Cousins side of the family

This happened back about 38 years ago. We had been to the beach and we were all covered in sand. So as we went in the back door aunt said everyone strip and go rince off in the shower. So all the older people went first then us younger people were in line some of us looked mighty fine,I didn't know that almost everyone was clean shaven below. It got down to her her daughter and son and a older uncle and me her kids are around 13 or so. Her uncle is jacking off and he came fast. Then he was limp. Her kids said that he cums small loads. I laughed at them. Then we went in the shower and she said since we're last might as well use soap. And she said you wash her and I will wash him and I said then I will wash her down. She said I'm looking forward to that. Her daughter had soaped her face upper body and her legs then she said wash my fun parts. So I soaped her all over her back and her butt and then she turned around and put my hand on her chest and she slowly moving my hands to her below the belt parts. I soaped her with my hand and she was moaning and said to mom his hands are very nice mom then her brother said my turn and he said mom did my top half and you can go down below. So I soaped his butt and then he turned around and he said wash me good and laughed. So he was about 5" and very hard and he said he can not cum yet, but I jack off all the time. Mom said he can make her cum and often does.then mom and I soaped each other down and I fucked her under the running water. She came a few times and she said pull it out and I am going to jack you off. So she was jacking off my cock and her kids were watching her and I was going to cum and I squirted all over her face and she said she loves cum on her face. Then she was using her fingers and licking my cum off them. Both her kids helping her licking her finger. Then I came on her pussy and they licked her clean. Her side of the family all started to have sex at early ages. It was always fun going to the beach with them.
