Her Sister Maggie

Of course John’s first target was his/her… John paused, ‘Ok I’m mostly girl now so probably female usage now… and name? Oh!’ A snap of the finger and John became Jane. Now that was settled her first target was her sister, who was a year older than her. She didn’t even bother putting on clothes as she walked out of her room. She went to her sisters room and saw the door was slightly open, she walked up and peeked through the crack. Her sister Maggie, was sitting on her bed reading something one hand held up the book while the other was at her crotch. Jane opened the door and Maggie lowered the book and sat up alert. She looked at Jane, “Jane what the hell!?” She gasped, “What’re you doing here?” she demanded. Maggie was a good looking girl, short brown hair, stunning brown eyes, decent sized D-cup breasts, and a 20 inch booty. Jane frowned and snapped her fingers instantly Maggie's breasts shot up to J-cup size while her breasts became 40 inches across.

Jane smiled, “I’m feeling a bit horny, and the need to breed… so sis let’s get breeding!” Jane jumped her sister who squeaked, but despite what she had said earlier Jane could smell the wet pussy. “Mmmm someone’s also a little horny Imagining yourself being fucked by me?” Maggie looked away her face bright red. Jane lowered herself down to her sister wet crotch and grabbed the pants pulling them down to reveal her prize. She began to slurp and lick up the juices while probing into her sisters folds. As she did her balls began to swell, a bonus to her if she drank love juices her balls would swell to the needed amount of sperm that the woman wanted to be impregnated with. The stronger the desire the bigger her balls would get, and as an early precaution all women Jane had sex with would be capable of stretching their bodies infintely.

Jane kept licking and drinking till she felt her balls stop growing and she got up and shifted so her balls were in view. “Wow sis you really want babies that badly?” She asked. Jane’s balls had doubled in size becoming as big as a large pumpkin. Maggie blushed and looked away, she then mumbled something. Jane leaned in, “Can’t hear you speak up!” she ordered.

Maggie said, “I wish I was born with your dick…” she said, “It’s not fair you got it from Mom, but I didn’t I wanted to keep the family tradition of being a mass breeder but you got it!” she said.

Jane was surprised as new HIstory began to fill her mind. Her family from her ‘mother’s’ side was a proud breeding futa group which was helpful for foreign nations primarily. Futa’s existed but they made up about 20% of the population now with Women making up 79% and Men down to a measly 1%. Scientists noted that most futa’s were born from a mutant gene in Men that would transfer to their children making them futa. With time futanari began to seed in the mutant gene and with this mutant genome male birth rates were in a steep decline. Futa’s not only were generally larger than men but their sperm was 5 times more productive and potent than males. Also family genetics played a heavy role and some futa families were born with specific traits. Jane’s family was noted for having very large assets and their special growth from ingesting women’s sexual juices.

Typically 8 in 10 children from futa’s were futa, though originally it had been 1 of 10 quite a leap in numbers. So she were part of what they would call the ‘Super Breeders’ family. Her aunt was a futa, as was Jane’s mom and Jane… but Maggie was still a woman. Jane felt bad then and she hugged her sister, “Hey sis.” Jane said, “Is it really so bad about being a woman? It just means you can be an awesome wife one day!” She said, “Me? I’m gonna be breeding bitches day in and day out for pretty much the rest of my life, I won’t have time for a family, getting a wife, having kids I’ll be too damn busy.” Jane pointed out.

Maggie considered that, “When you put it like that… it’s not so bad is it?” she looked down then up at Jane, “But if I could I’d marry you.” she said, and she sat up and kissed Jane. Jane had to admit it felt… good to just kiss. She pressed against Maggie her big breasts meeting Maggie’s equally large bosom. The two laid on the bed kissing and moaning gently. Jane’s dick was throbbing with desire pre-cum spilling out like a fountain mixed with white sperm. They broke and Maggie looked at Jane, “Impregnate me!” she moaned.

Jane was more than happy to oblige and she grabbed her sisters legs pulling them up while leaning back so her dick was in thrusting range. She thrusted her dick in and sunk in 20 of her 28 inch monstrosity in one go. Maggie gave a cry of pain, and Jane felt something warm on her dick, “You’re a virgin?” Jane asked, Maggie nodded through the pain. Jane leaned in and rubbed Maggie’s face gently and affectionately, “Shhh I’ll move when you’re ready.” the two laid there for about a minute before Maggie inhaled.

She looked at Jane, “I’m good.” she said. Jane began to move slowly thrusting in and out slowly to give her sister time to adjust. After a few seconds, Maggie said, “Harder!” and Jane went harder thrusting so hard that her hips slapped against her sister’s big booty. “Oh fuck!” she moaned as Jane pounded her. They kept fucking and changing positions for at least 3 minutes before Jane felt her cock begin to bulge and her balls swell up.

Jane grunted, “Ah fuck I’m almost there!” she hissed. Maggie nodded and her legs closed around her futa sisters butt locking her in. It was approval enough, “Here it comes!” and she slammed it all in and unloaded her dick pumping sperm into her sister. Jane throwing her head back and her hips forward butt clenching with the push while she gritted her teeth in a rough growl. Maggie watched as her belly first shifted up then began to inflate rapidly. Jane came for a full minute and when it was over she fell forward exhausted from her first sexual encounter her sweaty face making contact with the equally bulbous belly, the two laid there panting Maggie unable to see with her belly looking like she had 2 walrus’ inside of her. “Holy shit that was… fucking amazing.” She said, then she turned her head and began to kiss the bulbous, jiggling mass pulling her flaccid dick out and moving down till she got to her sisters face and kissed her. The two tonguing for a while then parting. “You are incredible.” Jane purred.

Maggie blushed, “You too, I’ve seen Mom in action and she’s good but she doesn’t last as long, she fucks like crazy, like, holy shit she broke the bed twice! Shoots more than you but I think if you take that fruit that helps with, like, sperm production and shit you might do it.” Jane blinked.

She was surprised, “Uh… what that exists?” she asked.

Maggie rolled her eyes, “Ok look you might of been gifted with, lke, godly genes but that doesn’t mean you won’t need some help growing sis. I know how to get that shit and plenty others hell I’ll not only make you the biggest but I can get the best bitches for you to filll up with all your hot baby juice!” she said.

Jane could see it, her being 7 feet tall a monstrous cock erect and throbbing and balls bigger than cars bloated with seed while all around her girls and women lied about her some bloated other’s fawning over her. But maybe it’d be best to take it slow and not rush it just enjoy herself with not only her family but the other hot milfs in the neighborhood who would be eager to jump at her...
