Paul was not a smoker. He had given it up when he was in his 20s, what with all the "smoke and you will die" campaigns that the government was running. He did come from a family of smokers, though, and he still had his grandpa's pipe... a family heirloom of sorts. While this plant was too wet to be a good smoke, it was worth a try...
Stealing quietly down stairs, Paul went into the basement and rummaged around for the box. After a few tense minutes, he found it and took out the white, ivory pipe. It was a real beauty, and he thought for a moment of keeping it out, but he'd hate for his kids to lose it or break it or something. Passing through the living room, he swiped some matches and made his way back to his bedroom.
He took his clothes off and sat on the bed, his tools arrayed before him. Careful pinching off two of the leaves, he filled the bowl and set everything but the pipe and two matches aside. Nothing caught with the first match, but the second was more successful and Paul breathed in a puff of smoke. It had been a long time since he had smoked, and Paul quickly caughed the thick white gas out, his eyes watering.
Before his match went out, Paul took another hit and held it successfully, feeling the inky smoke tingle his insides as it climbed from his neck down to his groin. Even before he let his breath out, he started to feel something. With a long exhalation, Paul blew a rod of smoke out his mouth and nose which quickly dissipated into the room.
Setting his pipe down, he leaned back as he felt his dick go from fully soft to fully hard in only two heartbeats. It felt like someone had literally blown his penis up like it was a balloon, inflating its full eight inches in only two breaths. Paul closed his eyes, cupped his big balls in one hand and wrapped his other hand around his cockhead as the room started to spin.
He felt his butt slip against the sheets, and he knew he must be shrinking. But it also felt like someone was blowing on his dick -- from the inside. It started to expand in his hand, and his balls grew heavier even as they tightened up against his hairy crotch. As he started to stroke his big dick up and down, he knew it was definitely getting bigger.
Opening his eyes, he looked down to see that his proud eight-incher had already climbed its way up to 10. His balls, which he knew were bigger than average, were spilling out of his hand as they swelled also. He started stroking his sex and was pleased to discover that even while his hand seemed smaller in proportion to his rod, it felt a lot better as he stroked.
Paul looked around the room to see that he had already shrunken a substantial amount. He was going down much faster than he had earlier in the afternoon. As his dick passed one foot, he decided to jump out of bed to feel the pull of gravity on his swinging orbs. He was closing in on three feet as he stood beside his bed, releasing his testicles so he could tweak his fur-covered nipples.
His 15-inch dick felt fucking great as he rubbed its tip against the palm of his ever-shrinking hand. He had never really been a "nipple man", but the sparks he was getting off his chest were a welcome addition to his masturbation. 'If only I had someone to penetrate him up the ass right now,' Paul thought, not even noticing his gayness.
Paul sat down, his balls easily filling his lap as his dick stretched up to his pecs. Oh, this was incredible. Paul hugged his cock with both arms as he shrank around it, leaning over to lick the head as it grew. He knew he was getting quite small -- just a little over two feet now -- but the "real world" could be dealt with later... after this upcoming orgasm, for example.
He could feel it coming a long way off. As his dick pulsed, his whole world pulsed. He realized he was probably more sex than man at this point, and that just turned him on all the more as cum started bubbling out of his tip, right in front of his face.
"AAahh..." groaned the little man, shrinking below 16 inches as he writhed in pleasure on the floor. He wasn't a man having an orgasm, he was an orgasm having a man, spurting cum on the floor in a cone-shapped blast. Giant balls pushed Paul's legs aside easily as they crunched up to deliver their payload. Waves of pleasure radiated down Paul's erection and into his body, pushing out every other sensation. He floated blissfully.
After a long time, Paul realized that he was laying on his side, on the floor. His enormous dick had receeded somewhat, still at least partially hard. Just having it attached to him felt absolutely, fucking incredible. Slowly, he sat up. His head was still swimming, but normal consciousness had at least started to return.
