Testing the limits of reality

Alex looked at the still impossibly huge dick Brian was sporting, that very slowly went down, and the stain of his cum slowly dripping down the wall. Sure, he got a point, they should figure out what that ring can do... but then Alex somehow was also deeply afraid of it's power.
"We got class in a minute or so..." he reminded Brian.
"You got an all powerful magic wishing ring that can change reality, and you want to go back to class?" Brian asked confused.
"I.. I am just not sure we should use such power." Alex looked around for some argument briefly. "What if I had wished your dick to grow a third time, and you ended up with a cock too huge for your body to support?" That sounded plausible, but also caused Brian's dick to twitch and go back up again. "Dude... are you really so much into big dick?!" Alex rolled his eyes.
"Sorry, I just imagined myself walking through school with my pole scratching on the ceiling... and... hmmmffff-uck." Brian's dick was up to full mast again. "Damn... how am I supposed to get this thing back down if you keep talking dirty to me?!" he joked.

"Anyways, I think we should first figure out what this ring can, and cannot do." Alex noted. A part of him wanted to sit down on the toilet seat, but that would put him at eye-level with Brian's mega dong, and this wasn't something he wanted to risk at his aroused state.
"Well one thing I can say though is that the ring doesn't alter memories or anything." Brian pondered "When you turned me into that girl, and yes I too do miss those boobs, I was fully aware that you changed me."
"Cathy seemed to not realize anything though." Alex smirked when he summoned the image of her working his prick once more.
"Well she did seem pretty startled afterwards." Brian remembered, then suddenly had a revelation. "What if... you wish for the person... no the whole world to not notice?" They stared at each other for a moment as those thoughts were processed. "Holy fuck, you could make yourself the president and everyone would think this is how it has always been like."

Alex stared at him, and it dawned what power he was holding if that was actually possible.
"We totally should test that." Brian decided "Maybe not the president thing, uh... quick: wish something on me so obvious that I just have to notice it, but wish that... it had always been like that." he constructed an idea in his mind, then quickly added: "And only you know."
"Ok... I uh... I wish..." Alex started, but Brian stopped him.
"Don't tell me, duh!" he looked around, but then eventually just pushed his fingers into his ears. "Ok, do it."
Brian watched Alex looking at him dumbfounded, but then a naughty grin came over his face, and Brian knew: whatever would come next would be as perverted as fun. Alex raised his hand over his mouth, so Brian couldn't read his lips, and then spoke for an awkward long time, before he signaled Brian with a thumbs up that he was done.

"Sooo.... any guess?" Alex could barely hold back his laughter, so Brian figured it had to be something very, very obvious. First check confirmed that Monster Dick was still in place, and so were the Monster Boobs. Ass still magnificent, and her body also. No irregular thoughts on her mind, nor any urges other than the usual. Brian was mostly clueless about what the change might be, until a strain of her pink hair fell into her field of vision and gave her a clue.
"Ooooh... you made my hair pink, did you?" she wondered, but then remembered that she actually dyed it last weekend. "No wait, I did that. Or did you did it and made me think I did it? Fuck..." she gave up confused eventually. "Ok, no clue buddy, tell me."
"You... really don't know?" Alex asked, as the change was so damn obvious.
"Literally, absolutely no clue, sorry." Brian answered.
"Ok... then I wish you remember how things had been before my last wish." he eventually made her remember.

Alex had been expecting Brian to burst out in laughter over the obvious, comical change of turning him into a big-titted futa. After all he was watching porn of those often enough, and now he got to be one, even if it was just in an alternate reality. But instead of laughter, Brian's face turned into shock, then despair, and then she started crying.
"My... entire life.. is a lie." she suddenly bust out in tears. "Nothing of this is real..." She broke down onto the seat of the toilet. "When I hit puberty and got these..." she lifted her tits. "My first time with you.... my boyfriend. FUCK! My boyfriend, that I love more than life, doesn't even exist!" It became clear to Alex that this didn't went as planned at all. There was only one way to fix this.
"I wish that my wish to make you a futa was undone, and that you don't remember any of that life."

Brian stared at him in panic briefly, but then suddenly couldn't remember why. He was sitting on that toilet, clearly crying, but had no clue what cause it.
"What... h-happened?" he wondered.
"Believe me, you don't want to know." Alex returned and gave him a hug. This was his best friend, and the whole thing totally backfired to a point where he honestly considered flushing that ring down the toilet.
"I just know that I have been completely devastated just a moment ago." Brian scanned his memory. "Yeah, maybe I don't wanna know why." He enjoyed the hug he was getting for a moment, and somehow it felt well deserved. "What does that tell us about the ring's powers and limits though?"
"That there are no limits, and that we should be damn careful what we do with it." Alex summarized.
