Your father has invited you and your girlfriend to come celebrate thanksgiving at his place. you happen to notice that he is a little handsy with your girlfriend - a little too familiar, perhaps. she proceeds to let you know that things have changed quite a bit and that's she's actually been having a secret relationship with him. and here's the kicker - she is going to fuck him right in front of you on thanksgiving. you don't know whether to be upset or to take your cock out and jerk it to this new arrangement.
