text: what would you do if you thought your hubby cheated with your sister?   investigate further and discover the truth. if it was a false alarm don't ever mention it to him or her. if he cheated talk with your sister first and tell her you have a fantasy of a threesome with a woman and your husband and tell her you need someone that can keep her mouth shut and ask her if she can do it as a personal favor to you.  after she agrees talk to you husband and tell him you have a fantasy about a threesome with another woman and ask him if she knows someone that can keep her mouth shout. he won't suggest your sister. but he will agree to bring a female friend. have fun and after a few times suggest your sister for a threesome and have some more fun. then invite a male friend (a black with a bigger (censored) than your husband) and have some more fun.  or get a divorce  the choice is yours
