Work Text:
He had tried several methods to shut Zack up, some of them had not been very successful or long lasting, others had worked moderately well, and some had backfired on him because now Zack was running around trying to use pressure point pinch on others - and then he didn't shut up for hours when he finally managed. Admittedly, Shadowsan was both mildly surprised and extremely proud of Zack for that one, but he would not let Zack know that lest it got even more to his head.
So he had nearly exhausted all of his options and ideas to make Zack shut up, but as luck would have it Zack was the one that brought up the latest idea. He had tried to backtrack on the words that had slipped out of his mouth by accident, stumbling over his words, his entire face as red as Carmen's coat, and it made it even more obvious that his accidental proposal was more than just a slip of the tongue.
A tongue, it turned out, that was indeed very talented - and one that he was exceptionally good at holding still with the right motivation.
Shadowsan turned the page in his book, now nearly finished, and returned his hand back to Zack's hair, absentmindedly stroking it, eliciting the smallest of noises from the boy. When he had started reading, Zack had occasionally still lifted his head up, asking if that was really enough, if he shouldn't do more instead of just holding Shadowsan's cock in his mouth, but now a good hour later he had entirely quieted, content to kneel at Shadowsan's side and keep his mouth wrapped around Shadowsan's cock. So he was able to learn and keep still for some time, which perhaps warranted a reward after all.
He put the book aside and gently pulled on Zack’s hair to give him the go ahead to do more with his mouth. Zack let out a sound that was close to a sigh of relief mixed with hunger and greedily started to suck him off.
It didn’t take long for Shadowsan to grow hard and get lost in the sensation of Zack’s eagerness.
"Zack," Shadowsan said sharply and it made Zack's eyes snap up to his face, pupils blown wide still but clearly paying attention to his words now and not just his cock. "I am very close, so if you-"
Zack cut him off, eyes watery and voice strained, “No- no- please, please let me- just please I want you to come in my mouth, down my throat, please- I need-” Zack swallowed heavily straining against the hand in his hair. “Just please,” he begged.
Shadowsan swiped his thumb over the side of Zack’s mouth where there was some saliva clinging to the skin and watched with impassioned eyes as Zack’s eyes fluttered close, his mouth going slack and dropping open, another whimpered please slipping out.
“Very well,” he finally said and guided Zack back to his aching cock and Zack swallowed him down as if he was starving for it. Zack moaned around his cock, his motions again getting sloppier and desperate and so Shadowsan grabbed his hair harder again held him in place. Zack immediately reached up to grab his knees, as if he wanted to prevent Shadowsan from pulling his head away again, but this time he had other plans. Between the cast his leg was still in and softness of the couch it wasn’t precisely easy to pull of what he wanted to do, but he was himself determined and still in good enough shape for lifting his hips far enough to fuck into Zack’s mouth with deep, measured thrusts.
When Zack caught on to what was happening a high keened sound escaped him and then to Shadowsan’s surprise and delight he went limp enough so it was easy to fuck into his throat, use him for his own pleasure. Finally, his orgasm washed over him, coming inside Zack’s mouth. When his senses recovered he noticed how Zack was dutifully swallowing everything down he had given him and then his tongue moved over Shadowsan’s softening cock in little kitten licks to clean up any possible remnants.
“Well done, Zack,” he said, his own voice rougher than usual, and he felt the boy shudder. Finally Zack slowly let Shadowsan’s cock slip out of his mouth and helped him tuck it away again in his jeans. When he was done, he rested his head on Shadowsan’s knee, still oddly quiet.
“Zack?” he inquired when the silence stretched. It turned out when Zack was actually entirely quiet it was rather unnerving.
“That was good, yeah?” Zack’s voice was muffled against his leg.
“Exceptionally,” he allowed himself to admit, the praise entirely warranted. Zack blinked up at him, surprise morphing into a dopey smile.
“Yeah?”
“Indeed.”
“‘m glad,” Zack muttered, rubbing his cheek against Shadowsan’s jeans.
It occurred to him then that maybe offering something in return might be courtesy. “Would you like me to lend a hand?”
Zack turning his head away was not the reaction Shadowsan expected. “I- uhh- that- see- I’d love too? If you did- I mean- it’s just- just not- '' Zack sighed almost defeated, with each stammered word his ears turning redder. “It’s not necessary,” he finally mumbled and Shadowsan felt not a small amount of pride course through him at having ruined that boy so utterly with barely laying a finger on him.
“Good boy,” he said in a low voice and watched Zack shiver, his eyes turning up adoringly to Shadowsan but still he remained quiet, which was rather easy when you knew how to pull his strings right. Something dark coiled in his stomach, something he had tried to ignore ever since he left behind VILE island. He had always had a vicious streak to him, but ignoring it completely may not be the right way forward either. Perhaps though it could be redirected in a more beneficial way than crime.
“Stay like this until I finish my book and I might still lend you a hand.”
Zack’s eyes widened. “Really?!” after the quiet before Zack’s voice echoed even louder through the room. Shadowsan winced and so did Zack. “I mean,” he continued a lot quieter. “I- yes, that would be wicked awesome.”
Shadowsan snorted at the choice of words but instead of commenting on them picked up his book again. After a moment Zack’s head settled against his knee again and Shadowsan absentmindedly ran his hand through the boy’s hair.
