Costume Mishap
Unfortunately, the mask he prepared for the occasion got messed up the very morning of Halloween. Desperate for a replacement, he bought a surprisingly well-crafted mask from a shady costume store.
He hurried home to prepare and tried on the costume before the party. Putting on his suit, gloves, and shoes, he had a brief lament over his underdeveloped body. It pained him how his body refused to build any significant muscle, but at least it’d help presenting a creepy look for Halloween.
As he at last put on the mask, he realized he hadn’t even tried it on before purchasing it. A strange but pleasant floral scent mixed with a sweaty masculine musk filled his nostrils as he breathed in through the mask.
With each breath he took, an odd empowering feeling flowed through his body. Sensation of cramps and stretched skin accompanied a sense of power foreign to him. He let out a deep powerful roar as he tore his constricting suit to pieces.
He looked down at the strong, muscular body hidden under the destroyed suit. Shock, confusion, joy, and desire intermixed in his mind as he tried to comprehend the unbelievable sight. He couldn’t help but flexed, groped, and posed in his new body as he processed the transformation. Seems like his idea for the costume was beyond recovery now, but a better opportunity presented itself. This year’s Halloween party was going to be a different kind of fun for him.
