I was at a party being thrown by my boyfriend’s boss. He was a large imposing man 20 years older than me. It was half way through our first conversation that he put his his long finger up to my lips, and I instinctively opened my mouth. That fact that he had the balls to do this right in front of my boyfriend made me all the more wet. He told my boyfriend to grab him another drink from the bar and offered to give me a tour of the house.
