Ethan was stroking away at the cock he and Luke shared. Luke stared at their cock in shock as Ethan pumped away at it.
"Dad, stop doing this right now! I don't feel comfortable feeling someone else touch my dick, let alone masturbating with it!" Luke tried to use his hand to pull Ethan's away from their penis.
"Hey, you were the one that started it! And I'm just finishing the deed that you couldn't finish correctly." Ethan resisted Luke's attempt to halt his jerk-off session.
"Are you kidding me? I was doing it just fine! If anything, you're the one doing it wrong!" Luke stopped trying to pull Ethan's hand away, and instead put his hand on their dick, both of them now gripping it.
"Get your hand off it! You're screwing it all up!" Ethan now tried using hand to pull Luke's off their penis.
"No way old man! If we're gonna do this, we're gonna do it the way I like it!" Luke tried to work their dick how he did when Ethan was asleep earlier.
"Oh, to hell with that! We'll see about that!" Ethan tried pumping their dick at the same time Luke did, causing their hands to bump into each other.
There was no rhythm to their stroking. Both of them constantly lost grip of the penis they shared. All the while they were staring and yelling at each other, trying to prove that the other was doing it wrong.
"You're terrible at masturbating! You can't even work our cock correctly!" Luke head butted Ethan, Ethan's head recoiling from the sudden strike.
"Bullshit, I'm the one with the experience! You're bad energy is preventing us from ejaculating!" Ethan retaliated by kicking Luke's leg with his own.
At this point, both of them had let go of the dick between them, and instead their hands were pushing on each other's faces.
They were both trying to enforce their wills on their single body, fighting for control. The duo rolled around the bed sporadically, all while their penis was still hard.
Eventually...
