Having confirmed that this was indeed not a dream, Jake exits his dad's body a briskly returns to his own room.
"I can possess people!" he whispered to himself, "I can possess people!!" He yelled out in excitement, quickly covering his mouth, however, it seemed that his dad hadn't heard him. "Maybe no one can hear me while I'm in, uh..." he hesitated as he looked down at this current, ethereal state, "ghost mode?"
Jake drifts back to his father's bedroom and finds him getting dressed for work.
"Dad!" he yells, but his father continues with his morning routine as he throws on a dress shirt, "Dad!!" Jason cries out louder, Adam's lack of response confirming Jake's theory.
The grin that'd spread on Jake's ghostly face quickly faded when he saw his dad open the door and head down the hall to his son's room. Moving as fast as he could, Jake slips into his room and re-materializes as his dad knocked on his bedroom door.
"I'm awake!" Jake calls out. His father entered the room and gave him a firm hug, Jake could feel his dad's strong muscles under his suit and regretted not having explored his father's body longer.
"Happy birthday, son!" Adam said happily, "Now, I know it's not much, but I have to leave soon and I wanted you to have your birthday present early. Hopefully I can leave work early and we can go have dinner, just you and me, yeah?" he said has he pulled out an envelope and handed it to Jake.
"Thanks Dad, you really shouldn't have," Jake said with a smile, whatever was in the envelope couldn't even come close to the other gift he'd received this morning, "and dinner sounds great."
Adam gave his son another bear hug before patting his shoulder and heading out to work. Seeing that he only had ten minutes before he had to leave, Jake quickly got dressed, grabbed his things along with the envelope and headed out to school.
Jake ran down to the bus stop and made it just as the bus was pulling up. After paying his fare and finding a seat, Jake opened his dad's gift and pulled out a birthday card, he opened it and found $100 inside and "Happy 18th birthday to my favorite guy. -Dad" in his father's handwriting. Jake smiled and put away the money and the card. Jake and his father were fairly close given how they only had each other for family. And even though Jake hadn't inherited his father's strong build or natural athleticism Adam never seemed to hold any disdain for his son. It was considering this that Jake remember the brief moment he'd spent inside his father's body and the strength and size he'd felt in it.
Jake was pulled out of his thoughts when the bus pulled up in front of his high school. Walking through the halls was completely different today. Where yesterday he might have looked around and seen nothing but students and faculty, today he saw potential.
He could possess one of the jocks, having had a small taste of pure, masculine strength left him craving it, and who better to satisfy that than the young, virile jocks of Merston High; he could explore what it was like to be a real adult and possess one of the many teachers on campus; or he could experience high school through the yes of a skater, or a nerd, or any of the other cliques that filled the school. Or, he could bide his time and explore his father's body again, this time taking his time to fully experience it.
