"Ron, you git!" Harry yelled as he glared at his best friend. "What'd you do that for!?"
"Do you feel anything different mate?" Ron asked, seemingly ignorant to Harry's fury.
"I feel angry at you, but that's not the magic talking!" Harry growled. But, other than his anger, he didn't feel anything right now. "What does the spell do then? If I'm gonna be dealing this for however long I wanna know what you hit me with"
"I dunno, it just sounded interesting." Ron shrugged, making Harry glare at him even harder. "Oi, I couldn't understand what it said!"
Harry snatched the book from him and, after reading through the page, quickly understood what Ron meant. The language of this book was not one he understood, not in the slightest. Maybe Hermione would know, but right now he'll just be keeping this from Ron.
"Okay, I'm definitely keeping this from you until we get this to Hermione." Harry exclaimed. "and you, are not going anywhere near this until we find out what you cast on me."
"Alright alright!" Ron replied his hands up slightly in surrender. "Keep it mate."
"I need to go to the bathroom, so I'll meet you in the Common Room." Harry sighed as he plopped the book into his bag.
"Alrigh' then." Ron nodded, picking up his bag. "I'll see ya in the Common Room"
Ron then took his leave, weaving through the bookshelves and out of the Library.
"Jeez, Ron is such a moron sometimes..." Harry muttered to himself as he took a right turn, up some of the stones stairs and on the hallway to one of the lesser used male toilets.
As he entered into one of the stalls however, he could feels something, well, off. His crotch, now that he was paying more attention, felt itchy and he could feel a pull against his underwear. The strange part though was the he didn't feel like he had an erection though.
Unbuckling his belt, Harry pulled his pants down as he could feel his cock throb, his underwear stretching as it twitched in the col air.
'Is it just me or does it...' Harry thought to himself as he felt it strain more against his underwear, throbbing once more. 'Look bigger?'
Maybe it's a trick of the eyes, or it's more erect than he though, but he didn't remember it fill his underwear this much. Adjusting his underwear, he could feel it throb again as he could feel his underwear shift slightly more with each throb. It was unnoticeable at first, but with each throb his undergarments shifted even further and his eyes widened at the realisation that yes, it was growing.
"W-what the-" He quickly ripped his underwear down, shivering slightly as his "wand" became exposed to the cold air outside. Before it had been a below average 4 inches, but as it twitched upward and become fully erect, it had inched it's way past 5. "T-there's now way...is this the curse?"
Well, it's not like he doesn't not like it, Ron was still a git for casting an unknown spell on him that, for all he knew, could have done something much worse, but gaining a few extra inches wouldn't hurt, right?
he still stayed stood as he raised a single hand to hold it, feeling it grow ever so slightly bigger with each throb. After this little spurt, as it reach nearly 6 inches, it began to stop and stay that size.
"This...isn't so bad." Harry mumbled. "Why's this a curse?"
He shrugged as he sat on the toilet and did what he was originally going to do there before pulling his pants back up, walking out of the bathroom and back into the halls.
Does he make it to the Common Room or does something happen?
