Humiliated by My Alpha Male Husband

What started with an honest mistake ended up with me getting caught, by my husband, watching a porn film called "Untitled  Cuckquean", and being extremely aroused because of it.
I thought my husband had forgotten about that until now. He ties me up, gets me all ready for what's to come, and suddenly leaves the bedroom and comes back with a hot, brunette woman.
I can't move. Then, they force me to watch as their bodies clash, and their moans, grunts, and sloppy noises fill the bedroom. As if that wasn't enough, I'm eager to join them and clean their mess.
