Dexter swiped through the articles on his tablet. Nothing but articles and interviews of Mandark in all the major science magazines. Mandark had sold out and gotten some big government contracts shortly after finishing high school. Being a perfectionist, Dexter could almost never mark a project as "complete" and ready for patenting. Despite being twice the inventor Mandark ever was, he'd never sold an invention. Dexter set the tablet down and laid back on the couch, Mandark's flamboyant success gave him indigestion.

The sound of the vacuum cleaner thrumming to life could be heard from the hallway. Dexter's mom made her way into the living room, pushing the vacuum back and forth in a familiar pattern. Probably humming to herself, not that it could be heard. Dexter didn't pay much attention to her until she began vacuuming under the chairs on the other side of the room. As she bent over her green yoga pants were stretched to the max over her gigantic ass. Her exaggerated pear shape holding true over the years. A fairly narrow waist flared into a pair of extremely wide hips separated by delicious love handles. Her pants were so tight that he could see the dimples of cellulite in her rear.

He knew he shouldn't stare at his mom, but he just couldn't help himself. An unfortunate boner began to rear its untimely head. He covered it with his tablet and admired the magnificent globes of his mother's butt for a moment longer. When she moved on to the next room he got up and went to his lab. He needed something to take his mind off that perfect ass.

"Computer, run the roulette simulation on all unfinished projects." He commanded once he was at his work station.

"All unfinished projects?" the computer confirmed.

"That is what I said."

"Running roulette on 743 'unfinished' projects. Selected: Spy-Fly 94% completion."

"That will do computer." A drone soon brought him an anti-gravity cart to his main working area. Various mechanical components were stored inside small drawers on the cart and a magnifying glass was mounted to the frame. Several versions of the Fly-Spy were in various packages on the workstation, Marks 1-6. He grabbed his Augmented Reality gloves and switched his glasses to AR. Several machine arms equipped with detail tools wheeled themselves over to the cart. He spent an hour tinkering with the design, rewriting code, and tweaking the wiring. The arms flew into motion making his changes. As they finished fitting the components together, he rendered a new version of the prototype to go to his fabricators to be printed. He decided to fire up the retrofit and take it for a spin.

His glasses now displayed a point of view perspective from the micro-camera on the tiny drone. His left-hand glove now controlled the drone. He set it to a point and click mode where it scanned its surroundings and flew where he wanted it to go. "Let's go outside and check wind stability," He said to no one in particular. The drone flew out a window and he got a Birdseye view of his house. The drone tagged several features it noted and after taking a thermal reading, outlined 4 life forms. Himself, his mom, the monkey he had in his lab, and his sister who, apparently, was still asleep this morning.

The camera held completely still up to a 19-mph wind velocity where an annoying quiver set in. The drone tagged increased heat and humidity coming from somewhere in the house. Instinctively Dexter said, "let's check moisture resistance." The drone zoomed through an exterior vent and automated its flight until it reached the master bathroom. It mounted itself to the upper corner of the shower. He was so consumed with the project, it hadn't dawned on Dexter where his fly would be going, but suddenly he became acutely aware of his mother's naked body as she slid the shower door open and stepped inside.

Her pale skin was marvelous as the water poured down on her. Dexter didn't notice his draw drop as she lathered up her breasts which were plump but didn't seem to sag despite her middle age. Her stomach only seemed to hold a tiny portion of her body fat, that was all in her ass. She soaped up her backside and turned around to wash it off in the pouring water. She bent over and caressed her butt as the water trickled down, giving Dexter quite the sight.

Dammit he couldn't help himself, he removed his right glove and began stroking himself as his mom rubbed herself down. He was not expecting what he saw next. With her back to the camera she coated her finger in some sort of lubricant and began fingering her ass right in front of his Spy-Fly. She let out a low moan and began to flick her clit with her other hand. His mom continued to finger fuck herself for a few minutes before she stopped and then reached an arm outside the shower to grab something out of sight. She produced a large purple dildo complete with a pair of balls and a suction cup on the back end. The Spy-Fly measured the dong at 9 inches from base to tip. Lining it up with her pussy, Dexter's Mom mounted the dildo to the left side of the tile shower from his point of view. Holding on to the outer wall of the shower she eased herself back onto the toy until her massive ass came into contact with the cold tile. She shivered a bit, in part from the tile and in part from the thick member filling her pussy.

She pushed herself another 3-4 inches until she reached the base, her massive glutes squishing up against the wall. She grinded her butt back and forth a bit as she rubbed her clit, building up to an orgasm. She rode the purple dildo, increasing momentum as she pounded her backside against the wall smacking loudly. Her free hand was braced against the opposite wall and she used it to push herself back with more force. She bit her lower lip and growled with pleasure as she furiously fingered her clit. She was close.

Dexter could hear everything over the microphone he had installed on this edition of the Spy-Fly. Her eyes closed, Mom was envisioning some fantasy as she pleasured herself on the wall mounted cock. "I love your huge dick baby, oh god…It's been so long, my husband won't touch me anymore. He won't come out and say it, but my bottom is just too fat for him. His penis can barely reach my pussy it's so huge. Oh. Oooooh!" she stopped talking for a moment and just moaned. "I know he's sleeping with that skinny babysitter. She doesn't come around anymore, but I know he is." Her breathing was labored and heavy and her nipples were erect. She fucked the dildo to the hilt a few dozen more times before her knees began shaking and with only the faintest restraint in her volume resumed her fantasy. Her ass rippled tremendously with every stroke. Bouncing off the wall like Jell-O. "Oh, fuck me. Fuck this big bum, make me cum on your cock. Make me a cheating housewife. Cuck my two-timing husband and his little dick. Oh fuck, oh fuck oh FUCK!" Dexter's Mom squished her butt against the wall and trembled all over for several moments. Finally, she collapsed to the floor of the large shower, the water pouring over her nude form. The large purple dildo popped off the wall, bounced off the soap ledge and came to rest on her face.

Dexter wiped the sweat from his brow, having long since came all over the floor of his lab. A robot already cleaned up the mess. He saved the recording in an encrypted folder for later use…lots and lots of use. When his breathing was finally under control he said, "Computer, process flight data from the Spy-Fly and mark the project at…99% complete…we may…need another test drive with our final prototype."
