Jeff wondered what it might be like to have a household object for a body part. The concept was oddly appealing, but he couldn't think of what to try it with. It was then that he heard his dad shout from downstairs.
"Jeff! Stop jerking off and clean up your room!"
Jeff laughed a bit, knowing he was only joking, but it gave him an idea. He opened his cupboard and pulled out a vacuum cleaner, propping it against the bed as he wriggled down his pants and held his dick in one hand.
Stroking himself slowly to hardness, he clicked the chronivac to execute the body part swap, and immediately felt a shudder run through his groin. As he stroked his shaft, he felt it thickening in his hand, forcing his grip open until he could no longer close his fist around it. Grinning, he continued to stroke as his cock grew longer and longer, his fleshy rod stretching up and flopping over as it grew as long as his arm.
Holding his massive, thick hosepipe of a dick in glee, he shivered as he felt his cocktip opening up, stretching wider as his shaft hollowed out and began to change color. The fleshy softness gave way to the cold hard feeling of plastic as his dick turned grey, his cockhead opening up into a round nozzle as his shaft became a twisty flexible hose.
Finally, he grunted and shuddered as he orgasmed, cum splattering out from his nozzle cock into a dripping pool on the computer table. Looking down, he dropped his dick and allowed it to dangle between his legs, a long grey plastic vacuum nozzle.
Something wasn't quite right, though. Quickly typing more into the chronivac, he set it to execute another change, and stretched his legs as his balls began to swell, hardening as the flesh turned soft and smooth, before slowly becoming clear. Through his transparent scrotum, he could see his testicles fuse and transform into machinery as his balls transformed into the round plastic shape of a vacuum compartment.
He jumped suddenly as he felt a sharp pain in his rear, and quickly leaped to his feet. He felt something pushing down from his tailbone, growing long and swinging from his rear. Twisting around, he saw a plug dangling from his butt by a long grey cord, and found he would twist and move it like a tail.
Looking over to where his vacuum had been, he saw that now was sitting his former cock and balls, resting disembodied but looking just the same as they always had.
Curiously, Jeff picked up his old genitals and tried stroking them. They were warm and soft, but they gave him none of the pleasure to touch as they used to. Reaching down to pat his long dangling hosepipe, however, made him shudder with arousal.
He looked at the dusty floor, and hefted his nozzle dick in his hand, wondering whether it was worth a shot. Shrugging he walked over to a plug socket, and twisting his "tail", slowly slotted it into the wall.
He immediately jumped and moaned, electric orgasmic pleasure crackling through his body from his rear. A roar immediately emitted from his cock as the mechanism in his balls began to spin furiously, sucking air into his dick.
Jeff gasped and twisted in uncontrollable orgasm, until finally he managed to wrench his tail free, the roaring from his dick immediately stopping as he collapsed, panting and gasping. It seemed that when he was plugged in, the pleasure was so great that he could not think or control himself to actually clean anything up. Like a real vacuum cleaner, he needed another person to use him in order to clean anything.
