Using some random guy's cum as lube, is that really a bad thing. I mean after all, if she's getting what she needs, if he thinks it's hot, if the other dude doesn't care, why not.
There's nothing more that I love more than making my cuck put on his little cage, lay down, and watch helplessly as I let a real man fuck me into the bed until he unloads in my little pussy
Sometimes, when he takes me out to dinner, just the two of us, I love to surprise him too. I especially love the look on his face when I show him the last huge black cock I sucked and he didn't see it coming at all
