A young woman works in a secret lab. She and her lesbian partner have wanted to help further science and have children. Girl A gets the job of researching alien life when it is brought back from a space mission.
She enlists Girl B, her girlfriend. She artificially impregnates Girl B with alien eggs. Three months later, after her girlfriend has lived in a contained environment, she assists her girlfriend in giving birth to the alien eggs (3-5).
I would play Girl A. We would only be playing the labor and egg-laying. I welcome any questions and am not picky about faces.
