What Keeps You Alive (2018) is a lesbian horror story about a woman who married someone that it turns out she barely knew. The two spend time in an isolated cabin where she finds out that her gorgeous wife actually killed her first wife and is going to do the same to her. Now she has to do her best to survive and get far away from the woman she thought she loved. The women are played by Brittany Allen and Hannah Emily Anderson. Hannah plays the sadistic killer who also displays killer pokies in her white tank tops. One of her tops is even see-through as she gets frisky in bed with Brittany who wears a bra and underwear. Brittany is seen nude in an overhead shot while she lays in dirty water that slightly obscured her best bits, but we definitely can see her boobies!
