Paul pulled out his dick to relieve himself while he decided what to do next. Yes, it felt good to be so horny. Yes, the plant smelled great, but he saw what was going on and it was making him mad. Roughly, he shoved his hardon back into his pants and grabbed the foil. "I am not going to be the plaything of this... this... Drug!" he said, a lot louder than he expected to, crumpling the foil into a ball.
He almost threw it away, but then he realized that was not enough. He could still smell its sickly sweet aroma wafting through his room, and he was not going to try sleeping with THAT. He noisily pounded out of his room and down to the living room, thrusting the crushed plants out of their foil and into the fireplace.
Bryan peeked his head out of his room to see what was causing the commotion, and looked down the stairs to see his father rummaging around at the fireplace. He couldn't hear what dad was saying, but he didn't seem happy.
In a moment, Paul had thrown in some newspaper and lighted a fire. He sat back on his haunches, feeling satisfied that he had bested this wickedness. He wanted to watch it burn, to make sure that none was left in his house, so he stayed close and kept the glass door to the fireplace open.
As the newsprint burned down, the plant began to catch fire, hissing and popping as the moisture vaporized. It let off a very different smoke, very thick and white, almost opaque and with a strong aroma. It was so strong that Paul stood up and took a step backwards, but the scent was in his nose now and it filled his head. Instantly, he felt his rock hard boner throbbing for his attention.
Suddenly dizzy, he put one hand on the mantle to steady himself while he rubbed his crotch with the other. The mantle felt like it was slipping away, and Paul knew in an instant that he was shrinking again. He gurgled incoherently, at once furious at losing this round with the plant, and secretly pleased that he had. As his pants loosened around his waist, he shoved his free hand in to squeeze his dick.
It throbbed thickly in response. He loved his dick. It was so big. He looked down at it. It was so big! It was TOO big, in fact. The rest of his body was shrinking, but his dick hadn't shortened at all. It stretched easily, hungrilly up towards his face as it seemed to grow with each passing heartbeat.
