So, for the story I'm working on, I'm writing a lovely, wholesome song about a woman and her pet donkey. It is a beautiful donkey, and everybody who meets the young lady always comments on what a lovely ass she has.
I have a few ideas for some of the verses. For example, one man might decide to take the donkey for a ride, but the donkey goes out of control and he ends up riding her ass all night. Perhaps two of the characters are shovelling hay for the donkey's dinner, but they fall over and end up rolling in the hay. Maybe Jack takes the donkey for a ride, but his foot gets stuck in one of the stirrups and the lady has to help Jack off the donkey... You get the idea.
So I've been searching for some innuendos and euphemisms for the song, but I can't seem to find anything useful. I either get suggestions like "making love" or "doing the nasty" which can't really translate to anything more innocent, or they're really weird expressions I've never heard before, like "Sweeping the chimney" or "Whitewashing the picket fence" where I'd be worried no one would even know that they were innuendos. So... They need to be obvious innudendos, ones that everyone will have heard of, but also ones that could mean something completely innocent. For example, if someone has a very cute pet cat, there's nothing wrong with giving her pussy a little stroke.
Any suggestions welcome, don't worry about suggesting something too obvious because I might not have thought of it yet. Really, the more obvious the better. ^_^
