Page 105 of Knot That Serious

Jack’s eyes stared up at him, darkened, pupils wide as he grasped Beckett at the base and rubbed his lips over the tip.

Beckett swallowed sharply at the sight, at the sensation of his plump bottom lip getting caught on the head.

Then Jack was parting those plush lips and taking him inside.

The wet heat of his mouth was heaven, and Beckett placed a hand on the mirror, far above Jack’s head, to steady himself.

God, he could just—he could just push Jack against the mirror and fuck his throat. Jack would let him.

But why do all the work when Jack was oh-so-eager, tongue swirling around his length as he took him in, lips meeting his fist circled around Beckett’s base, his lightly swelling knot.

“Fuck,” he breathed. “You’re gagging for it.”

Jack’s eyes snapped up, and then he uncurled three of his fingers from Beckett’s cock, taking him even deeper.

Beckett choked back a moan, watching more of his length disappear in Jack’s mouth, brushing against the roof of his mouth, the back of his throat. He bit his cheek when Jack swallowed around him, the cinch of his throat hot.

His abs tensed as he resisted the urge to thrust forward.

Beckett caressed Jack’s cheek, brushing a thumb over his chin to wipe away the drool. “Don’t want to drip on the pants,” Beckett said.

He felt Jack’s jaw work against the palm of his hand as Jack took him even further, until his hand was cupped around Beckett’s knot, lips flush with his fingers.

“A-fucking-plus,” Beckett said, the words scraping past his lips. He combed his fingers through Jack’s dark hair, stared at the way Jack’s dark polished fingers looked, obscene around his flared knot.

Jack shivered and began reversing his path. Was it the praise? The feeling of Beckett vacating his throat, heavy on his tongue?

“How am I doing, professor?” Jack asked, lips wet, breath warm as it ghosted over Beckett.

“You’ll get your grade at the end of the quiz,” Beckett promised, letting his hand curl a little more forcefully in Jack’s hair. “Keep going.”

Jack settled a little deeper on his knees, gaze a little heavier. Then he was sinking his mouth around Beckett’s length again.

Jack swallowed him with ease. “How are you so good at this,” Beckett breathed as Jack’s tongue swirled along the underside. “Such a slut for it.”

The hand not wrapped around Beckett’s knot was resting on Jack’s thigh, and as Beckett’s words sank in, his fingers went white as he clutched at his own skin. But he didn’t touch himself.

“Good boy,” Beckett said, and tried to keep his breath even as Jack drew off him again before sliding right back down. He opened his throat for Beckett on each draw, even hummed as his throat constricted around Beckett’s cock.

The vibration stirred the pleasure in him to new heights, a great swell in every sense of the words. His hand tightened in Jack’s hair, holding him in place, his nose brushing against Beckett’s groin. He waited, waited—wanted so deeply he couldn’t breathe for it—and loosened his grip, letting Jack take the breath Beckett couldn’t find as he retreated.

His fingers squeezed around Beckett’s knot, tongue laving over the tip and beneath, lapping at the notch below the head. “Don’t get distracted,” he directed, and used the fist in Jack’s hair to steer him. “Steady. Maybe one day you can stay like this, take your time. I can—“ He sucked in a breath as Jack took him deep, lips sinking and throat shifting around him, swallowing. “I can grade papers,” Beckett tried, and Jack’s gaze lifted, darkened. “Keep you under the desk,” he continued. “Warm me until I’m done with work.”

Jack whined quietly, aware of their surroundings but growing more desperate by the moment. There would be half-moons left in his own skin from his nails. He was hard, straining against the thin fabric of his boxers, but he didn’t make a move to touch himself, though his thighs flexed as if he were about to lift up, searching for some form of friction.

Christ, he didn’t know it would be like this. That Jack would be so… so pliant and needy on his knees, with Beckett telling him what to do.

“I hate that you’re at work while I am,” Beckett said suddenly, an idea crawling into his mind, and in the haze of Jack’s mouth around him, Beckett couldn’t think of a reason why he shouldn’t use this opportunity. “The only person around when I’m working is… Eli.”

Jack’s hand squeezed around his knot, eyes lifting again, beginning to water from the labor. And yet despite that, Jack’s fervor only increased, cheeks hollowing as he slid up Beckett’s cock and back down again, without pause.

“Do you think she’d like a good grade, too?” Beckett asked. “Would she go to these lengths, do you think?”

Beckett waited until Jack had taken a breath, nostrils flaring before he cupped the back of Jack’s head and sent his hips forward, slipping across Jack’s tongue and down his throat.

Beckett turned his gaze to the mirror, watched Jack’s throat wobble around him in the reflection. “Would she let me take such… liberties?” he asked quietly, pulling his hips away, the drag of Jack’s mouth too good, so Beckett thrust back in.

“I don’t think she would,” Beckett mused, whispering as he held Jack in place by his hair, fucking his mouth and throat with each word, the pleasure swelling, a balloon in his gut.
