You look at your older brother laying naked in the bathtub. "Let's have some fun together, shall we." You step into the bath with one leg. The water is still warm from jerking Joey off. You step in with your other leg and slowly sit down in the tub. Joey is laying with his legs spread allowing your small body to sit in between them. You take you 8 year old hand and move it underwater to your big brother. You feel around and bump into his balls. Smiling, you softly squeeze Joey's package and the move up to his member. Slowly, but intensely you start stroking his cock. Your tiny hands just fit around his member.
"Unggg..." Joey starts to moan. "What is it big brother? Doesn't it feel nice?" You ask Joey whilst pumping his dick. Joey slowly comes back to his senses. Suddenly his eyes open wide as he realizes what you're doing.
"How did I get here!? Why am I naked?! And What The Fuck are you doing?!"
"I am giving you a massage." You say with your innocent voice.
"You were fucking jerking me off!" Joey yells.
"Didn't you like it?"
"No! Well... Maybe... A little..."
Joey start to stutter a bit and turns red as he covers his member. You stand up in the bath and walk over to him. "Hey, what are you..." you push away his hands and fold your borrowed mouth over his erect cock. Joey gasps and freezes. "What are you Unggggg...." You start to suck on his member. Joey closes his eyes from the pleasure and relaxes his arms. Now he's off guard you take your opportunity and move your tiny over his balls. Joey thinks your tickling him, but you have a different plan. As soon as Joey moans again you shoot your hand past his balls and into his ass. "AHHHhhhh...." Joey screams. Your small hand has disappeared entirely into your big brother's ass.
Influenced by Joey's own personality, you start moving your hand around in his ass. "Ungggg.... Stop... Please...." He groans. In reply you smile, and push your hand further into his ass. "Ahhh..."
You can feel Joey's dick is starting to push. "The cum is coming" you think and give him a final blow. Joey moans and releases his cum bomb into your tiny mouth. You quickly start swallowing your brother's semen, but Joey releases so much cum that it starts to flow over your 8 year old cheeks. You continue swallowing as fast as you can. Inside Carl Joey's cum starts to mix up with your slime. Turning your personality into an almost exact copy of Joey's. As the cum stops coming and you've swallowed the last of it you take a deep breath. Joey carefully sits himself down into the tub to recover from his little brother giving him a blow job.
But you aren't done yet. You make Carl bend over again and wrap your little mouth over Joey's still erect cock again. "Wha... What are you doing?" he asks you. But you don't answer him. "You'll see soon enough" you think and start to send you slime into your tiny mouth and throat. You start blowing Joey's dick once more, but this time you send all of your slime up his dick. "Arggghhhh" you cries in pain as his dick increases in size by your slime passing through. You slowly start to feel Joey's body parts again. "Please.... Make it stooohhhhh....." Joey faints as you force the last of your slime into his dick. Everything goes black.
You open your eyes and gasp for air. You sit yourself up straight and see your 8 year old brother laying unconscious in the bathtub before you with his mouth around your new member. "Heh heh..." You start to push your dick up and down inside Carl's mouth and press his unconscious head against your crotch. "You like that baby brother?" you say in Joey's voice. You take your dick out of Carl's mouth after you have had your fun. You step out of the bath and look into the mirror. "Here I am again handsome!" you say as you move your hand through your hair and wink at your new body in the mirror. You dry yourself and walk back to Joey's room.
"What shall I do next?" you wonder.
