Hermione rides.

With a gentle nudge, Hermione encouraged Luna to slide off his lap, taking her place almost immediately. She straddled him, her own newly-enhanced breasts bouncing with excitement as she aligned herself with his erection. Her pussy was already slick from watching the show, and Harry's cock slipped into her with ease. She threw her head back, a gasp escaping her lips as she took him in, feeling filled in a way she never had before. The sensation was incredible, her new size making every movement feel more intense.

Her hips began to rock back and forth as she found her rhythm, her massive tits jiggling and bouncing with every stroke. Harry's eyes were glued to the mesmerizing sight, his hands gripping her waist to help guide her movements. The room was filled with the wet sounds of their fucking, and the occasional slap of flesh on flesh as Hermione's breasts smacked against her chest with every downward motion.

Luna, not one to be left out, knelt beside them, her eyes wide with arousal as she watched her friends in their passionate embrace. She reached up, her slender fingers playing with Hermione's nipples, rolling and tugging on them as the brunette continued to ride Harry. Hermione's moans grew louder, the sensation of Luna's touch sending bolts of pleasure straight to her core. She leaned down, capturing Harry's mouth in a fiery kiss, her tongue dueling with his as they fucked.

The tension in the room grew thicker, the air charged with sexual energy. Harry's hands found Hermione's breasts, his fingers kneading and squeezing the soft flesh. He couldn't believe the size of them now, and the way they moved with her every move was nothing short of hypnotizing. He watched in awe as she began to bounce faster, her breasts moving in a way that seemed almost unreal.

The three of them were lost in their own world of pleasure, the room spinning around them as they reached new heights of ecstasy. Harry's cock was a blur as he pounded into Hermione, her pussy clamping down on him with every thrust. Her moans grew louder, her body tightening around him as she approached climax.

Hermione's eyes widened as the orgasm washed over her, her body shaking uncontrollably as she cried out. Harry felt her pussy spasm around his cock, and with a roar of his own, he released his seed deep inside her. The warmth filled her up, and she collapsed onto him, her breathing ragged and her heart racing.

The three of them remained entwined, their bodies sticky with sweat and cum, for a few moments, basking in the afterglow of their shared pleasure. The tension in the room had broken, leaving only the quiet sounds of their panting and the gentle throb of their hearts.

"Harry. I'm never leaving your castle." Luna kissed him. "I want you to fuck me everyday."

"You've got yourself a deal," Harry said, a wide smile on his face. He looked at Hermione, who was still straddling him, her head resting on his shoulder, her breathing gradually returning to normal. "What about you, Hermione?"

Her eyes sparkled mischievously as she sat up and swung her legs over the side of the bed, the sweat glistening on her skin. "Hold that thought," Hermione murmured, her voice still breathless from her orgasm. She gracefully slid off Harry's cock and padded over to the nightstand where the potions remained.

Selecting the bottle labeled 'Permanent Enlargement', she uncorked it with a flourish and took a deep breath. "Here goes nothing," she said to herself, before downing the potion in one swift gulp. The liquid was thick and warm, coating her throat as it traveled down to her chest.

The transformation was immediate. Hermione watched in amazement as her breasts grew before her eyes, swelling until they were as large as the others'. She reached up, cupping the heavy mounds in her hands, feeling the weight of them. They were firm and full, with large, pink nipples that stood out like cherries atop a sundae.

"I guess I'm keeping them." Hermione smiled turning back to her lovers while holding her huge tits.

The room was still, the air thick with a mix of desire and magic. Luna, her own chest heaving, watched with envy as Hermione's breasts grew to match hers. Harry, still lying on the bed, his cock glistening with their combined juices, took in the sight before him with a smug grin.

"I think we need a proper celebration," Hermione said, setting the empty bottle down. She turned to face Luna and Harry, her new assets drawing their gazes like magnets. "A toast, to our new... assets."
