Oops, a bit large!

Harrys jaw dropped. He did not expect that answer. But you never do know what to expect with Luna. "I, erm..." Why not, right? If she even offers herself for it, why not? "Okay, yes thanks, I will try it out on you then." Luna smiled in a friendly way. She seemed more like a person who is happy to spend some time with a friend than someone who would have their tits magically enlarged just so some guy could stare at them. Stare, and maybe so much more.

Luna walked over to a stone bench and sat down facing Harry. "Should I just sit down her like this and you can start?" she offered and Harry nodded. Luna had her robe open now, her rather small breasts were held in place by a blue cloth, tied with a loose knot in the front. Harry remembered all the complicated spells and hand movements necessary, tried to recall the exact shape and size of Susan Bones tits, a perfect pair in his mind, and began. With a low murmur, Harry pointed his wand at Lunas chest.

He watched, as Lunas breasts began to grow. It really did seem to be working this time. They grew and grew, more than just a little bit like last time, and soon her bra was pushed open. The remaining cloth was just barely hanging over her nipples on either side, but her breasts kept growing. Luna looked down now "Oh my" she said in an interested voice. Her tits grew even more, becoming even larger than Susans now. "You do like them really big Harry" Luna stated factually.

Fuck, this was not what he had in mind! Harry tried to make it stop and managed to do so, but not before Lunas tits grew to the size of big watermelons. Much bigger than Susans! twice as big, probably! For a moment, Harry just stared at her, open-mouthed. The blue cloth had long since been pushed aside. Lunas robe, even if she tried to close it was nowhere near big enough to cover her breasts now.

"I... I am so sorry Luna, I did not mean to grow them THIS big. I.. let me just try and...." Harry wanted to offer to reverse the spell, but his eyes were fixated on Lunas insane rack. "They do feel rather heavy," Luna said "I am glad I am sitting down right now." She was. She was sitting right in front of Harry, her enormous tits just at the right height to... "Well Luna, let me see how I did, apart from size" Harry said and slowly reached out for her boobs.

She did not make any attempts to stop him, not that she should have. He had every right to do this. Both of Harrys hands reached for one of her tits, his fingers sinking into her amazingly soft skin, sinking in deep. As he squeezed her, Lunas breast was so large and squishy between his fingers, no matter how deep and hard he squeezed down. He reached for her big nipple and found it hardened. "This... This does feel interesting Harry" Luna said "Nice, actually"

Harry now worked both of her enormous udders with his hands, lifting them up, heavy as they were and letting them fall down again. Fuck those were great. Almost unnatural looking just by their sheer size, but so fuckig fun to play with! As Harry started to grope, squeeze and tug all over her tits, Lunas face flushed and she said "Oh Harry this IS nice!" in an aroused voice. "You know with all going on the last days, I have barely ever been even touched and.. Ahhhh "

Some part of Harry heard her, but the main part of his brain was taking out his hardened cock. He stood right before the sitting Luna, his boner pointing right at her monster tits now. Luna looked down at it excitedly "Oh wow, will you use that one me now?" she asked. Harry did not answer. Not with words at least. Grabbing a good handful of soft tit flesh in either hand, he got a tight grip and pushed his hips forward. His dick was engulfed by mounds of boob on either side, disappearing between Lunas new breasts balls deep. No deeper even, his balls too were nowhere to be seen anymore!.

Luna let out a surprised gasp but she smiled up at Harry "It seems like you do like them" Luna stated, as Harry began to move back and forth between her fat tits, again and again. He picked up the pace, he was fucking the living hell out of those monster funbags. Coushined as they were Luna probably barely felt it. He was not gentle on her boobs, fucking hard between them, tugging and groping to his heart's desire.

After a few minutes, Harry came somewhere deep between her tits. He did not even see the load oozing out, it just got lost somewhere in there "Wow..." said Luna "Now that seemed like a fun time for you. I myself enjoyed it quite a bit as well." Harry panted and sat down next to her "Ahh.. Wow that was amazin gLuna. But now, let me see what I can do to get you back to normal again."

But Luna shook her head. "No thank you Harry. I think I will leave them like this. At least for today. As I said, I have barely been looked at before and I think that with these" she pointed at her new playthings. Harry shrugged "If that is what you want". Luna nodded and stood up. She took a step but stumbled, pulled forward by the unfamiliar weight in front of her. Harry watched her walk away.

As Luna crossed the path of a tall Hufflepuff he was staring wide-eyed at her insane boobs. Harry was happy for Luna, as he saw her being pushed down on all fours and mounted from behind, her fat breasts groped thoroughly. Maybe, she really did need to keep them this way. At least for a day of fun.
