All I remember from this one shot is that it's incest, the older sis ran from her lil bro and got married, bro comes over and stays the night waking the sis up threatening to set off the alarm so her husband would wake up and see bro raping her, sis gives in so he'll turn off the alarm only to learn at the end he'd set a second alarm that goes off. Also sis and husband may sleep in two beds next to each other? And she's really scared of her bro.
