tight in her. Ten min. of slowly fucking her ass, I looked up and over at the neighbor's house where the girl was earlier in the day. What I saw made me explode right away in my mom's ass. I had no time to warn mymom and she was shocked by what she felt in her ass. She told me that she had never felt (or heard of) that much cum entering another person from one other person, after the amount of sex we had so far. She asked me how I did it. I told her to look at the neighbors yard. My mom looked up and had two orgasms from what she saw.

The girl was in her backyard naked fingering herself. There was another girl there who was also nude. The neighbor was eating her out. Thats what made me cum. My mom came when she noticed who the othe girl was. It was my 24 year old sister.

When my mom came she let a out a loud moan and that got my sisters attention. She looked over and saw her mother and brother looking at her having sex with another girl. Me and mom were shocked at what had just unfolded. we went back inside and I sat down to think about what I should do next. My cock as still hard even though I had sent the biggest load I have ever had into my mom's ass. My mom was still horny so she walked over to me and started sucking mu cock. It felt better than the other blowjobs I have recieved. I was about to explode when my sister walked inside through te back door. She was still nude and stuck her pussy in my face. I started to lick her cunt (like mom she dosent shave either) which taste like heaven.

When mom saw my sister, mom told us to repostion ourselves on the floor. I layed down first. Mom then started to suck my cock again. My sister then put hersel in a postion where I was eating her cunt and she was eating mom's cunt. After about five minutes I could take no more and warned them that I was about to cum. Mom stopped sucking and told my sister to suck my cock. My sister eagerly went to my cock a sucked it. She deepthroated it like she was a professional. I almoste cacme in her mouth, but she knew right when to stop sucking. Right as I pulled out of her mouth I blew my load all over face. Mom then started to lick my cum off of my sister's pretty face.

My cock stayed erect as my mom layed down and my sister starting eating her out again. I knew what My sister wanted as she stuck her ass in the air. I slid my dick her her virgin ass. There was a lot of resistence and she was moaning in pain as I slid it in. Mom told her it was well worth the starting pain. Eventually the moans of pain turned to pleasuew moans. For what seemed liked hours I fucked my sister's ass as she ate my mom's hairy cunt. I then exploded a massive load in her ass and slid off. We all then layed there for a few min.

Mom made dinner and we all talked about what we should from now on. We all had the day off tomorrow and theats when my sister suggested getting hte neighbor girl involved. That idea was what I was wating for.
