{16th Oct 1991} 

{3rd person POV}

...

[Evelyn Rowle is channeling your special perk {Metamorphmagus}]

[Do you want to let her Mana Core get accustomed to the perk through the Core Expansion Ritual!]

[Yes/No]

...

Rigel stared at the screen for a moment before his eyes went back to the now enormous rack on Evelyn. She was staring down at her own breasts, hefting them up as she weighed them. He was tempted to do the same, but right now, he had a decision to make. The pros and cons of her having the Metamorphmagus ability were easy.

She could be a walking advertisement of the possibility, and even if nothing else works, he wouldn't have to work as hard to seduce the first years next year. The only downside was that she would permanently have that ability, and there was a possibility that her worth would increase so much that her father would reject her position and forever be beneath me.

'But I have quite a hold onto her psyche, she's addicted to the pleasure that I could provide so even in the worst case scenario I would be able to maneuver-' Rigel's thoughts were interrupted as he felt her pussy tighten on his cock before her insides started to massage his dick. He looked into her eyes but found them closed as she had a focused expression on her face.

Rigel mentally clicked on the Yes option, and the screen vanished in front of him. He focused on the enlarged breasts that were hanging just a few inches in front of him as he curiously grabbed onto them. They felt heavy as he repeated Evelyn's actions. He then extended his palms and tried to cover them as best as he could, but he still couldn't as flesh continued to spill out of his palm.

'I regret nothing...' Rigel declared as he leaned closer and popped her right nipple into his mouth. 

Once again falling deeper into the pleasure-filled abyss, Evelyn started bouncing once again, giving up on using her newfound powers to turn her pussy into an onahole.

"So, what are the chances of you keeping your newfound powers?" Rigel asked.

"Mhmm, I don't know. Lettsss~ enjoy this until the ritual lastss~" She moaned in reply, and I couldn't help but nod. In addition to the Metamorphmagus power, she was also able to channel his Mana sense skill. These are the two abilities that he gained from the Black family bloodline. He had rejected the Mana sense. It was a little too important for him to even think about letting her gain it, nor would he likely extend it to someone else.

'She managed to try both of them out, yet there was no notification regarding the Parseltongue. Is it really that special, or can it not be inherited like this?' Rigel speculated. Still, the sample size was too small for him to reach a conclusion, and as his pleasure started building up, he ignored those thoughts and focused on the now-enhanced bum that was smacking down onto his thighs. 

He sucked on her gigantic boobs, and his hands were wrapped around her huge ass. Sounds of flesh slapping against each other continued to fill the room as they both lost themselves to the base desires. After around 10 minutes of non-stop fucking, Rigel dumped a huge load into her pussy as he was now slamming into her. They had shifted from seated cowgirl to missionary pretty soon.

...

As he came down from his orgasmic high, Rigel noticed the change right away. His mana core was bursting with mana as he was in a hyper-aware state. At the same time as he had accepted, Evelyn's form remained stable even after the Ritual had clearly ended. He shifted slightly before he pulled out of her. His dick was borderline massive at the moment, as during their haze, they both had used their Metamorphmagus powers to redefine the term stuffed.

Evelyn was still a bit out of it, so he stood up and looked down at her. His cum was leaking out from her pussy. After staring at her new form for a bit, he stepped out of the ritual circle, which was now barely visible after it was drained out of mana.

'This wasn't so bad. Plus, she'll most likely use her new power for sex with me. I have so many ideas for making our evenings more enjoyable.' Rigel thought as he started getting dressed.

"Uhmmmm~" Evelyn moaned as she woke up. She wasn't out for long, but the pleasant ache that was coursing through her lower abdomen told a story of its own. Her hand went upward to rub her eyes, but it paused as it collided with something fleshy. Her eyes opened wide as she leaned up, the new weight added to her chest took some more effort out of her thin waist, but she managed. 

Her hands grabbed onto her new boobs as she focused, it was easier than it had been in the ritual, and she could feel them expand and grow heavier. She could feel her body tilting slightly under the weight, so she stopped, and she went back down to her normal size.

"Hey, what are you doing?" Rigel asked.

She turned to give him a questioning look. He rolled his eyes at her and spoke, "I didn't agree to this, so you could go back down to your normal size. Come on, it's like a crime for you to shrink your breasts. At least go up a cup size or two. Haven't you heard bigger is better?"

Evelyn heard her own words being thrown back at her. She had begged Rigel to stretch her cunt one day with that same line. With some focus, her boobs once again swelled; she took a little delight in the fact that Rigel's attention was focused on her expanding boobs; the look in his eyes, as his sole focus was on her body, did make her feel better.

"Now that's more like it... Say I have something special planned. Why don't you come to my room tonight, say around 8:30?"

AN- The chapter result is decided by a poll! Anyway, it's been a while, and life has kept me busy. It's been a bit difficult to write smut as of late, but I have figured out a way to keep at it. The updates from now on will be focused on just Saturday and Sunday, though hopefully I'll give you something new to read during the weekdays pretty soon, I have something in the works.

As always, 50+ advanced chapters on P.atreon!
