After her mother remarries, Leah moves into her stepfather’s mansion. Heavy rain causes her bedroom to leak, forcing her to share a tiny single bed with her cold, rebellious stepsister Isla.
Trapped in a cramped room on a stormy night with their parents just outside the door, Leah’s repressed desires ignite after accidentally catching sight of Isla’s private moment days before. As they lie pressed tightly together, hidden touches and breathless whispers stir forbidden longing between the two unrelated stepsisters.
