"You're not going to come," JC said, softly and matter-of-factly. "You're not going to come tonight." He bent his head, nuzzling at Justin's thigh, his lips warm and gentle against the tensed muscle, and Justin had to bite the inside of his cheek to keep himself from screaming.
"Because I said so," JC added, as if Justin had asked why, as if Justin had begged for a reason, and JC's hand tightened fractionally around the curve of Justin's hip. "Because you're so fucking hot like this," and damp, burning air hit the head of Justin's cock, desert wind from JC's mouth, and then Justin threw his head back against the pillows, eyes squeezed shut, as JC sucked him in, lips tight and fierce and his tongue curling smoothly around the ridge, curling and flicking and sliding.
Justin didn't know what to do, didn't know how to do it, how to convince JC to let him come. He was so hard in JC's mouth, he couldn't stop himself from whimpering, and JC was still sucking, god, taking him so deep, so tight and deep in JC's throat, silky and slow, and he was never going to come like this, it was maddening, it was terrible, and his legs convulsively shuddered around JC's body. JC laughed quietly, the vibrations on Justin's cock a thrilling electric blur, and stroked his palm down the length of Justin's thigh, fingernails scraping lightly, curving underneath at Justin's knee and lifting his leg. Justin moaned, his hands grasping at JC's shoulders.
"All night, baby." JC kissed the head of Justin's cock, kissed his way down to the base to swirl his tongue in a flat, wet circle, kissed his way back up. "I've got you all night, and you're not gonna come once, and you are going to love it." And Justin moaned again, because he knew JC was right.
