While Ty shut her eyes and allowed herself to rest after getting fucked by the handsome man atop her, she saw how her body was working to ensure the act she and Eileen had just partaken in had the outcome it instinctually desired. She saw how deep inside her, what used to be his testicles had produced an ovum, pliable and desperate to get fertilized.
She then saw how, thanks to her orgasm making her cervix dilate, a massive amount of Eileen's semen had seeped inside her, and now the innumerable sperm were rushing towards the ovary containing her egg. It felt unreal to consider all this was happening considering she and Eileen had only been in their new genders for a few minutes, but she could tell it was inevitable. Eileen's seed would fertilize her egg. She was about to get pregnant.
Sure enough, her egg was soon surrounded by energetic seed which tirelessly chewed away at her egg's walls, and it caved to them willingly; this process had nothing to do with conscious desires, Ty realized, it was instinctual and irrepressible. One of the sperm reached the centre of Ty's egg, fertilized it and claimed it as its own, guiding it into the womb, making it divide and implant itself, and getting her pregnant.
Ty opened her eyes and saw as the handsome man above her withdrew from her. She felt his thick white seed dripping from her, and saw translucent and white juices covering his shaft, and was surprised by the intimacy she felt for him now. This man had bred her, and she would bear his child. When he leaned down with a satisfied smile and kissed her, her heart fluttered.
