Sit in the chair beside Rochelle and wait for Tim?

I sat down in the lawn chair beside Rochelle. She had the back of her chair tilted slightly so she was lying back a little, able to catch more rays. I couldn't tell if her eyes were open or closed as she was wearing large round sunglasses.

"Did you remember your sun screen?" I joked, remembering her lecturing us before the trip.

She laughed, and turned her head to look at me. "Yes," she said. "Well, sun tan oil anyway. I have to be careful though not to overdo it." With that, she reached over and just slightly lifted the right shoulder strap of her bathing suit. "I don't want to be multi-colored."

She was making a joke about being tanned or burnt or white or whatever, but I wasn't really paying attention. When she lifted the strap, she pulled her boob up slightly and I was mesmerized by the jiggle of her soft breast. I could see the curve of her boob as she lifted the strap. I don't think she realized how much skin she showed because of how she was sitting when she made that little movement.

My cock quickly got hard in my swim trunks, and I had to adjust the way I was sitting slightly so she wouldn't see the tent it was making.

"No," I stammered, staring through my sunglasses at her cleavage as I sat there.
