A/N: Thank you to everyone who has reviewed! And, btw… This story is henceforth M, due to man-sex, :P It's actually deciding to turn out much more smutty than I intended, :P
Alec's eye's widened as he saw Jace's member spring free of its cloth prison, over eight inches long, rock hard, and a single pearly drip of pre-cum dripping from the tip. Alec had to hold Jace's hips down as he tried to buck up toward Alec, lost in his need for friction—or in this case, Alec's mouth.
Alec looked up at Jace before leaning in towards his cock, he reached out a hand and gripped it around the shaft, giving an experimental stroke, trying to gauge Jace's reactions to his ministrations. Jace bucked up into Alec's hand, a low moan hissing from his lips. Alec grinned at how responsive his parabatai was being, and then darted out his tongue, tasting the semi-sweet taste of Jace's pre-cum.
Alec mouthed the head of Jace's member next, before taking it into his mouth, stopping barely down the shaft, on the verge of gagging. Jace hissed, doing all he could not to ruthlessly thrust into Alec's mouth. Slowly Alec moved back up, applying suction as he went, then lowered his mouth again, before setting up a quick pace, bobbing his head up and down on Jace's cock.
Jace let out a low, throaty moan, loving the feel of Alec's mouth on his throbbing member. Just as Jace was about to start thrusting up into his mouth, Alec pulled off, grinning down at Jace when he heard his whine at the loss of contact. "As much as I hate to stop, I have needs too." Alec said with a grin and wink, before unbuttoning and unzipping his pants, then pulling them off and dropping them carelessly to the ground, then crawling over to Jace and doing the same.
Once they were both naked, Jace sat up, pulling Alec into a kiss, then, suddenly, found himself on his back again, Alec's naked thighs on the outsides of his own, and their throbbing needs pressed together in sweet skin-on-skin contact. Jace realized how this would be going, and found himself just fine with it. Then, all rational thought fled as Alec was kissed him again, hovering just inches above him, his arms braced on either side of Jace's head.
