Baxter: She could be thinking of many things. With the falling leaves comes the colder weather and she won't be able to wander around in her bikini outside soon. Or she could be looking at the red leaves, knowing her bottom will match them if she doesn't rake them all up. Or she won't be spanked with saplings but rather a less pliable riding crop or cane. Yes our dear friend Hilda's thoughts are on her behind, as they should be, the naughty wench. 

Rosco: “I know Rosco’s watching, I can feel his naughty eyes. That neighbor boy has scarcely missed a chance to ogle me from behind that window. I know I shouldn’t enjoy teasing him like this but I do. What’ll I do next? I plan to catch him so I can give him a sound spanking, then make him give me a long slow wet kiss between my ample thighs. Oh my, I’m so wet just thinking about it. C’mon Hilda, how can you capture that pouty lad and make him your love slave?”

(With apologies to all those who’d prefer to see Hilda’s big bottom getting spanked)

KDPierre: Taking her ease, she felt a cool breeze, causing a draft, right up her aft. 

Prefectdt: "Is that a Martian tripod coming towards me?"

Sorry, as soon as I saw this image, all that came into my head was the song Forever Autumn. From Jeff Wayne's War Of The Worlds

Red: The geese are flying south, to enjoy the warmth. I wish that my bottom will have the same warmth soon, and often!

Simon: "It's autumn and freezing so why am I raking the garden in my underwear" thought Hilda.

Rich Person: "All the leaves are fiery red. Why isn't my bottom?

Ronnie: He told me to clean up the leaves and then come inside for my spanking, I hope it's a hard one.

Wendel: My love is going to change the color of my bottom tonight.

Alan: If I just leaf through these leaves, maybe he won't leave tonight without spanking me.

Hermione: He'll never find the paddle under a big pile of leaves. But what if the wind blows? Or if he decides to burn the leaves? Better not try it.
