A skeletal outline emerged underneath the violent tornado that continued to spin around the room "YEE!" you could hear behind it as a torn shirt, then shorts, then socks and shoes went flying out of the tornado and toward the corners of the room. The body inside the tornado, through the flashing lights of green electric bolts, was growing with massive muscle. Jeff was becoming a jock. A bro. A completely fit and studded warrior, the muscle mass increasing as the tornado spun around the room. "Fuck yeah!" you heard it shout, the aggression, confidence growing on the man as his body continued to grow under the green flowing powers of the mask. One last rip and off went his underwear, leaving your transforming and spinning roommate completely naked. As he continued to spin, you can see the outline of his dick and balls growing in size and girth. The friendly nerd who was you roommate was becoming a complete frat bro, and his growing confidence was making him more comfortable to be in complete and utter nudity.
The tornado literally absorbed into Jeff as it slowed. The light, bright, shining green bulb of a mask over his head literally absorbed into his face and hair, soaking the green power of the mask into his body. But the bro underneath the mask looked nothing like Jeff. This man had a new, golden skin color, dark, thick curls of hair on top of his head, and a budding five o'clock shadow on his face. His sculpted abs and pecs had a thin line of dark, curly hair resting on it, and it gathered over his adonis in thick, bushy pubic hair that sat over his massive dick and balls.
The transformed Jeff was full of masculine muscle, and he exuded confidence and stamina like no other. "FUCK YEAH!" was the first thing that newly-emerged god shouted. "This feels fuckin good BRO!" he said, enunciating the "Bro" as completely confident in his new form. Checking himself out, Jeff took a huge bicep pose, flexing his arms toward his abs as he flexed, his adonis and pecs responding as his dick flopped over his balls.
"Time to join the alpha frat, Bro!" he shouted, spinning back into a tornado and knocking you to the side as he flung through the door of your dorm and out into the hallway.
You chased him down the hallway and out into the quad. "Wait! Jeff!" you shouted. Maybe he could help you become a frat bro, too?
