Greg could hear the emitter whir to life. He rushed forward trying to somehow stop whatever it was about to do. He was only a few feet away from Mike and Brian when he suddenly felt a strong urge to pull his hands up to his armpits, forcing each arm into a "chicken-wing" position. He couldn't understand what he was doing and yelled out "Mike! Don't you ... berk ... buc, buc, BUCAAWWWK!"
Greg's eyes widened in horror. Did he just cluck like a chicken?! It felt like he no longer had control over his body as he began lightly flapping his "chiken-wing" arms and strutting around like a chicken would. The strange bobbing movement caused his towel to unravel and fall to the ground. Both Mike and Brian couldn't believe what they were seeing - Greg strutting around butt naked while flapping his arms. Greg's dick flopped around comically between his legs as he walked, only adding to his humiliation.
Greg let out another "BUCAWWKKK!" while giving an evil eye stare at his younger brother. But he could do little else to change his situation. His naked body continued to strut around the room.
"Holy shit! This is awesome! It really fucking works!" Brian exclaimed as he began laughing. Brian was the one who suggested they try making Greg act like a chicken - though he thought it was just a joke, like it would just make it happen on the computer screen.
Mike finally got up the nerve to get up and walk over to his chicken-brained older brother who used to pick on him and was always the one in charge. "Hey Greg, remember how you used to call me a big chicken when we were younger? Who's the fucking chicken now!"
"Buc...BUCAWWWK!" Answered Greg while he flapped his arms a little harder, trying desperately to break free of whatever was causing him to do this. He only succeeded in looking more ridiculous and causing his dick to flop around even more.
"Oh just you wait Greg, I've got even more I want to do with you!" Mike said as he headed back towards the computer.
