After the incident I described in "The Innocent Young Intern", there was a lot of sexual tension between Rachael and me. Her flirtations were virtually non-stop; she kept asking for a peek, or she would purposely rub against me or try to fondle my crotch. This was a predicament that I never expected to be in. She was lusting after me and I was very concerned that her influential father would make problems for me if he found out I was sexually intimate with his daughter.
A few weeks later Rachael and I were working in the laboratory together and we were having a prolonged debate over whether to throw some samples away. I predicted that the professor would want them saved, and she said that he wouldn't. We decided to bet on his decision. The bet was that the loser would have to strip and stand naked in front of the other person for five minutes. I was so certain of the outcome that I would have bet the ranch. Sure enough, the decision was to refrigerate and save the samples.
Rachael turned 10 shades of red and acknowledged that she lost the wager, but there was never any discussion about when she would honor the bet. In fact, I told her that she didn't have to do it. About two weeks later Rachael walked into my office with a sly smile on her face, shut the door, and announced that she was prepared to comply with the terms of the bet.
She stood about five feet away and slowly unbuttoned and removed her sleeveless white linen blouse, revealing a very simple, white lace bra. Her breasts were small and the outline of her nipples could be seen through the thin fabric. Next she slowly undid her jean shorts, slid them over her shapely thighs, and let them fall to the floor. She was wearing skimpy panties that were cut high up her thighs and barely covered her pubic hair.
