Scott peeked out from the blankets as his roommate left the room. Don thankfully had the presence of mind to not stand in his doorway with the guest. Scott felt his balls, shrunken he knew but they felt the same size as ever. Looking up at the plant by the window, he remembered the spinning, tingling, shrinking sensation that had now left him. It was definitely true that he was no longer shrinking. Nor was he so fucking horny that he could barely see. He sighed. Don said the effects were probably wearing off already, and it seemed that way to Scott too. He sighed, his hairy chest tickled by the blankets.
'Well screw that!' Scott thought, sliding out from under the blankets and quickly stepping over to the plant. He tried to choose a small leaf, but at his diminished stature they all seemed pretty big to him. 'One third,' he thought as he looked at the large desks which now occupied the corners of the room. That would make him a little more than four feet tall. He plucked his chosen leaf. Knocking another third off his height would make him about three feet tall. Pretty small in anyone's book, but still perfectly manageable, especially with Don's help.
He tossed the leaf into his mouth and started chewing as he climbed back under the covers. Its sweet juices sent a tingle down his spine that seemed to go straight into his resting penis. "Oh!" he said out loud. It was like his body was receiving electric shocks, each one jolting his sexual intensity higher and higher. The buzzing was back, and man did it feel great.
