Dean shivered with nerves as his new alpha lead him into his new home. Castiel was huge compared to Dean, he seemed to nearly tower over the petite omega. Dean had always been small, his father had his growth stunted so that he could fetch a good price. Which he certainly had, Castiel had paid a fortune for him the day Dean turned 16.
“Strip,” Castiel ordered firmly. “You’re not allowed clothes in my house,” he explained. “If you’re a good little omega I will let you wear clothes in public.”
Dean bit his lip and nodded, starting to strip with shaking hands. “Yes, Alpha,” he murmured. When he was naked he peered up at the massive man, hoping he was doing well.
“You have nothing to fear,” Castiel said calmly. “As long as you can be obedient and submissive for me. Can you do that?” He cupped Dean’s chin in his huge hand.
Dean gave a small nod in the Alpha’s grip. “Yes, Alpha.”
Castiel’s eyes gleamed with lust. “I’m going to claim you now.” Without further warning he grabbed Dean and spun him, pushing him down over the back of the couch.
Dean whimpered as he felt thick fingers press into his hole, but his body responded eagerly to being manhandled, and he was quickly producing slick. He let out a soft moan as he was quickly worked open. Dean squirmed, feet not even able to touch the ground.
Castiel’s fingers were suddenly gone, and the next thing Dean felt was the Alpha’s huge cock pressing into his tight, slick hole. He cried out at the pain and pleasure of it, his mind swimming with the need to submit to the powerful Alpha taking him. Castiel pulled out and thrust in harder, and his massive cock was finally buried inside Dean. He paused for only a moment before he pulled out and slammed back in, fucking Dean roughly, claiming his mind and body.
Dean could only moan and cry as his new Alpha took and used him, it felt better than he ever imagined it could.
All too soon the huge Alpha’s knot started to swell and fill Dean’s ass, and just as Castiel was about to come he bent to bite hard on Dean’s neck. The claiming bite was all it took to push Dean over the edge, and he came with a shout.
Castiel let out a satisfied groan as his knot tied inside Dean and his come started to pump the omega full. With a smile he wrapped an arm around Dean’s waist and stood, easily supporting his little mate’s body in one strong arm.
Dean whimpered as the knot pushed deeper inside him, his feet dangling in front of Castiel’s legs. He was almost entirely hanging from the knot in his ass, and it was making his mind fuzzy with submission and pleasure.
“You’re going to spend the whole day on my cock, little omega,” Castiel promised.
And he kept that promise. Later that evening found Dean still hanging from Castiel’s knot, the omega had actually lost track of how many times Castiel had fucked him. In between knots the Alpha would make him sit on his spent cock, keeping all the Alpha seed plugged up inside him. They’d sit like that, just talking, until Castiel’s cock would grow hard inside Dean and the Alpha would flip him over and fuck him again.
Dean whimpered as he hung from Castiel’s knot again, seed steadily pumping into his belly. Castiel sat relaxing on the couch, his hand on Dean’s ass, admiring the way his knot filled it. Dean’s face was pressed to the soft carpet, his ass up in the air. From this position he could see the round fullness of his stomach, full and growing with his Alpha’s seed. Dean moaned as more come continued to pump into him, continuing to fill him up.
“What a good little omega,” Castiel praised. “You love being full of come and cock. I should keep you like this always, shouldn’t I?”
Dean moaned into the floor. “Yes, Alpha,” was all he could manage.
