Straddle for sure

I chose to test my luck and straddle her at her hips under the assumption it would be easier for me to apply the lotion. So I climbed onto the lounger and swung my leg to the other side of her body. I apparently scared her a little bit as she squeaked out a rather startled noise and whipped her head around to look at me. "What are you doing?"

"Getting ready to put the lotion on your back. Why?"

"Then what is with the straddling?"

"Thought it would be easier to put the lotion on. Is that a problem? I will move if you want."

"No. No don't worry about it. I was just startled. Sorry. Go ahead." It seemed to me that the first no came out as almost ****, like she kind of wanted this to happen. Maybe I was just imagining it though. Whatever, better get on with it before she gets suspicious about what I am or am not doing.
