Hia!! I’ve got a NSFW ask for a fic I read quite a few years ago.
I remember Steve had an unusually big dick and as a result had never had penetrative sex. I remember Tony taking it as a challenge? And working out ways/working up in size until he could take Steve. I think it was a friends with benefits to lovers situation and multi chaptered. I also remember it being reasonably popular explicit fics around the time it was written (although again, this was MANY years ago.)
Hopefully someone can help me!
Many thanks
