She then remembered the time she used a muscle growth spell, two years prior, trying to remember the name of the spell, her muscles started growing, with her sleeves becoming tighter and tighter, until bursting into shreds revealing large rippling arms, her legs likewise also put on muscle-mass, although not visable, her torso gained a lot of muscle. hermione tried to shrink her new muscles but for some reason, can't. She hurried out of the library to look for her friends.

She found her friends, Ron and Harry in the gryffindor commonroom. instead of shock, they complimented her, "looking good Hermione, now your brain and brawn". She was so happy that decided to use the spell again, her muscles swelling, causing her sweater to rip to shredds, her arms growing bigger, her legs growing bigger, her enlarged back muscles were now visable thourgh her shirt and the buttons on the front looked ready to burst. Hermione told her friends to grab her arms as she did a double bicep flex to showcase their size, being slightly bigger than their heads, after that show of power, she run off to the room of requriement to posssibly grow in peace. Ron was drooling at the sight of her.

Hermione was close to the room of requriement when a piece of debris block her path,"o come on, don't have time for this", She tried to move the rock but cound't move it, so she used the spell again, unaware a ravenclaw girl was close behind her.

"you look strong, how about giving us a show" the girl said seductivly, Hermione decided to give them a show and started flexing, with the Hufflepuff girl feeling her arms and back, and the Ravenclaw girl feeling her legs, chest and abs. when the muscle worship session is over, the Hufflepuff girl left, swearing not to say a single word about this, and the Ravenclaw french-kissed hermione causing a make-out session that last 15 minutes before leaving. Hermione nipples started hardening after that. With that detour over, Hermione reached the room of requirement spotted Draco down the hall, talking to goons. She considered beating them up but she decided he's not worth the trouble, she arrived at the room of requirement with no further distracions.
