It was an exciting time for me. For everyone, really. A new test subject was ready for insemination, and it was my job to prepare the subject for what she would experience. The subject lay perfectly still on the massage table. She had this strange, serene look on her face with a hint of contentment. That was new. Most of time the facial expressions are blan...

"So this is the boob job project, right?" asked the heavyset man as he descended the staircase into the bowels of Connecticut Pharmaceuticals.

It looked like an attractive way to pick up a little extra money. The ad was for volunteers for physiological research - either men or women. The fee was for each day's service, in a clinic, and it could be done on a weekend. To a couple in their forties, with college expenses looming, it seemed a good way to acquire a bit of extra cash.
