[With a few more desperate pumps, hot cum comes gushing out of Killua's hard, pink, cut little cock onto his hand. At the same time, he's biting back labored breaths, heaving needily in Killua's ear and pecking his hot cheek. He pulls back, his eyes glued to the point where Killua's cock is animalistically thrusting against his butt. He's amazed by the sheer force of those hips, wishes he could feel it from his own body. The mounting euphoria pools in his stomach until naturally, as if it's something he'd done his entire life, he hisses out a swear.]

F-fuuuuck--

[One more motion sends him spilling over the edge, staining the front of his shorts with a big load of cum. He stays glued to him for a while before pulling away and setting the other boy down on the floor, his chest rising and falling with big breaths.]

You..hah..made me swear!
