Help with the sunscreen

You are more than a little mesmerised as Tonya smooths the lotion over her upper arms and shoulders. She reaches up and back, trying to reach as much of her back as possible. At least that is what you infer she is doing; with her arms up and circling like they are her breasts are veritably dancing on her chest. You can see the outline of her nipples in the tight yellow fabric, pointing up and out on her perky, full breasts.

"You look like your struggling there, would you like a hand?" you inquire, wondering once again how you managed to get Tonya alone in a situation like this.

She simply swivels on the mesh, turning her back to you giving you an amazing view of the curves of her ass. "I was hoping you'd ask."

You take the tube from her hand and carefully start to stroke it over her skin. It feels warm, soft and smooth against your palm and fingers. She reaches back and draws her hair back over her shoulder. "Don't miss the spot under the ties", she instructs, referring to the string ties in the middle of her back and neck.

Those are your hands, on Tonya's body, this is even better than the last time this was happening and your mother woke you up to go to school. Your hands slide the ties up and down as you run your hands all over her back.
