Five local business men in Dover, New Hampshire, belong to a club called The Snowshoe Club. At a club meeting, these five men decide that they want girlfriends they can have sex with. One among their number, Elliot, the one in charge of getting things done, suggests that they might get one girlfriend and share her among the five of them. They agree that such a scheme would be a practical idea. They dispatch Elliot, who finds a college girl and commandeers her to their purposes.
Eva is young and beautiful; the men love her, but she tends to be a bit of a flirt. Elliot decides that a punishment may be necessary in order for her to correct this unladylike behavior. He ties her up and spanks her in front of the others. Her behavior improves, but the beneficial effect doesn't last. In less than an hour she is back to her flirting and teasing, walking in a way that causes her t**s to jiggle, sitting in a way that causes her underpants to show.
Over a period of weeks, Elliot steps up the effort to correct her behavior. Eva becomes addicted to the punishments, and in particular, she craves the ravenous hunger in the eyes of the men during her torment.
After each punishment, Elliot unstrings her and lets the others go at her like hungry wolves. Only when they have had their fill of her, does he partake of the pleasure for himself.
