Rarity

Rarity was in need of money and when she saw an ad in the paper for a female test subject and that they pay handsomely she accepted it. She drove for an hour to a house in the middle of nowhere. When she knocked on the door she was answered by a pregnant woman who looked ready to drop twins. The woman introduced herself as Ala and welcomed Rarity into her home. Rarity then asked what the test was she was going to do to her. Ala explained that she was an engineer and a scientist and she has created a type of teleportation machine but she needed somebody else to test it as she couldn't in her current state. Rarity agreed and signed a waiver. They then went down to the basement to do the test. The teleported was just a raised platform with an archway. Rarity was told to stand in the red circle on the platform. Ala went to a control panel and started to turn on the teleporter. All she was going to do was send Rarity to the other side of the basement. The hoop started spinning and Rarity started teleporting through when a power surge overloaded the teleporter and the portal reached out to the two living beings in the area and sent them through. After what seemed like hours Rarity finally woke up and she noticed something was wrong when she tried lifting herself up and found a new weight on her middle. When she looked down she let out a bloodcurdling scream at what she saw. Her belly was huge and covered in stretch marks and her naval had popped out. At that moment Ala awoke to Raritys screaming. When she looked at Rarity and then down at herself she also started screaming. After 30 seconds of both of them screaming they stopped. Ala's curiosity then took over. She put one hand on her now flat belly and the other on Raritys fertile belly. She couldn't believe her teleporter actually worked kinda. Rarity and Ala got off the floor Rarity with a little trouble. Raritys body took the pregnancy very well. She was somewhat able to walk without having to truly waddle. Ala went to her journal and started writing down everything that had happened. Rarity on the other hand was having to get used to a new center of gravity. Ala then sated that she would have to carry the babies to full term because there was no way to return them. Ala had half of her fortune transferred to Raritys bank account to help out and also would be depositing monthly checks into the account. Rarity agreed to give birth to the kids and to keep them. Unknown to either of them their wombs and uteruses were also swapped with each other's.
