Decoys [2004, USA, horror, DVD5]

In St. John College, freshmen and best friends Luke and Roger meet sexy, blond cousins Lilly and Constance in the laundry of their building. They are next-door neighbors, and the experienced girls invite the young men to visit them anytime. When Lilly forgets a package of coins in the laundry, Luke goes to her room to return it. The room is empty, so Luke starts to snoop around. When the two girls suddenly arrive, Luke hides in the wardrobe. While peering through an opening, Luke sees Lilly with many tentacles on her breast. Luke tries to convince his friends that the girls are aliens, planning to attack Earth, but nobody believes him. Meanwhile, some friends of theirs are found dead, with their internal organs completely frozen.
