A mare was walking around the edge of the Everfree forest when she felt something enter her vagina. She fell forward from the force of the creature. She then felt excruciating pain as it forced open the her cervix the mare passed out due to the pain. She woke up a couple hours later noting it was now nighttime. When she went to get up the mare noticed a new weight in her womb. She looked down and saw her rather large belly. She knew then she needed to get to the hospital soon. After a couple of tries she finally got up on her hooves. After walking a couple of feet the creature in her decided to make itself known. The creature was shaped like a foal but had tentacles on its back and one as its weener. After 30 seconds of thrashing it calmed down and went back to sleep. The mare on the other hoof was out of breath and knew there was gonna be bruising in her womb. It took 30 minutes to get to the hospital. Once there the mare looked at her belly before going and noticed it was larger than when she woke up. When she had awoken she looked ready to pop out a foal. Now she looked ready to drop triplets. She went into the hospital noting how deserted it looked. She went to the main desk and rang a bell. After 5 minutes of waiting Nurse Redheart trotted over. She went behaving the desk. She asked the mare what she needed help with. The mare thought how to go about doing this. She asked if she could have an ultrasound to check on her babies since she had fallen earlier. Redheart said she could do it since there were no other patients or medical personnel. There wasn't anything strange about the hospital being pretty much empty since it is a small town and there are rarely any injuries during the night why there was only one nurse. The mare followed Redheart down the hallways. Once they were in an examination room Redheart said she would be back soon with the ultrasound machine. The mare was waiting she felt the creature in her womb awaken. It started to move around and then it started kicking her womb harder and harder. The mare was trying not to scream. The creature then started to grow to adulthood. The mare saw and felt her belly grow faster and faster until it couldn't take anymore stress. Her womb and belly burst open and a fully grown tentacle stallion was right in the opening of the mares destroyed belly. She didn't even get to scream. The stallion then went to work on its first meal. Ten minutes later Redheart came into the room pushing an ultrasound machine with her head. When she looked up and didn't see her patient she was a little worried. Suddenly the door slammed shut behind her and the lights were switched off. She didn't have time to turn around before she felt a pony grab her and put on the bed with her hind legs pushed against the side of it. She then felt something prodding her entrance. She sniffed the air and instantly she was in heat. The stallion had released pheromones in the air that would work in his favor. Redheart felt the object at her entrance suddenly thrust all the way in up to her cervix. She felt a heavy set of testes slap against her. She felt what she called a dick somehow spread her cervix open and there went her rational train of thought. The dick then started to grow and completely enter her womb. It hovered in there before getting wider and pulling back slightly. Redheart felt the testes grow even bigger and heavier. She suddenly felt an object at her entrance inside the dick. After the first object moved through more started coming. They were about the size of an apple. She felt the first object drop into her womb. It was round and hard. She felts one after the other after the other until she counts about 25 or so orbs before they stopped coming. She guessed she had the appearance of a mare overdue with twins. The tentacle as she now called it pulled out of her but not before closing her cervix most of the way. The stallion released her and left the room. After about 5 minutes Redheart came to her senses she got up with some effort and trotted to the door while getting used to the weight between her legs. She got to the light switch and turned on the lights. She left the room to go to the bathroom once in the bathroom she locked the door and turned on the lights. She then went to the mirror in there and looked at herself. She was covered in sweat, her hair was a mess and now she could get a good look at her belly she saw she looks ready to drop twins. Her belly also wasn't smooth but covered in bumps from the eggs. She knew that creature had done something to her patient. Right then her heat came back on. She guessed the eggs didn't cut and she couldn't search around the hospital while dealing with her heat. She chose to let the creature have its way with her. She left the bathroom and started walking the she guessed the creature went luckily all the other medical personnel were out of town on a retreat leaving her there and given the ability to close up the hospital because there was a clinic in town. She trotted to the main doors making sure they were locked and there was a sign telling ponies to go to the clinic. After that she found herself in the maternity ward. She looked into a delivery room and wondered what it was like to be a pregnant mare in here. She got on the bed and put her hind hoofs in the stirups. In the lights shining down on her she saw that her hair wasn't able to fully cover her belly in spots leaving pink areas especially her now outie belly button. Suddenly the eggs in her shifted causing her both pain and pleasure. Her belly changed from round to an oval shape. She was about to get out of the stirups when the lights turned off and she felt tentacles latch around her hind legs keeping them in the stirrups. She smelled the musk of the stallion. She felt some pony get on the bed at the stirrups. She then felt the tentacle prod her entrance again before slamming right in. The stallion jilted with part of his tentacle dick inside of the womb. The tentacle them blocked off the cervix creating a plug. Redheart felt the stallions testes bulging guessing each of them to be the size of an apple and they felt full. She then felt a spurt of warm liquid in her womb then the floodgates opened up. Her womb started to fill up while the testes were shrinking. After a minute or two the stream stopped. Red had felt her belly expand some due to the amount of semen. She felt the tentacle in her slowly pullout but not before closing up her cervix completely not letting out a single drop. Reds heat was gone. The stallion walked to the door but didn't release her until he was out the door and then closed it behind him. He then left the hospital and went deep into the Everfree forest never to be seen again. Red was left in an awkward position. She got her hooves out of the stirrups after about twenty minutes of calming down. When she got on her hooves Red almost toppled over from the wait of the seed sloshing around inside her. This turned her on majorly. Red went to the bathroom in the room and looked in the mirror. She now looked ready to drop triplets. Her belly had rounded out quite nicely. She left the room and made her way to the room she had left the ultrasound machine in. She got the machine taking it back to the maternity ward. Once she was in a room she started up the machine and put the goo on her belly. She waited for the picture to pop up on the screen and when it did all she could see were eggs. All of a sudden she heard cracking coming from her belly and looked at the screen only to see the eggs were hatching. She just stared at the screen seeing 25 life forms hatching inside of her. Then all the new hatchlings all went to her cervix where they all somehow got past it. Red immediately grabbed a bed pan and put under her entrance. She caught all of the hatchlings in the bed pan. After that she put a covering over the pan to keep them from escaping. She looked at her belly and Red saw she looked overdue with one now. She could feel the semen in her womb sloshing around. She got to her hooves the cum sloshing around in her womb every time she moved. She grabbed the pan with the creatures and released them outside. She then went to a clean room in the maternity ward and got in the bed for a well deserved sleep. Red woke up a couple hours later. She got up and noticed something wrong. She didn't fill any sloshing in her womb. She suddenly felt a kick from within her womb. She then felt another kick after another. She grabbed onto the bed to keep from falling over. After 30 seconds the kicking stopped. Red stood there breathing heavily. She made her way to the bathroom and looked in the mirror immediately noting her belly was than when she went to sleep. Her popped out belly button was almost touching the floor by a few centimeters space between it and the floor. Red made her way to an ultrasound machine to see what was in her. She made out five fetuses in her womb fully grown. At that moment all of them chose to start kicking and moving. This went on for a minute or so. Red then decided that she would need to go somewhere no pony would know her. She got up and went to the front desk where a train schedule was at. There was a train leaving for Las Pegasus at midnight tonight. She packed all her belongings and wrote a note saying she wouldn't be back for awhile. She then tried to clean up the hospital the best she could with her belly and very active children. She knew her uterus would most likely be bruised from all the kicking. Once it was 11:45 pm Red got her belongings and tried to hurry to the train station with her belly. She made it right on time. Once she found a seat she payed down and fell asleep. She awoke an hour later to the train coming to sudden stop. She looked out the window and saw sheep were blocking the way. She wanted to get to Las Pegasus by sunrise so she grabbed her stuff and got off the train to start the trek to Las Pegasus. She had been walking for hours when her children decided to have a kicking contest in her womb it seemed. Red gritted her teeth while still moving along. Red made it to Las Pegasus by daylight. She found a hotel and checked in to it. She then went to her room and layed down falling fast asleep. She awoke a couple hours later to her children kicking. After her children went back to sleep she got up thought about what she was going to do today. She chose to go to a museum. She went to an artifact museum. She was in the teleportation area by herself when her babies got active again. She leaned against the rope but that was a bad idea. The rope fell with her and she fell into a mirror that was actually a teleporter. She woke up a couple hours later. When she looked at her hooves she saw hands instead. She started hyperventilating when her kids chose to all kick at the same time and hard. Red got knocked forward by the kick. Red finally calmed down and tried to get to her feet. She looked at her surroundings. She seemed to be in an old mansion. She got used to waddling in this form. She came across a room that looked like a bedroom. She entered it and found a queen sized bed a decent sized closet with a couple of clothes in it. She saw she was naked and seeing how it looks like nobodies lived here for a while she took a one piece swimsuit which looked to be the easiest to get on. She got it on and looked at herself in the mirror and actually thought she looked sexier like this.
