Cucked by Your Girlfriend

I'm your girlfriend and i've convinced you to let my ex stay with us while he's in town. while we're getting ready, you notice me putting in a lot more effort than what i usually do. i assure you that you have nothing to worry about, and i only ever like him for physical reasons. i sense your insecurity, but i tell you that tonight, my ex is going to listen to me get fucked by a real man, and the only reason i'm dressed up is to make him extra jealous of us! he arrives, and i'm immediately flustered, ignoring you in favor of him. i tell you he must be exhausted, and i just wouldn't feel right having him on the couch. you grudgingly accept, but are wondering what happened to our plan? i tell you,i've changed my mind, and we can do that when he leaves! i promise, i'll even leave the door open so you can see everything. a few minutes after i turn the lights off, you hear giggling and whispering in the dark, then kissing....and then moaning.... you can't help it anymore, you have to turn around and see what's happening! i apologize, but make eye contact while he's inside of me, telling you how much i've missed his dick. i make you jerk off to a real man fucking me.
