Gwen finished feeding Leon and cuddled him closely while he drifted off to sleep. She sighed a little. Ever since she found out she was going to be a mom she had desired a girl, she had wished and hoped and expected but when Leon was born her hopes had been dashed. She still loved him but the last thing she wanted to do was raise a rambunctous boy who got messy, was a troublemaker, and grew up to be six foot four with the appetite of four people. She wanted a nice calm and collected girl who wanted to play with dolls instead of loud action toys with lasers and explosions.
Gwen was pretty deep in thought when she reached into her bag and accidentally touched something slimy. She gagged and drew blue seaweed out of it. At that very second Leon phased through her belly and labour pains wracked her body. She painted and groaned for a good five minutes before they subsided and she put her hands on her heavily pregnant belly and sighed. It began to shrink very slowly and soon enough she could move a little. She reached into her bag and drew a book out of it before beginning to read. She zoned out, the beach becoming a blur while she read her book in silence. Her belly continued to receed and sitting became easier as she became less and less bloated. By the time she came to she was four months pregnant and the beach was closing. Gwen packed up her stuff, got into a car, and drove away from the sandy shores. When she arrived at her apartment, a beat down and bedraggled place she was three months pregnant and when she finished cooking dinner for herself she was only two. The night progressed with her body reverting to a pre pregnancy state and when she crawled into bed and closed her eyes she was indistinguishable from prior to her pregnancy.
Sleep came easy but at some point in the night Gwen was awoken by intense pleasure in her nether regions. She opened her eyes to see Joshua Yandrennis atop her with his dick in her nude vagina. She gave a moan and her body kicked into autopilot. She wrapped her legs around Joshua’s body as he humped her harder and harder. The sperm that made up half of Leon made its way to his dick. Gwen was in bliss and barely noticed. They continued to fuck as Leon retreated back into Joshua’s ballsack and embedded himself in the wall of the testes. Leon began to change. His haploid cell becoming diploid. An X and Y chromosome present. A perfect copy of Joshua’s DNA. However Leon then split in half becoming two sperm. Except this time the sperm that matched Leon had an X chromosome instead of a Y.
Joshua and Gwen continues to fuck and eventually flipped over into doggy style. They were both in bliss and when Joshua released a jet of sperm Leon was quicker and more accurate than any other. Joshua and the other sperm faded while the now lone sperm smashed into the side of an egg and fertilized it. Gwen fell asleep again and as the night progressed her belly expanded by months of pregnancy. When she woke up she was nearly due again and after her shower while she was eating labour pains struck her and minutes later she held a healthy baby for in her arms and was in the process of breastfeeding her. The quicker regression and progression halted and Gwen was left holding her three week old baby, Lucy and smiling at her.
