My family went on a camping trip, whether we wanted to or not. Dad rules.
There were six of us, Mom, Dad, My three sisters and me. I was twenty, my older sisters were twenty three and twenty one. The youngest was eighteen.
We had rented a four room cabin and I slept in the living room. Both of my older sisters had married and divorced. Neither had kids, thankfully.
We had been there before and we liked the place but my younger sister and I felt like we had outgrown that. Dad tried everything including bribe us to get us to come.
Mom convinced us by saying she would be topless most of the time and my sisters could be too.
I did not say anything.
As soon as we put everything away Mom took off everything but her bikini panties. We saw Dad squeeze a tit as he walked past her.
My sisters came out wearing only their bikini bottoms and went outside to get some sun.
I had to wait for all the rooms to clear before I could change. I saw Dad walk out wearing gym shorts, a t-shirt and hat. He had his fishing rod with him. The cabin came with a boat.
Before I changed to gym shorts he was gone.
Mom was in the kitchen as I walked in to get a coke.
"Take one to your youngest sister she asked for one.
Oh, first."
She took my hand and placed it on a tit.
"You have all privileges with mine including sucking them. So do your sisters. Ask them when you can play with theirs and what the rules are for you."
I decided to see if Mom was pulling my leg and slurped a tit into my mouth. She pressed my head to her.
"That one likes a little nibble," she said.
I gave the nipple a little nip. Mom moaned and pulled me to her harder. I sat in a kitchen chair and sat her on my lap and began devouring her tits.
My cock was already at attention. Mom felt it and wiggled over it and I nipped the other nipple.
Mom sat up enough to straddle my thighs. When she sat she moved my shorts off my cock, moved her bikini to one side and sank her pussy over my dick.
We began to fuck.
I barely managed to last until she had her orgasm but I did and she was very proud of me for that.
"You have full privileges with me now. I did not expect to give them to you for a couple of days but I'm glad that is out of the way. Take your sister her coke."
"I need to change shorts and you do too."
"No, just take them off, that's what I am going to do."
We did and we joined my sisters outside with their drinks. All three were nude. My oldest sister each had my little sisters tits in their mouth. One was fingerfucking her. The one that wasn't, my oldest sister Rachel, got up and helped Mom with the drinks and snacks then embraced Mom and gave her a torrid kiss.
Then gave an identical kiss as she grabbed my cock.
She noticed it was coated with fluids and looked at Mom's pussy. Cum was oozing out of it. Rachel got on her knees and wrapped her arms around Moms ass and devoured her pussy.
Mom had an orgasm which drew my other sister's attention to us and they sat up.
I took their drinks to them but before taking them they slurped my cock in their mouths.
We sat and as we had our drinks Mom explained to my little sister Molly that they had not invited me or her because she was not eighteen and they figured I would never keep my hands off her. She explained that Dad seldom has erections but has managed to fuck both his daughters. He really hoped he would get one for Molly.
"Son, you have a lot of fucking to do this week, I suggest you hold back on as many cums as you can."
"Understood. Molly, you can get on now if you wish."
I laid back and all saw I had a decent erection. Molly scooted to me and slowly sunk me into her pussy.
