You decide to enter Joey through his dick. Joey's DNA forces you to think as dirty as him which disables you to not like to idea of entering his dick. "Yeah baby, here I come" you say in a way Joey would have said it and you slowly move your slime to the front side of the underpants. Your mass is now surrounding his dick giving you the opportunity to form a thick thread of slime ready to dive into his erect cock. "Hold on tight" you grin as you have never grinned before and you launch yourself into Joey's member. "Arghhh" Joey moans in pain as you enter his meat and he grabs at his dick. "You can't stop me buddy" you say as you move more and more of yourself into Joey. "Ungggg." Joey is holding on tight to the side of his bed, trying to keep himself from fainting from the pain.
*Slurp* Your slime makes a slurping sound as the last of it enters Joey's cock. You are now completely out of the underpants and inside Joey. Joey is laying exhausted on his back and stares into the distance, recovering from the event. "You're mine now" you pervert mind says as you start to take control of Joey's body. "Ahhhh" Joey moans as he gives up the fight allowing you to take total control of him. "Hmmm... Yeah" you say in your newly acquired voice. You take a look at your new stiff cock and give it a good squeeze. "Unggg" you moan in Joey's voice. "This body is perfect" you say influenced by the DNA from Joey's pre cum. "We're gonna have a lot of fun together" you say as you think about your next move.
