What Dan didn't know was that the spell he had chosen was not a normal one, one that shouldn't even appeared on the site. It was a spell left behind by a Witch from the days of myths and legends, where the creatures he fantasized about had roamed alongside humans. She had loves another woman among such beings numbers, and thus it was inevitable she would create the curse Dan had discovered when humans drove mythological beings out of existence only to survive as legends discarded as make believe. For the death of her lover, a kitsune to be precise, the witch swore to make humanity pay. When men burned her at the stake, she promised with her last breathe they would disappear from the earth, leaving only love and beauty like her own.
It was such a curse that it was buried, needing time to grow, to gather energy to work. And then it required a catalyst, someone who met the conditions for the spell. It had to be cast by someone in love, someone who desired the existence of mythogical creatures long past, and who they themselves knew not of magic nor had the real potential to cast a spell, and to top off the absurd requirements it was as if the curse itself embodied irony that would please the witch's revenge best. That the caster be a male who loved another man, so that as her curse specified, they would cease to be male and embody her love.
So it was that as Ian spoke up to Dan he would rise from his chair, grunting as he turned to his friend, only for Dan to watch as Ian's hips and ass expanded rapidly, pushing his pants to the breaking point as both boys began to hear them tear as Ian winced. However, the curse did not simply end at Ian, as Dan began to feel his body tingle as well, making him moan and gasp as he watched two massive mounds begin to balloon from his chest, the boy's nipples swelling and perky beneath his stretching shirt while Ian watched wide eyed. Neither would have a moment to even ask what was wrong as Ian's own breasts pushed outward, tenting his shirt as he moaned in what was now quite obviously a woman's voice. The sound of it making both boys blush before they shook their heads, noticing after doing so as they looked at one another that their faces were those of lusty girls. "W-what's happening Da-Ooooooooooooh~
