This is not you're normal body switch fanfiction, friends.
Things to know: Peter lives with the Avengers.
Peter woke up with a start, he was in a room he didn't recognize. The first thing he noticed was that the room was so messy. Whoever owned this room did not know what personal hygiene was. There was a foul stench coming from the sheets of the bed. It was coming from the substance that was next to him in a napkin. "Is that...cum?" Peter mumbled, disgusted. He quickly scrambled out of the bed, eager to get away from the white substance. "Where the fuck am I?" Peter didn't notice it before, but his voice was different. It was a tad bit lower than his own. He also noticed that his clothes were different. Peter walked up to the mirror, his mouth dropping open in shock when he saw his face.
That wasn't him. That definitely wasn't him.
Peter knew exactly who it was. Peter staggered back in shock. "H-how did this happen?" Peter looked at his hands, most definitely not his own. "Oh my god, I'm in his body. Does that mean he's in my body? How did...?" Peter looked back at the mirror, still not believing his eyes.
Flash fucking Thompson was staring back at him.
Peter wasn't sure if he should cry or scream or just die right there and then. He honestly wanted to do a combination of all three, but his body was frozen in terror. Flash was probably terrorizing his family. He needed to find Flash, fast. His best bet was to go to school and pray that Flash--er Peter was there. He dug through Flash's closet, looking for something to wear.
What would Flash wear?

Flash woke up in a daze. His room smelled...nicer than it usually did. Flash slowly opened his eyes and was surprised to find that he was in an unfamiliar room. Flash's eyes drifted to a mirror and he nearly fell back in shock. That was, no, HE was Penis Parker. "What the fu--"
"Master Parker-Stark?" A voice called out. Flash screeched and fell off the bed.
"WHO SAID THAT?!" Flash looked around frantically. "SHOW YOURSELF!" Flash's voice cracked and he cursed Peter for not finishing puberty.
"It's only me, Peter." The voice called out again. "Are you feeling alright? Would you like me to call Tony?"
Flash remained silent, too shocked to sat anything. He needed to think, if he was in Peter's body...then that means...
Flash gasped and grew angry. That pussy was in his gloriously attractive body! He punched the ground and let out a groan of frustration. Suddenly the door opened and Flash gasped at who it was. "Kid? Friday said something was wrong? Are you okay?" Tony asked as he walked in the room.
Flash backed away, eyes wide, finger pointed at Tony. "You're Tony Stark..." Flash whispered to himself. Tony tilted his head curiously. "OH MY GOD!" Flash jumped up and attempted to fix his--well, Peter's hair. He rushed over and furiously shook Tony's hand. "M-MR. STARK IT'S SUCH AN HONOR TO MEET YOU!"
"Uh, kid? You feeling alright?" Tony asked cautiously. "And I thought we were done with 'Mr. Stark', you were calling me dad yesterday." Flash was still shaking Tony's hand. Tony grabbed Flash's hand and gently made him stop."What do you mean it's an honor to meet me? Kid, I'm your dad."
Flash's eyes widened. Penis was telling the truth? "D-Dad? You're my...?" Flash nearly passed out, he had been bullying Tony Stark's son?
"Are you okay? Do you need me to call Bruce?" Tony put a hand on Flash's shoulder. Flash decided it would be best if he just pretended to be Peter until he could find out what was happening.
