by Happy Husband
This is a great story, happily moving away from the monster cock syndrome. This couple returns as real 50ish people, who it seems are much more likely to swap than engage in mindless orgies. Only criticism is the supposed ruination of Bonnie's ass by the monster cock. If one fuck will stretch her out forever, she will need depens for the rest of her life. Author might get more comments if he told us more about himself and his wife.
If this is a true example of your work, then I think that I can safely skip the rest.
