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.
