Ginny was waiting for Hermione in the common room when she returned to Gryffindor Tower. "What's up?" asked the ginger-haired girl.
"I have something to show you," said Hermione, with a wicked grin on her face.
Ginny raised an eyebrow. "What is it?"
"Malfoy," said Hermione, pulling the tiny boy out of her underwear and holding him up.
Ginny gasped in surprise. "What did you do to him?"
"I shrunk him down to size," said Hermione, giggling. "He's been stuck up my butt for the last half hour."
Ginny burst out laughing. "That's amazing! You're so clever, Hermione." Malfoy tried to speak, but the girls couldn't hear him. His voice was still too small compared to their own. Ginny looked down at the tiny boy, smirking. "Did you enjoy Hermione's butt, Malfoy?" she asked, taunting him. Malfoy scowled, but there was nothing he could do. He was utterly at the mercy of Hermione and Ginny.
Hermione watched as Ginny approached closer to Malfoy, reaching out to poke him with one slender finger. Malfoy bristled, struggling to break free of Hermione's grasp and make a run for it. However, he was too small and powerless against the two young witches. Ginny grinned mischievously before scooping Malfoy up in her hand. She did not attempt to be gentle as she examined him.
"Watch it," barked Malfoy as Ginny's giant finger came into contact with his crotch. The huge girl just laughed, enjoying seeing the tiny bully squirm. To humiliate him more, Ginny decided to rip off his clothes. Malfoy's cheeks turned bright red as both girls giggled at the sight of his naked body.
Ginny dropped the tiny boy onto her bed. "I think you should spend some time with my butt now." Malfoy's eyes widened in fear as the red-haired girl pulled down her skirt and underwear, revealing an extremely white butt. He tried to run, but Ginny was already sitting down. The squishy skin of her backside engulfed him, pinning him down. It was like being sat on by an elephant, but miraculously, Malfoy was not crushed to death. Ginny wiggled around, in part to humiliate the bully and in part to get him secured between her butt cheeks.
Once the tiny Malfoy was secured, Ginny stood up and let her underwear snap back into place. He was still in disbelief that these girls had shrunk him down and trapped him in their underwear. Although he felt disgusted and humiliated, he couldn't deny the strange feeling of arousal that came along with it. Hermione and Ginny laughed as they watched their captive squirm around in Ginny's underwear. "He looks like he's enjoying himself," remarked Hermione, amused.
Ginny smirked. "It's funny how these big, tough guys can't handle being dominated by girls."
Malfoy, feeling angry about the injustice of the situation, yelled, "You'll regret this, Granger. When I get out, I'll make sure you pay for this."
Hermione just rolled her eyes. "You're not getting out any time soon, Malfoy. And by the time you do, you'll be begging for mercy." Malfoy struggled to free himself, but it was no use. He was trapped in Ginny's underwear, at the mercy of two powerful witches. He could feel himself getting increasingly turned on by the situation despite his efforts to resist it. It was a strange feeling, but one that he couldn't deny.
The girls decided to go for a walk around the lake while Malfoy remained trapped. Each step Ginny took bounced him around. Malfoy couldn't believe what was happening to him. He had never felt so small or powerless in his life. He was entirely at the mercy of Hermione and Ginny, and he had no idea what would happen to him next. As they walked, they talked and laughed, completely ignoring their captive in Ginny's underwear.
Finally, after what felt like hours, the girls returned to the castle. Malfoy was relieved when he was pulled out from beneath the fabric. "So Ginny, what should we do with Malfoy now?" asked Hermione.
"I have just the idea," replied Ginny mischievously. Malfoy gulped nervously, awaiting the next horrible thing the girls would make him do.
1. Ginny suggests they make Malfoy massage their feet.
2. Ginny says they should deal with Malfoy once and for all...by swallowing him alive.
3. Ginny dares Hermione to put Malfoy in her bra.
