Blowjob time

Jack pulled down Derek's pants, revealing a huge bulge in his boxer briefs. Jack licked his lips again.

Derek looked down at him, trying to be intimidating, but goddamnit, that was really kinky.

"Jack, with all those people watching? Are you crazy?" Derek growled.

Jack's eyes lit up.

"With all those people watching," he whispered.

He pulled down Derek's underwear, revealing his monster meat. His dong, normally 8 inches long erect, was now almost the size of a person - roughly four feet. And it was rock hard and throbbing like hell, as the reality of the situation kicked in - Derek was about to be serviced, as a mighty giant, by his hot roommate, a lesser giant, with the whole city watching. Derek glanced down, only to see the crowd whipping out smarphones.

"Fuck, will the Pornhub servers even survive this shit?" Derek cracked a joke.

Jack gently kissed his fat tip before slowly taking the whole length in his mouth, savouring every inch - and there were more inches than usual! His throat bulged out as he took the entire thing inside him and began moving back and forth. Derek put his hands on Jack's mouth, enjoying the incredible sensation of his roommate's tight, juicy mouth and throat on his collossal dick. He moaned deeply, messing up the smaller guy's hair.

He looked down at the watching crowd and smirked.

"You fuckers are enjoying this shit? I'll give you something crazy."

He grabbed Jack's delightfully puny shoulders and rammed into Jack's face, throat-fucking him with incredible vigour. The sheer sensation of his own immense muscles moving got him hot and bothered. He noticed Jack's eyes were filled with tears, but his expression was disorted by his stretched-out mouth. Whatever, Derek thought, if he wasn't enjoying this, he would just get bigger and eat me or something.

Little did he know, Jack was loving this shit. The taste of Derek's sweaty rod, the sensation of his throat being used as a fleshlight, the godlike thrusts and monstrous moans of his roommate - all this was his dream come true. He was close to cumming hands free...

Derek felt himself passing the point of no return. He thrusted harder and harder, turning Jack's mouth into his personal fuckhole, as his eyes rolled back and gallons of cum cascaded straight into Jack's stomach.

Jack loved the sensation of salty man nectar filling up his guts. He had **** but to swallow every drop. He blew his own load all over Derek's godlike feet. Jack slowly spit out Derek's rod and fell to his knees, caressing his swollen belly. He looked up at Derek - so powerful, so dominant, so huge.

"So..." Derek was still out of breath after his orgasm, as huge beads of sweat were rolling down his face. "You're shrinking down?"

"Yes, Sir." Jack slowly shrunked back.

Derek did so as well. At his normal size, he suffed some pretty severe post-nut clarity, as he stared at the shocked crowd.

"Oh, I am so tweeting this shit!" some guy with a purple undercut yelled out.

"Okay..." Derek pulled his pants up - they easily scaled back and forth. "Unfortunately, Jack, you're a dumbass, so we'll have to drag you home naked."

Jack smirked.

"Okay..."

"And if you call me Daddy, I'm smashing you into the pavement," Derek warned. "Sir was already far too close for comfort."

Derek looked at Ash. The little femboy had a very interesting look on his face, the kind one only gets from watching your two roommates transformed into giants and acting out a gay sex show in public.

"Fuck, I have spank bank material for months..."

"Okay, gang, we're going home..."

He took off his jacket and put it on Jack, and the trio went home.
