I [M] fucked someone and it was weirdly good (short story)

To the point, I am a straight guy but I was caressing this dude. It felt somehow right. I undressed his jean and underwear to find out there was a vagina instead of dick.

It was already so wet. My dick was already in there as if it was a slimy vacuum. I went from back and rub the clit.

Given the situation I got too excited too quickly and came. He said

“Why did you cum inside? It’s so unsafe.”
“Sorry, couldn’t control.”

And… that was the moment I realized it was my wet dream. I’m mid-30s and still having it once in a while haha.
