Excerpt from the Chronovac Owner's Manual - [I. The Chronovac (Version 1.0 and beyond) is meant to be handled with care, as transmogrification is dangerous and, when used incorrectly, can cause severe, or even permanent damage to oneself, others, and/or property of the previous parties. It is paramount that if you are to use the Chronovac (Version 1.0 and beyond), you are to express extreme care.]
Of course, Jeff couldn't have known, as he'd only skimmed through the Owner's Manual, what kinds of damage the Chronovac could cause. After doing the dishes, he was about to go back upstairs when an urge came over him. Sitting down on the living room couch, he turned on the TV and sat back. He felt an odd itch in his crotch, but he didn't have time to dwell on it, as Jeff's mom had come down the stairs. Absentmindedly, she walked in front of Jeff and sat directly on top of him, everything from Jeff's hips down disappearing underneath mountains of flesh only just smaller than his head.
Jeff looked up at his mom, both confused and slightly scared, but before he could say anything, he felt her Hello Kitty yoga pants and panties began to pull themselves off her legs, his own pants and underwear following suit. As the waistband of his underwear slid across his shaft, it revealed the source of the itching: his now massive schlong and pair of balls between Jeff's legs. Jeff blinked in disbelief, his cheeks turning a deep red from both shock and arousal. He was unable to stop himself from growing stiff, his cock slowly pushing up against his mom's ass. As pressure mounted against the ass cheek, it gave, and left the tip be wrapped completely in its soft fluff. Then, with a light twitch, the rod slid up between the two behemoths, most of it being fully encapsulated by the two mountains of fluff.
Jeff's shock was soon broken when he felt someone kiss his tip. From between the cheeks, she opened her mouth and gave as good a french kiss as someone without a tongue could give. Suddenly, the ass began to move. Spreading itself, it slowly led her further onto his dick. The inside of her mouth was as soft as the outside, but much tighter. With each pulse, more and more of the tip entered, the walls trying and failing not to be pushed aside by the his head. She continued pulsing over him, until a quiet pop escaped the valley. She had managed to wrapped her lips fully around his head. For a while, she sat here, content with massaging him from every angle.
Jeff gently rubbed his mom's cheeks as she happily sucked on her lollipop, moaning lightly as a wave of pre came filled her mouth. She paused her massage momentarily as she tasted it. Quickly swallowing, she then began to slowly make her advance further down his shaft. With each pulse down, her mouth and throat opened wider, lustfully squeezing all that entered. The cheeks spread themselves to allow her to swallow more and more of his delicious cock. As she reached the base of Jeff's dick, he found he couldn't hold it any longer and gave her what she wanted: his creamy filling. Not wanting to waste any of her well-earned reward, she gulped it down, making sure not to let a drop escape her musky maw. His mother, meanwhile, was still watching TV, as if nothing had happened.
