I knew after cumming inside her pussy so many times she would be pregnant, but I didn't want to wait months on end for the results. So I wished for my little sister to be 5 months pregnant, and the changes quickly happen. She lets out a loud moan as her belly slowly expands, till it was about the size of a volleyball. A wave of relaxation, pleasure, and happiness ran through her whole body, and I gave her a hug and a deep kiss with satisfaction.
"I'm finally pregnant, big brother!" She said with a big smile, her ass still leaking cum and her pussy juices flooding from her slit. "I'm preggers with our baby brother!"
"That's great, little sis," I said, sitting down on the couch and letting her straddle my cock and impale herself on it. I was fucking my pregnant 9 year old sister, and I couldn't be happier and its all thanks to this ring. Mom and dad eventually came in the living room to congratulate us, watching their children fuck like it was just a normal day before leaving to do other things.
I wish for her pregnancy to advance to 9 months now, and cum deep in her pussy, causing my sister to moan and her water to break on me. "B-Big brother it's time!" Our parents rush back in to witness the birth, having a camera out to capture the moment.
"Ohh Okay!" I groan and slid my little sister off my wet dick and lap, laying her on the couch and wishing for the birthing to be painless. She moans and starts pushing, the head coming out and eventually the rest of the baby in just a few minutes. I wish for the umbilical cord to go away, and my sister brings our newborn daughter to her C cup breasts for a drink. My parents cheer and congratulate us on their newborn granddaughter, going away to come back and clean up the mess for us. I cuddle Melanie into my arms as the baby hungrily suckles on her milk-filled boob, kissing them both on the forehead.
"Lets name her Alice." Melanie softly said, and I happily agreed. We spent the rest of the day naked on the couch as a new family, before going to bed. I wish for a crib to appear and place little Alice in it, cuddling up with my sister as we spoon our naked bodies together.
