Not much...

I looked at her, and noticed she wasn't really wearing much at all. She had a cropped t-shirt, and the same bikini bottoms. She looked very hot - and she didn't seem to be wearing a bra under the shirt.

She sat down, handing me my drink. "Thanks," I said.

She took a sip from her drink, and seemed to accidently spill it on her shirt. "Dammit," She uttered, "Well - better take it off then."

She took off her shirt - I couldn't believe it. I had a huge erection showing a little through my shorts.
