This bunny comes from a line in "All That There Is" by jule1122, which was a full fic written for the Small Things Made Large challenge over at qaf_challenges. I literally stopped in the middle of the third paragraph of it and needed to post this because I think it could make one or multiple incredibly hot/interesting fic(s): "Either way, we’d end up fucking while rolling around in paint. But this isn’t a movie, and we’ve fucked in paint before, an experience neither of us plans to repeat"
So there's the bunny: Sex "in paint." (And if you want, why would they not want to repeat it?)
