It was a Saturday afternoon at our house. Bree, mom, dad and I had been involved sexually for a while now. Bree was over for the day and we were all hanging around the pool. Dad was bartending and we girls were tanning nude on floats. Bree and I were questioning mom about her having already fucked Mike, our stepbrother. Mike was a personal trainer at the time and in great shape. Both Bree and I wanted our turn with him. I was turning seventeen and Bree was eighteen. It only seemed right. It would give dad some help dealing with all the pussy and give us another big cock to share. Win-win.
Dad just laughed, saying when all three of us were home he could use the help. But, he added, he could handle two of us alone. Dad called Mike and told him we were hanging around by the pool and that we were going to cook out later. He agreed to come over and join us. We girls devised a plan to catch him off guard. Bree and dad put their suits back on and mom and I went to her bedroom to put on lingerie.
Mike showed up a little while later and headed out to the pool. Mom and dad’s bedroom is just off the pool area so we could hear him.
“Where’s Kat and Ada?”
Bree responded, “I think they’re in mom’s room. Why don’t you let them know you’re here.”
Mike went back into the house to mom’s bedroom. He knocked on the door and mom told him to come in. Mom and I were on the bed, on our knees, in lingerie. He stepped in, staring at our two inviting asses in the air. I couldn’t wait.
“You like what you see?”
“Yes, I do. Is this what I think it is?”
“Yes, it is, son. It’s time the girls join what you, me, and your dad have been enjoying.”
With that, Mike dropped his shorts to the floor, exposing his big cock. He climbed on the bed behind us and pulled off both our thongs. He started licking my pussy while he rubbed mom’s ass. Then he switched, tongue fucking her. He continued switching back and forth as we both moaned in pleasure. After a few minutes, he got behind me and rubbed the head of his cock up and down my wet slit. He unclasped both of our bras, letting our big tits swing free. I felt his cock slowly start to enter me. I heard mom gasp and looked over my shoulder to see he had shoved two fingers deep into her pussy. Then he pushed all the way into me. I moaned, letting him know I wanted him.
He fucked me slowly at first, then began pounding my pussy good. He continued finger-fucking mom as she pushed back against his hand. Mom and I started kissing as my brother continued fucking us both. He pulled his cock out and positioned himself behind mom. She was so wet he shoved his cock all the way in. I got up and rested my head on her ass, watching him fuck her. He pulled his cock out and shoved it in my mouth. I could taste our pussies on his cock. He then shoved it back into her.
Mom was slamming back against his every thrust. Back into my mouth, I gagged trying to swallow the whole thing. Back into her, his balls slapped her clit.
I rolled over onto my back and spread my legs wide. My shaved pussy was glistening with the wetness. He took the hint and pulled out of mom. He grabbed my hips and pulled me closer to him. He placed his cock at my entrance and shoved it in. I let out a scream as his balls hit my ass. Mom came over and started sucking my nipples while my brother fucked me like a slut. He continued pounding me until he felt my pussy contracting.
“Cum for me, you little slut.”
My legs started shaking as I started to cum. He didn’t slow down until I completely erupted and pushed him off. Mom took his cock deep in her throat. He was fucking her throat until he started coming. She was gasping and gagging as she took his entire load.
We all recovered after a few moments and decided to head outside.
“Did dad know about this when he called me over?”
“He sure did,” I responded.
As we walked out to the pool deck, we found dad on the daybed with Bree straddling him. Her hands were on his ankles as she rode his big cock. It was amazing to watch her take him so deep in her tight pussy. She was moaning loudly.
Mom, Mike and I got into the pool and watched dad fuck Bree. Mom and I leaned against the edge of the pool with our heads on our arms. Our legs, floating behind us, were spread open. Mike stood between us rubbing our pussies at the same time. Bree finally started coming. She quickened her pace, slamming down on his cock. She stopped, her legs quivering, and her moans turned to screams. She finally rolled off totally satisfied.
“I see things have changed some,” Mike said.
Bree smiled. “I want you next.”
Dad explained to Mike he had been fucking all three of us for a few months. He further explained that, since Mike had been fucking mom, it was only right he fuck the daughters, too. Mike agreed and was happy to fuck all three of us.
“Let’s show the girls how we team up, dad.”
With that, Mike escorted mom to the daybed where dad was still lying. Dad’s cock was still hard when mom straddled him. She placed it at her entrance and slid down the large shaft. She was facing him and leaned forward so dad could suck her nipples. Mike was masturbating his cock back to full erection, as mom rode dad’s cock. Mike straddled dad’s legs and lubed mom’s ass with his saliva. He placed his cock at her little rosebud asshole and slowly pushed it in. Bree and I watched as mom took both big cocks at once. Being so full of cock, It didn’t take long before she was coming. She pushed back on both cocks until she leaned forward, shaking in an uncomfortable orgasm. When mom recovered they got up.
Bree immediately got on her knees at the edge of the daybed. Mike knew what she wanted and got behind her. He placed his cock at her tight pussy entrance and pushed in balls deep. She let out a moan and started rocking back on his cock. I lay on the daybed with my legs spread wide, waiting for daddy to fuck me. Daddy knew what I wanted and buried his cock deep inside me. Bree and I were moaning in pleasure while the two big cocks fucked us.
Bree leaned over to suck my big tits, while Mike fucked her hard. Daddy was pounding my pussy with all he had left and we came together. My legs were shaking as daddy pulled his cock out and shot his load on my tits and Bree’s face. Mike kept pounding Bree until she climaxed. He pulled his cock out and shot his load on her back.
Bree was licking daddy’s cum off me and mom licked up Mike’s load. After a few minutes, we all got in the pool. We were all talking about how great it was that we could now share each other. Before the day was over, Mike fucked us each individually – and so did dad.
From then, Mike stopped by when I got home from school for some one-on-one. He also stopped by more often since he didn’t have to sneak around to fuck mom.
Once I’d graduated from high school, Bree and I were allowed to join the swing group. This just extended our family group to more women and several more cocks. You may not agree with our family dynamics, but it works for us.
