A play for school, practicing in the bedroom

--> STORY FOUND! A play for school, practicing in the bedroom

Hi!

I've been searching for what seems to be forever for a story, I've tried the tags and gone through so many stories. I can't seem to find the one I'm looking for, maybe some of you know what story I'm talking about?

I read it a long time ago, I think it was about a girl, inexperienced girl who had a part in a school play, with a sex scene- she needed help with the part, and this older guy/neighbor helped her some nights practicing the play with her mother downstairs. It was a story with more than two chapters, a lot of teasing. The guy was married, the girl had some tights with a hole in them w/o knowing in a scene....

I really hope some of you can help me??
And I'm sorry for my bad english, it's not my first language.

Thank you!

EDIT:
I found the story, I am so sorry you guys. I found it! Thanks for looking!

What was it?
