I think it's been a year since I've read this story but the premise is this: A rich man travels in his mobile home / Van and meets a (as for missing a good word for her) Milf on a beach and they have fun there. Later the day he meets her again after her car has burned down and she has nowhere to go with her daughter and he takes them in.
This part I'm not sure if it is still the same story or a different one: later he also comes together with his daughter who is in love with him and they have a big happy family afterwards.
If anyone has the name for the story or stories (in case that are two different stories) I'd be thankful.
Have a nice day.
