Hilda needs some help

Hilda quietly waits as she dangles from the window. With nothing else to do, she casually looks about Sally's small room.

It's quite ordinary overall, with a small bed, a nightstand, and a little desk and chair in one corner, but as she is finishing her survey, she discovers something lying on the floor of the bed that gives her pause.

Is... is that... is that a pair of my panties on the floor?!

She strains to get a good look at the lacy garment sitting puddled on the ground, but before she can make a final determination, Sally returns sporting a bottle of what appears to be cooking oil.

"I'm back!" The servant proudly declares as she closes the door behind her. "I think this should do the trick."

"What are you going to do with that?" Hilda asks in confusion.

"I figure we can use this to help you slip free," Sally says as she opens the bottle. "Oh, w-wait..."

The girl stammers as a bit drips onto the floor.

"Um... I-I probably shouldn't let any get on this..." she says as she looks at her modest nightgown. "If it gets a stain, I don't think it would come out..." she says as she thoughtlessly shucks it off, leaving her completely bare once more. "Ok then..."

Sally pours a little bit of olive oil onto her hands and starts rubbing them together as she approaches her mistress.

"This might be a little cold," she says as she nervously, but excitedly, places her trembling hands on Hilda's soft, squeezable hips.

The naked noble gasps at the sensation.

"I... I'm going to start moving now," Sally says as she starts rubbing her oily hands all along her long-time crush's bare body. "Hmm, actually, I think we're going to need a bit more."

Sally steps back from her mistress and retrieves the entire bottle.

"Hold still," she says, as if Hilda had a choice.

"What are you... OOOOO!" Hilda gasps as Sally pours the entire bottle of oil onto Hilda's back and ass.

"We want to make sure this goes smoothly," Sally says as she discards the now empty bottle and starts to rub the oil all over Hilda.

At first Sally focuses on Hilda's hips, but soon she loses sight of her original intention and begins to repeatedly rub and caress other parts of the bigger woman's body.

She starts with Hilda's ass, massaging those two twin globes with her hands as Hilda sits there.

"Um, Sally?" Hilda asks as Sally continues to run her hands in a circular motion over that delectable booty.

"Huh?" The lusty little servant mumbles as she grows more and more distracted by Hilda's bare body.

"W-why are you rubbing there?" The naked knight asks.

"We might need to turn you sideways," the quick-thinking pervert says as she moves her hands along Hilda's back.

"Oh," Hilda responds.

"Same goes for your belly," Sally says as she explores her crush's body even more.

Hilda shivers and blushes as Sally's continued touching takes on a more erotic operation.

"R-really, I d-don't think you need to oil up my breasts..." Hilda weakly protests as Sally softly squeezes them and playfully pinches her engorge nipples.

"You never know," Sally responds as she finishes oiling up the quivering, panting noble.

She takes Hilda by the hands once more.

"Let's try this again," Sally says as she looks down at Hilda.
