Yes

As your dad and sister are talking to your mom you snap your fingers again, then your sister slips under the table and starts giving your dad a blowjob and he blows his load in her mouth then she gets out from under the table and sits back down to eat. After your all done eating you follow your dad and sister upstairs and see your dad start forcefully fucking your sister on her bed.

You snap and watch as your dads mostly average penis grow from 8 inches to 15 inches and stretching his daughter, then his balls grow to the size of grape fruits and watch as they start to fill with a gallon of extremely fertile cum and cut his reafracry Period completely. You snap again and make sure your sister can pleasure her father and take the force of your dads new endowment.
