Do you even have to ask? [futa]

Natalia had no martial arts training, but she’d done lots of tai-bo as well as boxing themed workouts. She was young, fit, and thanks to the nanites, could bench press three times her own weight in the gym. She had this. She did a few high-kicks, and threw a few quick jabs before telling Helen,“You’re going down momma-bear!”

Helen on the other hand didn’t belong to a gym, or do group exercises modeled after martial arts. She just spent lots of time on job sites hauling material and arguing with men twice her size. She’s also been involved in dozens of bar-room brawls. And she had learned the secret of winning those was to let the other party talk, but once you decided to take action, to just do it.

Natalia was still posturing when without warning Helen dove forward and tackled her around the waist, driving her back against the heavy solid oak desk and overturning her onto it. Her head came down with a loud thunk onto the thick top causing her eyes to water in pain and disorienting her.

While Natalia was fighting to regain her senses Helen was looking at the top of the desk with interest. “I thought this thing looked too clean and uncluttered to be a real desk,” She said as she pressed down on a small square inlay and it flipped up to reveal a ringbolt underneath.

Natalia took a swing at Helen that the milf ducked away from and then swatted the younger girl, hard, in the solar plexus. Natalia woofed, but did not have the air driven from her lungs, or fight to draw air into her lungs with a temporarily paralyzed diaphragm.

“That’s right. Modified internals. Have to look into that later,” Helen mused as she grabbed Natalia by the hair and slammed the back of her head back down on the desktop as hard as she could.

“Stop that!” Natalia protested as tears streamed out of her eyes, which were still showing bruising from earlier. The fact she did not have a pair of livid black eyes was due solely to the nanites in her body fixing the subdural bleeding before it could cause more than slightly visible bruising.

The sheltered girl displayed her naivety by rubbing her hurts and wiping the tears from her eyes instead of scrambling like mad to present a moving target while she recovered enough of her vision to defend herself effectively. First rule in a bar fight, do not stop moving. When knocked down, roll, and keep rolling.

Helen did not let the time go to waste. In ten seconds she had shucked her pants and doffed her flannel shirt, leaving her fully naked. She had a very good body for a woman her age. Her c-cup breasts sagged, but not nearly as much as would have been expected. Her stomach was flat, and her plump, bare, pubic mound would not have looked out of place on an eighteen year old virgin, except for one thing. She looked like she had a sex toy inserted in her vagina, backwards. About two inches of a thick pinkish shaft topped with a bulbous spade shaped tip projected out of her cunt. It looked freaky as hell. What it did not look like was thirteen inches long.

Helen stepped up to the end of the desk, standing behind a groggy Natalia who was still trying to blink the tears out of her eyes. She reached up and once again used the younger girl's hair to good effect to pull Natalia’s head back down against the oak top. The thunk was not as loud, but still audible.

The older woman looked down into Natalia’s tear filled eyes and said, “You lose.” She leaned forward and brought both hands down hard onto the big girl’s firm, but doughy breasts with two loud slaps that echoed off the paneling.

“Ahhhhhh!” Natalia cried out, but Helen wasn't done. She clenched her fingers and dug them deep into the other girl’s tender tits and with a grunt hauled her down the desk toward herself,

“Eeeeeiiie, glurk,” Natalia squealed, right up until her head fell off the edge of the desk and Helen hunched her hips forward and drove the short stub of her new tool into the other girl’s open mouth.

“Ohh, yeah! I can see why guy’s love this!” Helen hissed in pleasure as she felt Natalia’s mouth envelope her flesh. She leaned in hard and trapped Natalia’s head between her thighs and side of the desk. The brunette reached out to try and push Helen away but the smaller woman caught Natalia’s slender wrists in her work-hardened hands and forced them down against the desk. Then she just let Natalia’s mouth do the rest.

Helen had only discovered the change to herself when her new tool had slipped out of her body when she was masturbaiting. Since that time she had found that simply being aroused would cause it to swell inside her sheath and cause the tip to emerge, but to get the whole thing to stick its neck out you had to directly stimulate the head, and Natalia’s tongue was doing a wonderful job of that as she tried to push Helen’s tool out of her mouth.

“Ohhhhhhhh, yeaaaahhhhh!” Helen sighed as she felt her faux cock swell inside her cunt, and begin to slide forward as the new set of muscles she had never possessed before forced it out of its home between her legs.

“Guk, guk, guk!” Natalia gagged as Helen’s cock swelled inside her mouth, forcing her jaws to spread even as the bulbous tip pushed into the top of her throat. A ring of saliva formed around the circumference of the older woman’s faux dick as Natalia choked on it. Her feet began to drum on the desktop as she thrashed, but with her hands and head held firmly in place there was little she could do to prevent Helen from raping her throat. Though the way she bucked her body did cause her large breasts to flop about in a visually stimulating fashion.

Helen had never felt so free. In the past she’d always repressed her darker urges. Like the urge to slice off her lying sack-of-shit husband’s dick, or to punch the president of the PTA in the throat when she suggested that maybe John would do better in a special school. Now, however, her new role pretty much mandated she let out her inner bitch to keep John’s harem in line. Or so she chose to interpret the role. The way the little cat-girl was reacting to her behavior seemed to indicate Helen was on the right track, anyway. Therefore she had zero inclination of taking it easy on the big-titted bitch who had disrespected her, and who had delusions of treating John like a trained monkey who would dance on her command. The slut needed to learn who was in charge, and in such a way that she would never dream of challenging Helen’s authority again.

“Huk, huk, huk,” Natalia gagged as Helen’s faux cock pushed into her throat, forcing her slender swan like neck to bulge obscenely as the thick cylindrical shaft traveled down it. It was quite a sight to see, and the vibrations that resulted from Natalia’s muffled screams and gagging felt wonderful. The mental satisfaction of forcing herself on the girl was the icing on Helen’s enjoyment.

“Huurggghhhhh, ukh,” Natalia let out one last audible objection, before going silent as Helen’s dick blocked off her airway. John’s mother rather missed the sound effects, but the feel of the girl’s throat spasming around her cock more than made up for it.

“How long can she hold her breath, do you reckon?” Helen asked loudly enough so that Natalia would be sure to hear. She clenched her ass and tried to encourage her inner muscles to push more of her dick into Natalia against the resistance of her throat.

M’Ress considered the question and then said, “At least ten minutes I would think. Natalia’s respiratory system is more efficient than normal humans thanks to the nanites. You don’t have to worry about suffocating her. The nanites can scavenge air through your skin if needed.”

“I’m not sure if I’m happy or sad about that,’ Helen remarked. “I think I’d rather enjoy choking the little bitch out, but John would likely be unhappy if I did.”

By this time Helen’s dick had extended to its maximum length and a full thirteen inches was buried inside Natalia. With a groan of appreciation Helen slowly pulled her hips back, drawing inch after inch of slime covered shaft from between Natalia’s lips. The slimy mixture ran down the girl’s face and joined with her tears. With a grunt, Helen clenched her firm ass and rammed herself back down her victim’s gullet, causing her to thrash even harder, which did wonderful things to her jello mould tits. The wobbled in a most enticing way.

The sound of Helen’s thighs smacking against Natalia’s face, as well as the thunk, thunk, thunk, sound of the back of her head hitting the side of the desk, filled the room. In the end the horny milf could not restrain herself, not that she knew how to do so, and she felt an ache deep in belly as her transformed ovaries swelled right before they started to pulse and force a thick ejaculate down her long shaft and out the end.

Natalia was unable to make any sound, but the drumming of her feet on the desktop indicated she was not enjoying the process of having her stomach pumped, in reverse. The wonderful sensation, for Helen, seemed to go on and on, and the milf was sure she detected a slight bulge forming in Natalia’s former flat tummy.

But, all good things must eventually come to an end and Helen let out a sigh of satisfaction as her inner organs stopped pulsing and the last of enjaculate flowed into Natalia’s overfilled belly. With a bit of regret she withdrew her cock from her future daughter-in-law’s mouth, one inch at a time. Natalia let out a huge gasp as her airways were unblocked, that turned into a sputtering cough as she cleared her throat of the backwash from Helen’s orgasm. As the tip of the MILFs cock pulled free of her throat it was followed by a gush of come that ran all over the degraded girl’s face, covering her with visual evidence of her humiliating defeat.

“So! Tell me! Who’s the boss?” Helen demanded as she pulled Natalia’s head up by her hair and glared down into her spunk glazed face.

“You are,” Natalia said in a thread thin voice as her aching throat protested.

“That’s what I thought.”

Helen turned to look at M’Ress who was hopping from paw to paw while her tail whipped back and forth behind her. “So, your turn?” Helen asked, rhetorically.
