Joyful and loving incestuous sex is the topic of this steamy “Greene Shorts” erotic short story. Erica and Rob are a teenaged couple who love each other dearly, and they don't let the fact that they're brother and sister stand in the way of that love. Yielding to the inevitable, their parents have decided to give their blessing to the couple's sexual relationship. And the parents find that listening to the passionate lovemaking of their son and daughter every night acts as a powerful aphrodisiac in their own sex lives. But Terri, mother of the two lovers, is beginning to have second thoughts about allowing this sibling incest. It's hard for her to keep an open mind about something that's so universally condemned by society, especially when it seems that she can't turn around without tripping over the sexually entwined bodies of her children. Erica, Rob and their father Dennis come up with a plan to help Terri feel more comfortable about incestuous love. Will they be able to convince her of the joys to be found in truly close “family ties”?
