Both boys held their breath and stared at The Contraption. This is great, Charlie thought, as he gazed at himself in anticipation. With this, I can be bigger than everyone else on campus, and best of all, Lee will be the one who helped me get it. Just thinking about dominating every other guy was making him bone up. Suddenly, he heard the sound of liquid entering his tank.
Charlie quickly let out a groan as he had the sensation of tingling all over his skin. He began stroking his chest, his crotch, anywhere his hands could find, just so he could feel himself getting bigger. It was difficult to notice at first, but Charlie knew his body better than anything else, having studied it endlessly.
Under his groping hands, he first felt his chest swell ever so slightly. His nipples, being pushed away from each other, gently rubbed against the fabric, sending chills of pleasure down his spine. His shorts, which had previously been a good fit, began to feel too snug on his now ample butt. He instinctively reached down to adjust them, and himself, but found that there was no room to move around in them.
As his hands ventured back up, he noticed that his t-shirt no longer reached his waistline, leaving a good inch of his abdomen exposed. He rubbed it, feeling how much firmer it was, and was surprised that it seemed coarser somehow. Looking down in surprise, he was greeted by a much larger chest protruding in front of him, with a fair amount of hair peeking out from his collar. Charlie groaned as he saw how completely he filled out his overworked tee.
Charlie took stock of his surroundings as he heard the machine winding down. For the first time since the process had started, he looked at Lee, who looked somehow even smaller and more pathetic than before. He bent forward to look down at his legs, which erupted angrily from his tight -- and, by now, quite short -- shorts. The sleeves and armpits of his shirt were now so tight that he couldn't completely lower his arms without tearing them. Oh well, he thought, I won't need these soon anyway. All in all, he was quite uncomfortably stuffed into his clothing, but he didn't care. He was getting everything he wanted.
He gave a cheeky grin to Lee, who was looking expectantly. "Here, have some of my leftovers, pipsqueak," Charlie said in what he hoped was an intimidating voice. Though he had been pumped full of testosterone, height, and muscle, his voice appeared to be unchanged, which was well enough.
Charlie took a moment to take off his shoes, which had started to really bother him. He figured his feet would only continue to get bigger. It was slightly awkward to take off his shoes because bending down was much more difficult in his too-tight shorts. He was able to half-bend down and bring his foot up to untie it, and that was the only way he could get it to work.
While he was doing this, he experienced the sensation of shrinking, which was every bit as arousing as growing had been. It was as though he was exhaling after taking holding his breath for a while. His smaller size was more capable of untying his shoes, and he finished about the same time the machine did. Standing up straight, he noticed his clothes fit well enough for him to stand normally, which he was slightly disappointed about. He figured he must still have been at least 230 pounds, and possibly even leaner than when he had woken up this morning. Nevertheless, he frowned handsomely.
Lee piped up, “Look, you can see, your tank is still at twice the level of mine.”
Though this was quite an obvious observation, since Lee had barely grown, Charlie responded, "That's right, I'm twice the man you'll ever be. You remember that.” He smiled inwardly as both boys looked forward to the second round.
