My twin sister is out of town on business. Her husband comes home to find Me at their house. I tell him that She asked Me to keep an eye on him and make sure he doesn't go out and cheat on Her. Something tells Me that he had something dirty on his mind since I could see the bulge in his pants growing. I intend to drain his balls. I pull down his shorts to reveal a hard cock. I brought some lube, sis says he loves wet handjobs. Oh yeah I know all about their sex life. She tells Me everything. I know She'll appreciate Me doing this. I have another secret. She isn't just doing business on Her trip. She is going out, picking up men and having sex, every night. This information makes him even harder. Clearly he likes this nasty talk about his slut wife. That's good to know because there's more. She's taking a liking to black cock. I think She's becoming addicted. I know that his wife giving herself to multiple big black cocks is his secret fantasy. He's about to explode now so I have to slow down. I need him to last; but, the more details I give him, the closer he gets. I remove My hand from his cock but still he ejaculates, without any help from Me. I laught as his orgasm and his marriage get ruined. It's clear that he cums at just the thought of his wife taking other men. She'll make it official when She gets home, his place is now as Her cuckold
