You wash her hair.

You squeeze some onto your hand and place the bottle on the ledge. Rubbing your hands together, you create a bunch of bubbles to then stroke into her hair. Her form from this view is still beautiful, but thankfully much better than any previous one. You sit in the water behind her and continue to watch her hair.

It's like a massage to her. She makes soft, happy noises at your touch and smiles wide.

"Oh... That feels so good," she coos.

You continue, wishing that she was speaking of something else entirely. But for now, you simply clean.

"Yes. Oh gods yes. This is amazing," she whispers before a lengthy joyful moan.

She eventually dunks down into the water and washes out all the soap, filling the hot tub with bubbles. She leaps back up from the water with a red face and a soaking body, giving you a generous view once more before she dips back down into a sitting position. She begins to frantically wipe dry her eyes.

"Phew! You're really good at that. All right. Turn around and I'll do you."
