What I like to do is remix stories (some real some fake) So like I will be talking about my dog had a fight and then add some fake thing about what I did lol. Usually when I throw out my first story I usually use other parts of the story to transition to other topics like sex. Before i had went out and started approaching I had read alot on how to construct stories and now my stories are pretty solid. Always have girls come back to me an say a comment from one of my stories.
Best stories are the ones that catches the persons ears, you wouldnt want to say "So I was at the beach" you want to get them hooked by getting str8 to the point
(assume you did some opener about the beach)
"At Melon Beach this bald head guy was.."
Then you want to include some social dynamic (sh!t that stirs a problem,emotions, etc sh!t that you find in those gay ass love novels)
"...drinking on the beach, now melon beach is a great nudist beach over in Cali and this guy is just sitting there drinking and my ex gf is talking to my other ex gf and laughing at the guy..."
The girl is probably wondering...What is the bald guy going to do, what is the relationship with his 2 ex gfs toward each other and what is there relationship towards him. It also social proofs you because you have girls how like you.
"then the craziest thing happens I bust out the stereo on the beach and my ex gf mimi starts to dance and now its looking like a mini beach club, but the bald guy decides to join the party and starts grinding on mimi next thing I know he grabs both of her breast and just start making out with her. Me and nana are there dieing, after we left me and nana are there imitating infront of nana how he started dancing on her"
you hook her again so she will be able to picture it even better and then you sat there and laughed so it shows your not mad about the break up anyway and that you are a fun guy, and your comfortable with everything that went on.
thats just a little example, of how I put stories together, its always good to leave mystery and make sure you convey your personality.
