Two sisters and two male friends, not related, explore a, I dont want to say haunted, but mysterious, house. Something about the house increases all their libidos. Turns out the house was just the focal point, and the whole town was in some paranormal hot spot. The author had several stories in the series, but suddenly stopped posting. The stories were good enough and hot enough though, that I'd like to re-read them, even if it is unfinished. I cannot recall the title or author though, so I'm stymied. Y'all always seem to come through when I'm in this dilemma, so can anyone help?
