The lift had stopped far down, opening up to an enormous room that no one could predict was this deep. "What in the world?" Jeff asked, looking around after stepping out. Lights from the floor lit up areas of the walls, where news articles could be found pasted together as some kind of memorial. Stepping over to one, Jeff reads the headlines, "Marvelous Milf rescues trapped policemen. Marvelous Milf stops ship from sinking offshore. Marvelous Milf earns key to the city?!" Jeff wasn't quite sure how, but in reality his mother was some kind of superhero known as Marvelous Milf! She was known in their hometown and very liked among older folk. "Why didn't I ever hear rumors about her? Surely a superhero is something younger kids would love to hear." Jeff pondered, before stepping over to a wall of pictures.
"Oh, that's why." He stated, gazing upon the photos taking of his mother on superhero duty. Her outfit was a practical sling bikini, covering barely anything in the back and showing off her large breasts. The bottom was practically wedging into her pussy, and she had an ornate tattoo right above her crotch. Her legs and arms were completely bare, and she adorned platform flip flops on her feet. Her mask was white and covered her whole head, with her hair sticking out the back in a ponytail. Her mouth and nose were uncovered, but for some reason, her lips seemed triple their normal size and covered with a deep red lipstick. "No wonder parents hide Marvelous Milf's existence from their kids, she's a fucking pervert!" Jeff shouted with a laugh, before realizing he was now Marvelous Milf for the time being.
Shuffling further into the back of the room, Jeff comes upon a large terminal system, with screens of news channels and programs. One screen revealed a log Jeff's mother was working on; the document still open with the cursor flashing. "Whoa, she's writing an autobiography." He admired, scrolling down a bit. The second page had what explained away all of this; the origins of his mother's powers, whatever they were. She detailed how she had found a machine, that gave her whatever she would want, though she had self control not to abuse it. She first revealed how she stopped her body from aging any further beyond 34, "That explains why she always looks so young and hot." Jeff noted, reading onward. It was then she gave herself super strength and the ability to fly; pretty standard powers, to be sure. A year later, however, was when she gave herself a brand new power. The ability to make her lips triple in size and blow kisses that can enamor, confuse, or knock unconscious whoever she wished. "Probably good for sucking dick, too." Jeff nodded.
Skimming through the rest of the document, Jeff failed to grasp the similarities between the chronivac and the machine his mother used to gain powers in the first place. But, it did blatantly reveal that this hidden hero cave and costume were thanks to that machine as well. "Well, if I'm a super heroine for now, might as well go out for a test run!" Jeff declared, investigating the cave further until he found a stand containing Marvelous Milf's hero costume. Slipping off his mother's casual clothes, he pulled the tight sling bikini over his mature body. The straps pressed against his E cup tits, and the string rubbed against his labia; completing the ensemble with the platform flip flops and struggling with the mask. "Damn, I feel powerful!" He shouted, grabbing at his revealed breasts and ass. Getting back into the lift, Jeff heads back up into his house, neglecting to have read the most important part of his mother's autobiography.
The last chapter explained she had an arch nemesis, Flaming Fiesta; an equally beautiful latin woman, dressed in flamenco dress, with a black and red luchador mask. Turns out, she had been a rival of Jeff's mother for a long while, an at some point snuck into the milf cave and used the machine to give herself the ability to shoot fireballs from her hands. Marvelous Milf stopped her before she gave herself any more powers and the two fought. Flaming Fiesta ended up burning the machine to a crisp, and stealing the smoldering remains. Thankfully, it turns out the damage made it completely unusable ever again, so Flaming Fiesta went into hiding in her civilian alter ego ever since. Marvelous Milf then followed suit, to just live out her days as a mother and wife; and that was five years ago. Though, who knows what will happen now that Marvelous Milf is coming out of hiding for the first time in years.
