Drake guessed that he must be weighing around 300 pounds now, looking like a true bodybuilder and still growing bigger and stronger. His pecs kept pushing outwards, struggling against each other and the fabric of his shirt. He could feel the fabric sliding over his nipples, which were pushed further and further down by the incredible amount of muscle on his chest. Drake wanted to know how big he looked by now and decided to check himself out in the mirror in his room.
He almost came when he walked upstairs, as he could feel all the muscles on his body push against each other. Drake relished in the feeling of incredible strength and ever increasing size, chuckling at the fact that he had to waddle slightly because his quads were so big by now that he couldn't walk like he used to do before. For each step, he had to roll one leg around the other, and mounting the stairs thus proved an incredibly erotic experience.
Drake finally got to his room and placed himself in front of the mirror just in time to see the seams of his shirt start to give way, his pecs bursting through the fabric. He was amazed at his own bulk, at the way each muscle was ballooning outwards from his body, steadily increasing in size. He flexed his left arms, and the huge bulges of his biceps and triceps ripped the sleeves of his shirt apart. Drake roared, aware that he must now be around 400 pounds of pure muscle. A few more flexing movements took care of the rest of his shirt, and he expected the growth to stop.
His muscles kept growing, however, and he giggled when he saw that although his pants had long lost their fight against the growing amount of muscle on his body, he was still wearing his underwear. His butt was getting more and more muscular as well, however, and the fabric of his boxer shorts was already wrapped tightly around the hard and delicious mounds of his ass. Drake closed his eyes, concentrating on the feeling of growth, muscles pulsing and growing, and waiting for the fabric to give way. He must have been passing 450 pounds when the boxer shorts finally lost their fight, unable to cope with the sheer mass of muscle anymore; with one tearing sound, his butt burst through the fabric, and his underwear fell to the floor.
