A trip to the beach

A weekend at the beach with some new friends what could go wrong?

Hi, my name is Steve When I was 19, I drove around in an old VW van. It had two front seats and a gap between them where you could move into the rear of the van without getting out of the van.
One weekend I took my girlfriend Tammy, my sister Pam and her boyfriend Ralph to the beach down the coast to get away from the crowds. We also rented a beach house.
We were getting close to the beach when Pam started undressing in the back of the van. I saw flashes of boob in the mirror and as I drove I moved the mirror up and down. At one point she was completely naked. Then she put the G-string on and then the top of her bikini. Ralph was watching her from the seat next to her several times he undone the string she had just tied up. Then Ralph undressed Pam decided to get revenge on him and right in the middle she got hold of his dick and sucked him off in the back of the van.
With my van in the back, I had two rows of the three seats each. I had taken out the middle row so there was a big space in the back. Pam was on her knees in that space sucking Ralph's cock.
Tammy watched the whole thing.
After they had finished Ralph and Tammy swapped places and Tammy undressed and put on her bikini. Ralph also watched her get changed. After she had finished, she told Pam she had some cum on her face and I watched as Tammy licked it off of my sister's face.
I let Ralph drive the van. Pam got in the passenger seat, and I got in the back with Tammy and changed my clothes.
I looked at Tammy hoping she would get the message. She smiled and whispered to me "I love it when it you look desperate". She got down and sucked me off. While my sister Pam looked on.
We got to the beach and did a bit of swimming. There was nobody around we had the beach to ourselves. Tammy and I went for a walk to see what had washed up on the beach. We were not gone very long. But when we returned Ralph was on my sister fucking her on the beach.
We stood there and watched them go for it.
After they had finished Pam wrapped a towel around her middle and carried her G-sting back to the car.
We drove to the house. They had a box with a combination lock with the keys in it.
We entered the hose and picked the bedrooms we wanted. As soon as the car was unloaded and the front door was closed Pam lost the towel and top. She started walking around naked. Ralph dropped his shorts and did the same. Tammy's bikini soon came off as did my shorts. Tammy picked up the towel from where Pam had dropped, we both saw a large patch of cum on the towel. Tammy dipped two fingers in it and then licked her fingers and said, "Oh yummy I can taste your sister in this." She then brought it up to her mouth and licked it.
From time-to-time Ralph and Pam would just start hugging and kissing. I was waiting for them to start fucking at any moment. I got behind Tammy cupped her breasts and kissed her on the cheek. She could feel my cock against her bum. She leaned forward reached under herself took hold of my cock and guided me to her pussy. I started fucking her from behind. Ralph and Pam had been watching and were soon doing the same thing. I loved the way each time Ralph rammed his cock into my sister Pam's boobs swung back and forth.
I knew my sister had a nice set of tits. But seeing them at this angle bouncing around. For some reason I almost said a dad joke about being careful they don't take an eye out.
I shot my load thinking about my sister imagining fucking her. Then Ralph lost his load in her. A little later we had dinner then sat around and watched TV for a couple hours.
Then Tammy started stoking my cock. I looked over and realized Pam was stroking Ralph's cock. Then both Pam and Tammy started sucking our cocks. Once we were both hard the girls led us to the bedrooms. Tammy and I started fucking on the bed and we could hear Pam moaning in the other room as they started to fuck. I had watched those two fuck twice early that day and made a lot less noise both times.
The next day we got up showered had breakfast and then headed for the beach. Several more couples had arrived and were spread out on the sand. Most of them were naked and not long after we arrive one couple started to fuck not far away from us.
Not to be outdone Ralph and Pam stripped off and started fucking. Tammy quickly followed suit and then got me out of my shorts, and we were soon fucking on the beach.
We found ourselves invited for lunch at a cabin the other couples were renting. There were four couples in their twenties they had gone to school together and do those. They brought out some alcohol and soon we had a few drinks. We were all naked wandering around this house with these people. Then I saw Pam and Tammy with their arms around each other kissing Then they were on the floor going down on each other in a 69.
Several people were standing around watching them. I went in to get a better view just as a woman dropped to her knees and started to suck the cock of the guy next to me. She then took hold of my cock and swapped back and forth sucking his cock and my cock.
The guy next to me introduced himself as Brian and the woman sucking our cocks as his cousin Toni.
I told him my name Steve then I pointed out Ralph and my girlfriend Tammy and my sister Pam. Your sister wow.
He smiled and winked at Toni.
As the evening went on, I saw more people suddenly having sex all over the house. I saw Ralph fucking Jill, Tammy fucking Phil and Tammy fucking Mike. They kept giving me drinks. I woke up the next morning I could feel a pussy on my cock; a pair of breasts pressed against my chest. A woman had fallen asleep on top of me. I opened my eyes and saw the top of her head just below my chin.
I lifted her head up and realized it was my sister Pam on me. Suddenly it all came back to me. We were both drunk. A woman sucked my cock until I was semi hard. Then two guys got Pam on me and the woman held my cock while they got Pam on to it. They then moved her up and down on my cock until I shot my load in her.
