It wasn't long until the doorbell rang. Dylan ordered Evan to answer it and he did so happily. There were two teenagers at the door, Sam and Austin. Evan recognized them from school's football team, but they were never close friends. They looked up a the beast in front of them, shocked at what Evan had become. He was incredible. All 6 feet and 5 inches of the man in front of them was ripped, shredded muscle. Their heads came up just above Evan's hairy pecs. Sam and Austin weren't small by any means, in fact they were quite large for their age which is what made them such gifted football players.
"COME IN" a voice boomed from beyond Evan.
Sam and Austin weren't sure exactly what was going on, but something about that voice was so irresistible they couldn't help but walk passed Evan so find the source of the voice.
They would have been more shocked if they could have controlled themselves. Sitting in a chair was easily the largest man they'd ever seen. In fact, he was easily the largest man to ever have existed. Everything about Evan's body was amplified on the Alpha in front of them. His pecs were bigger, his feet were bigger, his whole body was harrier, his abs were more defined, his face was more gorgeous, and his beard was more full. Even sitting, Dylan was taller than the two boys.
Both Sam and Austin dropped to the floor, cumming the moment they saw Dylan, who couldn't help but enjoy the new power he had over others. Evan had rejoined his Alpha and was stroking Dylan's massive, hard cock with both of his hands. They watched Sam and Austin writhe on the floor, lost in complete bliss. This went on for several minutes before Sam and Austin stopped and stood up.
In just that short amount of time, Dylan's pheromones had begun to affect them. Sam had grown a few inches and now his ankles were clearly visible below his now too small jeans. His shoes were getting tight and he could feel his own dick grow slightly, which was a problem because there wasn't much room in his jeans left. The tightness and growth was making him hard again.
Sam hadn't grown much in height, but he had put on muscle. His once toned arms were now much larger, filling out the sleeves of his shirt quite well. His chest had pushed out a magnificent pair of pecs that also strained his shirt. Creeping up his collar was a bit of chest hair, something he didn't have ten minutes ago. It went up and connected to the small amount of stubble that now covered his face.
Sam and Austin should have felt weird, but they didn't. They felt stronger, happier, and incapable of thinking about anything other than serving the Alpha before them.
"Take those pathetic clothes off," commanded Dylan.
Sam and Austin began to remove their tight clothing, but when they struggled, Evan got up to help them. He grabbed Sam's shirt with one hand and ripped it clean off, exposing a nice pair of pecs and set of abs, covered with a light dusting of hair. Evan went to help Sam, who was not so short any more. He grabbed his jeans with one hand and ripped them clean off, revealing a pair of tall, toned legs, and a rather impressive bulge in his underwear. It was nothing of course compared to Dylan's or even his own.
Evan felt a twinge of jealously. It had been days since his last dose of the potion and the feeling of growth it caused was so orgasmic that he wanted more. Despite constantly being in Dylan's presence, his own growth had slowed. Evan figured it was because if he grew much more he'd end up bigger than Dylan again, which is something Dylan would NOT have wanted.
Dylan watched Sam and Austin as they worked to finish undressing. Evan slipped back upstairs to check the vial once more. He found it laying on the floor, empty. But as he picked it up, he saw that there was one drop left.
