Searching for a FanFic

[Nutz]

I remember one scene from a fic, where Penny followed Sheldon into a brothel and watched him through, what she though was, a one-way glass.
I have no idea of the title, though.

I believe the story was The Mystery Redhead Situation by Shenny Fan. Penny was just looking for a fun night teasing her favorite Whack- a- doodle. but she was about to get a whole other level of fun. Unfortunately the Story and Account has been deleted

 
You can try this one:
Affectation by tx-fictionqueen Newly single Sheldon finds himself plagued by urges that were never there before and he discovers an unconventional way to cope. It isn't long before Penny finds herself along for the ride. Dark Sheldon.  (Sheldon/Penny) (M) This is abandoned and might not fit what you’re expecting.


There is also one where Sheldon isn't the virgin he pretends to be and has sex with Women against Club alley walls. Penny is intrigued and finds herself wanting the full "Sheldon Cooper" experience. I cant remember the name right now, but I'll see if I can find it.
