Jake was completely disoriented, having been stuck inside Kyle's underwear all day as he randomly continued moving about. Walking. Sitting. Walking some more. He could hear muffled conversations he would have with other people. He was talking about a new Marvel movie coming out with a girl, as if she were interested in that sort of thing.
Eventually, Kyle made his way home and to his bedroom. He finally unzipped his pants, and bright daylight filled Jake's vision. He felt Kyle's large hand firmly yet gently grip his torso, as he lifted Jake's head up to see a large smiling Kyle looking down at Jake.
"So. How was your first day as my penis?"
"Boring. Could you please let me go?"
"Ok. Here's the deal."
Jake felt himself beginning to grow. And grow. And grow. He felt his balls turn back into legs, and regained motor control over his body. Eventually, he grew large enough, back into his former full-sized self, on his hands and knees as Kyle separated his actual dick from Jake's backside.
"Free! I'm finally free!" Jake celebrated as he quickly stood up to face the still-smiling Kyle.
"Not so fast," his smile widening even further.
Jake realized he was slightly shorter than Kyle. Kyle pointed down at his penis. It was a large and intimidating hunk of meat. Hot and heavy, bobbing up and down like a breathing monster.
"I changed my mind," he finished. "It wouldn't do to have a half-man, half-cock. Not when I'm dating the woman of your dreams; Lizzy."
"What!? You can't! I was talking to her first!"
"Well. That's just the thing. Soon, you won't be talking. Ever again."
"What do you mean?" Jake asked fearfully.
"See this thing attached to me? It's larger than it was before. But not TOO large. It's the perfect size. You're going back to my crotch. Forever. And this is exactly what you'll look like from now on. I just wanted to give you one final taste of what it was like being human. You'll be spending the rest of my life as THIS!"
"NO! WAIT! YOU CANT-"
Jake felt himself shrinking again, getting a closer and closer upclose inspection of his new form. His perspective seemed to have turned around, as his legs attached themselves and dissolved into Kyl's balls.
Jake was now lying flat on top of Kyle's penis, as his arms wrapped around it and began to be absorbed.
"No! You can't! Sto-"
Jake's buttocks and torsoe we're aborbed into the dick, and he could no longer speak. All the way up his spine, Jake lost his own body to Kyle's penis. His spine turning into a large vein.
Jake saw Kyle humungous mushroom-shaped penis head get larger and larger in his view, as his face got closer and closer to it. He tried to shout. To say anything. But it was too late. His jaw opened up for the final time, as his chin aborbed into the underside of Kyle's head. His throat absorbed into his urethra, as his mouth and lips became the piss/cum slit. Finally, Jake's head disappeared into the rest of the cockhead.
Kyle walked over to the mirror to show Jake his new form he will have to now live with. Even though no eyes or ears were present, Jake was still able to see, hear, and feel.
"Take a good, long look at yourself," Kyle said amusingly as he lifted his head to like straight at the mirror. The only thing Jake could see, was a ref LL action of Kyle holding his penis. From the perspective of said penis! Jake was
now nothing more than Kyle's giant penis, and there was nothing he could do about. All he could do, was gently rest on Kyle's huge, soft, warm, right hand and stare at the monstrosity between Kyle's legs.
"NOOOOOO!" Jake secretly shouted in his mind. Kyle finally let his go, as his limp form slowly dropped down to be stuck looking at the floor, and a couple of large feet attached to long legs that seemed like a long ways down. Jake felt vertigo for a few moments due to his fear of heights. But he was completely attached to Kyle, and it would be impossible for him to fall from this height.
