Some years later

17 years have gone by and you and your sister have fucked your father like rabbits in heat. You all slowly went your own ways. Your dad found a new wife and you found a man that you love.

After your first girl you had two more kids with your husband. One was a boy the other a girl. Your first born girl is getting ready for her 18th birthday party. An of course you and your father have plans for this its been something you and him have talked about for a long time.

You want your father to take her virginity just like he did to you. You sat down a few years ago and talked with Beth about this and told her about what it meant. She loves her "grandpa" or as she found out dad and that her mother was also her sister.

Which she found be be a little odd but explained so much. She never had any real heath issues just Asthma. You made sure to have her looked at by doctors. You family doc who was a great friend as well. Informed you the these kinds of relationships do not cause problems unless it continues on thought-out the family lines for a long time.

In other words your dad cant knock her up or more serous medical issues could arise. But she wants to do this and she wont use any protection if she ends up pregnant she said she's fine with it. But you aren't sure you want that but it is her choice.
