"But I wanted to be a player! I love being so huge!" you yell, scared of the hot cheerleader. You trip and fall on your massive ass, looking at her.
"That won't be a problem!" she says and smiles, looking down at the terrified and enormous football player she created. "You're not done GROWING!"
Your eyes become wide and the feeling of transformation comes over you again. The pads were already tight around your huge body, but now they feel much tighter! You can see how your already huge legs are becoming even bigger, stretching the material of the pants like it's going to shred. You raise your hand to see your fingers becoming much thicker and your entire palm much larger. Your huge hands tear through the gloves and reveal monstrous, hairy hands. You can see the hair growing down your arms, which are becoming much bigger and much longer.
"What's happening to me!" you yell, and she laughs.
The cheerleader sits on your heaving chest, which is growing bigger and bigger, her legs spread open in front of your face.
When you try to talk again, you can feel how your mouth is changing. Enormous fangs have grown where your incisors used to be. Your mouth is pushing forward, your brow becoming a thick cliff over your eyes. You bring your giant hand to feel how hair is growing on your face! You grunt, looking at the cheerleader's pussy. You grab her with one giant gorilla hand and put her aside, rolling on your monstrous shoulders, which are now bigger than the pads used to be. Somehow the entire equipment has grown to fit your new size.
You grunt and roar, banging on your armored chest as you rise to your feet. You stand at nearly nine feet tall, and you're broad and strong enough to tackle a train off the rails. Everyone looks at you, the massive anthropomorphic gorilla in football gear.
