Laura was still determined to have some fun with female Nathan or Emily and she had just the idea to do it.
You see when Laura was in college she entered a period where she was tight on money and she got desperate so she started working at sex shop/porn studio she intended to leave the studio once she had enough money but become good friends with the owner and eventually when the owner retired she was the one who took over the company!
So Laura had an idea. She went to the studio Nathan got the part at and pitched something to them, A series of nsfw ads and porn videos featuring Nathan/Emily to promote Laura's company as well as the sitcom and surprisingly the owner of the studio agrees and on the same day Nathan is filming the first episode he will be filming 3 porn videos as well as photoshooting for some ads for buttplugs and dildos. You decide to hide this from Nathan until the day of the filming.
