Maria, a 19-year-old college student, was alone in her room, where she chose what outfit she would wear to go out with her friends that night. Besides her, her younger brother was in his room playing video games, and her parents were in front of the neighbor's house talking to them. She also has an older sister, who has already married and no longer lives with them.
She had just changed into a blue tank top and a white skirt and was considering in the mirror whether to go out in those clothes or change again when she felt her clothes begin to loosen. She tried trying to straighten her clothes once and immediately noticed that her clothes were too big for her, she found this strange and thought she had stretched somehow but the change of size difference continued. Mary then that her shoes were also loosening and she ended up losing her balance, falling down sitting on her bed. When that happened she noticed that her bed also seemed to be getting bigger and looking around she realized that it wasn't the things that were growing, but she was the one shrinking.
While she was shrinking Mary felt something stirring inside her belly, along with the feeling that her clit seemed to be getting bigger, so she took her skirt and panties off, which made it easy for her to see that her clit was prostrating slightly forward and was getting longer and longer. Soon Mary was the size of a toddler, their clothes so loose they no longer held onto her body, and her clit had stopped stretching when it reached an inch and a half, and then was almost covered in fur when it became a miniature cock. It was then that she felt pressure inside her vagina and, shrinking to the size of a baby, she crawled out of her clothes and arched to look between her legs, only to see her vagina close and disappear completely, forming an empty ballsack in place. Then what was moving in her belly, which were her ovaries being converted to testicles, descended one after the other and deposited themselves in their new home.
"What the hell happened to me? Why did I shrink? And why did I become a dickgirl? This cannot be real, it must be a dream." Mary said when her female reproductive system has just been completely replaced by a male one, by this point she has stopped shrinking. She first eyed her new cock more closely, which even though it was 1.5 inches long was still relatively large for her new size. She then stood on her bed and analyzed her size, coming to the conclusion that she shouldn't be more than 6 inches tall now. She pinched herself and with the pain she felt she was sure it was all real.
Mary, confirming that besides her shrinking and having a dick hanging between her legs now and nothing else had changed in her, decided to take action but for that she needed clothes that fit her now. She remembered some dolls from when she was a child and that luckily she hadn't thrown them away, but they were kept in the attic of the house and she wouldn't be able to get there without help now. She climbed out of bed and climbed down on the blanket, then knocked on her bedroom door hoping someone would hear and open it for her. Looking for a way out, she searched among her belongings for something that could help her and came up with the idea of using her bra.
After a few tries Mary finally managed to get her bra strap to reach and used it to pull the handle, thus opening her bedroom door. She left her room looking for help, but she found it strange to walk with a cock hanging between her legs, which unintentionally excited her and made her have an erection. She didn't want to be seen with her cock hard, so she took a detour and went to the bathroom, where the door was always open while no one was using it, and jacked off until she came down the drain. If she was still her normal size the amount of her cum would be far more than any man could produce, yet she was sure she'd sent at least twice as much down the drain.
Once relieved Mary went to her brother's room, which was the closest and he used to leave it ajar when he played video games. She went in but didn't find him there, but the video game was on and the controller was on the floor next to his clothes huddled on the floor. She noticed there was something moving under her brother's clothes, so she walked over and tossed them aside, only to find another dickgirl, one as small as her, who was jacking off.
The dickgirl took a huge fright to be discovered and tried to hide what she was doing, but she was already at her limit and came at the same time, forcing Mary to jump out of the way to avoid being hit by her cum. "I'm sorry I shouldn't.... Mary, is that you? Did you shrink too?" she said
"Yeah, I got small too. But you...you are Matthew, aren't you? You not only shrank, you became a girl too." Mary said to her brother, who was more her sister now.
"I know. This is weird, why did this happen to us?" Matthew said and, as if to answer the question, the stopped game on TV was replaced by three women in a setting totally unknown to the brothers, which looked like something out of a sci-fi movie. The three women wore clothes of a material that resembled a bit of latex, being so tight on their bodies that they technically didn't hide anything. The woman in the middle was sitting on some kind of throne and wearing golden clothes while the other two were standing on either side of her, each in emerald green clothes with silver designs. Another thing that caught her attention was their eyes, which had no iris and were entirely blue, their lips were also as blue as their eyes, and that their clothes had a form outlined in their crotch that made it clear that each of them had a really big dick and balls.
"Earthlings, my name is Longstaff and I am the queen of the planet Futaria. This communication is being broadcast to your entire planet with simultaneous translation so that all of you can understand everything that is said here. You must be finding it strange that you've gotten smaller, as well as a gender change that you've gone through. I inform you that we de Futaria are responsible for this. We took control of your planet and you are now all our little toys now just like them." the woman in the golden clothes said, whose tongue was also blue
One of the women next to the alien queen took a box behind the throne and opened it, she and her companion put their hands inside the box and each pulled a little person out of it, both dickgirls. They both ran a finger over the bulge in their clothes, which opened at their touch as if they were being cut, releasing their hard cocks. Their dicks were 9 or 10 inches long and looked perfectly human, except their tips were blue instead of pink. Queen Longstaff repeated what her subordinates had done, revealing her 13-inch cock to all who watched, so she then stuck both hands in the box and with each grabbed a miniature dickgirl, which they did everything they could to escape her hands.
"Each of you must pay attention to your fellow earthlings as this is the new role we have assigned to you." Longstaff said
The subordinate on her right took the earthen dickgirl she was holding up to her mouth, starting to suck the proportionately tiny dick while stroking her own dick with her other hand. The subordinate on the left lifted her balls starting with her feet, shoved the dickgirl she was carrying in her pussy, ordering her to make her come. The Queen placed one of the earthling dickgirls she was holding upright on her crotch, then placed the other one upright on the shoulders of the first. The pair of earthlings was forced to caress the extraterrestrial queen's cock, which was bigger than the two together.
"This is amazing Mary, there is a real alien invasion going on." Matthew said as she watched the screening of Queen Longstaff and her subordinates on TV.
"This I can see, but why are you so excited? Didn't you realize they want to enslave us as their sex toys?" Mary said
"I know our situation isn't good, but I can't help but be encouraged by the knowledge that aliens actually exist." Mattew said
"What the fuck. From what she said, everyone in the world has been changed just like us, so our parents and everyone they meet must be in the same situation as us. I simply refuse to be used as a toy by these aliens." Mary said
At this moment Queen Longstaff came, firing a pink cum from the tip of her dick, which her subordinates did too right away.
"As you can see this is your destiny. My Futarian subjects have already descended to your planet, where we will live until we need to look for new toys. They are authorized to enter anywhere and make use of any earthlings they encounter. As we don't want you to have to take care of children and that's why we guarantee that none of you have a female reproductive system, as well as increasing your libido so that you can get in the mood more easily. Feel honored to become our toys." Queen Longstaff said and ended the broadcast, thus just having the screen fo game back on the TV.
