I have tried the Lit search engine MANY times and also I have tried searching Lit through google without luck. The story is about a (told in the first person from his perspective) husband that suggests that his shy wife go on a date with a black man that is visiting their area on business. She does not want to go, but, he says, just go on a date with him one time and so she says yes. She agrees to tell him all about it when she comes home. The black man and the husbands wife go out to dinner and then dancing and the man is a perfect gentleman. The man is still in town and the husband convinces her to go on a second date and again they go dancing and then park in his car before coming home. They kiss and she says they shouldn't do any more and he doesn't push it. The wife tells the husband later and he encourages her to do whatever she is comfortable with the black man. She again goes on a date and this time they park and she touches the mans cock and it is big and she is turned on. Now she decides to follow her husbands advice and have sex with him and she describes it at amazing to her husband later. Then she asks to have the man come to their house for dinner and when he does they have a threesome and the wife gets both men off. Does this sound like a story you have read and if so can you help me find it??? THANKS!!
