getting NTR'd by a big futa lady is one thing but but watching in real time as your (now ex) girlfriend stops protesting and gives in to the stink of her thick cock gotta hurt, ESPECIALLY if that cock is busy trying to churn you into it's next hot load...
but hey, on the bright side, at least once she's done crunching you away in there you'll go inside your girlfriend one last time! very very deep inside her...
