In a desperate attempt to save money, a brother and sister move in together, their shared space becoming a pressure cooker of sexual tension. One night, as they huddle together under a single blanket to save on heating, their legs entwine and their breaths grow ragged. Unable to resist, they start to kiss, their hands eagerly exploring each other's bodies. The sister guides her brother's hand between her legs, gasping as he tentatively touches her clit. As they lose themselves in their passion, they're brought back to reality by the sudden chirping of their alarm, signaling that their makeshift attempt at saving money has come to an end.
