Puck/Rachel

I can't remember much, but what I do remember is something like:
Some glee members in one car, being dropped off at their homes. I think Rachel and Puck are the last two left.
Rachel is sitting on Puck's lap in the back. I think there is frottage going on, and I think Santana is driving because I remember her watching them in the mirror.

I feel like I read it on LJ. I looked for it in gleekinkmeme on LJ. I thought that's where I first found it, but I'm afraid that the fic might be deleted because I can't find it anymore. I also looked for it on FFN and AO3, but I couldn't find it there either.

Please help me? Thank you. :)
