A friend (and bro) with benefits

Mario sat down at the desk and picked up a pencil, and Vide floated over to look over his shoulder. Mario flicked the pencil in his hands like a small baton a few times, trying to decide on the wording for some of the entries he was about to make. He decided to write something for himself, first.

“Ooh, that sounds like fun!” Vide exclaimed after Mario finished, “Are they cute?”

“I don’t really know to be honest,” Mario sighed, “I’ve never seen either of them with their veils off, but they certainly sound cute.”

“I bet they’re cute,” Vide smirked confidently.

Next up, something for his brother. It was high time Mario helped him get hooked up. But if he made the transformation too quick, Luigi would know that something was up. Yeah, a slow transformation would be best. With that thought in mind, Mario set to work:

“Luigi Jumpman
“Everyday his dick’s flaccid size will grow by 1/16th of an inch until it has reached 5 inches in length. His girth will also go in relative size while flaccid until its circumference is equal to 3 inches.
“His erection size will also grow in relation to the size above until his length is 8 inches long and 4 inches circumference when fully erect.”

Mario had set the goal for more or less the same size that he had for himself. Eight inches was the bare minimum needed in length to be a male porn star, any smaller and they would be too small to show up on camera. As for the width, most dildos were typically three and a half inches in circumference, barring any weird-shaped silicone ones.

“Wow, you must really love your brother, huh?” Vide asked, “Most other guys who get the Tome hate competition, so they generally either make them beta cucks or femboys.”

“He’s my little brother,” Mario replied, “I gotta look out for him, you know?”

“Wait, you’re the older brother?” Vide’s eyes widened, “He’s almost a head taller than you!”

“Yeah,” Mario said wistfully, “We fought over it all the time as kids. I used to get really mad about it, to the point it almost ruined our relationship. But at the end of the day, I can’t control genetics.”

“You mean your parents couldn’t,” Vide smiled knowingly.

“The Tome can do that?” Mario looked sideways at her in surprise.

“You wouldn’t be the first guy to use the Tome of Fantasies to make designer babies,” Vide nodded, “Though it’s probably best that I left it at that.”

“Ew,” Mario’s lip curled, “I don’t wanna know.”

“No you don’t,” She agreed.

Mario checked the clock, he had time for a few more entries. But who to use it on and what for? Things were going good between him and Queen Toadstool right now, but he had no idea of how she’d react if he started sleeping around with other people. Perhaps it’d be better to nip that in the bud before it became a problem. Also, giving Luigi a bigger cock, growing at a speed that wouldn’t seem strange or out of place, was doing him a favor, but Mario wasn’t sure if it would raise his confidence in any meaningful manner. Also, there were some laws that Mario would like see get passed, and he could use the Grimoire to get Peach to pass them quite easily.

Mario nodded, those would be the entries that he’d prioritize for now. Time was of the essence, so the plumber got to work.

“Queen Peach Toadstool
“Will have no problem with Mario Jumpman sleeping with other people or building a harem.”

There, quick and easy.

“Oh, so you’re the type of guy who likes harems, huh?” Vide teased.

“What? Is that rare, too?”

“No, it’s actually a pretty common fantasy. For both sexes, even,” Vide replied, “But most people can’t handle the realities of managing one. I wonder…, no. You strike me as the sort of man who wouldn’t be put off by something like that.”

Mario hummed in acknowledgment as he wrote out the next entry.

“Wait…,” Vide frowned, “Who’s this ‘Mr. L’?”

“Let’s just call him my bro’s alter ego,” Mario replied, “A while ago, he was brainwashed into being evil and called himself ‘Mr. L’. He was far more confident, but also annoying. I’m hoping by bringing out a little bit of Mr. L, Luigi could be a little more of the former.”

“You sure you wanna risk messing with his personality like that?” Vide sat in midair, hugging her thighs to her chest. If this were a manga, there would be a sound effect for her breasts being squished. The position also gave Mario a fantastic view of the lingerie that she was wearing beneath her clothing. It did as little a job hiding her slit as her top did for her nipples. She caught him looking and shot him a look that said, “Like what you see?”

“I’m sure he’ll be fine with the proper supervision,” Mario answered her finally, “Unlike last time, I’m the one guiding him and we both have a great support system.”

“If you say so.”

Finally, the last entry. Mario doubted that the Grimoire Fantasia would just let him write out new rules for the Kingdom, even if the result would result in more kinky, sexy things happening throughout the entire Kingdom or if he simply used the Tome to mind control Peach. Besides, he had a more fun way of getting what he wanted done.

“Queen Peach Toadstool
“When visited in her bed tonight by Mario Jumpman, will ask his opinion on laws to be passed in the Mushroom Kingdom, and will be very susceptible to his suggestions, in particular about laws concerning nudity and sex. No matter how mind-numbing the sex is, she will remember his suggestions.”

“Nice embellishment!” Vide approved, “Going for a little mind break, are we?”

“I think I already did a couple times,” Mario smirked, “But now that you mention it…,”

“Queen Peach Toadstool
“When visited in her bed tonight by Mario Jumpman, will ask his opinion on laws to be passed in the Mushroom Kingdom, and will be very susceptible to his suggestions, in particular about laws concerning nudity and sex. No matter how mind-numbing the sex is, she will remember his suggestions.
During this particular sex session, she will temporarily suffer a mind break and think of nothing but how good Mario’s dick feels inside of her. She return back to how she was before once she experiences an earth-shattering orgasm.”

“Damn, you’re good,” Vide bit her thumb, “I’ve never looked forward to the end of the first day so much before!”

Mario smiled as he closed the Grimoire and placed it and his pencil into his pocket, “Glad you approve. Gotta say, it’s a huge turn-on to have a sex goddess praise your creativity.”

“Mmm,” Vide hummed seductively, “I wonder if there will be someone nearby that I can play with?”

With that, Mario climbed up the ladder, picked up a change of clothes and set back out for Toadstool Castle. On his way out, he talked to Tiptron again, “I’m headed back out. You have a nice night, Tiptron.”

Tiptron fluttered to the door of her cage, the movement meant to be smooth and organic came off as rigid and uncanny instead. Mario had long since gotten used to it.

“…Be careful, Master,” she finally told him.

Mario nodded and left.
