In the kitchen Lisa's mother, Mary, had regressed back to her 24th birthday. While holding her 8-month-old baby girl Lisa in her stomach. Mary noticed Gary, a 26-year-old Mary's husband, whom had just arrived back from his work. Inside the womb Lisa was quite distressed as she finally became aware what had just happened but couldn't move, open her eyes or speak. All she could do is to sense and hear. Suddenly Gary grabbed Mary's hand and begun to undress her. Mary begun to sweat bullets as Gary begun to fuck her on top of the living room's floor. He begun to immediately insert his solid iron rod inside Mary's wet pussy and just like that both of them were fucking full speed in missionary position.
Gary had no idea why he was doing this but the overwhelming horniness just made him do this. Mary also didn't question anything that was expiring as she was receiving the most intense sex she had ever had. Inside the womb Lisa shrunk steadily and begun to go even further in the regression. It was like as if the whole world wanted her to cease to exist. Every thrust felt more orgasmic as Gary's ironworks factory begun to produce steel. The engine was pumping twice as fast as the pistons pump action went from two thrusts a second to eight. The sound begun to resemble a formula one car as Gary's cock was rapidly exiting and entering the pussy lips.
Gary could only moan in pleasure and pound Mary as both of them had become younger by one year. Mary hold tighly on Gary as he came inside her vagina like a cake frosting. But that wasn't all. Gary wasn't stopping and kept fucking Mary. In the womb Lisa begun to loose definitions what made her human and was slowly ascending into a pile of sentient sperm and egg. She was aware of both of them as Gary's new sperm entered the egg. Lisa felt a presense near hear as if someone had touched her shoulder.
The small egg spit out the sperm and begun to shrink down in size. The sperm that was other half of Lisa begun to rapidly swim backwards back to it's origin.
Gary's ballsack.
Mary, now age 22, and Gary age 24 were still screaming and moaning in pleasure as finally the single sperm cell swam back in to the Gary's balls. In that moment both of them stopped immediatly and were panting in exhausting. Both of them having no idea was happening.
