Give Satisfaction

I have a question about the "Jeeves wearing black leather gloves, solo" (https://give-satisfaction.dreamwidth.org/2406.html?thread=16486#cmt16486) prompt. I think Jeeves wears these kinds of gloves but idk if Bertie does, too. Does anyone who's familiar with canon know if he does? Can I just assume that he might? Or would that not be a safe assumption because it's more like part of Jeeves's uniform/not something an aristocrat would wear?
I ask because I want to know if the point of this prompt is "Jeeves is into leather/masturbates with his own gloves" or if it could be "Jeeves is into Bertie and therefore masturbates with Bertie's gloves."
