2 Days Later
Harry woke up to feel his mother's familiar body wrapped around him. Her generous bosom pressed into his chest, her arms were wrapped fondly around him, and her head leaned against his neck. Lily was barely clothed, clad in lacy green panties and a loose, silky gray shirt. Harry's hand slipped up it, rubbing up her stomach, which was currently flat but would be swelling up over the next few months. His hand reached her tits, and he enjoyed playing with her nipples while she slept, though she did begin to wriggle.
Harry dropped his mouth to his mother's neck and kissed her there hard. Lily's emerald green eyes, the same shade as Harry's own, fluttered open, and gave Harry a warm, loving smile. Lily slid up and planted her mouth on Harry's. The mother and son exchanged hot, sloppy kisses, and Harry's tongue entered his mum's mouth multiple times, their tongues playing with each other. As they kissed, his hand came up to play with her fiery red hair while his other slipped up the back of her shirt and rubbed her back.
Lily shifted so she was properly in Harry's lap, and began grinding on his cock, though it was covered by boxers. Lily's weight in his lap felt heavenly, feeling her curves, smelling her warm vanilla scent, tasting her lips, hearing her soft familiar whines of pleasure. She lit all of his senses on fire, and Harry wouldn't have it any other way.
"Baby.." Lily moaned desperately, and she pressed herself hard to Harry. The mother and son were so madly into each other that sometimes there truly was no way they could be as physically close as they wanted. Right now, they had the option of stripping down and fucking, but once Harry was sheathed in her now very familiar pussy, there really was no way they could get closer, physically speaking.
"I love you." Harry groaned, and Lily breathlessly said it back to him. The mother and son duo could have spent all day there in bed, kissing furiously. Eventually, they would have stripped off their clothes and gone from cuddling to hot and heavy sex.
But it was not to be. There was a loud crack, and Konroy the house elf, a grungy little bastard who would often stare longingly at Lily, appeared standing beside the bed.
"What is it, Konroy?" Lily asked, looking his way.
"Letter for you, mistress." he said eagerly, and Lily took it.
"Thank you, Konroy. You can go now." she said. Konroy bowed low and vanished with another crack.
"I hate that prick." Harry muttered. Lily laughed.
"He's a huge perv, but he's an excellent servant." Lily shrugged, drawing Harry's eyes to her bouncing pale breasts.
Lily opened the letter then, and she unfolded the paper inside and began to read it.
"Well, it seems like we aren't going to be spending all day in bed." Lily mused with a smile.
"Who's it from?" Harry wondered.
"It's from Apolline. She's hosting a big party for Gabrielle's birthday tonight." Lily explained.
"Her birthday's tomorrow, though." Harry frowned.
"Perhaps tomorrow's going to be a bit more reserved in festivities, with a much smaller guest list." Lily suggested.
"That's probably it." Harry agreed, "So what time's the party?"
"Not until 6. Which means… we have time for a few rounds if you're interested." Lily grinned. Harry grinned back at her.
———
"Merlin, I'm sore." Lily groaned as she and Harry Apparated onto the grounds of Delacour Estate. The letter had said to dress very fancily, and so they had. They'd both needed a long shower to clean up, after several rounds of sex. Harry recalled the feeling of his mother's scorching pussy as he'd pounded her hard, made her scream his name.
The Lily before him now was a far cry from the sweaty, euphoric lust-drunk woman he'd been fucking all day, but she looked equally sexy both ways. Lily was now clad in a corseted green ballgown which, pushed up her delectable breasts and created some mouthwatering pale cleavage.
Her red hair streamed down her shoulders in vibrant waves and a golden circlet sat in her hair, with a winking emerald in the center. She wore a necklace that also had a glittering green jewel, and said jewel rested on the top of her breasts which only drew more attention to how well endowed she was.
Harry was in black dress robes, except for an emerald green tie that matched Lily's dress. Harry offered his mother his arm, and she took it, pulling it nearly directly against her tits. Harry smiled happily that his mother knew of and supported his love of tits.
Mr. and Mrs. Potter, as their invitation said, approached the grand staircase at the entrance of the Delacour Estate, and they handed their ticket to a guard, who took it, glanced at them, and nodded.
"Welcome to France, honored guests." he said in a heavy French accent, "You two have a marking upon your invitation that instructs me to send you directly to the Delacours, but I'm afraid they're busy hosting the esteemed Malfoys right now. If you two do not mind waiting, you're welcome to begin the festivities, and I shall have someone come and collect you when the Delacours are available."
"That's perfectly fine, thank you." Lily smiled, and the guard couldn't resist eyeing up the attractive redheaded woman. Harry had grown very accustomed to this, and he wasn't bothered. He had unyielding confidence that he was the only man his mother would ever be with now, and with that reliability existing, Harry didn't mind other guys ogling Lily. She was a queen among women, after all. She deserved to be revered. So long as they made no unwanted physical contact with her, Harry was content to stand there and let them ogle, reveling in the fact that Lily Potter was all his.
Harry and Lily entered the party and Harry was surprised to see just how many people were present. He hadn't seen a party of this magnitude since… this might even outclass his birthdays. The Delacours were remarkably connected, weren't they?
"Harry!" an excitable voice called, and Harry smiled to see Astoria Greengrass coming towards him. She wore a lovely pink gown that emphasized how insanely big her tits were now.
"Are they getting bigger?" Harry asked in amazement. He'd just seen her two days ago and she looked significantly bustier. Astoria blushed madly.
"They have gotten bigger. Mum and I had to buy all new bras yesterday." Astoria admitted.
"Wow. How big are they going to get?" Harry asked curiously.
"No idea, but I hope they stop soon. They're so big now." Storey blushed adorably, "I can't lay on my stomach anymore."
Harry laughed and pulled in the dark-haired younger girl, and she cuddled up against his chest happily.
"Fuck, they feel fantastic pressed against my chest." Harry grunted, and Storey beamed.
"Daphne did say you'd love them." Astoria admitted.
"Oh, I definitely do." Harry chuckled, "I'll talk to Freya about them when I get home."
"Why wait?" Astoria asked, "There's plenty of rooms in this estate."
"She makes a good point." Lily agreed.
"Alright, let's go, you two." Harry said, and Lily looked surprised to be included.
"What, you think I'd leave my date by herself?" Harry grinned. Lily smiled.
———
Harry, Astoria, and Lily slipped into an empty side room, and Lily locked the door.
Harry closed his eyes and touched his pendant. Mentally, he repeated Freya's name over and over again until he felt her presence. It took all of thirty seconds for her to appear.
She appeared dripping wet and entirely nude, her blonde hair soaked and pasted to her shoulders. Freya's gigantic tits were bare and wet, and Harry really enjoyed that view. Her full curves were also bare and wet, just like the rest of her.
"You interrupted me in my bath." Freya smiled playfully.
"I'd give you a hug, but I'd rather not get my dress robes wet." Harry laughed.
Freya snapped her fingers and suddenly she was entirely dry, her hair regained its usual luster, and then she held out her arms with a smile.
Harry wasted no time in getting to feel up her divine body.
"So, to what purpose do you summon me?" Freya wondered after their hug and lengthy kiss ended.
Harry stepped back and put a hand on Astoria's back, who shyly stepped forward.
"Thank you, Freya… for saving my life." Astoria inclined her head.
"All I did was provide the magic. Your love did all the work." Freya smiled warmly at the young girl.
Storey looked at Harry with loving eyes, and Harry kissed her on her soft lips, making her blush and smile.
"So, Freya, I was hoping you could tell me why, um…" Astoria fidgeted a little.
"Her tits keep getting bigger." Harry finished. Freya laughed.
She stepped forwards and cupped Astoria's cheeks.
"I'm sorry if your new bosom is somewhat problematic. I actually had no control over that, it was a side effect of my magic being so heavily based in fertility." Freya explained.
"Well, 2 days ago, they started swelling even bigger." Astoria explained. Freya raised her eyebrows in surprise, then realization dawned on her.
"Did Harry fuck you for the first time that day?" Freya wondered. Astoria blushed furiously but nodded.
"That explains it. Harry is my champion, and he himself is affected by my fertility magic. His must have reacted with yours to do… that." Freya gestures to Astoria's heavy boobs.
"Will they get bigger each time Harry fucks her?" Lily wondered.
"I don't believe so." Freya shook her head, "But I'd expect them to get significantly bigger in the next few months."
"Why's that?" Astoria asked worriedly.
"Why, your pregnancy, of course." Freya said in surprise, "You didn't realize? Two people enchanted by fertility magic fucking equals at least one baby. There's not even a chance of you not getting pregnant if he came inside you."
"But, I… I'm on the birth control potion." Astoria said in shock.
Freya giggled.
"My dear, do you really think a potion can stop divine fertility magic?" Freya asked.
Astoria touched her stomach in awe, and she looked to Harry with wide eyes. Harry felt similarly wide-eyed.
There goes his resolution to not get any more girls pregnant for a while.
