Jeff typed away on the computer screen grinning as he programmed the Chronivac to extend his own dick even longer, aiming for two feet now in length. After entering his options and raising his sensitivity again the machine makes a loud beep as Jeff's eyes roll back into his head as his cock swells and grows even more.
Jeff now pulsing in near orgasm grabs his 2 ft dick with both hands and bends it between his legs. Just touching it makes cum shoot out of him in consistent pulses as he bends his dick towards his ass. He gets up then gets down on his calves, his long member scrapes the floor as he bends it ever closer to his anus. He feels the tip of his penis make contact with his cheeks before plunging his member's tip into his anus Jeff then moans with a slight yelp and loses his balance in his legs, making them give way under him forcing his dick deep into his anal cavity. Jeff then gasps and orgasms almost a liter of cum into his rectum. Jeff lays sits there drooling for a while as the pulses die down, as his own juice leaks from his anus.
Jeff gets a clear moment to think now but can tell another orgasm is coming. He really likes this, and with an evil grin quickly decides he never wants it to stop. he goes back to his desk chair and sits down, his penis squished between his legs and ass crack immediately goes back into a hard on and sprays more cum into his ass as he sits down on the chair. Jeff can't stand it, he needs even more, and for it never to stop. he quickly types away at the Cronivac to shove his dick all the way into his ass and seal him up for good. Making his own dick permanently be stuck in his ass so he can butt fuck himself forever. With a few extra keystrokes and a swift press of the enter key. the machine beeps again and the changes happen.
Jeff takes both his hands and grabs his balls stroking the stalk of his dick as it plunges deeper into him. Jeff lays back in his desk chair barely able to contain his enjoyment as he moans loudly; his dick shooting deep into his rectum. He doesn't notice his balls and shaft sinking into the wedge of his groin between his legs and fusing into his ass. Jeff pulses in orgasm again as his groin goes smooth and his penis fully fuses into the inside of his ass. within moments his anus is completely gone and just a smooth patch of skin remains on his groin with a shallow lump all that remains of his package. Jeff takes both of his hands and rubs the smooth spot on his groin and falls over again in ecstasy as his backside vibrates and throbs in wave after wave of orgasmic delight.
Jeff spends the rest of his night molesting his smoothed parts, orgasmic, pulsing and humping his way into pure bliss until his body tires and falls asleep. Jeff awakens the next day feeling completely fine and already ready for more action, seeing the sun peeking through his window, he quickly snaps back to reality and sees that over 10 hours passed since he plugged his ass with his own dick. He then looks down to see his smooth and barren ken-doll like crotch and questions if what he did was real in disbelief. He takes two fingers and touches his groin before immediately going back into a full blown orgasm again. Once he calms down, he laughs to himself before looking back at his machine again with a devious grin on his face and starts typing away the next change.
