First of all, different people like different things! Even if you favour, say, BDSM stories or Love Stories people have favourite ways to treat the subject. Some like the writer to cut to the action very quickly, some prefer a longer lead in....
However, some across-the-board advice....
CHARACTER.
(Draw your characters well, let's know who they are, where they are and why they're about to do what they're about to do.... Describe how they're feeling as they act... Excited? Ashamed? Abandoned? Helpless? In Control... etc.
DETAIL
(An aid in making your story more realistic is to include a degree of detail; what the protagonists look like, what they're wearing... Describe the setting, what kind of Room, Car, Car-Park!!!
PLOT
(Have a start, a middle and an end, a climax if you will... Makes us imagine what might happen next)

I have two pieces of advice for your first story...
First, don't forget to put sex in it since it is a "sex story site"...
The other, and I think more important piece of advice is to write it up and post it without worrying about trying to make it "perfect"...in spite of what some here may tell you about editing and re-editing...
I think the best saying I've read in a while I saw on a writing blog recently...it went "Don't get it right, get it written."....
You have no idea how many people I've seen post in the forums here in the last couple of years asking advice on their first story and never actually posting one...your first story will never be "perfect"...neither will your second, or third...
Just write it and move on...
I don't have any specific pointers, I'm sorry, but the hallmark of a good story is when you are disappointed that it has ended. So it's a combination of skilful writing, nice mental images and an interesting plot, I suppose. I find a lot of erotica very 'mechanical', kind of like, "he did this, she did this, they did this (sideways), and then they came" which ain't so great. I like it when authors make a real attempt to paint a picture in words.

I like to read about first male on male stories. Should have many details and what you were thinking at the time.
What about tips on writing an incest story? I would love input from men and women
My first time m2m experience is somewhat taboo, but since it happened many years ago and the person it was with has long-passed away.....He was older and it was oral. At the time, I was the person who wanted it to happen and I have never felt bad for making it happen. It was awesome and I still dream about it.
