Three girls and only one Billy? Can he keep up?

It all started when Susan accidentally called up a minor demoness named Pantallas with a Tarot card. Then, at Diana’s birthday party, they played strip poker, all three of the girls and Billy, but that was before anyone knew about the pill so nobody went all the way. Then Billy went to Viet Nam. This story is about his return two years later. They are all on the pill now and intend to take advantage of it. Is Billy up to it? Can he really take on all three of the girls? Oh yeah! And all at the same time, with the help of Pantallas. But which one will he end up with?
