It was probably the most unusual argument you have ever been in. You and he glared daggers at each other from across your joint shoulder, just a few mere inches. Both of you kept a vice grip on your single dick, neither you or your twin wanting to relinquish control. You tugged on your dick, harder than you intended, and pulled more toward your side. Somehow, you thought that pulling it closer to you meant more ownership of it.
Your twin must have had a similar thought process because a moment later you felt him yank, harshly, your shared dick to the left. This back and forth kept going for a many long seconds, with no winners. "Stop it..." You paused, still not sure what to call your other half. "Just stop it! Let me finish. You're going to make us lose our boner."
"You stop!" He exclaimed. "Its my turn!"
You were barely able to remain standing. The two of you had changed tactics, trying instead to pull your entire body in opposite directions. All the while, your shared boner was slowly receding. "We're loosing it! Your twin stopped abruptly, and the two of you toppled to the ground. "Stop fighting me for a second!"
You stopped trying to pull your shared penis and half of the body away. "What?" you questioned, still noticing your twin's strong grip on your penis.
"We both work it, okay? Fighting each other is not helping the situation. We share it, so we should share responsibility, deal?" Your twin said breathless.
"Deal." You agreed. The two of you, verbally agreed to let go at the same time, and move to the toilet.
Standing in front of it, you both grip your penis again, but this time try to synchronize your efforts. Within a few moments, you were back to a full boner. Reaching their climax, they angled their dick towards the toilet bowl and pumped vigorously. Their ejaculation felt twice as good, maybe even better since they were working together. They stood their for a moment with matching grins. "Okay" You finally say, "That felt amazing. Fighting wasn't fun, but that last part..."
"Was great!" your twin finished. "It was better than when we were..." He paused, appearing not sure how to phrase the last part.
You knew what he meant thought. "It was way better than when there was only one one us, before splitting ourself into two... or somewhat two people." You shrugged. "Anyways, your idea of joining our dicks was good. I wasn't sure at first, and our fighting didn't help. But, it did work out. If we can learn to share it, then I wouldn't mind only having the one."
Your twin beamed; he seemed to like that idea. "Good, then you can share in the clean up."
You chuckled, but helped your twin. Finished, you both turn and walk, which was a little easier to coordinate, back to your room; the katana handle was still lying on your bed. You looked inward to your twin, "You know, I still don't know your name, our names. We can't both be Jason, so what are our names?"
"This is a new reality. Let's check things out around the house, maybe we'll get that answer." He offers.
"Good a plan as any." You say. Before the two of you go exploring though, you agree to hide the katana, placing it into a drawer and locking it.
