CLING FILM SEX!! Just the idea of it was so erotic, and the mutual wanking session with them watching each other was HOT. They had these scenes with the cling film in Pushing Daisies and I really wanted to incorporate that into my fic. I thought of using a shielding spell, but that was so impersonal. They probably wouldn't even have been able to feel the warmth of each other through that. It was also why that didn't become the solution for their dilemma. At the beginning I was thinking of using that, but yeah, who would've liked to walk around with a shielding spell 24/7 and never be able to touch anything and feel it ever again?
