Much to my delight, she was dressed in one of my favorite postage-stamp bikinis. That was the style which easily passed the 'boner test'. My erection was previously at half hard but immediately went to full hard and standing out proudly. Sally noticed that her two friends were skinny dipping so she shed her miniscule suit.
