The manga I can't remember the name but the story was the lovers were step brother's the older one was a salary man and his younger step brother was a famous model/actor or whatever. and the uke (older brother) keeps having dreams that he is having sex with the younger brother but it turns out he actually was lol. Anyway I thought it was cute and just wanted to read it again for fun thanks 😃

This won't be helpful at all but it sounds like something Minase Masara could have written.
Also, a quick search led me to Gokudou Darling. I never read it, could it be it?

Nemureru Mori (TOJITSUKI Hajime) is definitely not it but the plot you described rings some similarities (twincest).

It's the Art of Time, it's the Art of Life--
Of the player and the craftsman,
Of the writer of songs, of the creator of love,
Of those who will follow, of those who led,
There's no other way in the world ahead ♥

I don't want to detract from MirayAllen's post, but you can also try Otouto ni Koi Shitara by Sakura Ryou.
