She and everyone else completely believed the children are of hers and your brother

The sounds of hands clapping together on the night of Christmas Eve is echoing around the dining table once your sister-in-law and your brother announced that they are expecting new set of children soon!

Obviously, you know otherwise. The twins in her belly are definitely the results of you took advantage of her in the toilet back during the Thanksgiving. After all, you unloaded a lot of semen into her womb that day.

Knowing that it is better that it remained as a secret, you decided to keep your mouth shut and enjoy the obliviousness of your brother and your sister-in-law, who are going to raise these twins as their own once they are born.

Eight months ever since the discovery of your sister-in-law's pregnancy during the holidays season passed by so fast and before you know it, your brother's wife has given birth to the twins. One of them is a boy while another is a girl.

As you are watching your parents are holding the two newborns wrapped in blankets in their arms, you cannot helped but smile. And while you do not know will your son might become like you or not, you have a feeling that your new daughter given to you by your sister-in-law through this secret affair with her might become like her in the future. And by that, you believed she might become a beautiful woman with such gigantic breasts like her once she grown up. But it is just a feeling. No ones really know what will she really looked like in the future.

"Congratulations to you two!" You said to your brother with a smile.

"Thanks!" Your brother said back with a smile also.
