Tuck found himself growling lowly as he slid into Eaton's heat, moving completely inside as his smaller counterpart took in a shaky breath; then exhaled with a trembling moan. He was fiery hot inside, soft and tight and so wet that Tuck had to close his eyes for a moment to keep his composure.

"Knot me, A-Alpha."

Eaton keened and mewled, lips parting and hips moving against Tucks as he begged for more; legs wrapping around Tuck's waist as he tried him tighter, closer in. Deeper in.

Tuck thrust in hard, all control and thoughts of a slow love making gone as he leaned down and snarled into Eaton's neck; all dominance and feral instincts as he scraped his fangs across the still fresh bond mark decorating Eaton's neck.

Eaton shuddered and mewled out a moan; his omegan side answering to his alpha as his hole gushed slick around the hard length inside him.

It wasn't just Tuck and Eaton now. Their animalistic sides were the ones moving their bodies as they crashed together over and over in the primeval of ways.

"S-So big."

Eaton didn't have an ounce of shame in his voice as he bunched the sheets between his fingers just to ground himself against the pleasure, back almost arching off the bed and hips pushing to meet Tuck at every thrust as his alpha filled him over and over.

"So hot."

Tuck growled back, parting Eaton's legs even wider apart and thrusting in even further. His knot bumped against Eaton's hole, making the smaller male whimper as a shudder ran through him. He wanted it. He wanted it inside him now.

"Alpha."

He begged, demanding and desperate as he tried to make Tuck go deeper.

"You'll come all over yourself if I do."

Tuck teased, fangs glinting in the morning sunlight as his skin shimmered with a light layer of sweat. Eaton whined in response, shaking his head and moving his hips in an effort to try and take matters into his own hands.

"You'll beg me to stop once I get my knot in you. You'll whine and mewl for me to stop as you spasm around my cock with the pleasure from it."

Eaton wanted it even more now, he physically ached with the need as a single tear trailed down his cheek.

"I-I want it please I-aghhhh-"

He moaned desperately as Tuck finally granted him his need and sunk his knot into him, hole stretching to capacity as Tuck absolutely stuffed him full. Eaton shuddered, thighs trembling as he wrapped his legs tighter around Tuck for more support; fingers grasping at Tuck's shoulders as his mate slid fully into him.

The beasts inside them collided, possessive growls and snarls rumbling from Tuck's chest as Eaton whimpered and laid himself bare for his Alpha to demolish; nails ripping lines into Tuck's back and teeth biting greedily into his neck and skin, sucking and licking over his marks.

Because Tuck was his, his, his. No one else's.

"Mine."

He whispered through a growl, pulling at Tuck's short hair and gasping as he felt another wave of unadulterated pleasure ripple through him, the heat inside boiling over and causing a dribble of cum to ooze from his already dripping length.

He felt shaky.

Almost weak and breathless from the pleasure, all of it too much and not enough at the same time as Tuck continued to split him in two; making him come over and over and over until he couldn't tell when he was coming and when he wasn't.

His thighs were covered in slick and cum, gold eyes half-lidded and lips parted as he gasped for breath. Tuck was still all animal, gripping Eaton's hips firmly as he released another load of seed into his omega's stretched hole, growling with pleasure as he finally sated himself.

He chuffed, licking his lips and blinking as his eyes slipped back from icy blue to piercing red, a smile pulling at his lips as he looked at the debauched figure below him.

Eaton keened as he was filled again, feeling the river of his alpha's cum flow inside him and stay there.

He reached out desperately, meeting Tuck halfway as he was cradled into the taller man's chest and kissed; having the rest of his breath stolen by perfect lips and kind, whispered words of affection.

"I will love you always."

The words seemed even sweeter when spoken in his alpha's husky, sated, and completely fond voice; the both of them embracing in both body and mind as their beasts settled in; content and sated.

Eaton smiled, fingers trailing across his stomach to Tuck's hand, entwining their fingers and humming delightedly as their rings glinted in the afternoon winter light.

"And I will cherish it forever, my love."

The End.
