Katie wasted over half a minute just staring at Tiff, before finnaly reacting.
"W-w-well... I`m not sure if we should... I-i mean, think if...-" Katie was interrupted by Tiff asked she started to giggle.
"Sorry, but it`s too late now... I Guess I get to do both!" Tiff looked at Katie for a few Seconds before smiling.
"Uh... Tiff, why are you smiling like that...? It`s creeping me out..." Katie moved back slightly, though she didn`t believe really believe in the curse, she still didn`t want to try it out... Especially not when Tiff was in Control.
"Now... For Your transformation..." She began to giggle, and pointed at Katie`s crotch. Katie, who became quite confused at her action, took another step back. "What`s wrong? It`s not like it`s real, so I`ll just do this for fun. Now... I`m gonna give you a big, thick cock! Like, about 2 feet long and, we`ll make it dark, just for fun! Along With it, you`ll get a large pair of balls!" She said while laughing, not taking this seriously. Though Katie had a bad feeling about this whole thing.
"A-are you thinking through this...? I-i mean, what if it really is re-" She was once again cut off by Tiff.
"And for Your dare, you will always feel an urge to stroke and touch it!" She started laughing again, patting Kaity on the shoulder. "Just kidding around here... Like I said, there`s no way that "curse" is real!"
Kaity laughed nervously, hoping that Tiff was right. But, after only a minute, Kaity felt something weird between her legs. She look Down to check. It felt like her clit was extending outwards, pushing against the fabric of her pink lace panties. "I-I... Something...Is..." She managed to mutter out as she moved her shaking hand Down to her crotch.
"Huh? What are you talking about? Are you trying to mess With me now?" Tiff laughed, and gazed down to Katie`s crotch. Katie was also wearing a pink, pleated skirt, where a small tent was forming. "Wait a sec... Is that...? N-no way!"
Katie let out a small moan as her New, growing member snaked it`s way out of her panties, lifting the skirt up along the shaft as it grew. After only a few Seconds, the Girls could see the head moving out from under Katie`s skirt. The shaft quickly followed, and Tiff quickly moved, but not fast enough, as the head brushed against her hip. "S-stop it...! Please!" Katie moaned, but Tiffo only watched as the giant cock slowed Down, growing the last few inches.
"W...well, at least it`s over..." Tiff said, trying to sound optimistic. But Katie shaked her head, and held her hands between her legs, under the cock`s shaft.
"Oohhh... I-i`m getting..." Katie stopped talking as a sack grew out from between her legs, two large balls filling it. "...Balls" Katie was now standing there, her large dick standing up in front of her face, and... a strange urge fell over her. She wrapped both of her around the Cock, and started stroking it uncontrollably.
"H-hey, Katie, what are you doing...?!" Tiff shouted, watching her friend stroking her male member...
