After three years together, a man checks his sleeping girlfriend's phone for the first time and finds recent videos of her sucking and eagerly fucking a stranger. More clips appear, including rough BDSM play that clearly thrills her, and his heartbreak turns into an uncontrollable cuckold fetish. When she catches him snooping, she admits that she still loves him but cannot forget her lover's cock. He asks to watch her being taken, beginning a strange relationship in which he secretly views live calls of her climaxing with another man while he masturbates in misery and pleasure.
