Changing the rules of pregnancy

No sooner have you come inside your sister's beautiful 18-year-old pussy that you whip out your phone and check out the rules.

You remember that just as girls now decide when they want to get pregnant -- and Molly really wants you to knock her up -- that guys now decide the gender of the kid. You will the seed you filled your sister with to give you a sexy daughter.

Full pregnancy seems a little impractical, so you tap and change "Pregnancy lasts 9 months" to "Pregnancy lasts 1 hour".

Thinking on it a little more, you add:

"All people are born 18-years old with fully developed personalities."

You watch Molly's friends Gina and Chrissie sensuously pick up her nude, impregnated body and carry her out of the room, and then find your sister's friend Jennifer on top of you with a wicked grin.

You glance at your phone, and wonder at who you'll meet in an hour.
