Chapter 2.

"Yes Alpha."

Steve on hearing this bit down hard at the juncture of Tony's neck and shoulder, teeth breaking through skin and worrying at the flesh searching for the scent glands. His teeth pierced the glands a musky, woody flavour flooded his mouth mingling with the blood he swallowed it down, lapping at the bite his saliva mixing with the blood and scent excretion.

To ensure that his mark took and that the bond would be permanent he bit his lip and dripped his blood into the bite, smearing it on the scent gland where it would sink in and cause Tony's scent to change and ensure that any other Alpha knew that he had been claimed and not to touch him.

Steve slammed into Tony's raw puffy hole twice more before his cock pulsed and released his cum into the slick tight heat of Tony's rear.

Still hard he pulled out and sprayed more cum over Tony's pack his large hands smeared it into his skin, making sure to rub some over the already healing bite mark.

Flipping Tony over and pushing him down on his knees he pressed his thumbs into the corners of Tony's mouth forcing it open, he pushed his cock passed plumb lips and then forced it the rest of the way in filling Tony's mouth and throat. Ignoring the tear streaked face and Tony's frantic gasps for breath he set a fast pace, his cock continuously sliding down into Tony's throat with each thrust.

His cum flooded Tony's throat in a matter of moments, he could feel Tony swallowing frantically trying not to choke on spill any, he knew Tony would not be able to succeed there was just too much, he could already feel some spilling out of his lips and dripping onto his chin.

With a jerk he withdrew still pumping cum but this time all over Tony's face and chest. He rubbed it into Tony's skin even over the arc reactor, now there was no part of Tony's body inside or out that had not been marked by the Alpha.

Steve looked down at his quivering Omega he was a beautiful sight, gasping for breath covered in cum, tears dripping off his eye lashes his ass cheeks ruby red.

Steve checked the bonding mark, it was fully healed he would have to make a decision on whether to brand or tattoo his personal mark above it so that everyone would be able to see that Tony Stark was Captain America's Omega.
