Amanda looked down at her clothes. Her shorts were literally ripped to shreds, with thick pieces of the material blowing gently in the morning breeze. Her tank top was also feeling about two sizes too small for her body now, with her giant breasts straining heavily against the shirt's fabric.

She knew she couldn't go to school like this, so Amanda took her brother's clothes out of her backpack and walked towards a secluded area a little ways ahead of her.

Amanda leaned up against a tree and began to undress. Tugging at the waist of her shorts, Amanda tore through the tattered material with one swift motion and threw the remains aside. She quietly put on Robert's shorts, noticing that even they felt a little snug on her larger frame now.

Next came the top. It was a little harder to remove than the shorts since it practically clung to her body like a second skin now, but she managed. Amanda took the top off as the bra underneath fell listlessly to the ground. She placed her tank top back into her backpack, since it was still salvageable, while she kicked the useless undergarment next to her shorts.

Her giant breasts barely moved, being supported by a thick shelf of pectoral muscles, as Amanda reached down to pickup her brother's shirt. Before putting it on, Amanda flexed her right arm once more. She saw the giant muscles of her biceps and triceps spring to life instantly and if she had to guess, would put its overall size at just a little over 18 inches. "Spectacular," Amanda said to herself, smiling.

She heard the familiar hum of the school bus engine so Amanda quickly put on Robert's shirt, grabbed her backpack and started running towards the bus stop again, amazed at how much faster she could run now.
