"I don't want nice and clean," Allison Tyler writes, "I want hot and fast. Dark and dirty. I want hardcore." H is for Hardcore delivers that special intensity that elevates sex from ordinary to hardcore. A novice visits a sex club for the first time hoping to finally live out her private fantasies, only to discover possibilities she never imagined. A woman and her married lover veer into dangerous territory when his wife arrives to claim what's hers.
