Sam's lust is stonger than friendship, apperently.

"What are you doing?" You ask, watching Sam pick up the pencil as you hover over him.

"I've never been that drained after busting a nut, and my dick is too sensitive to put away right now." He said. "So I'm giving us an energy boost."

John and I can never run out of cum, our cocks never need a recharge time after having an orgasm, and our stamina is limitless. We both notice this change.

Sam sighed and smiled as the last period was added, and you gasp as a roaring rush of vitality floods through every fiber of your body. You feel like you could take off running right then and there, never bothering to stop until you became bored with running circles around the entire planet several times. However, you settled for eagerly bouncing on your heels to help disperse your limitless energy, cauing your huge steely dick to flop up and down in front of you.

"Much better." Sam sighed, leaning back in his seat as he grabbed his dick with one hand and casually began to stroke it. "How did I not do this as soon as I got this notebook?"

"Great question." You chuckled. "But instead of worrying about that, let's think about what to do now."

"Hm." Sam mumbled, smirking at your big dick's up-and-down wagging mere inches away from him. "How about we get someone to help us test these things out? Unless, y'know, you wanna get down on your hands and knees and do it yourself."

"Yeah, like that'll happen." You say with a roll of your eyes, too distracted by your bouncing dick to realize that Sam is discretely jotting something down in the notebook. "I am down to have a guinea pig though, how about-"

John is a submissive bisexual, and he will suggest that we use both of our moms as test subjects.

"-our moms?" You finish with a laugh, ceasing your energetic heel-bouncing. "We always joke about fucking each other's mom, after all."

"Great idea!" Sam said, his lusty gaze looking up to meet your own as he continued to openly masturbate. "My mom is downstairs already, but we can just teleport yours over here in a flash, if you want."

"What's the rush?" You ask, slowly dropping down to your knees next to Sam, to which he response by blushing and hesitantly turning to face you with his short but powerful legs spread. "I did say I was willing to do it myself, after all. Just have her drive over here so that I can take my time with this bad-boy."

Sam gasped as you boldly reached forward and grabbed his mighty cock with both hands, unable to wrap your thin fingers around its incredible girth.

Even though you both had known each other for quite some time, you became much closer after you became young adults. However, this time was different from all of the other times you've let your hunky friend treat your mouth and ass like onaholes for his average-sized dick. Now Sam was packing something that could do some serious damage, and judging by how you could barely fit just the head of his salty cock in your salivating mouth in that moment, you weren't sure if actual sex was even possible anymore.

Still, that didn't stop you from working Sam's cock for all it was worth. You savored each and every one of his lustful grunts and expressions, especially the way he'd wriggle around in his cheap desk chair and curl his toes into the same soft carpet your knees were digging into. By the time your mouth had worked its way down to his massive balls to begin licking and sucking on them, you could feel his rock-solid fuck-stick already on the verge of blowing its load.

Eager for a taste, you bring your lips up to latch them against head of his wildly twitching cock just in time to get a mouth and throat full of Sam's hot seed. As expected, its too much for you to handle, and cum sprayed out from both the sides of your mouth and your nose. You fall back onto the carpet, coughing and **** with a thick white coat of jizz on your face and upper-body while Sam's fat cock continued to bob and pump out more globs without anything touching it.

"Oh my god, bro..." You hear Sam say as you catch your breath and clear your throat. "That was awesome!"

"Tell me about it!" You laugh. "I used to be able to swallow everything you had, but now I-"

You sit up on the floor, wiping your eyes mostly clean of your best friend's cum. Sam is standing over you and disrobing, and you can't help but shut up and do the same. In a few seconds, you're both naked and dry, having used your useless clothes to wipe yourselves clean.

Watching as Sam wordlessly bent over the table and began to scribble in the notebook, you start stroking your pent-up dick with excitement.

"What'cha doing?" You ask, completely unafraid of what words were being written in a reality-warping notebook. In fact, the suspense was only turning you on more.

"Getting your mom to come over." He said, grinning like a psychopath. "That, and this."

John's mom Wendy will decide to come over and visit as soon as possible. John and I, including everyone that is blood-related to us, have bodies with indestructible elastic properties. John has a massive round ass, a slender waist, and he will cum on command if someone tells him to do so. Both of us will notice these changes.

Sam dramatically tapped his pencil, and you suddenly feel your entire lower-half and midsection light up with pleasure. You look down to see your thighs and hips expand and fill out with supple flesh, all while waist begins to shrink, tighten, and become as flat as a supermodel's.

In mere moments, you became the perfect embodiment of what a well-hung femboy should look like, even though you still almost had a full foot in height over your bodybuilder counterpart. Your hands reached forward with lustful amazement at your transformation, exploring the hairless sensitive skin on your new figure. After standing up and catching a glimpse of yourself in a nearby mirror, you could see that your shelf-like ass was just as big as a Kardashian's, if not bigger and bouncier.

While you chuckled and gawked at your reflection and new-found twerking abilities in amazement, Sam smirked and opened his mouth.

"Cum, slut."
