Kyle shifted around for a second. "You know what, bro? Join me, let's have a little fun."
Jeff spoke. "What?"
Kyle smiled. "Ah, that got you to speak! I'm going to make you part of me!" Jeff went silent—he didn't know what this meant in the slightest.
Kyle pulled his shorts and his underwear all the way off and lay down flat on the bed, still holding Jeff. He placed Jeff, balls and all, on himself, right beside his dick. Jeff had a good look at Kyle's rod and jewels—they were, surprisingly, identical to Jeff's.
Suddenly, Jeff felt a hot sensation at the base of his shaft, with Kyle also feeling a hot sensation where Jeff was in contact with his crotch. "You see, brother, you'll be a second cock of mine for a little while. Just so we can have a little bit of fun." Jeff's base connected to Kyle's crotch, becoming a second cock to the right of Kyle's existing cock, and his ballsack merging with Kyle's so Kyle now had four balls. Kyle ran into the bathroom connected to Jeff's room and began jerking off both cocks, one in each hand. "Oh yeah, that's the stuff," he panted as ropes of off-white cum streamed across the bathroom.
