Chapter Text
Saix returned to his room to find his little sub (for the day) kneeling next to his desk naked. The boy’s bright blue eyes widened happily when he looked up at his Daddy. He bowed his head bashfully, feeling his collar rub against his neck, and waited for Saix to acknowledge him before speaking.
“Good afternoon, Roxas.”
“Good afternoon, D-daddy…”
The collar really helped get the stubborn boy into subspace, Saix noted. He moved to his desk, ruffling the boy’s hair briefly on the way, but otherwise paid him no attention. He had work to do, after all, and he couldn’t indulge his sub every second of the day. He began writing up the next day’s mission assignments while Roxas knelt quietly next to his chair.
After a good 40 minutes, Saix stretched his arms and swirled his chair back from the desk. He looked at Roxas, who had apparently been watching him but snapped his gaze away the second he turned around. He eyed the sub for a few moments. A thin, toned body, messy blond hair, a pretty brown collar around his neck. When his eyes moved to the sub’s obviously stiff cock, he spread his own legs and unzipped his coat and pants until his erection was freed.
“Roxas,” he beckoned, motioning the boy to crawl to him.
Roxas perked up immediately and shuffled over to his Daddy. He was rewarded by a firm hand in his hair.
“Kneel under my desk and suck me while I work.”
“Yes, Daddy,” he breathed. He clumsily scooted under the desk and took a moment to get comfortable in the cramped space. The older man pushed his chair back in just close enough to be serviced and gave the boy an expectant look before returning to work.
Roxas blushed and felt his mouth water when he came face to face with that thick, veiny cock. It was red at the tip–waiting, demanding. He needed it in his mouth, down his throat, dripping over his tongue… Wiggling in his spot, he leaned forward and placed a soft kiss to the head of Saix’s cock.
Wonderful. Saix hummed appreciatively and shifted his hips to get comfortable as Roxas began to lave attention to his cock. He had always been good at compartmentalizing, but with the gentle kisses and kitten-licks Roxas was giving him, it was a little difficult to concentrate. He was fully hard now. His balls were starting to tingle and ache, preparing a nice load for the blond boy’s lips.
The taste of pre-cum hit Roxas’s tongue like an aphrodisiac. It was a strong masculine musk that seemed to travel straight from Roxas’s throat to his dick. He began sucking harder, sinking his mouth down onto the slightly curved cock. His saliva mixed with the pre-cum and left the flesh gleaming as it slid in and out of his mouth. Veins throbbed against his tongue each time he sucked.
Meanwhile, Saix peered down at his sub with burning eyes. Those pink lips were wrapped fully around his length, stretched so obscenely they were sure to chap. A dusting of a blush covered Roxas’s whole face. Such a beautiful little boy.
“That’s it, Roxas, mmm… suck daddy harder.”
Roxas moaned around him in response. Pleased, Saix tore his eyes away and got back to work.
Suddenly, a large hand clasped the back of his head and pushed him closer. Saix began to thrust his hips up at a brutal pace, sliding against the ridges of the boy’s throat eagerly. He was still looking at his papers, but he could multitask; all he needed was somewhere warm and wet to thrust his dick, and Roxas’s mouth was perfect for that. The little gags and whines were an added bonus. He held the boy in place and let his hips move on their own accord.
“Such a good little cock slut,” he groaned, finally dropping his pen to grasp Roxas’s head in both hands.
The boy mewled and choked as his throat was fucked. The noises were absolutely divine to Saix’s ears.
He forced his cock in and out, in and out, while the organ pulsed happily and saliva leaked down Roxas’s chin and Saix’s balls slapped against his face–the soft, suckling pressure was too much too fast and Saix felt his release quickly approaching. Yanking his cock out with a loud pop, he didn’t give his boy any time to recover. He tugged at Roxas’s lower lip with his thumb.
“Open,” he growled lowly, “and drink Daddy’s cum.”
“Hnng…”
Roxas obeyed. Leaving his lips wide open for his Daddy, he closed his eyes and stilled his body. He knew he wouldn’t get any cum in his mouth if he wasn’t patient.
Saix bit his lip and placed the head of his cock just inside Roxas’s mouth. Stroking with one hand and fondling his balls with the other, he masturbated until he came in long, slow ropes inside the boy’s mouth. He could see each spurt slowly fill the boy up, marking him with his essence… it was a hefty, filthy sight.
Roxas moaned softly as warm cum began filling his mouth. It gushed around in his cheeks and got caught on his tongue as he tried not to swallow yet. He loved the taste–salty, bitter, and masculine. It was Daddy, feeding him his cum so he’d grow to be an even better boy for him. Mindlessly, Roxas arched his neck forward, needing to collect every single drop his Daddy had to offer.
Saix had been saving himself for this moment, and so had a lot of cum packed away for the boy. Each squeeze to his balls brought another jolt of pleasure up his spine and another hot glop of cum in Roxas’s mouth. He couldn’t contain his own swears as he rode the waves of his orgasm for several minutes before he finally had released all he had to offer.
The final product was astounding: Roxas, on his knees like an obedient sub, hands in his lap but not on his dick, with bulging cheeks and a mouth entirely filled with sticky cum. His face was entirely pink. After taking in the image and storing it away in his memory, Saix swirled his finger between the boy’s lips and pressed against his tongue. He wanted to make sure the boy was tasting his Daddy.
Finally, he gave the order to swallow and watched wide-eyed as the cum moved down Roxas’s throat. The boy opened his eyes and gazed up at him longingly.
“Did I do okay, Daddy?”
Saix felt almost half-hard again.
“Yes, you did very good, little one. Now crawl to my bed and start prepping your ass for Daddy’s cock. I’ll come fuck you once I finish this paperwork.”
Roxas nodded dreamily and moved without a second thought. This play date was by far the best thing Xemnas had ever arranged for him, and he couldn’t wait for Saix to tell his master what a good boy he’d been.
