A day at the beach having fun

A day at the lake with my son and his girlfriend. It was a hot day in the 80s. And my son's girlfriend is on the blanket next to me. She was wearing a baggy bikini bottom and a top that didn't fit and neither of them were not good at keeping her covered up. He is only wearing baggy shorts very baggy and you can see his cock when he moves them just a little bit. I layed down on the blanket and she is giving me a good shaved pussy show. After a hour of heat she went and got into the water, and that made it harder to not look at her pussy and tits. The only thing you could not see of her tits is the hard nipple but her big circle around the nipple is easy to see. And her pussy even though she is shaved clean below is hanging out too. My son dick is hard and hanging out the right side he's about 10 inches long and his shorts are only 4 inches long. She is rubbing his head and nuts and he is getting super hard and the shorts are not doing anything to cover it up. She has him sitting with his legs crossed and his cock looks like he's 14 inches long and very fat. LoL the girls are all watching him and a few of them have asked me if I am his Dad, I said yes I am they are starting to watch me, I have on cut off shorts and one girl asked me if she can sit next to me, so I layed on my side and I had my knees curled up and she is moving her back in to my Dick and then she is going under my shorts leg and I don't have any underwear on she's masturbating dads cock. I asked her if she wanted to have a drink and we went to the cooler and I make her a rum and coke. We are now talking about how he looks and she said that she wanted to suck on my cock. So I opened my fly and she is sucking my cock off he is now behind her and he slipped out his hard on and she said it is in her butt and she was moaning when he shoved it in her butt. Then dad put it in her pussy and she is going nuts then they both cum and she said that she was going to the lake. I think I know what we are going to be doing for the rest of the day.
