Ty was walking down the street late at night, having stormed from his foster parents house after an argument with them, while he was walking along he was blindsided by an extremely well endowed futanari breeder who then shove his face into a smooth wall pinning him there and tore off his jeans in one strong yank.
Ty knowing what was about to happen, Please don't make me a futa bearer!, She replied, My name is Meredith Greyhound and as I have chosen you to bear my futa babies, your desires no longer matter. Also, when my cock head touches the spot just behind your soon to be formerly puny cock and nutsack, a giant sperm will erupt from the tip of my cock and burrow into the underside of your groin into your lower abdomen giving you a female reproductive system. Ty hearing this began trying to use his powers to stop time and get free, but his power wouldn't heed his call or orders, Sorry baby, I put a collar around your neck that nullifies your abilities, and it will remain there until you have accepted me and the fact I am your dominant mate.
Ty then felt the tip of her cock be pressed to his skin above his nutsack as he had been bent over, and what she had said came true a giant sperm the size of a football, pushed into his crotch like it was an ovum, it burrowed into his lower abdomen and stopped, he heard a wet squelching sound and looked down to see it's tail had fallen off. Then came the burning pain, his organs shifted as his pelvis changed shape, and a full female reproductive system had formed from the giant sperm cell in the 45 seconds of agony.
Meredith then pushed her huge two foot long three inch thick cock into Ty's new pussy to the base breaking his hymen and claiming his virginity, while she remained still to stretch her new submissive out her giant watermelon sized nutsack rested against Ty's kiwi sized nuts, Meredith's right hand caressed Ty's abdomen and her excess virility leaked into Ty's cock and balls, causing them to grow to breeding bull sizes, she then began to thrust into his pussy breeding and making love to him for hours
Ty came from his new pussy seven times and his newly enlarged manhood three times emitting orca level ejaculations. Meredith then hilted inside Ty penetrating his cervix and entering his womb. Then lava hot deluge that erupted directly in Ty's womb swelled and bloated his belly to the size of a car, by this point Ty had already ovulated four times and knew he had been impregnated.
Ty asked his dominant futanari mate, Will I still be able to get females pregnant?, Yes you will Ty, but it will be for tomorrow, and you will start with your step mother.
For now though you will climb into my car and we will be living in my mansion together, I own the greyhound bus service and am rich, I also give my driver's a rather sizeable paycheck. You will be sleeping in the master bedroom with me, I also have a military contract for producing huge heavily armed and armored robotic war dogs that can be repaired and replaced instead of using flesh and blood dogs that take too much time to breed raise and train. I have already had four of them produced and retrofitted to be your guard dogs, they will follow you around until you've given birth. My status as married to you will be announced tomorrow. The robotic guard dogs are still military grade, and cannot be snuck up upon, they cannot be fooled so don't try running away, I will always find you.
As she drove them home she added, Also, you won't be able to commit suicide or abort your pregnancy due to the collars control over your nervous system. Ty began to cry and sob softly is resignation, Meredith heard him crying and said, Don't be sad love, you will learn to love me. Also, I have a surprise for you I kinda already had your foster family brought to our home, your foster mother is now your birth Mom and her husband is your birth Dad.
They arrived home, and Ty saw his mother in a special breeding and impregnation stockade.
Ty got a hard on and approached his mother's huge bubble butt spreading both cheeks open and pushed his new breeder cock into her pussy through her cervix and into her womb, Ty said oh Mom!, your pussy is so tight! Ty spent the next hour pounding his Mother's huge bubble butt until he came announcing it loudly, OH MOM! I'M CUMMING!, BLORSH! BLORSH! BLORSH! SPLURT! SPLURT! SPLURT! BLORT! BLORT! BLORT! Five hours of unspent cum blasted from the tip of Ty's cock into his mother's baby bakery bloating and inflating her belly obscenely to the point it was visibly touching the floor. Mmmm, I think you look much better with a baby in your oven mom, oh I almost forgot your former husband and son, now soon to be futa daughters were watching me breed you. Ty kisses her on the lips, and says thanks Meredith I've been wanting to do that since she started being such a BITCH. Meredith giggles and replies, Your welcome honey, I saw what they were doing to you, and decided I had to get you out of their custody, but the only way to do so was through the futanari's right of mate choosing, and that's why I practically forced myself and my will on you, why don't you go get changed into a Christmasy maternity nightgown, oh and your breasts will grow in while you sleep since your conscious mind is preventing them from growing in. Oh, and I've already had the Christmas decorations put up for the year before I went out, anyway looks like that collar fell off while you were fucking your mom pregnant.
Ty took advantage of this and using his newly freed pent up powers practically screamed, I WISH THIS WAS ALL A HORRIBLE DISGUSTING NIGHTMARE AND THAT MARK AND JANE HAVE ALWAYS BEEN MY BLOOD PARENTS AND LOVE ME UNCONDITIONALLY!
Meredith ran down from the bedroom having heard Ty scream these words yelling, What have you done you stupid bitch!? But her rage and indignation we're rendered pointless as a bright golden flash enveloped the world and everything, was changed.
Ten months later......
Ty woke up in bed with a gasp, shivering in fear at the horrid nightmare, and felt something different about himself, first his chest had what appeared to be hyper double D cup breasts, which when she touched them she moaned and got wet in her pussy immediately, she still had her cock from when she was male before going through her herm puberty, though it was much longer and thicker than her male forms cock, her testicles however were a sight to behold, giant and pendulous watermelon sized testicles hung sagging slightly from their weight though her scrotum having been remade to be able to handle them her mother/current mate rushed in having heard the gasp, and though seven months pregnant with twelve of Tyra's babies she knelt beside her mate and lover and said, Here baby, drink the milk of my hyper H cup breasts and forget your worries, your kidnapper and rapist Meredith Greyhound will never bother you again. As you know, she was executed by military firing squad for her crimes ten months ago and, your body adapted the extra DNA forced on you by that retched woman and forced you to go through that awful agony of a second forced puberty to not die from the excess, but Martha went into an adult sized artificial womb to becomes your other mate though with a cock and basketball sized balls.
Tyra latched on and did nothing but, GULP! GUGLURP! GUGLURP! GUBLORP! GUBLORP! GLORP! GULP! GULP! POP!, Tyra then nibbles on Jane's nipple causing her to moan loudly and cum from her pussy. Tyra pulls pregnant Jane into bed and rests her huge cock against Jane's huge sexy supermodel bubble butt, and her giant hyper double D cup breasts against her back wrapping both hands around Jane's pregnant baby bump rubbing it lovingly like the best daddy in the world. Mmmm, Tyra baby, that feels so good and the kids are falling asleep rapidly, I can feel their kicks getting weaker, meaning their less and less active.
Tyra says sleep well my love, she kisses Jane's neck and falls asleep herself holding Jane in her arms.
