I come home from a night out and end up confessing to you how I've been fucking other guys behind your back, the more I tell you about how much bigger their cocks are, the more you get turned on. I tell you about how the bigger cocks make me cum and you don’t and how I let them cum inside me then came home and fucked you afterwards (and you thought i just felt really wet but it was another mans cum) You get so turned on that you eventually cum in my mouth.
